Graphene oxide was synthesized via Hummer's modified method, and its surface morphology was characterized through FTIR spectroscopy and scanning electron microscopy (SEM). A systematic study of the adsorption process was conducted, varying pH, initial copper concentration, contact time, adsorbent dosage, and temperature. The experimental results revealed that the maximum adsorption capacity, with 89.77% efficiency, was achieved at a pH of 7 when 0.5 g of adsorbent was in contact with a 200 mg/L copper solution at 20°C for 30 minutes. The nano adsorbent exhibited a high adsorption capacity in both simulated and real industrial wastewater samples, effectively removing up to 99% of copper from industrial samples. Adsorption isotherm, kinetic, and thermodynamic studies were performed to elucidate the adsorption mechanism. The adsorption process followed pseudo-second-order models and the Freundlich isotherm. Thermodynamic studies indicated that the adsorption of copper ions on ZnO/GO was a spontaneous and exothermic reaction with an enthalpy of -6361.21 J/mol. This study demonstrates that nano ZnO/GO can be utilized as an effective, low-cost, and environmentally friendly nano adsorbent for electroplating wastewater treatment. Manuscript profile -

Eight hundred specimens of rainbow trout fry (17.22±5.41 g) were randomly distributed in 18 experimental tank (six treatments each with three replications). The basal diet was prepared without zinc supplementation and used for the negative control treatment. Other experimental diets were prepared by adding 10, 30, 50 and 70 mg/kg of zinc nanoparticles and 70 mg of zinc sulfate (positive control) to each kg of the basic diet. Blood samples were taken from the fish at the end of the experiment to check the number of white blood cells and their differential count. After two weeks of adaptation, the fish were fed for 8 weeks with the diets corresponding to each experimental treatment. Blood samples were taken from the fish at the end of the experiment to check the number of white blood cells and their differential count. The results showed that nano zinc oxide has a significant effect on the leukocyte count with the highest number of 178,000±22,000 No. mm-3 in fish fed diet supplemented with 50 mg kg-1 Nano ZnO, which was significantly more than their number in fish fed with basic diet (p<0.05). Furthermore, fish fed diet supplemented with 50 mg kg-1 Nano ZnO diet had the highest lymphocytes percentage of 72.21±0.13%, while the lowest percentage of neutrophils was also found in fish fed diet supplemented with 50 mg kg-1 Nano ZnO. However, the actual number of neutrophils in the blood of fish in this treatment was 4.5 folds more than those in the negative control treatment. Findings of the present study showed that zinc oxide nanoparticles have a significant effect on the leukocyte properties of rainbow trout. Manuscript profile -

Water is an important component in all physiological processes of the should be added, accounting for 80 to 95% of the plant’s biomass. Except in high humidity environments, plants are likely to be exposed to water deficit stress throughout their life cycle. water deficit stress decreases the quantity and quality of the plant product and in addition reduces the water use efficiency as well as reduced the absorption of nutrients. to reduce the effects of water deficit stress on plants, various methods are used, including mineral nutrition with trace elements such as zinc.Method: to investigate the effects of foliar application of zinc on the morph physiological and biochemical traits of safflower cultivars under drought stress, an experiment was conducted as a should be added split-plot based on of should be deleted randomized complete blocks design with three replicates during 2019-2020. Experimental factors include drought stress as the primary factor, and safflower cultivars and zinc foliar application as secondary factors. The plant’s canopy temperature was determined using an infrared thermometer. Seed oil was extracted from the mature seeds of safflower cultivars by the should be added apparatus using hexane solvent.Results: Water deficit stress was applied in two levels (regular irrigation (control) and irrigation cut-off when the grain filling stage begins); safflower cultivars in this experiment were Isfahan, Linas, Padideh, Parnian, and Goldasht; foliar application of zinc was in three levels (0, 0.5 and 1 kg. ha-1 Zn). Results showed that water deficit stress decreased stem diameter, head diameter, number of classes per plant, number of seeds per plant, seed yield, biological yield, oil yield, relative leaf water content. Whereas, water deficit stress increased the should be added of the should be added environment. Foliar application of 1 kg. ha-1 Zn improved seed yield, biological yield, oil yield, relative leaf water content.Conclusion: The results of this study showed that the water deficit stress significantly decreased the growth rate and consequently biological yield, oil yield, and relative water content (RWC) of safflower plants and on the other hand, the application of zinc under optimal irrigation (control) and water deficit stress improved the mentioned traits. Based on the obtained results, it can be stated that the application of zinc can be one of the appropriate solutions to mitigate the effects of water shortage in the grain filling stage of the studied cultivars of safflower.

In this study, the applicability of ultrasound assisted emulsification microextraction was explored as a simple and fast method for the preconcentration and determination of Cu2+ and Zn2+ ions. Materials and Methods: One aliquot of sample solution was poured in a screw cap glass tube with a conical bottom. Then, the chelating agent and extraction solvent were injected into the sample solution using a syringe in the ultrasonic bath. Disruption of the emulsion was carried out by centrifugation, and the sedimented organic phase was transferred directly to the graphite furnace atomic absorption spectrometry for determination of Cu2+ and Zn2+ ions. Results: 3-((6-methyl-5-oxo-3-thioxo-2,5-dihydro-1,2,4-triazin-4(3H)-yl)imino) indolin-2-one was introduced as a new and selective chelating agent. Parameters that affect the extraction efficiency, such as the kind and volume of the extraction solvent, volume of chelating agent, sample pH, extraction time are optimized. Chloroform as extraction solvent give the best results. Under the optimum conditions, the calibration curves were linear in the range of 0.05-1.5 μg L-1 ions. Relative standard deviations were 2.9 and 3.5 for five analysis of sample solution containing 0.1 mg L−1 Cu2+ and Zn2+, respectively. The detection limit of method was 0.043 for Cu2+ and 0.045 μg L-1 for Zn2+. The effect of presence of other ions was investigated. Conclusion: The results demonstrate a successful method for quantitative and selective determination of trace amount of Cu2+ and Zn2+ ions in water and food samples. Manuscript profile -

The objectives of this research were to synthesis Manganese dioxide nanoparticles and determining its efficiency in the removal of Zinc from aqueous solutions. Methods: Consequently, Manganese dioxide nano-particles were synthesized using cathode electrochemical deposition method and the effects of pH, contact time, MnO2 concentrations as well as Zinc concentrations were investigated on Zinc removal efficiency using a batch experiment. XRD, FT-IR and Scanning electron microscope (SEM) were used to identify the characterization of synthesized Manganese dioxide nano-particles. Zinc adsorption isotherms were investigated using Langmuir’s and Fruendlich’s equations. The Zn Kinetic isotherms were also studied using Hue et al as well as Lagergren models.Results: SEM results showed that the diameter of nano-particles was 30 to 50 nm. The other results showed that Zn adsorption and its removal were increased with increase in pH and was reached to the maximum amounts of 90/4 % Zn removal and the optimum pH value for adsorption was 6. Contact time has also enhanced the Zn adsorption. The adsorption capacity increased and the adsorption efficiency slightly increased with increasing concentration of Zinc and reducing the adsorbent. Experimental data were shown the best to follow Langmuir model. Langmuir adsorption capacity was found to be 285/71 mgg−1. The results also showed that the absorption of Zinc was obeyed from pseudo-second-order kinetic model.Discussions: The overall results showed that the use of Manganese dioxide nano-particles could be suitable materials with high potential to removal Zinc from aqueous solutions.

Method: In this study, the 6EPA standard method was used and tested 7 times around the water and soil around the area and was expected to have adverse environmental effects, like other lead and zinc mines in the country such as Angoran and Zahabad. Finding: Studies have shown that the amount of lead in soil and water is standard for agricultural use and has little environmental impact. Discussion and Conclusion: Based on stratigraphic columns prepared in the Surmeh Mountains containing the salt marshes of the Hormoz and calcareous Dalan Formations and the Nare Evaporites, the tectonic effects of alpine activity acting in two tensile-shear and compressional conditions have resulted in the Dalan calcareous formation containing ore deposits. Lead and some clay minerals are marl, located in the core of the Surma anticline which provides salt diapirism conditions in different tectonic phases and eventually due to the calcium carbonate uptake in the Dalan Formation and the high uptake capacity of clay and salt minerals in the lead. Higher levels prevent lead release in groundwater and its derivatives in confined air and soil. Thus it can be said that the regional tectonics has resulted in the creation of a natural filter for active adsorption of lead in the range. Manuscript profile -

Cadmium and nickel are among the heavy metals that are harmful to human health in high concentrations. Removal of bio-pollutants from these wastes is one of the concerns of the zinc industry. The purpose of this study is to remove nickel and cadmium as impurities in the zinc production process by cementation method.Methodology:The procedure consists of three steps: cold purification cake leaching, impurity purification and electrolysis. The cake is first liquefied with sulfuric acid and the resulting solution contains zinc ions along with nickel and cadmium impurities. Optimal conditions for the removal of impurities were obtained by the surface response method (RSM), then the filtration process was performed by the cementation method and the impurities were removed and finally the solution was electrolyzed to produce zinc. Using Design Expert (DOE) test design software, the parameters affecting the filtration process such as temperature, zinc powder concentration, retention time and additive concentration were investigated.Findings: It was found that most influences related to contact time, temperature, zinc powder amount and additive concentration, respectively. So, optimum conditions for removal of nickel and cadmium containing temperature of 85 centigrade, concentration of 6.63 mg L-1 of zinc powder, contact time of 100 min and concentration of 10.29 mg L-1 for additive were obtained. At these conditions, impurities amounts were reached to the allowed limit for electrolysis and zinc in the cake was recovery.Conclusions: Using cementation method by removing impurities and then recovering zinc, in addition to solving some of the environmental problems caused by the cake, the recovery of these metals is of great economic importance.

