Soil contamination with heavy metals such as arsenic has harmful effects on human health and agricultural products. Arsenic (AS) is one of the heavy metals which are highly toxic and carcinogenic. This research was conducted to study the effect of organic manure on increasing the Arsenic absorption ability by Cress plant in the greenhouse of the Agriculture and Natural Resources Research Center, Khuzestan, Iran, according factorial experiment based randomized completely design with three replications. Main factor included two levels of organic substance (0 and 10 tons per hectar) and three levels of arsenic concentration (0, 20 and 40 ppm) belonged to sub factor. Mean comparison result revealed increasing arsenic concentration led to increase arsenic accumulation in shoot plant (14.1 ppm), also this trend seems in transfer coefficient trait so cress can be used as a purifier plant to reduce arsenic contamination of the soil. It need to mention by increase arsenic concentration, shoot dry weight decreased (0 ppm arsenic concentration had 20.1 gr per flowerpot but 40 ppm treatments had 0.7 gr). Finally according to contamination symptoms (Necrosis and chlorosis) on cress plant at 40 ppm concentrations and reduced plant shoot dry weight at this concentration, it is recommended to use the cress plant for purification of soil contaminated less than 40 ppm arsenic concentrations. It is noteworthy advised according plant's ability to absorb arsenic and other heavy elements, sowing of this plant as food should be avoided in the contaminated fields. Manuscript profile

Fertilizer management plays an important role in obtaining satisfactory yields from maize. In addition, fertilizer management is essential for achieving sustainable agriculture and protecting the environment. This research was conducted by split plot experiment based on randomized complete block design with four replications. Main factor was integrated with chemical and biological fertilizers in four levels that included 100, 75, 50, 25% quantities of nitrogen and phosphorus chemical fertilizers and with zero and 100% of biological fertilizers. Sub factor was three types of maize hybrids including Single cross 704, Single cross Karon 701 (SLD 45/1/2-1× MO17), Single cross Mobin (SLD 45/1/2-1× SLH 2/29/14/2-4/1). Analysis of variance indicated effect of fertilizer on all measured traits instead seed oil percentage and chlorophyll index was significant but effect of hybrids on all traits instead seed protein percentage was not significant. Interaction effect of treatments on seed yield, seed protein percentage and seed oil percentage was significant at 5% and 1% probability level, respectively. According result of mean comparison effect of different level of fertilizer treatment of 50% chemical fertilizer + 100% bio-fertilizer had highest amount of Biological yield (26.49 t.ha-1), harvest index (56.71%), protein yield (1.19 t.ha-1), oil yield (1.18 t.ha-1), and chlorophyll index (53.04), although hybrid SC.704 by 50% Chemical fertilizer + 100% bio-fertilizer had higher seed yield (15.14 t.ha-1), seed protein percentage (9.98%) and seed oil percentage (9.48%). Finally according result of this research use up biological fertilizers with half the recommended amount of chemical fertilizers is the greatest help towards sustainable agriculture.

In order to study the effect of zeolite and biologic fertilizers application under different irrigation regime on yield and quantitative traits in sugar beet, a research project was conducted according split-split plot experiment based on randomized complete block design with four replicates. The main factor included irrigation regime at two levels (Normal and stress), sub factor included zeolite application at two levels (with and without application) and biological fertilizers at four levels [1- Non application of mycorrhiza, 2-Application of mycorrhiza 3- Non -inoculation of bacteria 4- Inoculation of bacteria (Pseudomonas, Azotobacter, Azospirillum)] belonged to sub-sub factor. Analysis of variance results showed that interaction effect of zeolite and mycorrhiza and non-application of bacteria under normal irrigation regime on all measured traits (Instead potassium and nitrogen content) was significant. Mean comparison of treatments indicated that NZ1M1B0 treatment (Zeolite and mycorrhiza application and non-inoculation of bacteria under normal irrigation regime) had highest amount of root yield (73340 kg.ha-1), white sugar content (11.88%) and white sugar content (16.47%) but treatments of NM1B0 (Mycorrhiza application and non-inoculation of bacteria under normal irrigation regime), DM0B0 (Non-application of mycorrhiza and bacteria under stress irrigation regime) and DZ0M0B0 (Non-application of zeolite, mycorrhiza and bacterial under stress irrigation regime) had highest amount of potassium content (4.45 meq.100g-1 sugar), amino-nitrogen (2.09 meq.100g-1 sugar) and sodium content (11.95 meq.100g-1 sugar), respectively. According to results of this research mycorrhiza inoculation and use of zeolite under water deficient conditions, caused improving sugar yield and consequently decreasing negative elements (Na, K, and N) under drought stress condition.

