Reducing the environmental risks of chemical fertilizers application in barley production by using nano-fertilizers and plant growth regulators

This experiment was carried out with five treatments and three replications, in Iran. The treatments included foliar application of nanofertilizer, chemical fertilizer, abscisic acid (ABA), kinetin, and control. Results showed that the grain protein percentage of barley increased by 32% in kinetin treatment compared to the control. According to the results, ABA and control treatments did not cause significant differences in most measured barley traits. The highest grain and biological yield of barley were associated with the treatment of kinetin and nanofertilizer. According to the results and given the problems arising from chemical fertilizers, it could conceivably be inferred that nanofertilizer and kinetin can be appropriate substitutes to enhance the quantitative and qualitative yield of barley.
