EFFICIENCY OF FERTILIZERS AND PLANT GROWTH STIMULANTS ON MALTING BARLEY CROPS

Abstract

Analysis of economic indicators of the experiment in which the effect of precursors and fertilizers were studied, showed that a high level of profitability was recorded in the experiments, which were placed after sugar beet and on which «Nutrivant Plus malting barley» (71.8%) was used. In the part of the experiment, where the predecessor was the maize on grain, the best effect has also been achieved on the variants on which a complete fertilizer was applied. Application of «Nutrivant Plus malting barley» can significantly reduce the cost of production compared to the control without fertilizer and options using N30P30K30. Effective use of growth stimulators was mainly in cases where the plants were fertilized with «Nutrivant». The best results were achieved by using drugs «Nano Gro» and «Vitazim». Application of growth stimulators can increase performance of profitability and net income almost twice, but the action of drugs is largely corrected by the selected system of fertilizing crops. On crops of barley, which are fertilized with mineral fertilizers, it is advisable to use drugs «Vitazim» and «Nano Gro».
