Abstract :
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.
