        In this paper a suitable method for safe, economical and environmentally compatible disposal of "old and waste of energetic materials" in valuable organic fertilizers is introduced. The basis of this method is hydrolysis of energetic materials in presence of Humic acid, under suitable alkaline conditions in which the bonds of energetic materials are disintegrated and its Nitrogen content is converted into  the forms of Nitrite, Nitrate Ions or Ammonia and are absorbed by Humic acid. The remained materials containing carbon of process are converted to inert materials and are trapped in Humic acid matrix. Following the process, the Product of hydrolysis reaction which is liquid fertilizer is neutralized with phosphoric acid to reach to the desired PH and additives such as micronutrients will be added to it if necessary. In this process, severe bio-environmental pollutions, resulting from application of old and routine methods for destruction and neutralizing of energetic materials, is prevented, and safety hazards for neutralizing or destruction of these materials is minimized. Generally, the Final products of this process are liquid organic/inorganic fertilizers with various formulations for the use in agronomy Manuscript profile

        Background and Objective: Humic acids are main components of natural organic matters that have many negative effects, especially reaction with chlorine and production of disinfection by-products in water. Thus, the methods for the removal of these substances from water have been considered. Enhanced coagulation is a simple, suitable and efficient process for the removal of humic substances. Method: This study evaluates the enhanced coagulation effectiveness, as a suitable method for the removal of humic substance by polyaluminium chloride as a coagulant in a concentration between 1 to 20 mg/l in jar test. Results: Dissolved organic carbon, ultraviolet absorbance, specific ultraviolet absorbance and humic acid were determined as humic substances indexes in concentration between 0.1 to 5 mg/l. According to the obtained results, high level of specific ultraviolet absorbance index in the water source showed that enhanced coagulation was necessary for the removal of humic substance. Also, according to the obtained results, the average removal efficiency obtained by enhanced coagulation for humic acid was 52%, for dissolved organic carbon was 43% and for UV254 was 57%. Conclusion: It was concluded that employing polyaluminium as a coagulant in enhanced coagulation process is inexpensive, suitable and efficient and can remove humic substance to optimum value without decreasing turbidity efficiency.

        In order to investigate the effect of humic acid on the quantitative and qualitative yield of flixweed under different drought stress conditions in the form of split plots based on randomized complete blocks with four replications in the research farm of the Faculty of Agriculture, Ghods Branch. The main factor of irrigation in 3 levels includes: normal irrigation, mild stress and severe stress in the main plots and the secondary factor of humic acid in 3 levels including: non-consumption, 100 mg/L, 200 mg/L spraying with humic acid was present in the subplots. The results of analysis of variance showed that the effect of irrigation levels at 5% and humic acid at 1% and the interaction between irrigation and humic acid at 5% were significant. The highest grain yield was related to the treatment of 200 mg/L humic acid under normal irrigation conditions. The results showed that in all irrigation levels, increasing humic acid consumption led to increased grain yield, so that in normal irrigation and mild stress conditions the least difference between humic acid levels and in severe stress conditions the highest difference between humic acid levels was observed. This means that humic acid showed the greatest effect in reducing the effects of drought stress compared to other levels of irrigation (mild stress and normal irrigation). Manuscript profile

        To evaluate the effect of humic acid on activity of antioxidant enzymes in castor bean a split plot experiment based on completely randomize block design with four replications was carried out at Islamic Azad University, Karaj Branch in 2014. Treatments were irrigation with three levels [irrigation at 80% of field capacity (S1) (normal), irrigation at 65% of field capacity (S2) (mid stress) and irrigation at 50% of field capacity (S3) (high stress)] assigned to main plots and humic acid with four levels (without foliar application, one time, twice and three times foliar application) to sub plots. In this study traits like seed yield, 100 seed weight and antioxidant enzymes were estimated. The results showed that the effect of humic acid was significant at 1% level on 100 seed weight and activity of antioxidant enzymes. Mean comparisons indicate that foliar application of humic acid could compensate relative effect of water deficit. It was also revealed that the rate of superoxide dismutase, glutathione peroxidase and catalase were increased with three times of humic acid foliar applications by 38.8, 34.75 and 37.88 percent under mid stress drought and 26.63, 41.15 and 43.14 percents under high stress drought as compared to control, respectively. Overall, it can be said that use of humic acid have different physiological effects. Humic acid not only increases seed yield of castor bean it also have a positive role in reducing water deficit effects and increasing activity of antioxidant enzymes. Manuscript profile