Material and Methodology: The amount of the mentioned metals in 419 wheat samples, after preparation and extraction, was analyzed by atomic absorption spectrometry. Findings: The amount of cadmium in the 8.59 percent of wheat was higher than permissible limit in national standard index of Iran (0.03 mg/kg). In all provinces, the average amount of cadmium was less that the permissible limit, except Gilan. The findings showed that the amount of lead in 0.72 percent of analyzed samples was higher than permissible limit in the national index (0.15 mg/kg). In all provinces, the average amount of lead was less than national index of Iran. Analysis of concentration of zinc, a useful element, showed that in much of samples (about 79 percent), the concentration of this element less than acceptable level (30 mg/kg). Discussion and conclusion: The analysis of frequency distribution of heavy metals in different provinces of Iran showed that in Gilan province, the concentration of cadmium is more than permissible limit. Since that the permissible concentration of cadmium in the national standard of Iran is unreasonably exigent. It is suggested that the maximum tolerance limit for cadmium in wheat grain should be reviewed. If the Codex standard is considered as an indicator of the pollution of heavy wheat production in Iran, in relation to cadmium, none of the analyzed samples cadmium concentration has not exceeded the Codex limit. In addition, the results of zinc measurement in wheat samples indicate zinc deficiency in most of the samples. Therefore, regarding the share of bread in the food basket of Iranian society, increasing the concentration of zinc in the wheat of Iran should be taken into consideration. Manuscript profile -

It is important for the phyonsiological functions of living tissues and regulates many biochemical processes. However, excessive zinc can cause eminent health problems. The aim of this study was to investigate zinc removal from aqueous solutions using chitin extracted from carapace crab shells. Methods: To study the removal of zinc, chitin extracted from carapace crab shells was used as biosorbent in a batch system. Also the influence of pH, initial metal concentration, amount of adsorbent and contact time on adsorption process was investigated. Results: The results of this research showed that the absorption capacity of zinc closely depends on the pH of solution, because zinc absorption concentration (mg/g) increased with the increase of pH. The maximum biosorption capacity of Zn2+ onto chitin (181.181 mg/g) was obtained at biomass dosage of 4g/L and contact time of 180 min. The result showed that removal efficiency of zinc was decreased by increase of initial zinc concentration. The results of equilibrium studies revealed that zinc absorption process on the extracted chitin was desirable and followed the Freundlich isotherm model and pseudo second kinetic model. Moreover, fourier transform infrared spectroscopy (FTIR) results demonstrated that functional groups such as amine (-NH2 (and hydroxyl (-OH) had the largest effect on zinc adsorption. Conclusion: According to the obtained results, the chitin extracted from crab shells appears to be a suitable adsorbent for the removal of zinc from aqueous solutions Manuscript profile -

Zinc is also an essential nutrient for plants, but excessive accumulation of zinc in plant tissues can alter plant growth stages. In such conditions, susceptible plants are damaged and killed while resistant plants continue to grow and reproduce in these conditions. The aim of this study was to investigate the effect of high concentrations of Pb and Zn on growth, amount of chlorophyll and carotenoid, accumulation and tolerance parameters of harmal. Material and Methodology: Harmal plants were treated with concentrations of 0, 5, 10, 25, 50, 100 and 200 mg/l for 14 days and concentrations of 0, 1, 5, 10, 20, 40 and 80 mg/l Zn. Findings: The results showed that increasing lead and zinc concentration decreased shoot length, root length, shoot dry weight and root but increased lead and zinc accumulation in shoot and root. Chlorophyll a, b, total and carotenoid contents also decreased significantly under different concentrations of Pb and Zn compared to the control. Discussion and Conclusion: Therefore, it can be concluded from this study that harmal has high ability to accumulate and tolerate lead and zinc and can be used for phytoremediation of lead and zinc.

It is a metaloenzyme containing copper ions that catalyses two distinct reactions in the pathway of melanin biosynthesis. The monophenolase activity leads to hydroxylation of phenylalanin and the oxidation of 3, 4 dihydroxy phenylalanin to O-dopaquinon is through its diphenolase activity. Inhibitors and activators of the enzyme has a wide variety of effects on human health as well as in industrial applications. Considering the importance of pigments in human skin and hair and the role of tyrosinase in the production of melanin pigments, in the present research three important skin medications were selected for their effect on tyrosinase activity. In practical section, the enzyme was first extracted from banana skin followed by its characterization. The kinetic parameters were then investigated in the presence and absence of benzocaein, zinc oxide and kojic acid and the Michaelis Menton as well as Linweaver Burk plots were obtained. The results indicated that tyrosinase extracted from banana skin is similar to mushroom tyrosinase and its optimum temperature is higher than known tyrosinases. Therefore, by bearing in mind its low priced source, it can be recommended as an alternative to the commercial enzyme from mushroom. The results also showed that all three medicines were un-competitive inhibitors of tyrosinase. They reduced the maximum rate, Vmax of enzymatic reaction with no effect on Km. The highest inhibitory activity was obtained for zinc oxide Keywords: Tyrosinase, banana wastes, benzocaein, kojic acid, zinc oxide Manuscript profile -

This rodenticide may be consumed deliberately, unintentionally, for suicide purposes, or other purposes. We report the case of a 38-year-old man, who committed suicide by consuming almost 100 grams of zinc phosphide rodenticide and experienced reduced consciousness and cyanosis. The early symptoms of cyanosis included nausea, vomiting, headache, vertigo, numbness, weakness, blurry vision, epigastric abdominal pain, and pain in the upper and right abdominal sections. The patient also had no history of diabetes mellitus, high blood cholesterol, hypertension, hepatitis, tuberculosis, minor thalassemia, and mental diseases. Zinc phosphide is a life-threatening poison with no specific antidote. Besides, phosphide poisoning including zinc phosphide poisoning must be considered in young patients suffering from sudden hypotension and metabolic acidosis, while abdominal radiography contributes to the early diagnosis of the disease.

Excessive use of chemical and industrial materials has created many problems for these sources. Therefore, providing new methods to remove water pollutants is very important. The method of green synthesis of nanoparticles has attracted a lot of attention due to its features such as greater safety, compatibility with the environment, simplicity, and low cost. In this research work, the green synthesis of zinc oxide nanoparticles was carried out using the Daphne macronata plant and it was used in the preparation of a cellulose acetate/zinc oxide filter. The electron microscope image of the nano filter shows that the average diameter of nanofibers is about 40 nanometers and the average size of nanoparticles is about 47 nanometers. Also, the effect of this filter in removing methyl orange dye from water sources was investigated in different conditions of dye concentration, amount of adsorbent, and pH. The results showed that the cellulose acetate/zinc oxide nanocomposite filter is able to remove about 90% of methyl orange color in optimal conditions. Also, the results of investigating the antimicrobial effect of this structure on 4 samples of pathogenic bacteria, including Bacillus cereus and Staphylococcus epidermis, Salmonella, and Acinetobacter were carried out. The results showed that the largest diameter of the halo of non-growth is related to the pathogenic bacteria Bacillus cereus and Staphylococcus epidermis and is about 22 mm Manuscript profile -

Some species of Enterobacter are described to be used in biofertilizers with direct and indirect plant growth promotion. This research aims to isolate phosphate solubilizing bacteria (PSB) and evaluate their effects on maize growth. So, rhizobacteria were isolated from the maize rhizosphere, and screening was performed on Sperber and Zinc oxide media. Other rhizobacterial traits such as ammonia and hydrogen cyanide production, nitrogen fixation, nitrate reduction, and the effect of environmental factors were also evaluated. Out of 42 PSB, 5 isolated strains with the best results were used for further tests and they were identified based on their 16S rRNA gene sequence as Enterobacter cloacae, Enterobacter hermoche, and Enterobacter sp. All selected strains were able to solubilize phosphate and zinc and could tolerate NaCl up to 7% and grow in pH 5 to 9, and finally, they could grow in temperatures in a range of 4 to 44oC. All 5 isolates could significantly increase shoot height and root length, and wet weight of shoot and root. Finally, according to the in-vitro and in-vivo results, the evaluated capabilities of bacterial strains isolated from maize are attractive and highlighted and it makes them good candidates for the construction of novel biofertilizers.

For this purpose, 120 samples of surface soil (0 to 10 cm depth) were taken at 24 and 96 dry farm and irrigated soils respectively. After determining the total concentration of the sample, 36 soil samples for chemical and physical analysis and sequential extraction were selected. According to the results, total Zn and DTPA-extractable for dry farm and irrigated soils were 142.8, 1.66 and 230.1, 15.30 mg/kg respectively. Not significantly different were found between the two soils and the chemical fractions in descending order were: soluble + exchangeable fraction < bound to carbonate > bound to organic matter > bound to iron and manganese oxides < residual. Although the contribution of each fraction in the two soils was different. The physical and chemical properties of soils, the greatest influence on the distribution of chemical organic matter fraction was found. The DTPA-extractable Zn was affected mostly by organic matter and pH. Because of the dynamic equilibrium is established between the different phases, so different fractions are correlated strongly. To determine risk assessment in Zn risk assessment code (RAC) was used for dry farm and irrigated soils with 4.1 and 5.5 percent respectively which fall into low risk limit. Manuscript profile -

MoreThis study reports the antibacterial capability of low-density polyethylene (LDPE) modified with ZnO nanoparticles using a Sol-Gel technique. Antibacterial activity of prepared films against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) was examined. The operational conditions such as pH, time, amount of ZnO nanoparticles, and silanol concentration were optimized using the response surface methodology (RSM). The proposed film under optimum conditions was applied for the packaging of the milk sample. The highest antibacterial activity of ZnO/LPDE were pH (6.0), time (103 min), amount of ZnO nanoparticles (0.68 % w/v) and silanol agent concentration (4.81 % v/v). The antibacterial properties of ZnO/LDPE films were assessed based on the diameter of the inhibition zone in a disk diffusion test against E. coli and S. aureus. These films have significantly reduced the growth of mentioned bacteria. Overall, antimicrobial packaging shows promise as an effective method to inhibit the growth of certain bacteria like E. coli and S. aureus in milk. The resulting ZnO/LDPE package films containing milk samples exhibit superior and prolonged antibacterial activity against E. coli and S. aureus in 7 and 14 days. Manuscript profile -

Disrupting the homeostasis of metal elements such as zinc in the central nervous system, stress causes diseases or dysfunction of various tissues. Zinc plays an important role in the function of vital organs, especially the central nervous system. Disorders of zinc homeostasis in turn lead to the development or progression of diseases such as Alzheimer's, depression, learning disabilities, and ischemia. Zinc transporters (ZnT) and ZIP proteins maintain Zinc homeostasis in the live organisms. The aim of this study was to investigate the effect of acute motor restraint stress on the expression of Znt1, Znt2, Znt3, and Znt4 genes in the hippocampus of rats as one of the tissues with high zinc density. Adult male rats were divided into groups of control and stress. RNA was extracted from hippocampal tissue and changes in the expression of Znt1, Znt2, Znt3 and Znt4 genes were monitored by real-time PCR. The results showed that due to stress induction, Znt1 gene expression increased significantly and no significant changes were observed in the expression of other studied genes. Identifying those zinc transporter genes that are altered by stress can make it possible to find a cure for stress by regulating zinc levels in the body through Zinc-containing drugs.

