Influence of Nitrogen, Phosphorous, Potassium Fertilizers and Inoculants on Formation of Vegetative Organs, Amount of Nodules and Yield of Soybean Cultivars

Abstract

In the article, the results of experiments on the effect of different inoculants on the development of soybean growth, yield, grain quality, and the amount of nitrogen, phosphorus, and potassium in the vegetative organs of the plant during the podding phase, when the new Es-mentor varieties of soybeans created in Krasnodar regions and the local Orzu were planted as a repeat crop after the autumn wheat harvest stated. Bradyrhizobium japonicum Bacillus subtilis BS-26 created in our republic in the conditions of irrigated typical gray sierozem soils of Tashkent region and complex inoculant imported from the Russian Federation contains 3-Ligabak pronok (Bradyrhizobium japonicum (109), Bradyrhizobium diazoefficiens (USDA110), Bradyrhizobium elkanii (E123)+0.5% molybdenum. The results of the study on the effect of the added bacteria on the yield and quality of the soybeans were analyzed in the section of experimental options. The soybean varieties were planted at a rate of 700,000 seeds/ha with a row spacing of 70 cm. Es-mentor variety (1000 1000 seed mass 190 g) 103 kg/ha,Orzu variety (1000 seed mass 130 g) 91 kg/ha of seeds were used, the difference in seed consumption in kilograms was caused by the difference in the mass of 1000 seeds, the number of seeds sown was the same in both varieties. 700 thousand seeds/ha effected the results of the experiment on the quality of the harvest are described.
