Effect of baikal em-1 microbiological fertilizer on growth and development of cotton
Abstract
Abstract Level of soil salinity and water scarcity increases from year to year, it is necessary to increase the immune system of crops against diseases, pests and stressors, stable, high even in any unfavorable conditions. In the field experiment, 60-70% of the annual rate of phosphorus fertilizers, 50% of potassium was applied before autumn plowing, the rest of the rates of phosphorus fertilizers were applied together with nitrogen fertilizers during the flowering period, and potassium fertilizer was applied during the tillering period. The results showed that Baikal EM-1 (without mineral fertilizers) was sprinkled before plowing, before sowing seeds, on 3-4 true leaves, during pruning, flowering (10+10+3.0+3.5+3.5 l/ha) in the 8 variant, compared to the control variant (variant 1), the number of bolls decreased by 0.4 units, and the opening of bolls was around 30.0%.