Foliar spraying of nitrogen, zinc and potassium fertilizers on corn plants can provide farmers and researchers with very good information about the effect of nitrogen, zinc and potassium fertilizer consumption in the climatic conditions of Golestan province.Aim: Considering the medicinal effects of corn cob and its importance in medicine and the presence of special effective substances in this connection in corn silk, it seems that their quantity and quality are affected by the use of nitrogen, zinc, and potassium. Therefore, examining these changes is one of the practical goals of this research.Materials and methods: In order to evaluate the changes resulted from nitrogen, zinc, potassium and their simultaneous application were done on some morphophysiological traits of single cross 704 hybrid maize as a randomized complete block design with four replications in spring and summer of 2019 in Golestan province, the Katoul farm. Treatments included nitrogen(N), potassium(P), zinc(Z) fertilizer and combined application of nitrogen+potassium(NP), nitrogen+zinc(NZ), potassium+zinc(PZ) and their combined application of nitrogen+potassium+zinc(NPZ) with control. The results showed the traits were affected by fertilizer sources significantly (p≤ 0.01).Results: The studied treatments had a significant effect on the traits of height to the first corn, number of rows, ear length and ear diameter at the time of full ripening at the probability level of (p≤ 0.01). With the application of zinc, nitrogen and potassium elements, a significant increase in the content of phenolic compounds of leaves, silk and corn seeds was observed. The flavonoids of leaves, silk and seeds were influenced by the supply of nitrogen (N), zinc (Zn), potassium (K) fertilizers and their simultaneous application. Leaf anthocyanin in foliar spraying treatments with single potassium fertilizer, due to creating optimal conditions, most of the current energy of the plant was spent in the direction of growth, development and increasing the yield of treated plants, so the biosynthesis and production of anthocyanin in corn leaves with single application of potassium was less, but silk anthocyanin And the seed with single application of potassium and simultaneous application of potassium+nitrogen, potassium+zinc, potassium+nitrogen+zinc showed a significant increase compared to the control. Conclusion: according to the obtained results, the simultaneous application of fertilizers is recommended to increase the morpho-physiological traits and yield of plants. Manuscript profile -

This cake contained 180080, 26840, 141040 and 254090 ppm of sulfur, nickel, cadmium and zinc, respectively. Zinc extraction was performed using Cyanex 272 organic solvent. The investigated variables included pH (in the range of 0 to 1.5), time (in the range of 1 to 6 hours), temperature (60 to 80 °C) and the ratio of solids to solution (10 to 30%). Experiments were designed in Design-Expert software version 7 and using central composite design (CCD). pH was the most influential parameter and temperature was the least important parameter. The highest efficiency was measured with 100% at pH 0, temperature 80°C, ratio of solids to solution 30% and time 6 hours. The lowest zinc removal efficiency with 76.6% occurred at pH 1.5, temperature 60 and ratio of solids to solution 10% and time 3.5 hours. Considering the average zinc removal efficiency of 89.10%, the combination of using Cyanex 272 solvent and pH is a suitable method for extracting zinc from cold cake waste and this method has a high performance.

Experimental factors consisted of water stress as the main factor with three levels (irrigation after70mm evaporation, irrigation after120mm evaporation and irrigation after 170mm evaporation from class A pan), Secondary factor consisted of: application of microelement with two levels (control and application of zinc sulfate 0.005 concentration) and ascorbic acid with four levels (not application, application of 50 mg/l of ascorbic acid, application of 100 mg/l of ascorbic acid and application of 150 mg/l of ascorbic acid). The results showed that the effect of water deficit on purple coneflower caused significant differences in diameter of stem, number of flowering branch, stomata density, zinc concentration of aerial parts plant, fresh weight, relative water content of leaf, LAI, proline concentration, crop growth rate, relative growth rate and net assimilation rate. Comparison of means for water deficits between the different levels of drought stress showed that the maximum LAI, with 2.85, belonged to control. Comparison of means for interaction effects between drought stress and application of zinc sulfate revealed that the maximum proline concentration belonged to spraying plants with zinc sulfate at irrigation after 170mm evaporation from class A pan with 10.16 mg/g.fw. Minimum proline concentration was due to without applying zinc sulfate in complete irrigation (control) with 0.08 mg/g.fw. Maximum crop growth rate with 6.77 g/m2.day was was related to control and the minimum, with 4.16 g/m2.day, to irrigation after 170mm. Maximum relative crop growth rate, with 0.19 g/m2.day, belonged to control and the minimum, with 0.14 g/m2.day, to irrigation after 170mm. Maximum net assimilation rate, with 2.64 g/m2.day, belonged to control and the minimum, with 1.91 g/m2.day, to irrigation after 170mm. The results indicated that application of ascorbic acid, as an antioxidant, may decrease the harmful effects of drought stress on some traits (NAR, CGR, RGR, and RWC) of purple coneflower.

Experimental treatments consisted of five levels of mixed culture of corn and beans (100% beans, 75% beans + 25% corn, 50% beans + 50% corn, 25% beans + 75% corn, and 100% corn) and four levels of iron and zinc nanoclates combination (iron nanoclate, zinc nano-chelate, iron nano-chelate + nano-chelate zinc and control). Number of seeds per ear row, 1000-seed weight, seed yield and harvest index were measured. The results showed that the effect of planting ratios on number of seeds per ear, 1000-seed weight and harvest index were statistically significant at 1% and on grain yield at 5% level of probability while it was not significant on number of seeds per ear row and number of rows per ear. The highest number of seeds per ear (707.8), seed yield (12787 kg.ha-1) and 1000-seed weight of corn (253 g) were obtained from 25% bean + 75% corn crop ratio. The highest harvest index (52%) was obtained from pure culture. Simultaneous application of nano-chelate iron and zinc increased the quantitative and qualitative properties of corn. Intercopping of 25% cowpea + 75% corn with nano-chelate application produced the highest proein percent (22.3 %). The highest value of land equality ratio (total) (2.12) was obtained by using a mixed cultivation treatment of 75% bean + 25% corn and the lowest (1.57) by 25% of beans were +75% of corn and zinc combinations. Finally, the highest grain yield of 12,993 kg.ha-1 was obtained from a intercropping of 75% corn + 25% bean and application of iron and zinc. Manuscript profile -

To evaluate the effect of zinc foliar application on yield and yield components of four wheat cultivars a factorial experiment with two factors was conducted in randomized complete blocks design with three replications in 2011-2012 year. The first factor consisted of four wheat cultivars (Falat, Bahar, Pishtaz and Tous) and the second factor composed of three levels of zinc chelate foliar applications (control, at shooting stage and at shooting + flowering stages). Zinc concentration in each application was decided to be 4 kilogram per hectare. Results showed that yield and yield components of cultivars were significantly different with each others. The highest and lowest yields were belonged to Bahar and Tous respectively. The highest yield of Bahar, as compared to the other cultivars, was due to its higher biological yield. Zinc foliar applications at shooting and shooting + flowering stages also increased biological and seed yields. Seed yield increase mainly affected by higher 1000 seed weight. In general, it seems that zinc application, due to its role in the physiology of wheat, a sensitive plant to zinc deficiency, may increase its seed yield. Manuscript profile -

The experiment included various irrigation regimes (control), (medium stress), (severe stress), four landraces (Fanuj, Khash, Saravan and Sarbaz), with and without foliar application of zinc oxide nano particles. The experiment was conducted in green house of the faculty of Agriculture, Tarbiat Modares University, during 2018-2019. The highest leaf area (538.92 cm2) was related to Sarbaz in control irrigation and the lowest leaf area (245.88 cm2) was related to Khash in severe water deficit stress. Based on the comparison results, the mean of maximum plant dry weight (1.76 g) was related to Sarbaz and control irrigation and the lowest plant dry weight (0.63 g) was related to Fanuj and severe water deficit stress. Also, the highest amount of chlorophyll a (2.55 μmol.g-1) was related to Khash, control irrigation and foliar application of zinc oxide nano particles. The highest amount of chlorophyll b (1.26 μmol.g-1) was related to Fanuj, control irrigation and foliar application of zinc oxide nano particles, which was not significantly different from other landraces. Also, the lowest amount of chlorophyll b (0.62 μmol.g-1) was related to Khash, severe water deficit stress and without foliar application of zinc oxide nano particles. Sarbaz had the highest amount of anthocyanin (0.3 μmol.g-1) in the treatment of severe water deficit stress and lack of foliar application of zinc oxide nano particles, which was not significantly different from Saravan. Also, the lowest amount of anthocyanin (0.146 μmol.g-1) was related to Fanuj in the treatment of severe water deficit stress with foliar application of zinc oxide nano particles. Severe water deficit stress reduced the amount of traits tested. Also, the Sarbaz showed good tolerance to water deficit stress conditions compared to other landraces. The foliar application of zinc oxide nano particles also improved plant growth and increased some of the tested traits under stress conditions. Manuscript profile -

