EVALUATION OF THE EFFECTIVENESS OF FERTILIZATION SYSTEMS OF SPRING BARLEY DEPENDING ON THE PURPOSE OF GRAIN
Abstract
Studies were conducted on sod-podzolic light loamy soil with a very high content of mobile compounds of phosphorus and potassium. The influence of various fertilizer systems on the productivity of spring barley with a differentiated approach to the calculation of their economic efficiency, taking into account the purpose of the grain is studied. The application of N60R20K45 on an organic background ensures the formation of barley grain with a profit level of 212 USD/ha with a profitability of 193 % is established. Application of N90+30P20K45 on an organic background is provides forage grain formation with a profitability level of 80 % and 127 USD/ha profit.
