Effect of sowing date, scheme and nutritional conditions on glycine height grown for grain

The article presents the results of the research conducted on the influence of cultivation factors on the growth of the Biyson variety of soybeans in 2018-2020 in the Absheron region to obtain the grain harvest. In the studies, when the optimal sowing period of soybean was carried out in the 3rd decade of April, in all three sowing schemes, the highest indicator of the height of the plant was at the N60P40+15 tons of manure option. At the mentioned version, the height of the plant, depending on the sowing scheme, was 2.8-4.4 cm at the stage of 4-5 true leaves, 6.2-11.1 at the stage of branching, 4.9-15.9 cm at the stage of budding-flowering, 4.2-14.4 cm in pod formation stage and at the full maturity stage, it was 5.6-26.3 cm taller than the non-fertilized version. This has created conditions for more branching of the plant and the formation of beans, which, in turn, have a substantial effect on the increase in productivity.