To evaluate the effect of these micronutrients on the yield and some traits affecting potato tubers an experiment was conducted in a complete randomized block design with three replications in Ardabil during 2012. Micronutrient treatments used were the various concentrations of iron and zinc (0.002, 0.004 and 0.008 concentrations of these elements as Fe1Zn1, Fe1Zn2, Fe1Zn3, Fe2Zn1, Fe2Zn2, Fe2Zn3, Fe3Zn1 and Fe3Zn2) and a control treatment (Fe0Zn0). Analysis of variance of traits under study showed statistically significant differences among treatments in terms of tuber yield, number of tubers per plant, tuber size, skin thickness and volumetric weight and dry weight of tubers. The highest tuber yield (48.10 t.ha-1) and maximum skin thickness were obtained from Fe1Zn3 treatment. The highest tuber number belonged to Fe2Zn1 (0.004 and 0.002 concentrations of iron and zinc) and Fe1Zn3 (0.002 and 0.008 concentrations of iron and zinc). Tuber weights higher than 35 grams and higest volumetric tuber weight were produced by using Fe3Zn2. The conclusion is this that using Fe1Zn3 traetment (0.002 and 0.008 concentrations) resulted in highest tuber yield and thickness of tuber skin. Manuscript profile -

This study aims to evaluate the root and shoot structure of quinoa cultivars in response to the application of phosphorus and zinc in the Research, Agricultural Education and Natural Resources Center of Khuzestan province in a factorial design with three factors including the use of triple superphosphate fertilizer at four levels (0, 6, 12, 18 mg.kg-1 soil weight), foliar application of zinc sulfate in three amounts (water without zinc sulfate (control), foliar application at 4 and 8 per thousand concentrations) and three quinoa cultivars (Giza 1, Q26, Titicaca) were performed in pot and in three replications. The results showed that root parameters such as root dry weight, root width, root diameter, distance from the first branch to the tip root, and the weight ratio of root to shoot were affected by phosphorus fertilizer levels and quinoa cultivars (P≤0.01) and foliar application of zinc sulfate had a significant effect only on root dry weight, root width, distance from the first branch to the root tip, root density, root weight to shoot weight, and aerial part parameters. Q26 cultivar was identified as the best cultivar in terms of root structure development, which at 18 mg.kg-1 phosphorus levels and 4 per thousand zinc sulfate concentration had a maximum root dry weight (3.23 g.plant-1), root width (18.06 cm) and distance from the first branch to the root tip (53.23). At these levels of element consumption, the highest number of grains per plant (4542) were obtained in cultivar Q26. Based on the experiment results, the optimal level of elements by reducing antagonistic effects and increasing synergistic effects of P and ZnSO4 led to the root structure development, improved element uptake and increased production components of quinoa cultivars.

Results of ANOVA showed that there were highly significant differences between wheat and bean residues along with application zinc sulfate, protein, phytic acid in wheat grain, phytic acid to zinc molar ratio and yield. The results also showed that the highest grain yield, protein content and grain zinc concentrations were related to bean residues + application sulfate zinc treatment and the lowest yield to control. The use of crop residue on the soil caused a significant increase in grain yield and shoot, as compared with that of the control (p<0.01). The results also revealed that bean residue caused a 20% increase in grain yield. Application of plant residues, specially bean residues + applivation of zinc sulfate decreased the phytic acid to zinc molar ratio in all treatment in respect to control. Amongst the plant residues, bean residues, as compared with residues had the lowest effect of carbon to nitrogen ratio. The highest wheat grain yield related to the treatment of bean residues + sulfate zinc application. Based on the results of this research it can be concluded that application of bean residues + application sulfate zinc may produce highest grain yield and protein content while the lowest phytic acid to zinc ratio and grain yield from other treatments.

Due to the important nutritive role of wheat in these countries, researchers are trying to produce wheat grains with higher nutrients contents like iron, zinc, ascorbic acid and protein, along with low phytic acid content and Zn/PA ratio to limit malnutrition. Because of significant role of Zn on the metabolism of carbohydrates and proteins; the effects of foliar application of Zn on the quality and yield of wheat grains was studied. In this study six wheat cultivars were planted at a farm in Tastaghar village located in Hashtrood county, during early fall of 2016 in split plot experiment based on randomized complete block design. Treatments used were six wheat cultivars (Baran, Tak-Ab, Sardari, Ohadi, Homa and Azar 2) and leaf foliar application of Zn with four levels (control, during beginning of stem elongation and stem elongation+anthesis stages). Zn foliar treatments were applied in the evenings by a portable pump sprayer. The results revealed that the foliar application of Zn increased seed yields of the cultivars under study. Moreover, protein, Zn and ascorbic acid content of the seed were also increased significantly (P≤%5). However, phytic acid content and Zn/PA ratio were decreased as compared to control. Overall it can be said that, foliar application of Zn had positive impact on the seed yield, proteins, Zn and ascorbic acid contents. It can be concluded that the foliar application of Zn on wheat would improve the seed yield and some qualities of wheat cultivars. It would be advisable to extend continuing this kind of studies to overcome malnutrition problems of area. Further studis is recommended to substantiate the results. Manuscript profile -

In this experiment, winter plantings with three levels (24th February, 6th, and 16th March) and Zinc factors with two levels, including application of zinc sulfate spray and spray with pure water assigned to main plots and spring cultivars, including RGS003, Zafar, Julius, Jerry, Zabol 10, Hyola 4815 to subplots. The results of combined analyses of data showed that the effect of year, planting date, zinc spray, cultivar and planting date × cultivar interaction effects on qualitative traits (grain glycosinolate content and fatty acid percentages) in different planting dates and cultivars were significant at 1% level of probabilities. According to the results, the highest (66.89%) and lowest (66.02%) oleic acid percentages belonged to zafar and zabol10 cultivars, respectively. Planting dates × cultivar interaction effect on the glucosinolate content indicated that the lowest glucosinolate content produced by Zafar (8.313 mg.g-1) and hyola4815 (8.567 mg.g-1), when they were sown on March 16th. The results of this experiment showed that delayed planting, decreased percentages of palmitic, linoleic and oleic acids of seed oil, while increased percentages of linolenic and erousic acids and glycosinolate contents.

Accordingly, the effect of different levels of zinc and nitrogen on leaf area index, yield and yield components of green beans investigated in the summer of 2012. The experiment used was a split plot in randomized complete block design with three replications in the Dezful. In this study, the main plots consisted of four nitrogen rates of urea (0, 30, 60 and 90 kgha-1), and sub plots of four levels of zinc sulfate (0, 10, 20 and 30 kg.ha-1). The results showed that application of 90 N kg.ha-1 increased leaf area index, plant dry matter, grain yield, biological yield, harvest index and protein content. Use of zinc sulfate at the rate of 20 kg.ha-1 was superior in grain yield and yield components. The highest leaf area index, grain and biological yields harvest index and protein content were achieved by application of 90 kg nitrogen and 20 kg of zinc sulfate per hectare. It seems that the use of zinc with appropriate rates, through its involvement in physiological processes and nitrogen metabolism in plants as an essential element, accelerates green beans growth processes and increases green bean yield.

The first factor consisted of four durum wheat genotypes and the second factor of levels two zinc sulfate application (control and foliar application of Zn on soil at stem elongation + seed filling stages). The results showed that application of zinc sulfate could increase biological and seed yields of RCOL genotype by 2 and 4 times compared to control respectively. The effects application of zinc sulfate on biological and seed yields of other genotypes were not significant. Based on the results obtained from this study the highest increase in seed weight was 20.7% in the RCOL genotype by Zn application. The highest reduction in phytic acid to zinc molar ratio was observed in Ege-88 genotype and this ratio was decreased by 52.2 percent in the control to 8.4% due to Zn application. This may indicate different responses of durum wheat genotypes to the zinc deficiency in the soil. The results also showed that the number of seed per spike was increased by 22.7 percent and phytic acid was decreased by 62.3 percent due to the application of zinc sulfate. Also, application of zinc sulfate increased Zn concentration in seed from 29.9 mg.kg-1 to 64.7 mg.kg-1 in control. In general, however, the application of zinc was not the reason of seed yield improvement of all genotypes studied but it improved seed yield qualities. It can be concluded that use of Zn is an appropriate method to improve the qualitative and quantitative traits of seed yield. To confirm these results other studies are needed. Manuscript profile -

The development of nanotechnology over the past decades has opened up opportunities for discovering the antibacterial effects of metallic nanoparticles. In this study, the antibacterial properties of nanoparticles on aluminate (ZnAl2O4) were studied on Escherichia coli and Pseudomonas aeruginosa bacteria. Antibacterial activity was assessed by using the disk diffusion method on agar using nanoparticles on synthesized aluminate. The non-growth halo diameter indicates the sensitivity of bacteria to antimicrobials. The minimum inhibitory concentration of bacterial growth (MIC) and minimum bacterial leaching concentration (MBC) was measured by microdilution in sterile tubes. Statistical analysis was done by T-test. The results of this study showed that Pseudomonas aeruginosa sensitivity (16.06±1.8mm) was higher than E. coli (11.64±2.2mm) (p < 0.05). The minimum inhibitory concentration (MIC) and bactericidal concentration MBC of bacteria Pseudomonas aeruginosa and Escherichia coli bacteria MIC and MBC was lacking. According to the results obtained in this study, we conclude that Pseudomonas aeruginosa was more sensitive to alumina than that of E. coli against nanoparticles. Manuscript profile -

In this study, the effect of coating combination of gelatin and Opopanax mucilage containing 0.5% zinc oxide nanoparticles, enriched by concentrations of 0, 1.2, 1.6, and 2.0 % of peppermint essential oil and modified atmospheric packaging (MAP) on preventing the growth of microbial population rainbow trout fillets were evaluated during 20 days of storage in the refrigerator. The results showed that in all treatments the number of aerobic mesophilic bacteria, psychrotrophs, lactic acid bacteria, and coliforms as well as pH increased during the storage period but decreased by increasing peppermint essential oil (p<0.05). Also, the microbial load in treatments with a coating containing nanoparticles and MAP was significantly lower than in the control sample (p<0.05). The results of sensory evaluation also showed that the odor and color scores of the samples decreased during storage, which was the highest in the control and the lowest in the NPEO3 treatment (p<0.05). The results of the sensory evaluation were consistent with the results of microbial analysis. According to the results obtained in this study, using the mixture of 0.5 % zinc oxide nanoparticles and 50% peppermint essential oil in edible coating composed of Opopanax mucilage and gelatin for increasing the shelf life of rainbow trout fillet up to the 15th day is recommended.

