Influence of the technology elements on the soybean georgia’s variety yield in the Ryazan region

Abstract

The article presents the results of two-year tests and gives a comparative assessment of the bacterial preparation and chemical disinfectants on the productivity of soybeans of the George variety. In the scheme of the experiment, the inoculant Nitragine KM was studied, SP - 0.08 kg / 1 ha seed rate and chemical preparations Tirada, SC - 2.0 l / t + Tabu, HSK - 1.0 l / t + Nitragin KM, SP - 0.08 kg / 1 ha seed rate. The studies were conducted in 2021 and 2022 at the experimental field of the institute. Soil: dark gray forest heavy loam, humus content 3.8%, mobile potassium 153 mg / kg, mobile phosphorus 226 mg / kg, pH - 4.88, exchange calcium. The predecessor is winter wheat. Determination of germination of soybean seeds showed that laboratory and field germination when using an inoculant (option 2) and chemical disinfectants + an inoculant (option 3) practically did not differ from the control variant and were at the level of 86% - 91.4%. The safety of plants for harvesting was 6.5% - 14.1% more than in the control. Two-year testing of technology elements in the cultivation of soybeans using the inoculant Nitragin KM, SP and chemical disinfectants had a positive effect on the productivity of the crop. The safety of plants for harvesting was 84.5 - 92.1%, the yield of the crop increased by 113.6 - 125.8%.
