Protein is the most valuable part of the human diet. Soybean is the most promising plant in the world and ranks first in the biologization of agriculture. Soybean is the main and leading plant in providing food and feed protein in world agriculture. Research work was carried out in 2019-2021 on the experimental site of the institute of bio-resources of the Nakhchivan Branch of Nanazerbaijan. 31 soybean varieties brought by us from the institute of genetic resources of ANAS and the scientific research agricultural institute belong to different ecological groups. From these samples, the Bravo variety was taken, which is suitable both in terms of its productivity and the soil and climatic conditions of the autonomous republic. Various doses of nitrogen fertilizers were applied (Control without fertilizer, organic fertilizer 10 t/ha+P60K60 (Background), background +N30, background +N60, background +N90) for crops with a sowing period of April 20, with a planting pattern of 70 × 10 cm. Thus, it can be concluded that at the time of sowing, in the experiments conducted on April 20 and the sowing scheme of 70 × 10 cm, the yield of protein and fat was high, depending on the amount of protein and fat. Thus, as a result of the research, the most productive variety Bravo was determined in the conditions of the autonomous republic, either according to the planting period or the planting scheme, and after applying different fertilizer rates, the quality indicators were: When comparing all three planting schemes, the highest results were obtained with a planting scheme of 70 × 10 cm and a fertilizer rate of Fon +N60. In the experiments conducted on April 20, quality products (protein, fat, fiber, moisture) and fat was highest at a planting pattern of 70 × 10 cm and a normal fertilizer background +N60; protein 39.74-39.98%, fat 18.9-19.09%, fiber 6.69-7.18%, humidity 5.21-5.78%, protein yield composition 1084.9-1179.4 kg/ha, and the fat yield is 515.7-563.2 kg/ha.
