The effect of fertilizers on the yield of hybrid winter rye on sod­podzolic sandy loam soil

Abstract

On sod-podzolic sandy loam soil, due to effective fertility, in an average of 2 years, winter rye grain hybrid KVS Vinetto 36,7 c/ha was obtained by plowing, 35,2 c/ha by disking. In the dry year 2023, grain yields were 9 % lower, and straw yields were 40 % lower than in 2022. Due to the use of fertilizers, the yield of winter rye grain on average increased by 2 times compared to the control. In the block with surface tillage, there was no significant difference in the yield of winter rye grain compared with similar variants in the block with traditional tillage, with the exception of the variant with straw treatment with microbial fertilizer Zhytsen, where the yield in the disking block was 7.6 c/ha higher than in the plowing block.

The sealing of straw without a compensating dose of nitrogen, both in traditional and surface tillage, did not have a negative effect on the uniformity of seedlings and the development of winter rye plants in the autumn period on sod-podzolic sandy loam soil.
