The application of chelated forms of micronutrient fertilizers in sorghum cultivation

Experimental studies of the effect of chelated forms of fertilizers on sorghum yield in arid conditions have been carried out. It is found out that to increase productivity and improve the main economic characteristics of a crop, it is advisable to use liquid chelated micronutrient fertilizers Reasil Forte Carb-Ca / Mg / B-Amino and Reasil micro Amino Zn as foliar application in the phase of 5-7 leaves (first treatment) with subsequent treatments after 10 days. It is proved that this method provides an increase in the yield of grain and green mass of sorghum by 0.27-0.60 and 27.1-39.9 t/ha, respectively, and also increases the content of valuable amino acids in the green mass: arginine, threonine, isoleucine, valine, and phenylalanine, which in turn increases the nutritional value of sorghum green mass for feeding farm animals. It is concluded that foliar application with micronutrient fertilizers reduces plant stress from unfavorable climatic conditions, which leads to stabilization of yields over the years and partially removes dependence on weather conditions.
