Abstract
The article presents studies in the agrocenoses of winter wheat conducted in the conditions of the Ryazan region on dark gray forest soils. The productivity of varieties of winter grain crops – Moskovskaya 56, Ethane and their reaction to the application of organic fertilizers has been studied. When applying manure at the rate of 15 t/ha (the standard dose used in the farm), the yield increase averaged +3.8 c/ha (45.8 c/ha) for the Moskovskaya 56 variety, +4.9 c/ha (46.9 c/ha) – Ethane grade, to control (Moskovskaya grade 56, without applying organic fertilizers). The maximum increase in wheat grain was detected in the variants with the introduction of manure of 29 t/ha, where the increase in control was 56 – 11.9 c/ha (51.9 c/ha) for the Moskovskaya variety, 13.5 c/ha (53.5 c/ha) for the Ethane variety.