Soil contamination with heavy metals occurs as a result of human activities. Heavy metals can easily accumulate in edible tissues of leafy vegetables, fruits and seeds. Few studies have been conducted on heavy metals concentration in soil and greenhouse crops. Therefore, this study aimed to determine the concentrations of lead (Pb) and zinc (Zn) in greenhouse cucumbers produced in Hamadan province. The concentrations of heavy metals were measured using atomic emission method. Results showed that the mean concentrations of Pb and Zn in cucumber samples were 0.33 and 3.14 mg/kg, respectively. Also the results of the statistical analysis revealed a negative correlation between the measured concentrations. Moreover, the concentration of Zn in the samples obtained from Hamadan greenhouses and lead concentration in Tuyserkan, Famenin, as well as Malayer samples were above the recommended limits. Daily intake amounts of Pb and Zn from vegetables consumption for three age categories (children, adolescents, and adults) were calculated. In conclusion, daily intake of Pb and Zn were determined below the recommended limits. Manuscript profile -

The aim of this study was to investigate pathological alterations of gill tissue in common carp during exposure to different nanoparticles. For this study, 210 fry common carp with a total length of 7.36±0.30 cm and goldfish with a total length of 6.50±0.43 cm in 6 treatments with 3 replicates in each treatment were placed in 60 liter aquariums in groups of 11 individuals. Gill tissue samples of common carp and goldfish were taken 7 days after exposure to 50% lethal concentration of nano-zinc oxide, nano copper oxide and titanium dioxide nanoparticles. Histological changes were evident in samples exposed to nano-zinc oxide, nano copper oxide and titanium dioxide nanoparticles while no detectable changes were observed in control gill. The symptoms observed in both fish consisted of gill hyperplasia, adhesion of secondary lamellae, increased levels of mucus and hyperemia. The most common complication observed was gill hyperplasia and an increase in the amount of mucus. The results of this study indicate that 50% lethal concentration of nanoparticles of titanium, copper and zinc can cause tissue damage and destruction. Also, sub-lethal toxicity of nano-zinc oxide is higher than nano copper oxide and nano titanium dioxide and causes much wider effects on gill tissue of common carp and goldfish. Manuscript profile -

In this study, blood samples were taken from cows suspected of deficiency including animals that had anorexia, decrease in production and most importantly infertility problems. Samples were also taken from the animals diets. Sampling was conducted on a seasonal basis and 25 serum samples were collected in each season. Measurement was performed using atomic absorption method and serumic levels were calculated in micromoles. The results of this study indicated that in the animals suspected of zinc deficiency, there was no significant difference between different seasons but zinc levels were below normal in winter, spring and autumn. It is probable that dietary zinc deficiency especially low zinc levels in concentrate diets in the main cause of low zinc values in this study. Manuscript profile -

Special biochemical kits were used for determination of zinc, copper, albumin, calcium, magnesium and ferrous levels in sera. Serum levels of transferin and ceruloplasmin were measured with ELISA and Sunderman & Nomoto method, respectively. The serum level of zinc was significantly decreased in cattle suffering from theileriosis (p<0.01). Serum concentration of copper showed decrease in cattle with theileriosis but it was not significant. The Biochemical findings revealed that cattle infected with theileriosis have significantly lower serum levels of transferin, magnesium, albumin, iron (p<0.01) and calcium (p<0.05). Serum value of ceruloplasmin in sick animals was significantly more than healthy cattle (p<0.05). There was significant relationship between serum level of zinc and ceruloplasmin with PCV and also between serum iron level and parasitemia (p<0.05). Results obtained from measurement of biochemical parameters in serum suggested that reduction of serum zinc and copper may be one of the possible reasons of immunosuppression and incidence of secondary infections in cattle with theileriosis. Therefore use of these trace elements, especially zinc in treatment protocol of infected cattle may be beneficial. Manuscript profile -

In order to investigate the effect of zinc and gibberellin on the biochemical and physiological characteristics of white beans (Phaseolus vulgaris L.) in drought stress conditions, an experiment in the form of double-plotted plot with a randomized complete block with three replications in two locations (Islamabad West Research Station). Kermanshah province, and Khorramabad research station in Lorestan province. Experimental factors include irrigation at 3 levels of 60, 90 and 120 mm evaporation from Class A evaporation pan as the main plot, zinc sulfate solution at 4 levels 0, 1.5, 3.5 and 4.5 ml/liter and 2 levels Gibberellin spraying and spraying were used as sub-plots. Data analysis and comparison of average data by Duncan's method was performed at 5% level by SPSS software. The results showed that the main effect of drought stress and zinc sulfate foliar application was significant on all traits, and the main effect of gibberellin foliar application on all traits was significant except for yield and transpiration rate. The interaction of zinc sulfate, stress and gibberellin had all significant properties. The highest grain yield was related to normal irrigation treatment and consumption of 4.5 ml/l of zinc at, which differed from the treatment of moderate stress and consumption of 1.5 ml/l of zinc and the use of gibberellin. It did not make much sense. The lowest grain yield in the severe stress treatment and the use of 3.5 milliliters per liter on the gibberellin spray solution. In general, seed yield increased both in drought stress and non-stress conditions, so according to the results, it is recommended to consume 4.5 ml/l of zinc sulfate and Gibberellin foliar application to reduce the effects of drought stress on bean cultivation.

In this research, effects of four levels of Nitrogen sources (100 % urea, nano-chelate nitrogen, 100% Panaromix biologic fertilizer, and 50% urea + 50 % Panaromix biologic fertilizer) along with three levels of Zinc sources (control or without application of Zn, zinc sulfate, and nano-chelate zinc) and interaction effects of hese sources were investigated on physiology and yield of wheat. The study was carried out by split-plot method based on completely randomized blocks design with 3 replications and 12 treatments in a private farm located in the north of Jelin, a city located 3 Km east of Gorgan, during the 2017-2018 crop year. Results showed that the traits under study were affected by the sources of nitrogen supply and the interaction effects of sources of the two elements but there was no significant difference under treatment with sources of zinc supply. In Nitrogen supply sources, the maximum leaf area and number, shoot length, chlorophyll b and chlorophyll (a+b) content, and nitrate reductase activity as well as biological and grain yield was related to 100% urea and 50% urea + 50% biologic fertilizer. In combined treatments with the interaction effects, the highest amount of proline was related to 100% biological fertilizer + nano-chelate zinc and in the treatments that were associated with increased proline, there was no increase in the soluble sugars and glycine betaine contents. The highest level of NR activity, chlorophyll a, and total chlorophyll (a+b) content, and also the highest level of grain performance and biological yield were observed in 100% urea + Zinc sulfate fertilizer treatment. The results showed that high yield of wheat in this treatment was a function of plant physiological behavior, showing a positive interaction between nitrogen and zinc. Manuscript profile -

In order to investigate the effect of different levels of sulfur fertilizer (S) and foliar application of zinc (Zn) on the yield and concentration of oil and protein, a factorial experiment was conducted in a randomized complete block design with three replications for two year (2019 and 2020) at Astana-Ashrafieh city, Gilan province. The studied factors were included S fertilizer (from gypsum source) at four levels (0, 20, 40 and 60 kg ha-1) and Zn fertilizer (from zinc chelate source) at three levels (0, 1000 and 2000 ppm). The results showed that the interaction of S and Zn fertilizers had a significant effect on pod yield, grain yield, number of grains and pods, protein and oil concentration. Mean comparison of the studied traits also showed the highest pod yield (156 g plant-1) in the treatment of 40 kg S + 1000 ppm Zn, while the highest grain yield (92.3 g plant-1) in the treatment of 60 kg S + 2000 ppm Zn was obtained. The highest weight of 100 grains (1283.6 g) belonged to the treatment of non-using of S + 1000 ppm Zn. The highest protein concentration (17.94%) was observed from treatment of non-using of S + 2000 ppm Zn, and oil concentration (46.09%) in sulfur fertilizer treatment of 60 kg S + 1000 ppm Zn. Based on the results of this experiment, it can be stated that the simultaneous application of sulfur fertilizer and zinc foliar application significantly increases grain yield and improves yield-related traits in the peanut and it can be recommended for the climatic conditions of Gilan.

The aim of this study was to synthesize ZnO nanoparticles and investigate their antibacterial effects on multidrug resistant (MDR) uropathogenic bacteria. ZnO nanoparticles were constructed by wet chemical method with inhibitor. Structural and optical evaluation of zinc oxide nanoparticles was performed by Ultraviolet absorption spectroscopy, X-ray diffraction (XRD), and Tunneling microscopy. Uropathogenic bacteria were isolated from the patient’s pediatric urine and identified through biochemical testing. Antibiotic resistance pattern of the isolates was determined by disk diffusion method and the antibacterial activity of ZnO nanoparticles was detected by pour plate method at the concentrations of 0.0125, 0.025, 0.05, 0.1, 0.2, 0.4, and 0.8 g/l. The produced ZnO nanoparticles had a hexagonal shape with the crystal size of 15 nm and an optical size of 3 nm. The minimum effective concentration of these nanoparticles that inhibited the bacterial growth was 0.05 g/l. E.coli was generally found to be the most frequent cause of UTI in children in Isfahan, in the center of iran, with the mean prevalence of 64%. Most cases of resistance were related to Ampicillin, Amoxicillin, Tetracycline and the highest sensitivity was related to Chloramphenicol, Gentamicin, Trimethoprim/Sulfamethoxazol. The results of the present study, in accordance to the previously approved safe characteristics of ZnO nanoparticles, concentration of 0.05 g/l is proposed to be evaluated for in vivo usage for treatment of urinary tract infections.

