ABSTRACT
The article describes the microbiological preparation of Zamin-M 2.0 before sowing seeds; 2.5 and 3.0 l / t, applied at a rate of 2.0 l / ha during the budding and flowering periods of cotton, provided data on the effect of increased seed germination and cotton yield. It was found that the germination rate of seeds in the variants treated with the microbiological preparation Zamin-M increased by 10.9-14.1% compared to the control variant, and 7.9% higher in the variant treated with Baikal EM 1.
KEY-WORDSCotton, seeds, stimulants, forgetfulness, growth, development, cotton yield.
