BIOENERGY INDICATORS OF GROWING CORN FOR GRAIN
2020
Garmashov, V.M. | Kornilov, I.M. | Nuzhnaya, N.A.
The maximum yield of corn for grain was obtained by deep dump processing at 25- 27 cm (recommended in the zone for row crops) against the background of mineral fertilizers (6.42 t /ha) and without them (5.90 t/ha). On average, processing (regardless of background fertilization) received 6.16 t / ha of grain culture. The use of small, surface and zero treatments for crops reduced the yield level by 12.1-66.4%, with the minimum values for the variant without soil treatment. The use of mineral fertilizers increased the yield of corn for grain from 0.25 t / ha (zero processing) to 0.58 t / ha (with a combined system of processing in the crop rotation). The greatest accumulation of total energy in corn grain on the background of the application of mineral fertilizers was noted for deep dump processing, respectively, 89.3 and 97.2 GJ / ha, with a maximum coefficient for small dump processing on the background of fertilizer application - 6.52 and without them - 8.21, which is largely associated with a decrease in the cost of grain production.
