Abstract
Under the field conditions, the effectiveness of foliar application of metal-amino acid chelates including metal-glycine [Zn(Gly)2], [Fe(Gly)2], [Cu(Gly)2] and metal-methionine [Zn(Met)], [Fe(Met)], [Cu(Met)] on yield of stalk and grain as well nutritional quality of sorghum was investigated. The foliar application increased stalk and grain yield 23.8-25.16% and 16.1-20.1% for the first and second year respectively. The grain zinc, iron, copper and protein concentration was also increased significantly as compared with non-chelated and control. On the average 26.2%, 23.3%, 45% and 25.3% increase in sorghum grain Zn, Fe, Cu, and protein respectively was noted for both the growing years sprayed with [M(Gly)2] and [M(Met)] than those sprayed with non-chelated micronutrients. Significant correlation between the protein, Zn, Fe, and Cu concentration indicates that the genes affecting the grain accumulations of Zn, Fe, Cu and protein are probably closely linked. In the present study, the results obtained by foliar application of [M(Gly)2] and [M(Met)] should consider as new micronutrient sources to improve the stalk and grain yield along the nutritional quality