Hetero-photocatalytic methods which utilized semiconductors as photocatalysts are highly promising and green technologies for the degradation of recalcitrant organic pollutants which cannot be completely removed by conventional treatment processes. In the view of the current scenario, zinc oxide nanostructures have been demonstrated to be predominant photocatalyst candidates for photodegradation because of their cost-effectiveness, non-toxicity, strong oxidation capability, flexibility in synthesizing, earth-abundance nature, easy crystallization, and high performance in the absorption over an extensive fraction of solar spectrum in comparison with titanium dioxide. Nevertheless, bare zinc oxide possesses several intrinsic limitations, like high recombination rate of the photogenerated charge carriers, limited solar light application, photo corrosion, broad bandgap and limited visible light absorption. Moreover, photocatalysts separation from remediated solutions restricts their large-scale applications. In this review paper, the authors briefly discussed basic principles of the zinc oxide photocatalytic process besides various modifications such as coupling with low bandgap semiconductors like metal and non-metal doping, synthesizing with graphene oxide, or reduced graphene oxide and their integration in magnetic materials to successfully addressing aforesaid disconcerting challenges. Moreover, hybridized photocatalytic and membrane systems are explored. Finally, challenges and future research directions are proposed for giving profound and well-defined insights toward reaching fully exploited zinc oxide-based nanoparticles in the field of water and wastewater treatments.

Commercial coating materials which are used for coating are non-edible as a result they are undesirable due to environmental pollution and allergies caused in some consumers. Today, biodegradable films are receiving more attention. In this study, the effect of edible coating of basil seed mucilage containing zinc oxide nanoparticles (ZnO-NP) in three levels of zero, 0.25 and 0.5% on the quality properties of cheddar cheese was investigated during ripening for 90 days. The results of experiments showed that at the end of ripening, the highest amount of salt and fat and the lowest amount of moisture were related to the sample with mucilage coating containing 0.5% of ZnO-NP. Also, during ripening, in all samples the number of non-starter lactic acid bacteria increased, but the number of starter bacteria increased first and then decreased (p < 0.01). Also, in all treatments, the total number of mesophilic aerobic bacteria, Pseudomonas, mold and yeast increased significantly during storage, which was the lowest in samples with coating containing ZnO-NP (p < 0.01). In addition, ZnO-NP coatings prevented mold growth on the surface of cheddar cheese samples. According to the results obtained of this study, basil seed mucilage containing 0.5% ZnO-NP can be used as a coating in cheddar cheese without any adverse effect on the flavor of cheese.

From the time of green revolution to till date high yielding and fertilizer responsive varieties have evolved to increase the production per unit area. To improve the productivity only major nutrients are concentrated almost in all crops. Though the importance of micronutrient realized during past decades in most of the crops but it is not effectively materialized in general crop cultivation practices. The micronutrient deficiencies in soil are not only hamper crop productivity but also deteriorating the produce quality. World health organization (WHO) has estimated that over 3 billion people in the globe suffer from the micronutrient malnutrition and about 2 billion people of these have iron deficiency. Iron is one of the 16 essential elements needed for plant growth. Iron is used for the synthesis of chlorophyll and is essential for the function of chloroplasts. Zinc is involved in membrane integrity, enzyme activation, and gene expression. Rice, sorghum and corn are Zn sensitive and sorghum, sugarcane, groundnut, soyabean, beans, grapes, vegetables and citrus are highly Fe sensitive crops. To overcome these problems foliar spray is being recommended but it is not crop specific or soil specific recommendation. Keeping these problems in the view, recently development of micronutrient efficient genotypes, creating awareness of micronutrient dose, crop specific micronutrient uptake and accumulation are vital to improve productivity and to address human health problems. In this paper we discussed the importance of iron and zinc in agriculture and their role in crop plants and ways to improve the crop productivity as well as human health. Manuscript profile -

The present study investigates the anatomical and morphological parameters like shoot and petiole length, total leaf area and leaf numbers response of Capsicum annum L. under different concentrations (0 (control), 2.5, 5, 7.5, 10 and 15 mM) of zinc. Plants were grown in greenhouse under controlled conditions. Results indicated that increasing zinc concentrations caused significant decrease in stem and petiole length, leaf area and number of leaves (morphological parameters) compared to control plants (P ≤0.05). Also in anatomical studies we noticed several changes in cross section of leaf, stem and root. Certainly, zinc at high levels showed a negative effect on the overall growth of bell pepper plants.

Due to their small size and easy absorption, nanoparticles can be a suitable option for treatment. In this study, a comparative study of the anticancer effect of silver nanoparticles, zinc oxide and iron oxide on leukemic cell line and white blood cells of HPB-ALL was done.Human white blood cells and leukemia cell line HPB-ALL were passaged. Iron oxide, zinc oxide and silver nanoparticles with different concentrations were added to the microplates containing the cells and the cells were treated with nanoparticles for 24 hours. PI was evaluated. The results obtained for leukemic cell line HPB-ALL and white blood cells were analyzed with the effect of three nanoparticles of silver, zinc oxide and iron oxide at a significant level (P<0.05). All three nanoparticles showed cytotoxic effects in both cell lines. The cytotoxicity effects of nanoparticles were higher in leukemic cell line HPB-ALL than in white blood cells. Among these nanoparticles, silver nanoparticles had a significant cytotoxic effect in HPB-ALL leukemic cell line compared to the other two nanoparticles. Evaluation of IC50, DNA damage and apoptosis induction in HPB-All leukemic cell line by silver nanoparticles was significantly higher than other two nanoparticles. According to the above results and further investigations of the penetration mechanism of each of the nanoparticles, it can be said that silver nanoparticles have the potential for therapeutic applications.

If aniline is swallowed or its vapor is inhaled, it will lead to death. Considering aniline risks on the environment and human health, it is necessary to prevent its spread into the environment. This study’s purpose is to remove aniline using a photocatalytic process under visible light irradiation. For this purpose, the zinc oxide was loaded with different values of reduced graphene oxide and graphene. The photocatalytic activity of modified zinc oxides (rGO/ZnO and G/ZnO) was investigated for aniline contaminant removal under visible light radiation. The physicochemical properties of zinc oxide and modified zinc oxides were analyzed by XRD, SEM, IR, PL, TEM and UV–vis (DRS mode) spectroscopy. The results showed that rGO/ZnO and G/ZnO composites had higher photocatalytic activity than ZnO, and the G(10%wt)/ZnO photocatalyst showed the highest photocatalytic activity and efficiency in removing aniline contaminant (75%).

Zinc oxide nanoparticles were synthesized by hydrothermal method via chemical reduction process. This method was performed using zinc acetate salt as a metal precursor, soda as reductant and water as a solvent for 1 hour at a temperature of 80°C. The samples were characterized by X-ray diffraction (XRD) to evaluate the crystal structure, and field emission scanning electron microscope (FESEM) to check the size of the particles and morphology of the samples. The mechanical properties of the samples were investigated. The obtained results showed that the moisture content in the optimal film was reduced to 1.01 x 10-8 g/m3 and the tensile strength and Young's modulus were increased to 0.492 MPa and 24.1 Pa, respectively. The antibacterial activity against Escherichia coli was evaluated by the agar well method and the final nanocomposite showed the highest antibacterial property with the non-growth halo of 0.64 mm. Cytotoxicity of the samples was recorded using the MTT assay method on the HEK293 cell line after 1, 3, and 5 days. The highest percentage of normal cell viability was observed at the concentration of 0.25 mg/ml of the sample and the final nanocomposite showed the highest cell viability. Based on the obtained results, nanocomposite containing zinc oxide nanoparticles and montmorillonite can have a good potential for use in food packaging industries. Manuscript profile -

Copper and zinc oxides were coated by synthesized compounds and were tested for antibacterial activity. All compounds were identified by NMR and FTIR spectra, X-ray diffraction (XRD), and elemental analysis. Scanning Electron Microscope SEM was used for the morphology of micro metal oxides before and after coating with Sulfonamide-Schiff bases compounds. Accordingly, antibacterial activity of compounds against Gram-positive bacteria (Staphylococcus epidermidis and Staphylococcus saprophyticus) and Gram-negative bacteria (Proteus mirabilis) were tested. It should be noted that both have high antimicrobial activities. The result of the study shows that the antibacterial activities of the synthesized sulfonamide-schiff bases against gram positive and gram negative bacteria decrease after coating on micro metal oxides. It is also worth mentioning that Ampicilin and Penicilin have been utilized as two standard medicines for investigating the antibacterial activities. Manuscript profile -

This study aims to elucidate the toxic impact of zinc on the structure of gill and liver in silver carp (Hypophthalmichthys molitrix). This study was conducted at spring 1390 at the International Sturgeon Research Institute. In this study, after adaptation, 135 fish with the length of 13±1 cm and the weight of 50±10gr were put in one control group and 2 treatment groups contained 0, 5, and 10mg/L (Zn (NO) 3)2 in 90 liter aquariums. Fish were sampled at 12, 24, 48, 72 and 96 hours. The samples of gill and liver in each treatment were immediately fixed in Bouin solution and 5μ sections were stained by Hematoxylin-Eosin general staining method. In histological study of gills, epithelial cell hyperplasia was encountered, that had increased with high metal densities. Initially lamella cells wrinkled and change of formation was observed in chloride cells. This lesion enhanced in higher densities. Fish liver exposed to zinc showed atrophy,cloudiness, swelling, hyperemia, vacuolation and necrosis. These hepatic alterations were more evident in fish exposed to high metal densities. In conclusion, the present study showed that histopathology of liver and gill in silver carp, is a useful biomarker for environmental pollution, since it discriminated between reference and test sites.

