Аннотация: The article presents the results of studies conducted on the effectiveness of barley foliar feeding under field experiment conditions. The studies were carried out in a field stationary experiment in a grain-vapor-tilled crop rotation system with the following rotation: green-manured fallow - spring wheat - barley - maize - spring Показать полностьюwheat. The object of the research was leached chernozem. Rotation cropping was sown on two degrees of ground fertilization - without fertilizer and with fertilizer. Urea (carbamide) was added as barley foliar feeding. Spring wheat that was sown on rape plant green-manured fallow served as the forecrop to the barley. Soil fertility heterogeneity was determined by examining barley crops during the tillering period (biomass scanning). Unmanned aerial vehicles manufactured by Krasaeroskan were used for this purpose. The results of NDVI index determination in the field experiment formed the basis for determining the mineral nitrogen fertilizer doses. Such doses were refined by tissue diagnostics. It was established that foliar feeding with mineral nitrogen fertilizers (urea) contributed to an increase in barley productivity.