In order to evaluate the effect of different amounts of iron and manganese sulfates on wheat yield (Chamran cultivar), a factorial experiment based a randomized complete block design with three replications. The experiment treatments consisted of different concentrations of iron sulfate )Including; zero, 1500, and 3000 grams per hectare) and manganese sulfate (Including; zero, 1500, and 3000 grams per hectare(. The results showed that there was a significant difference between different levels of iron sulfate and manganese sulfate in terms of seed yield and yield components and seed protein content. As the consumption of iron and manganese sulfate increased the number of infertile spike decreased. The highest number of seeds per spike belonged to the consumption of 1500 and 3000 g per hectare iron and manganese sulfates. The treatment with the consumption of 3000 g iron and manganese sulfates in comparison to the control treatment led to the increase of 1000-seed weight as much as almost 10 g. The highest seed yield with an average of 670 g.m-2 belonged to the treatment with consumption of 3000 grams of iron and manganese sulfates. As the consumption of iron and manganese sulfates increased from zero to 3000 g per hectare, protein, the content of protein, iron and manganese of seed increased significantly. The results showed that micronutrients by improving growth conditions and influencing the seed yield components can increase the seed yield and quality to some extent. In general, it can be concluded that highest yield and yield components in this experiment belonged to the treatments with 3000 g.ha-1 iron sulfate and 3000 g.ha-1 manganese sulfate.

Although herbs have been important and attractive since long time ago, they have gained such popularity due to the adverse side effects of chemical medicines that nowadays their cultivation has become among significant agricultural programs of most developed countries. In order to study the effects of chemical, organic, and biological fertilizers on Medicinal Chamomile yield and its components, a split plot experiment laid out in a randomized complete blocks design was conducted with three replications. The experimental fertilizing factors were applied as follows: chemical N as the main factor at four different levels (0, 50, 100, and 200 kg.ha-1), manure as the secondary factor at two different levels (0 and 30 kg.ha-1), and Nitroxin, an organic fertilizer, as the subordinate factor at two levels (not inoculating versus inoculating Chamomile seeds). Results revealed that chemical N and organic fertilizers significantly affected plant height, number of branches per plant, number of seeds per capitols, seed yield, 1000 seeds yield, and Nitrogen use efficiency, but there were no significant effects on root length and number of capitols per plant. The number of capitols per plant was not affected by any of the studied factors, but root length was only affected by biological fertilizer. Compared to the control, seed yield was increased 53%, 53%, and 59% respectively. Among these three experimented fertilizers, the biological Nitroxin was the most influential one on the above mentioned traits. Manuscript profile

There is a lack of sufficient information on cotton responses to time and amount of foliar application of potassium (K) under salt stress environment, The objective of this study was to investigate the effects of potassium (as Solupotasse 50% K2O and 18% S) rate and application time on yield and yield components of cotton under saline field condition. A factorial experiment based on randomized complete block design with three replications was conducted in Sabzevar Agriculture and Natural Resources Research center in 2015. Factors were: K rate (0, 1, 2 and 3%) and K foliar application time (at early flowering, at peak boll formation and at early flowering + peak boll formation). Increasing of K concentration to 3% increased plant height, sympodial branch number, boll number, boll weight, seed cotton yield and lint yield. Lint percent was not affected by potassium concentration. The highest boll number and lint yield was obtained when potassium spraying at early flowering stage whereas foliar application at peak boll formation had the highest plant height and boll weight. The maximum seed cotton yield was obtained at K application twice at early flowering + peak boll formation. The results obtained here suggest that 3% K application (as Solupotasse) at early flowering + peak boll formation stage can improve the seed cotton yield grown under salt stress environment.

In soils under wheat cultivation, soil aggregates stability is increased and destructive effects of erosion decreased, due to organic matters (OM) application. This trail was conducted in Shavoor agriculture research station to determine of mean weight diameter (MWD) under different organic matter sources and amounts in Khuzestan province (at south west of Iran) via a split plot experiment based on randomized complete blocks design with three replications during three year. Main factor included seven kind of manure (Cattle and hen manures, sugarcane filtercack and baggass, wheat straw and green manure which compared with control, without any organic manures) and three amount of manure (2.5, 5 and 10 t.ha-1) belonged to sub factor. Result of analysis of variance showed effect of different source of OM and interaction effect of treatments (Different sources and amounts OM) on MWD was significant at 5% probability level but effect of year and sub factor on mention trait was not significant. Finally, in order to increase soil aggregates stability under climate and soil in the studied area, is advised before wheat planting at least 2.5 t.ha-1 of organic matter cellulose such as cereal residues and or sugarcane bagasse to be used. Compliance with this recommendation, after at least 4 to 5 years, the positive effect of OM increase in aggregate stability is evident. Manuscript profile
