Abstract
Abstract Sowing is the most important agrotechnical operation, on which the yield directly depends. With the nested method of sowing soybeans, better illumination is achieved, thanks to which plants develop the root system and aboveground parts better, which contributes to a high attachment of the lower beans on plants and reduces losses during harvesting. A seeding apparatus for nest sowing has been designed and manufactured, taking into account the physical and mechanical properties and dimensional characteristics of soybean seeds. Field studies of the nested method of sowing soybeans were carried out in the farm “Niva” of the Tambov region, according to the results of which, taking into account the humidity and weight of 1000 seeds, the biological yield was calculated. With the nested method of sowing. on the experimental plot, a yield of more than 4 t/ha was obtained, which is 0.4% more than with continuous sowing on the control plot, despite the 2-fold increased seeding rate on it. The height of attachment of the lower beans on the plants of the experimental plot averaged 15 cm, on the control plot the height of attachment of the lower beans was 10 cm.