        To evaluate the effect of different rates of biochar and humic acid applications on physiological characteristics and grain yield of single cross 704 hybrid corn under water deficit stress, a split split plot experiment based on a randomized complete block design with three replications, was conducted during two years (2017-19) at Ahvaz. The main plot devoted to water deficit stress, with three levels irrigation (after depleting 30, 40, and 50% of field capacity as optimum irrigation, moderate stress, and severe stress, respectively) and sub-plot to biochar with 2 levels, non-application of biochar (control) and application of 4 tons per hectare of biochar, and the sub-sub plots to humic acid with 4 levels non-application of humic acid (control), and application of 2, 4, and 6 liters per hectare of humic acid. The results showed that the interaction effect of water shortage by biochar stress and water shortage by humic acid stress on grain yield, 1000-grain weight, number of grains per ear, superoxide dismutase, chlorophyll index and catalase were significant at 1% probability level. Under severe stress conditions grain yield (36.54%), number of grain per ear (36%) and leaf area index (30.36%) decreased and activity of superoxide dismutase (37.7%) increased. Acidic acid had a significant effect on all traits under study. The highest grain yield (8995.18 kg.ha-1) was related to irrigation treatment after 40% depletion of field capacity and application of 4 tons per hectare of biochar. Based the results obtained application of 4 liters per hectare of humic acid under moderate moisture stress conditions, could be recommended in arid and semi-arid conditions to save water consumption and reduce the effects of water deficit stress.

        Seeds could be deteriorated during storage. Treatment of seeds by humic acid induces metabolic and biochemical changes which accelerate seed germination and its emergence. This research was carried out to evaluate the effect of seed pretreatment potassium humate on its deterioration under laboratory and greenhouse conditions. The experiment was carried out in a 5 × 4 × 3 factorial experiment using completely randomized design with three replications. Experimental factors were three levels of potassium humate (control, one and two parts per 1000 potassium humate), four wheat varieties (Shirodi, Darya, Morvarid and Chamran) and five heating times (zero, 48, 72, 96 and 144 hours). Results showed significant differences in simple effect of variety and effect of potassium humate × heating times for shoot length; simple effect of heating times and effect of potassium humate × varieties for germination percent; effect of potassium humate × varieties × heating times for radicle length, shoot dry weight, seminal roots dry weight and seedling dry weight. Pretreatment of seeds by using 2/1000 potassium humate produced × longest radicle roots in Shirodi, Darya, Morvarid and Chamran respectively with 72, 72, 144 and 96 hours heating times. The highest root dry weight was produced by 2/1000 potassium humate and 48 and 72 hours of heating times on Shirodi and Chamran, respectively. Application of 1/1000 of potassium humate produced the highest seedling dry weight in Shirodi, Darya and Morvarid with 48, 72 hours of heating times and without heating, respectively. Results also revealed that different varieties responded differently to potassium humate treatment at different heating times. It can be concluded that longer heating durations affected wheat characters at early growth stages and pretreatment of seeds by potassium humate can decrease seed deterioration.  Manuscript profile

        In order to investigate the effect of interaction of mycorrhiza and humic acid on morphological characteristics, seed protein percentage, and nutrients concentration of red beans, an experiment was conducted as factorial randomized complete block design in three replications. Research factors included mycorrhiza at three levels of control, Glomus intraradice, Glomus mossea, and also foliar application of humic acid at three levels of control, 15, and 30 mg/l. The experiment was conducted as pot and under normal and uncontrolled conditions. Measured traits included plant height, root length, number of plant pods, number of seeds in each pod, 100 seeds weight, seed protein, and nitrogen and phosphorus concentration of leaves. Application of mycorrhiza and humic acid increased measured traits except for the number of seeds in each pod and 100 seeds weight. There was no significant difference between the two strains and also levels of 15 and 30 mg/l humic acid in the studied traits. Generally, foliar application of 15 mg/l humic acid in the presence of mycorrhiza was more effective than other treatments. Manuscript profile

