Energy efficiency of winter rapeseed cultivation depending on the technology elements

Abstract

The results of studies on the effect of planting time and various rates of mineral fertilizers on the formation of indices of energy efficiency of winter rapeseed hybrids of various maturity groups are analyzed. The significant influence of the technology elements studied on the main indices has been noted. It has been established that a change in the yield rate obtained by hybrids caused a change in the energy efficiency indices. Among the three hybrids studied, the highest energy capacity of 77,900 MJ was obtained by hybrid ‘Exotic’ under the first planting time on August 10 and application of N240P120K240, the maximum energy efficiency ratio of 2.34 was obtained by hybrid ‘Exagon’ under the first planting time, but in the variant without application of fertilizers.
