THE INFLUENCE OF THE TIME OF BASIC TILLAGE AND FERTILIZATION ON SOYBEAN YIELD

Abstract

The time of basic tillage and fertilization are very important agrotechnical measures that have a high impact on soybean yield. Winter basic tillage of the soil reduces the harvest yield by 8.53%, and spring tillage by 21.18%, the application of NPK fertilizers increased the yield by 13.96%, the foliar application of water extract from plant material by 9.57% and the application of AN by 8.44%. Autumn basic tillage is most conducive to achieving high and stable soybean yields, and fertilization has a positive effect on soybean yields.
