Nano-chemical fertilizers and plant growth regulators improve yield components and grain protein of wheat

Theis experiments was conducted as a Randomized Complete Block Design (RCBD) with five treatments and three replicates in Iran at ۲۰۱۵-۲۰۱۶ growing season. treatments included foliar application of nanofertilizer, chemical fertilizer, abscisic acid (ABA), kinetin, and control. Mean comparison showed that the highest wheat ۱۰۰۰ grain weight (۵۰.۳۳ g) was observed in plants treated with kinetin or nanofertilizer, while it was ۴۶ g in control plants. The highest number of grains per spike in wheat was increased by ۵۹.۲% compared to the control and grain and protein yield was improved by ۷۳.۱۵% and ۷۴.۲% compared to the control when the nano-fertilizer was applied. The grain protein content of wheat increased by ۵.۳۶% with kinetin treatment compared to the control. According to the results, ABA and control treatments did not cause significant differences in most measured wheat traits. From the results and in view of the problem of chemical fertilizers, it could be concluded that nano-fertilizer and Kinetin can be suitable substitutes to increase the quantitative and qualitative yield of wheat.
