This study was conducted to determine the effects of foliar application of synthetic amino acids fertilizers which are called Aminolforte, Humiforte, Kadostim and Fosnutren on yield of barley plants and its quality properties as well on nitrogen use efficiency. An experiment based on complete randomized block design was carried out in Eslamshahr in five replications and four treatments of 1: No foliar application (control), 2: foliar application of all amino acids at four stages of tillering, stem elongation, heading and grain filling, respectively, 3: treatment 2 without application of Aminolforte and 4: treatment 2 without application of Kadostim. The results showed a significant increase in grain yield and a decrease in the number of the spike per square meter. 1000 grain weight increased 24, 24, and 12 percent in treatment 2, 3, and 4 respectively. The number of grain per spike also increased significantly in foliar application treatments. Foliar application of amino acids resulted in a significant increase in nitrogen use efficiency as well in nitrogen uptake efficiency by treatments. Crude protein has increased in treatment 2 (11.5%), 3 (10.5%), and 4 (3.5%) significantly. Amount of K increased 13 percent in foliar application treatments relative to the control. Composition of amino acids in prolamin fractions of barley grain has changed due to foliar application of these fertilizers in which the most changes has seen in the amount of Glycine (-21%), Valine (-18%), Alanine (60%), Lysine (66%), Isoleucine (26%), and Methionine (33%). | ||