        In order to study the effect of water deficit and the application of humic and salicylic acid on physiological traits, yield and yield components of corn, an experiment was carried out as a split-plot based on randomized complete blocks design with three replications at the research field of Islamic Azad Universityof Birjand, Iran in 2014. The main factor was irrigation in three levels (supply of 33, 67 and 100% water requirement) and the sub-factor was humic and salicylic acid application in 4 levels (application of humic acid, salicylic acid, humic + salicylic acid and no application). The results of variance analysis showed that irrigation significantly affected traits of physiological, seed yield components and yield but humic acid and salicylic acid application significantly affected chlorophyle index, stomatal conductivity, 1000-seed weight and seed yield. Also, interaction effect of irrigation and humic acid and salicylic acid was no significant on measured traits. Chlorophyle index, stomatal conductivity, ear number per m2, row number per ear, seed number per row, seed number per ear and 1000-seed weight significantly decreased by 15.6, 35.6, 41.2, 14.1, 33.9, 61.8 and 40%, respectively with the decreas of water requirement from 100 to 33%. Seed yield and biological yield in treatment of 100% water requirement supply, had significantly superiority 3.9 and 2.4 times, respectively as compared with treatment of 33% water requirement supply. Chlorophyle index by 7.5, 7.7 and 8.9%, 1000-seed weight by 22.5, 26.6 and 20.7% and seed yield by 26.5, 18.5 and 21.7%, significantly increased with application of humic acid, salicylic acid and humic acid + salicylic acid respectively as compaed with no application of this acids. The results showed that supply of 100% water requirement and independent application of humic acid or salicylic acid can increase seed yield of corn. Manuscript profile

        This study was performed to investigate the effect of mycorrhiza fungus and different levels of humic acid (zero, 200 and 400 mg/l) and salicylic acid (zero, 100 and 200 mg/l) on physiological characteristics and essential oil content in three cultivars Lemonella, Citronella and Varigated. Lemon balm (Melissa Officinalis L.) was implemented in 1397 in a greenhouse in northern Iran. The experiment was performed as a factorial in a completely randomized statistical design with 3 replications. Mycorrhiza and humic acid treatments were applied at the time of seed sowing and salicylic acid was sprayed in two stages (second and third weeks of pot cultivation). The results of this experiment showed that all treatments had a significant effect on the measured variables. The highest proline content was obtained in Citronella cultivar and control treatment and The highest phenol, carbohydrate, essential oil percentage in the treatment of mycorrhiza fungus+ humic acid 400 mg/l + salicylic acid 100 mg/l were obtained in Varigated, Citronella and Lemonella cultivars, respectively. Also the highest amount of flavonoids in the treatment of mycorrhiza fungus+ humic acid 400 mg/l + salicylic acid 200 mg/l in Citronella cultivar and the highest total antioxidant activity in the treatment of mycorrhiza fungus+ humic acid 200 mg/l + salicylic 200 mg/l in Lemonella cultivar was observed. In general, the results of this experiment showed that the application of mycorrhiza fungus with humic acid 400 mg/l and salicylic acid 100 mg/l in Lemonella, Citronella and Varigated cultivars improved the physiological characteristics and essential oil of Lemon balm.

        In order to investigate the effect of biochar fertilizer and humic acid foliar application on quantitative and qualitative characteristics of Roselle (Hibiscus sabdariffa) a split plots experiment in a randomized complete block design was performed with three replications in the Research Field of Islamic Azad University, Arak Branch during 2017-2018 and 2018-2019. Experimental factors included 3 levels of biochar (non-consumption or control, 4 tons ha-1, and 8 tons ha-1) and the second factor of foliar spraying of humic acid 82% at 4 levels (non-consumption or control, 100 mg/l, 200 mg/l, and 300 mg/l. Interaction of biochar and humic significantly affected fruit yield. In the treatment with 8 t/ha biochar and 200 mg/l humic acid, the fresh weight of shoots was 465.1 g plant, showing an increase by 32% compared to the minimum value obtained from fertilizer control. At different levels of humic acid, consumption of 8 tons per hectare biochar always increased fruit yield compared to non-biochar treatment and consumption of 4 tons per hectare biochar. The interaction of biochar and humic acid on color intensity was significant. In the combined treatment of 8 tons per hectare of biochar and 100/l of humic acid, a red index of 14.67 was obtained. At different levels of humic acid, consumption of 8 tons per hectare biochar increased the red color index. Considering the fact that the intensity of red color in Roselle indicates the quality of the product, the consumption of 300 mg per liter humic acid and 8 tons per hectare biochar increased this trait, improving its functional traits.

