Abstract

To justify the energy efficiency of ten-field crop rotation depending on the system of fertilization and tillage, energy output with the crop and energy costs.

The measure of the energy efficiency of crop cultivation is the energy efficiency ratio, which expresses the ratio of the total energy content of the cultivated product in the amount of non-renewable energy expended on its cultivation.

The results of studies that were carried out in a stationary experiment on typical deep chernozem in the zone of unstable moisture in a ten-crop crop rotation are presented. Studies have shown that the use of compost 4.5 t + N80P96K108 energy output with a yield in the fertilizer system reached 134.6 GJ / ha, organically mineral for applying compost 4.5 t + N40P48K54 + 3.5 t by-product and green manure weight - 129.0 GJ / ha, which is 107 and 98.4%, respectively, higher than that of an uncomfortable background. The coefficient of energy efficiency (Ke) was the highest with an uncomfortable background - 7.3, for organo-mineral - 6.9, mineral - 6.1. High rates of fertilizer applied to the options of experience, increase energy output with the crop. Reducing the rate of fertilizer significantly reduces both energy output with yield and energy efficiency ratio.

The highest energy yield with a yield of 134.6 GJ/ha was recorded by the mineral fertilizer system. Plowing on the organo-mineral system fertilizer of crop residues of all crops and sideral mass provides energy output with a yield of 129 GJ/ha with Kee 6.9, which significantly exceeds the control. Reducing the rate of fertilizer significantly reduces both energy yield and yield, and energy efficiency ratio.