Microorganisms perform several mechanisms to reduce the intracellular concentration of toxic pollutants. The objective of this study was to identify zinc resistance determinant (czcC gene) in zinc resistant Pseudomonas stutzeri SEE-1 isolated from soil. Materials & Methods: The strain was performed on a P. stutzeri strain isolated previously from soil by culture on MTBE (Methyl Tertiary Butyl Ether). The maximum tolerable concentrations of zinc ions and zinc oxide nanoparticles were determined. PCR amplification was used to investigate the czcC gene. The nucleotide sequence was translated into protein sequence and its sequence was compared with other similar sequences in other zinc resistant bacteria. Results: The highest tolerable concentrations of zinc ion and zinc nanooxide was measured at 4mM and 600 µg ml-1, respectively. The primers used for the amplification of the Zn-resistance gene (czcC) yielded a approximately 250 bp band. The comparison of czcC with other sequences in the gene bank database demonstrated 100% similarities with czcC gene in P. stutzeri 1501. Conclusion: The results of this study showed that soils contaminated with heavy metals are potential sources for the isolation of resistant strains to heavy metals and metal oxide nanoparticles. Understanding the genetic basis of bacterial resistance to heavy metals can improve application of these natural mechanisms to provide a safer environment for all living things. Manuscript profile -

To investigate the effect of irrigation interval and foliar application of micronutrients on Panicum miliaceum, an experiment was conducted as split plot arrangement based on randomized complete block design with three replications in Sarbisheh agricultural research farm in 2012. Treatments including irrigation interval (7, 14 and 21 days) and foliar application of micronutrients in four levels (foliar application of manganese, zinc, zinc manganese and without foliar application) were assigned to main plot and sub plot, respectively. By decreasing irrigation interval to 7 days, the grain yield was increased mainly through increasing the number of grains per panicle (28% towards 21 day irrigation interval) and increasing the number of panicles per plant (25/68% towards 21 day irrigation interval). The foliar application of micronutrients improved the grain yield through enhancing grain number per panicle (23/29% towards treatment without foliar application) and enhancing panicle number per plant (15/17% towards treatment without foliar application). Findings showed that decreasing irrigation interval to 7 days and foliar application of micronutrients increased the yield and yield components of Panicum miliaceum. The maximum grain yield (222/6 grams per square meter) was under 7 day irrigation conditions and foliar application of manganese and zinc. Manuscript profile -

Therefore, easy, effective, economical and environmentally friendly techniques for treatments are needed. Use of organic absorbents is one of the newest and most appropriate cost techniques. In this study, soil was treated with citrus peel as low cost organic immobilizers in order to investigate the time effect on decreasing mobility of Ni and Zn. The soil was artificially contaminated with Ni and Zn in separate containers. Both elements were incorporated at a dose of 600 mg l-1 and then citrus peel was added to soils at the rate of 5%. Sampling of treatments was in 1h, 1, 3, 7, 14, 21, 28 days of incubation. The experiment was done with 2 treatments including polluted soil samples with and without citrus peel as control in completely randomized design. Statistical analysis done using the SAS software (version 9.1) and Duncan test was performed at 5% level. Results indicated that at the first time of incubation, the pH of soils decreased due to the presence of citrus peel and increased the availability of metals. But the prolonged incubation time led to increasing metal adsorption onto organic adsorbent surfaces and decreasing the metal concentration in exchangeable fraction. Mean Zn concentrations in the control soil and soil treated with citrus peel, were 107.8 and 98.3 mg kg-1 and mean Ni concentrations were 144.5 and 134.4 mg kg,-1 respectively. Differences in control and the citrus peel treatment for both elements were significant. Manuscript profile -

Therefore, to see how restricted irrigation systems and different potassium and zinc fertilizer affect water use efficiency and yield of corn, an experiment was conducted in an arid area in Marvdasht, Iran in 2012. A split-Factorial experimental design was used based on a complete randomized block design with three replications. The main plots consisted of two irrigation methods: FI (full irrigation) and partial rootzoon drying (PRD). Each subplot received three rates of K fertilizer application: 0, 2.5 or 5 kg ha-1 and three rates of Zn fertilizer application: 0, 2.5 or 5 kg ha-1 .The results showed that the plots receiving the full irrigation resulted in significantly higher grain yields, 1000-kernel weight and grain number per cob than PRD treatment. However, the highest WUE and IWUE were obtained in PRD, 5 kg K ha-1 and 5 kg ZN ha-1 and the lowest one was found in the FI treatment .In general, PRD irrigation method at high level of potassium and zinc fertilizer improved WUE and decreased WU in corn to 40% in an arid region.

This phenomenon can severely decreases corn yield. Although most researchers, mention that this phenomenon is the result of moisture and heat stresses at the time of pollination, but some other researches believed that it is due to the nutritional factors, especially Boron and Zinc nutritional elements. In order to examine the effect of zinc and boron application on corn grain production, an experiment was conducted at Gharakhil Agricultural research station in Ghaemshahr during the 2003-2006. The experiment was factorial and conducted in the field as a Randomized Complete Block Design, with 20 treatments, and 3 replications. The treatments were composed of five level of zinc (O, 8, 16 and 24 kg.ha-1 in soil and foliar application of ZnSO4 with 0.5 percent concentration) and four levels of Boron (0, 20 and 40 kg.ha-1 of boric acid in soil and foliar application of boric acid with 0.3 percent concentration), and finally their means were compared. The result from Mazandaran experiment, showed that application of Zinc caused a significant increased in grain yield ( = 5%), but application of Boron individually or Zinc in combination with Boron, had not significant effect on grain yield. The maximum grain yield (10380 kg.ha-1) was obtained due to application of 120 kg. ha-1 ZnS04 and 40 kg. ha-1 Boric Acid, which produced more yield (1415 kg. ha-1). The application of Zinc individually had only a significant effect on the length of corn ear and plant height, but application of Zn + Born had significant effect on length and diameter of corn ear percent of partly grain free and their effect on other studied parameters were not significant.

After preparing the alloy by the milling process, hardening is conducted during the sintering process. The condition for obtaining high strength and corrosion resistance of as-sintered specimens is the uniform distribution of zinc and manganese elements in the magnesium matrix and the maximum particle size reduction to increase the surface area. In this research, under certain conditions, the milling process has been conducted to fabricate this nanocomposite. The result of XRD analysis exhibited that the optimal sample is obtained after 25 h milling. At this time, the grain size was 27 μm, and the crystallite size was 24 nm. Evaluation of X-ray diffraction (XRD), X-ray fluorescence (XRF), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM), scanning electron microscopy (SEM), and field emission scanning electron microscopy (FE-SEM) results for samples shows uniform distribution of zinc and manganese particles in the matrix of magnesium and confirms the reduction of particle size with spherical shape for nanobiocomposite specimens.

Redistribution of Fe and Zn cations in tetrahedral and octahedral locations can significantly alter and increase saturation magnetization. The saturation magnetization of the synthesized ferrite nanoparticles was 57% higher than that of iron ferrite, and the nanoparticles had an average size of 35 nm. The synthesized nanoparticles were then functionalized using oleic acid and polyethylene glycol and three types of stable fluids based on water, engine oil and ethylene glycol were prepared. Optimal Ferro-fluid with the highest stability properties and amount of saturated magnetization was used to investigate the rheological properties. The non-Newtonian behavior of the fluid with different percentages of nanoparticles was investigated and the greatest change in behavior from the Newtonian state was related to the fluid with 15% by volume of nanoparticles.

Zinc de MoreZinc ion is the second essential element in living organisms and is necessary for lots of enzymes activity e.g. alkaline phosphatase and lactate dehydrogenase. This ion also takes part in biological processes as human growth, immune response, and nerve function. Zinc deficiency causes significant decrease in serum alkaline phosphatase or increase in aspartate aminotransferase and alanine aminotransferase activity. Increase in these two later enzymes, in turn, is an indicator of tissue damage even though there are controversies among researchers. Accordingly, we decided to study the effect of 0.6 gm/L of zinc sulfate in drinking water in a period of 3 months treatment on serum activities of hepatic enzymes in adult rats. Twenty female rats were selected in two equal groups as control and treated groups. For a period of three months, zinc sulfate dissolved in tap water was used to drink by the treated group while the control group drank tap water. Both groups had full access to pellet food during this study. Serum activities of aspartate aminotransferase, alanine aminotransferase, alkaline phosphates and lactate dehydrogenase were measured finally. Zinc sulfate significantly decreased alanine aminotransferase while it showed no effects on the three other enzymes. Dietary zinc sulfate not only exerts no damage to liver but also as food supplement seems to have protective effect on this organ. Manuscript profile -

After homogenization of the brain tissue, the activity of oxidative stress enzymes such as superoxide dismutase (SOD), glutathione-S transferase (GST), catalase (CAT), glutathione (GSH) and malondialdehyde (MDA) was determined using biochemical methods. The SOD, CAT and GST activities were significantly increased by exposure to 0.1 mg/ml zinc nanoparticles compared with other concentrations in brain tissue of roach (P<0.05). However, the amount of glutathione decreased with increasing exposure dose. In amount of malondialdehyde dose-dependent manner was observed, since the maximum concentration was recorded at 0.1 mg/ml of nanoparticles (4.5 ± 5.3 nmol/g wet). The subacute toxicity of nanoparticles leads to the induction of free radical and oxidative stress in brain tissue of roach. The increase in the activity of antioxidant enzymes causes antioxidant defense system activation for scavenger in free radicals. Manuscript profile -

The bivalvia stock with initial mean length 2.5 + 0.9 cm were gathered from nature resources and transferred into laboratory and distributed in 10 aquariums. Nano particles were spread in oltrasonic with 400 rpm. The tanks water was emulsioned with nanoparticles by homogenizer in 14000 rpm. The treatments were exposed to 0.25, 2.5 & 25 ppm nanoparticles. The Nano zinc oxide stocks in bivalves tissue and their distribution were measured by ICP & DLS. The results showed that the most nanoparticles were observed in the treatment which exposed to 0.25 ppm pollution ( p <0.05) and the less absorbance was seen in the treatment which exposed to 25 ppm (p<0.05). The DLS test showed that the nanoparticles size was between 10-100 nanometers which confirmed that the nanoparticles were homogenized and didn’t sequestrate. In conclusion, the observance by bivalvia can be a benefit index for measuring the Nano zinc oxide's pollution in water. Manuscript profile -