        Fenugreek (Trigonellafoenum- graecum L.) is one of the significant medicinal plants and application of organic materials is very important for achieving maximum yields of that. In this study, the effects of applications of humic acid and planting density on biochemical characteristics of fenugreek were evaluated under field conditions. Treatments were of three levels of humic acid (0.5 and 10 kg ha-1) and two plant density (25 and 50 plants/m2). This experiment was carried out as factorial based on randomized completely block design with three replications in research farm of University of Birjand, Iran, during growing season 2016.The leaves` antioxidant compounds (antioxidant activity, total phenol and anthocyanin) were recorded at flowering stage. The results were showed that humic acid had significant effect on most biochemical characteristics(antioxidant activity, flavonoid content, total phenol and carbohydrate). The highest of antioxidant activity (64. 67%) and carbohydrate (6.73 mg/g) were observed in 10 kg/ha humicacid, while the lowest antioxidant activity (50.03%) and carbohydrate (3.45 mg/g) were recorded in control. Also, the humic acid uses significantly increased photosynthetic pigments (total chlorophyll, a, b and carotenoids). The highest and the lowest total chlorophyll content were observed (4.51 mg /g) in 10 kg/ha humic acid andcontrol (3.18 mg/g), respectively. Based on the results, the highest flavonoid content (6.43 mg/g) was obtained in the plant density of 25 plants /m2, whereas the lowest flavonoid content (5.46 mg /g) was in planting density of 50 plants /m 2. There were significant differences in the total phenolic and flavonoid content due to interaction plant density and humic acid treatments, in which the highest amount of total phenolic content (42.07 mg/g) was observed in 10 kg/ha humic acid with the plant density of 25 plants /m2.and the lowest content was recorded (41.86 mg /g) in the control with density of 25 plants /m 2. According to the results, using 10 kg ha-1 of humic acid and planting density of 25 plants/ m2 had a significant role in increasing biochemical characteristics of fenugreek. Manuscript profile

          Abstract Salinity is one of the most important ecological stresses which reduces productivity. Humic acid as an organic acid and ascorbate as a strong antioxidant can be effective in improving plant yield under salinity stress.In this study, to investigate the effect of ascorbic acid and humic acid on the amount and chemical constituents of essential oil (Dracocephalum moldavica L.) under salinity stress, a factorial experiment in a completely randomized design with three replications was conducted at research greenhouse of faculty of Agriculture, Ferdowsi University of Mashhad, Iran. Treatments included salinity at four levels (0, 50, 100 and 150 mM), humic acid and ascorbic acid at three levels (0, 100 and 200 mg / l).The aerial parts of plant in blooming were collected and were extracted by steam distillation method using Clevenger apparatus and its components were separated and identified by gas chromatography and gas chromatography coupled to mass spectrometry. The essential oil content decreased with increasing salinity stress and application of salt stress moderators (ascorbic acid and humic acid) improved this trait. So that at 150 mM salinityit reached to the lowest level (0.2%) and application of 200 mg / l humic acid increased 51.61% of essential oil compared to control. Most of the essential oil constituents in control treatment (no use of moderators and no salinity conditions) were geranial (36.65%), neral (31.94%), geraniol (15.56%), geranyl acetate (0.66), Trans- 4,2- heptadienal (1/25%), linalool (1.09%), pulegone (0.95%) and verbenol (0.4%) which included 99.5% of the essential oil components respectively by 36.65, 31.94, 15.56, 11.66, 1.25, 1.09, 0.95 and 0.4 percent. In different levels of salinity stress with 100 mg/l of humic acid treatment and application of salt stress moderators (100 and 200 mg/l ascorbic acid and 200 mg/l of humic acid) a large number of combinations was observed compared to control treatment. These includedalpha-pinene, beta-pinene, camphene, camphor, alpha-thujone, nerol and thymol.   Manuscript profile

