  An experiment was conducted in order to evaluate the effects of zinc foliar application and biosulfur fertilizer consumption on yield and yield components of “Baharan” new wheat variety, in agriculture and natural resource research center of Tehran province in 2015-16. A factorial experiment in randomized complete block design (RCBD), with three replications were used. The experiment factors were three levels of biosulfur fertilizer and zinc foliar application with three levels. Biosulfur fertilizer had significant effects on Gloten, Protein, grain zinc content and also yield and yield components (TKW, no. of fertile tillers, biological and grain yield). Zn spraying increased TKW, no. of fertile tiller, grain yield, biological yield and LAI. The highest grain yield obtained from 1% Zn spraying and 500 grams biosulfur fertilizer with 6789 kg/h. the combined use of biosulfur fertilizer and Zn spraying increased wheat grain yield by 36% compared with control (Zn0S0) treatment. The maximum gluten content was obtained from application of 500 kg / ha biosulfur fertilizer and foliar application of zinc at 1% concentration. Zinc intake increased the protein content by 10.3% and 17.7% for the two concentrations of 0.5% and 1% spraying, respectively. The highest percentage of protein was obtained in the treatment of 500 kg / ha biosulfur fertilizer. The highest amount of grain zinc (63.30 mg / kg) was obtained from 500 kg / ha sulfur treatment within 1% zinc spraying.Biosulfur fertilization increased the positive effect of zinc on yield and yield components of Baharan new wheat variety.

     An experiment was conducted in order to evaluate the effects of Zn spraying and nitrogen fertilizer application on wheat under water stress condition, in varamin agricultural research center in 2005-16. a split-factorial layout within randomized complete block design with three replications were used. main plots were three irrigation treatments and sub plots were two, Zn spraying and Nitrogen fertilizer treatments with factorial arrangment. 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

  This experiment was conducted in order to investigate the effect of zinc foliar application and different levels of sulfur fertilizer on yield and wheat yield components of Baharan cultivar in 2016-2017 in Tehran Agricultural and Natural Resource Research Center. 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
