Abstract

Purpose. Medium-fiber "Andijan-36" and "Navroz" cotton on the background of repeated crops (mushroom and soybean) grown in different rates of mineral fertilizers in light gray soil of Andijan region is to develop optimal agro-measures for the cultivation of quality seeds from varieties. Also, the degree of germination of seeds of these cotton varieties under field conditions was studied in all variants and returns of experiments.


Methods. In our experiments, soil samples, phenological observations, agrochemical, technological analyzes in laboratory, field and production tests are adopted in UzPITI "Methods of Conducting Field Experiments".


Results. In the experiment, after winter wheat, mush plants were grown on the background of mineral fertilizers N-25, P2O5-80, K2O-60 kg/ha, and the seeds of the Andijan-36 variety at the end of the observation period according to repetitions 88 ,1; 86.1; 89.2% germinated on average 87.8%, while Navroz variety had 88.1; 84.1; It was 88.8 and 87.0%.


Summary. It is necessary to apply mineral fertilizers at acceptable rates even in repeated crops for the optimal growth and development of medium fiber Andijan-36 and Navroz varieties of cotton in the conditions of light gray soils. , and it was found that the effect after these plants is good.