        The aim of this study was to investigate the effect of artichoke (Cynara scolymus L.) seeds priming with plant growth-promoting rhizobacteria and extracted humic substances from biochar of Oriental plane (Platanus orientalis) tree on their seeds germination and seedling growth indices. For this purpose, in-vitro culture was performed in the form of factorial in a completely randomized design with four replications, totally in 36 experimental units, in the laboratory of soil science department, University of Zabul, in spring 2021. The first factor (humic substances) was in three levels including: seed priming with distilled water (control), fulvic acid and humic acid. The second factor (plant growth-promoting rhizobacteria) was in three levels including: seed priming with physiological serum (control), strains of Pseudomonas sp. R27N7 and Staphylococcus sp. R38N2. The results showed that R27N7 and R38N2 bacterial strains reduced the mean germination time by 10.93% and 11.23%, respectively, compared to the control. The effect of fulvic acid treatment on variation of measured indices was not significant compared to control. But, humic acid treatment increased indices of Seedling height by 90.33%, seedling dry weight by 90.70%, germination percentage by 61.32%, germination rate by 62.50%, mean daily germination by 60.19% and vigor index I and II by 2.76 times compared to the control. According to the results of this study, artichoke seeds priming with both of the plant growth promoting rhizobacteria strains can reduce mean germination time of seed. Also, seeds priming with humic acid can improve dry weight of seedling and most of seed germination indices. It seems that the improvement of these indices is mostly influenced by the plant growth hormone-like properties of humic acid and also plant growth promoting properties of both bacterial strains, especially their ability to produce of indole-3-acetic acid.

        a factorial pot experiment was conducted in the form of a complete random block design with three repetitions under greenhouse condition. The first factor of the study was mycorrhiza at three levels, namely control (no mycorrhiza), Glomus intraradices strain, and Glomus mosseae strain. The second factor of the study included three levels of humic acid, namely 0 (control), 15, and 30 mg L-1. The results showed that with the application of mycorrhiza and humic acid, the number of seeds per plant, seed weight per plant, chlorophyll index, percentage of seed protein content, and nitrogen, phosphorus, and potassium contents of leaves increased. The highest seed weight per plant (13.47 g) was recorded in the red beans treated with 30 mg L-1 of humic acid + Glomus intraradices strain and 13.01 g and 13.72 g in the plants treated with 15 and 30 mg L-1 of humic acid, respectively along with Glomus mosseae strain. Also, the highest percentage of seed protein was 26.15% obtained from the treatment with 30 mg L-1 of humic acid + Glomus intraradices and 25.23% and 27.93% in the treatments with 15 mg L-1 and 30 mg L-1 of humic acid, respectively along with Glomus mosseae. Maximum leaf nitrogen content (5.85%) was obtained from the application of 30 mg L-1 of humic acid with Glomus mosseae.

        Iron is one of the essential elements for plant growth. Iron deficiency is one of the problems of calcareous soils in Iran. In order to investigate the effect of iron nanoparticle composite coated with humic acid on the agricultural characteristics of tomato plants, a factorial greenhouse experiment was conducted in the form of a completely randomized design with three replications. The test factors include the first factor, the type of iron fertilizer (iron sulfate and iron nanoparticles Fe3O4), the second factor of humic acid (use of humic acid and the absence of use of humic acid), the third factor of iron concentrations (0, 25, 50, 75, 100, 200) mg/kg. Infrared spectroscopy results showed that nanoparticles coated with humic acid behaved differently than iron nanoparticles due to the creation of new functional groups. Also, the results showed that Fe3O4 nanoparticles coated with humic acid at a concentration of 50 mg/kg caused a significant increase in plant height (31%), shoot fresh weight (68%), and iron concentration in the plant by 2.4 times) compared to the control treatment (treatment without fertilizer). The results of this research show that applying Fe3O4 nanoparticles coated with humic acid for agricultural products can improve the agronomic characteristics of tomatoes, so this fertilizer can be introduced as a suitable option for providing the iron needed by the plant.

