Yield of soybeans depending on primary soil tillage and organic fertilizer aftereffect

Abstract

Studies were conducted on an experimental field of Samara State Agrarian University in 20072019 with the purpose of studying the influence of primary soil tillage of typical heavy loam chernozem and aftereffect of different organic fertilizers on the yield of soybeans. The most optimal conditions for the soil density were determined by plowing, which was 0.90-1.10 g / cm3 for the growth and development of soybeans. Primary tillage did not have any significant effect on the productive moisture reserves in the meter layer of soil. Shallow tillage and no-till contributed to a 1.3-time increase in weediness of soybean crops compared to plowing. The greatest crop yield 1.45 t / ha was collected by plowing, which was 0.25 and 0.44 t / ha higher than by shallow tillage and no-till respectively. The aftereffect of organic fertilizers promoted the additional soybean yield of 0.17-0.18 t / ha compared to the non-fertilized plot. New types of organic fertilizers were as good as manure in terms of impact on productivity.