The result showed that, Cutting irrigation at both flowering and grain filling stages significantly reduced biological yield and grain yield, but the severity of this reduction was greater for stopping irrigation at flowering time. The highest grain yield was observed in the optimal irrigation treatment at 6667 kg ha-1. Non-Irrigation at the beginning of flowering and seed filling stages resulted in a yield reduction of 30 and 18.6%, respectively. The average weight loss of TKW due to stress at flowering and grain filling stages were 35.5 and 29.7%, respectively. On the other hand, stress caused an increase in protein content as well as moisture content of gluten, while the amount of zinc in grain decreased significantly. Weight loss of 1000 grains of wheat, followed by loss of starch storage increased the protein to starch ratio. There was no significant difference between nitrogen fertilizer supply from urea and ammonium sulfate except for plant height and peduncle length. Foliar application of zinc reduced stress damage on grain yield and increased zinc content from 36 to 38.2 ppm. Manuscript profile -

The statistical format of the design was factorial based on random complete blocks in 3 replications. The factors include sulfur fertilizer at three levels (zero, 250 and 500 kg.ha-1 from biosulfur or thiobacillus sulfur) and zinc element foliar application of zinc sulfate source (ZnSo4, 2H2o) at three levels (pure water spraying, solution Zinc spraying with a concentration of 0.5% and 1%). Zinc sulfate contained 34% pure zinc. The results showed that sulfur consumption had a significant effect on yield and quantitative components of wheat growth. The effect of consumption of this element on gluten, protein and grain content was also significant. Foliar application of zinc also had a significant effect on the weight characteristics of one thousand seeds, number of fertile tillers, grain yield, biological yield and leaf surface index. Also, all the qualitative traits of the grain were significantly affected by this element. The highest grain yield was obtained from the treatment of 500 kg of sulfur with 1% solution of zinc spraying at 6789 kg.ha-1. The combined use of biofuels and zinc increased the yield of wheat grains by 36%. The highest weight of 1000 grains was obtained from the consumption of 500 kg.ha-1 of sulfur and zinc foliar application with a concentration of 1% and a rate of 49.6 g. The maximum gluten in the grain was obtained from the consumption of 500 kg.ha-1 of sulfur and zinc foliar application with a concentration of 1%, respectively. Under the conditions of sulfur consumption, the positive effect of zinc foliar application on this trait increased. Zinc consumption increased the protein content by 10.3% and 17.7% for two concentrations of 0.5% and 1% of foliar application, respectively. The highest percentage of protein was obtained in the treatment of 500 kg.ha-1 of biofuels. The highest amount of zinc was recorded in the treatment of sulfur consumption of 500 kg.ha-1 along with 1% solution of zinc spraying at a rate of 63.30 mg.kg-1. The increase in leaf area index for both sulfur and zinc was significant compared to control. Manuscript profile -

A randomized complete block design with three replications was used. Treatments included: 1-Control, 2-Foliar application (9% Fe water-soluble), 3- Foliar application (6% Fe water-soluble), 4- Foliar application (9% Fe water-soluble)+ Zn, 5- Foliar application (6% Fe water-soluble)+ Zn, 6-Foliar application (9% Fe water-soluble)+ Mn, 7- Foliar application (6% Fe water-soluble)+ Mn, 8- Foliar application (9% Fe water-soluble)+ Zn+Mn, 9- Foliar application (6% Fe water-soluble)+ Zn+Mn. Results showed a significant effect of Foliar micronutrients on shoot length, Internode length, root dry weight, leaf dry weight, soot dry weight, Stevioside, Rebaudioside, Glycoside, chlorophyll a, chlorophyll b, total chlorophyll, chlorophyll b/a, Fe, Zn and Mn content, but the effect of Treatments on P and Ca content is not significant. The Best Results in Foliar application (9% Fe water-soluble) + Zn+Mn treatment was obtained. The impact on the amount of phosphorus and calcium treatments were not significant. Because the micro-nutrients applied as foliar application is sent, an increased impact on soil phosphorus and phosphorus absorption and thus no plant phosphorus content is also due to the lack of elemental calcium treatments and applications by spraying, can have no effect on the absorption of calcium soil. Most of the glycosides in the treatment of iron (nine percent soluble in water) + Zn + Mn and lowest in control 7.55 and 3.94 respectively with an average of dry matter was obtained. Most of the shoot in the treatment of iron (nine percent soluble in water) + Zn + Mn and lowest in control respectively 81 and 58 cm respectively. Fe + Zn + Mn combination treatment compared to other treatments bigger share of Stevia in the lengthening of internodes were at least internode length, with an average of 3.03 inches was in control. Lowest Steviosid with an average of 2.25% of dry matter in the Amdo control Fe + Zn + Mn combination treatment compared to other treatments had a bigger share in the increase in the Stevia plant Steviosid. The highest Rybvdyvzyd in the treatment of iron (nine percent soluble in water) + Zn + Mn and iron treatment (six percent soluble in water) + Zn + Mn with an average of 2.63 and 2.53 percent of the dry matter and least control it. In between treatments, foliar iron (not water-soluble iron content) + Zinc + foliar fertilizer spray six thousand four hundred manganese fertilizers more effective than other treatments the traits were measured.

Experimental treatments administered included plant density on three levels (D1=65000, D2=75000 and D3=85000 plant per Hectare plant density). The second factor includes: zinc foliar application in four treatments (F0=control, non application of zinc, F1=zinc foliar application in V12 stage, F2=VT stage and F3= zinc foliar split application in two stages of V12 and VT based, on corn developmental growth stages). Results showed that plant density effects on grain yield, total dry matter, harvest index, 1000 grain weight, leaf area index and grain number in ear were significant (p= 0.01). In addition zinc foliar application effects on grain yield, total dry matter, harvest index and 1000 grain weight were significant (p= 0.05). But interaction between of plant density and zinc foliar application had not a significant effect on above character mentioned. The highest grain yield (equal to 9843.3 kg per hectore) was obtained at the density of 75000 plants with zinc foliar split application in two stages of V12 and VT. The lowest grain yield (equal to 7751.9 kg per hectare) was obtained at the density of 65000 plants with non application of zinc. The highest Biological yield (20276.07 kg per hectare) belongs to D2 with non application of zinc and the lowest rate (15960.31kg per hectare) obtained in D1 with F1 treatment. The most Grain number in ear observed in zinc foliar split application treatment in two stages of V12 and VT. Maximum of LAI belong to D2 with F3 treatment. In generally, planting of 75000 plants per Hectare and zinc foliar split application in two stages of V12 and VT, lead to the highest of LAI and harvest index in D2 treatment and finally result to the highest grain yield.

The minimum inhibitory concentration (MIC) of Zinc oxide-doped nanopowder and minimum bactericidal concentration (MBC) were determined. The mean diameter zone of the inhibitory growth of strains of E. coli PTCC 1399 and E. coli (1) and E. coli (2) were 22.5, 18.5, and 15.4 mm respectively at a concentration of 50 mg/ml and the mean diameter zone of the inhibitory of S. aureus PTCC 1189, S. aureus (1) and S. aureus (2) standard strains were 24.5, 20.4 and 19.5 mm. In this concentration. MIC for E. coli PTCC 1399 was 1.75, and E. coli (isolate 1) and E. coli (isolate 2) were 1.55 and 3.13 mg/ml, respectively. In the case of further experiments, this nanoparticle can be used as a preservative. Manuscript profile -

This experiment was carried out under the pot conditions in cocopeat and perlite medium and Hoagland's nutrient solution was used to irrigate tomato seedlings. Tomato seedlings were sprayed with two concentrations (0 and 5 mg/l) zinc oxide and/or two dose (0 and 5 mg/l) of salicylic acid with three-day intervals during two months. Single and combined foliar application of salicylic acid and zinc oxide improved plant growth and fruit fresh weight. The applied treatments increased plant height, shoot fresh weight, root fresh weight, and fruit fresh weight. Individual and combined treatments of salicylic acid and zinc oxide also significantly increased the content of photosynthetic pigments, including chlorophyll a (Chla), Chlb, and carotenoids. A significant increase in the activity of catalase enzyme was recorded due to the foliar spray of zinc oxide and salicylic acid, especially the combined treatment. Peroxidase enzyme activity also showed an increasing trend in response to foliar application of zinc oxide and salicylic acid. Overall, this study provided physiological evidence on how the application of ZnO and salicylic acid in appropriate concentration can improve primary metabolism and antioxidant system. It is obvious that performing further researches, especially at molecular levels, can improve our knowledge in the field. Manuscript profile -

Th MoreTo evaluate the effect of foliar application of zinc and boron fertilizers on quantitative and qualitative characteristics of grain maize, an experiment was conducted with two factors using factorial in a randomized complete block design in Sar-e Pol-e Zahab. The first factor was zinc in four levels ( zero, 0.7, 1.4 and 2.1 kg/ha-1 ) and the second factor was boron in four levels ( zero, 0.3, 0.6 and 0.9 kg/ha ). Summary results showed that the effect of zinc and boron factors were significant on the stem diameter, number of kernels per row, 100 kernel weight, leaf area index, the amount of zinc and boron in the grain, protein percent and yield and grain yield at the 1% level statically. By increasing the amount of zinc fertilizer consumption, increased the stem diameter, leaf area index, number of kernel per row, 100 kernel weight, the amount of Zn and B in the grain, the amount of protein in the grain and the grain yield. The highest and lowest grain yield belonged to 2.1 kg/ha of Zinc and without the consumption of Zinc fertilizer treatments with 9.560 and 8.000 t ha-1 respectively. The 0.6 kg/ha of boron fertilizer treatment had greatest effect on the stem diameter with 28.9mm, leaf area index with 3.89, seed depth with 11.67 mm, number of kernels per row, with 41 grain and grain yield with 9.43t/ha, and this treatment was the best one. The effect of Zn and B fertilizer interaction on the yield and yield components showed that the treatment of 2.1 kg/ha oh zinc × 0.6 kg/ha boron was superior for all traits such as grain yield with 10.93 t/ha.