        Today, the use of organic fertilizers is increasing. The humic substances are a mixture of various organic compounds that are derived from the remains of plants and or animals.Humic acid is one of the compounds that today are widely used in research as well as commercial uses. The plant grown in soils that have enough humic substances, are less influenced by stress, will produce healthier plant and more product. Summer Savory (Satureja hortensis L.) is an annual plant that is widely cultivated. Essential oil of this plant has antimicrobial properties and inhibits the growth of some bacteria. All vegetative shoots contain essential oil which has antimicrobial, anti-oxidant and anti-fungal. In order to investigate the organic matter of humic acid in comparison to chemical fertilizer and manure, a research was carried out in years 2009-2011 for 3 years in Khojir research station a form of a randomized complete block design with six treatments and 3 replications. The treatments included humic acid, fertilizer (N100P80K100), manure (30 ton/ha), humic acid mixture with half fertilizer, humic acid mixture with 10 tons/ha of manure compared with the control. According to the results, the use of humic acid increased significantly in most of the studied traits such as root length, plant height, number of lateral branches, leaf dry weight in plant, shoot dry weight, shoot fresh weight, dry shoot yield, essential oil yield , seed yield compared to control. Chemical fertilizer with 28.88 kg, manure with 27.41 kg, humic acid with 23.34 kg, mixture of humic acid with chemical fertilizer with 22.19 kg and mixture of humic acid manure with 22.92 kg per hectare had significantly increase in essential oil yield than the control group (16.87 kg). Thus in summer savory cultivation, the humic acid consumption due to increased dry matter yield and essential oil yield, is recommended. Manuscript profile

        An experiment was conducted in order to evaluate the effects of humic acid spraying on  grain yield and yield components of wheat, in agricultural research and natural resources center of Tehran province, in 2010-11. a split-plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments contains of normal irrigation, non-irrigation at start of flowering stage (light stress) and non-irrigation at start of grain filling stage (severe stress), and sub plots were four levels of Humic acid spraying (spraying with pure water, Humic acid spraying with 200, 400 and 600 mg.l concentration). The result showed that, all of yield components except plant height and peduncle length affected significantly by drought stress on reproductive growth stage. The grain yield was significantly affected by Both light and severe stress treatments. The grain yield was decreased by 15.4% and 30.9% for light and sever stress respectively. humic acid spraying increased growth rate and leaf production and also accelerated maximum LAI achievement. The grain yield increased with Humic acid spraying for all three concentrations but, this was only significant in 600 mg.l.Protein and phosphorous percentage increased significantly with Humic acid spraying.. Polynomial equation for LAI changes manner, showed that the maximum LAI was achieved in higher amount and erlier time for normal irrigation and higher concentration of humic acid.    Manuscript profile

        Two separate tests were conducted in laboratory, to evaluate the germination behavior of sugar beet under effects of priming treatments. The first experiment examined the effect of time (3, 6, 12, 24 and 48 hours) and concentration (25, 50, 100, 200 and 400%) of two types of stimulants (Seed-start and Humic acid). The second experiment is consisted of seed priming times (3, 6, 12, 24 and 48) of two methods of hydration in water (running water and soaking in a Petri dish). The results showed that both tests have a significant effect on germination of sugar beet. The lowest time (3 hours) and the lowest concentration (25%) of priming of the Seed-starter and the Humic acid are desirable to improve sugar beet seed germination. The method of running water (48%) had better effect compared to soaking in a Petri dish (45%). Generally, methods of running water, soaking in a Petri dish, seed-start and Humic acid improve germination 76, 36, 79 and 64% compared to control, respectively. The impact of method and time of priming on germination rate showed the same trend like percentage of germination. Impact of stimulants can be because of nutrition element and influence of leaching with running water can be because of washing the inhibitive material on the seed coat. Seed-start treatment (Concentration of 25% with 3 hours) and leaching with running water (48 hours) can be introduced as the best treatment.   Manuscript profile

