Optimization of energy costs in the production of winter wheat

Coefficient of bioenergy efficiency of total energy consumption for intensive technology of winter wheat cultivation has been determined. Optimal values of yield and total energy consumption have been obtained, considering current climatic conditions of the year. The maximum difference in the yield level depending on conditions of the year of cultivation was 5 c/ha with a total energy consumption of 35 GJ/ha. Additional costs of material and technical resources do not lead to an increase in grain yield of winter wheat. With climatic conditions, this pattern persists, including an average of three years. According to research, the extreme value of the bioenergy efficiency coefficient occurs in middle years at the same level of energy consumption as for grain yield, while further growth in the level of intensification of cultivation technology reduces the efficiency indicator. In other years of wheat cultivation, proportional decrease in the coefficient with increasing energy consumption is observable.
