Abstract

It was taken into account that the yield of cotton grown in conditions where the irrigation regime is 70-70-60% relative to the limited field moisture capacity of the soil (LFMCS) is higher than in the years of experiments compared to the yield in the 75-75-60% regime.

In the 70-70-60% irrigation regime, the average yield was 35.4-40.5 ts/ha, depending on the thickness of the bush and the ratio of fertilizers, while in the 75-75-60% irrigation regime the yield was 33.5-36.5 on average ts/ha.

It was found that the micronaire value of fiber in cotton harvested from experimental variants was 4.3-4.5, which is slightly higher than the micronaire index of cotton fiber harvested from 70-70-60% of irrigated variants compared to 75-75-60% irrigation regime.