         An experiment in the form of split-plot design with randomized complete blocks was performedin three replications in Pyrmosi village of Khoi city during 1400 in order to evaluate theresponse of yield and physiological properties of red beans to the application of growthpromoters under different irrigation levels. Irrigation was considered as the main factor in threeirrigation levels, i.e., once in 8, 11 and 14 days, and the growth promoting compounds wereviewed as the secondary factors in 5 levels, i.e., the use of humic acid mixed with irrigationwater, amino acid foliar spraying, rooting stimulant, potassium and non-use of growthpromoters was (control). The results of analysis of variance indicated that irrigation had asignificant impact on all the traits studied, and the growth promoters affected the leaf relativewater content, chlorophyll a, protein percentage, number of lateral branches, seed yield, andharvest index significantly. The interaction of the two factors had significant effects on thenumber of lateral branches, seed yield, harvest index, and seed protein percentage. Theapplication of humic acid resulted in increased seed yield, and as the water deficit increased, theeffect of humic acid on increasing seed yield became significant. The highest seed yield was3076.12 kg per hectare observed in the irrigation level of once every 8 days and under thehumic acid treatment, and the lowest level of this trait was 1220.96 kg observed in the irrigationlevel of once 14 days and under the control treatment. It seems that increased irrigation intervalduring the growing season led to yield loss and degradation of physiological properties such asleaf area index, chlorophyll, and leaf relative water content, and the use of compounds such ashumic acid moderated the decreasing drought stress effects to some extent.  Manuscript profile

        Plant germination and establishment is one of the challenges of farmers in arid and semi-arid areas, and organic priming is a suitable solution to reduce environmental pollution caused by the use of chemical inputs. For this purpose, a factorial research was carried out in the form of a completely randomized design on the seeds of Lemon balm (Melissa Officinalis L.) in three replications in the seed technology laboratory of the Islamic Azad University, Karaj branch. The treatments of this experiment include five levels of priming (chitosan, humic acid, vermicompost, distilled water and control (no prime)) and four levels of drought stress (0, 0.3, 0.6, 0.9 Mpa). The results showed that drought stress decreased the germination percentage, growth, and quality of lemongrass seedlings in non-prime conditions, and as the intensity of drought stress increased, the growth of seedlings decreased. Chitosan, humic acid, and vermicompost priming was more effective than distilled water priming (hydropriming) in increasing germination characteristics and coping with drought stress, and reduced the negative effects of drought stress. Seed priming with the mentioned treatments caused a decrease in proline concentration and ascorbate peroxidase enzyme activity. Priming with humic acid and vermicompost in non-stress conditions led to 19.52% and 19.93% germination increase in lemon balm respectively, compared to the treatment without priming and 0.9 MPa drought stress conditions.

        In order to determine the effect of foliar application of micronutrient fertilizers and humic acid consumption on the yield and yield components of sesame in the delayed planting date, an experiment was conducted in the research farm of Iraqi Mahalle station in the crop year of 2022. This research was carried out as a completely randomized block design with 9 treatments in 3 replications in the research farm of the Iraqi Mahalle. In each plot, 5 rows were planted, the distance between rows was 40 cm and the distance between replications was 3 meters. The studied traits included plant height, harvest index, seed yield, thousand seed weight and biological yield. The results obtained from this study showed that the treatment with humic acid + micronutrient, control and control + irrigation fertilizer + humic acid fertilizer had the highest biological performance, and the lowest biological performance was related to humic acid irrigation fertilizer and irrigation fertilizer + micronutrient. Also, the weight of one thousand seeds in the control group and the eighth treatment was significantly lower compared to other treatments. These results show that the use of micronutrient fertilizers and humic acid could significantly increase the weight of a thousand seeds. Finally, the seed yield was significantly higher in control, control + humic acid seed, and control + humic acid seed + micronutrient than other treatments. These results show that application of humic acid has better effects on grain yield than other treatments. Manuscript profile

        Identifying the critical time and timing of plant irrigation based on a precise and basic plan is the key to water conservation, improvement of irrigation operations and plant tolerance to water shortage in agriculture. In recent years, vesicular arbuscular mycorrhizal fungi have been used in many plants to deal with dehydration and drought stress. In this regard, an experiment was conducted as split-plot in the form of randomized complete block design with 3 replications in the Yasuj region at years 2015 and 2016. Water stress was considered as the main factor in the form of irrigation after 30, 60, 90, 120 and 150 mm of evaporation from the evaporation pan class A and mycorrhizal fungus was considered as a secondary factor in the form of no application, application of Glomus mosseae and application of Glomus intraradices. The results showed that the interaction of irrigation and mycorrhizal fungi on flower phosphorus, flower yield, biological yield and water use efficiency of Borage was significant. In irrigation levels after 60, 90, 120 and 150 mm of water evaporation from the evaporation pan, the use of mycorrhizal fungi Glomus mosseae and Glomus intraradices compared to the absence of fungi respectively increased the yield of plant flowers (30.04% and 27.35 %), (90.2% and 90.98%), (93.21% and 94.1%) and (81.73% and 78.86%), also, at these levels of irrigation, biological yield and water use efficiency of Borage flower achieved a significant increase in the presence of mycorrhizal fungus, compared to the absence of mycorrhizal fungus application. Application of both strains of mycorrhizal fungus Glomus mosseae and Glomus intraradices in irrigation levels after 90, 120 and 150 mm of water evaporation from the evaporation pan compared to no application of mycorrhizal fungus, respectively, resulted in a significant increase in the harvest index of Borage flower (44.55% and 43.36%), (13.21% and 15.96%) and (5.6% and 5.41%) and flower phosphorus (44.69% and 20.45%), (150% and 125%) and ( 267.74% and 235.48%). Mycorrhizal fungus was able to moderate the negative effects of drought stress and increase the above-mentioned traits in those irrigation levels, and based on the results of this study, irrigation treatment after 90 mm of water evaporation from the evaporation pan + the use of Glomus mosseae mycorrhizal fungi is recommended.

        Yield and yield components response of chickpea to time and different levels of humic acid foliar application was studied in Bardaskan (northeast Iran) in 2011. experiment was carried out as factorial based on a complete randomized block design with three replications. Factors were foliar application time of humic acid  at three levels (three leaf, flowering and poding stages), and different levels of humic acid concentrations (0, 2, 4 and 6 Lit.ha-1). Humic acid 8% was used with Humax trade name containing 80% humic acid, 5% potassium oxide and 15% fulvic acid. Yield and yield components response were different to foliar application time. Foliar application at flowering stage had the greatest effect on pod number per plant, seed number per plant, economic yield and biological yield, while foliar application at three leaf stage had the highest effect on plant height and lateral branches number in plant. Increasing humic acid level increased all parameters, except lateral branches number in plant. The highest pod number per plant, seed number per plant, economic yield and biological yield was obtained at 6 lit.ha-1 humic acid concentration. Overall, the result of this experiment showed that 6 lit.ha-1 humic acid application at poding stage can be recommended to achieve optimal economic performance. Manuscript profile

        The effect of irrigation intervals, humic acid and plant growth promoting Rhizobacteria (Azotobacter, Azospirillum pseudomonas) was studied on yield and yield components of wheat (Kavir cultivar) in Fashafuyeh region, Iran in 2010-2011. Experiment was carried out as split factorial based on a randomized complete block design with four replications. Main Factor was irrigation at three levels (irrigation after 80, 120 and 160 mm evaporation from class A evaporation pan) and humid acid and plant growth promoting Rhizobacteria at two levels of application and non-application were considered as sub-factors. The result indicated that water stress significantly decreased seed yield duo to a decreased seed numbers per spike. Water stress also decreased biological yield, significantly. Application of plant growth promoting Rhizobacteria significantly effected seed yield and harvest index percentage. Besides, application of humid acid increased spike number per unit area and biological yield in high stress condition (irrigation after 160 mm evaporation from class A evaporation pan). According to the results, application of plant growth promoting Rhizobacteria and humid acid as two important biological fertilizers can reduce inverse effect of water deficit stress on yield and yield components of wheat.

        Selenium, known as a key ingredient for human and animal health, can play an important role in the antioxidant mechanism in plants. Unfortunately, many plants fail to have enough selenium, which  has led to selenium enrichment. The aim of this study was to investigate the effect of selenium combined with fulvic acid and humic acid on nutritional value of dill. To this end, an experiment based on a completely randomized factorial design with three levels of fulvic acid and humic acid (0, 50 and 150 mmol/L) and selenium application at 5 levels (0, 6, 8, 12 and 16 mg/L) with three replications was conducted in a greenhouse. The results of this experiment showed that the effect of 50 mmol/L fulvic acids + 12 mg/L sodium selanate, was significant on morpho-physiological traits such as shoot and root dry weight, plant height, chlorophyll, essence,  amount of selenium,and antioxidant enzymes. The results indicate that selenium along with the acids increased and improved essential oilconstituents such as alpha-pinene (3.129%), beta-myrcene (2,231%), alpha-phellandene (46.14%) and carvone (74.83%).
