Abstract

Field experiments Cotton is grown on meadow-alluvial soils (87.7%), which make up the largest area of irrigated lands in the Bukhara region, and in conditions of a depth of groundwater of 1.5-2.0 m. Development and productivity have been studied. The
farm soil is moderately saline. The irrigation scheme was determined by the criteria,timing and amount of irrigation, as well as the criteria of seasonal irrigation,depending on the level of soil moisture and specific climatic characteristics. In the experimental field sown with cotton, according to option 2, a black film was applied to the field with a moisture content of 70-80-65% in relation to the field moisture. The cotton yield was 15.0 kg / ha higher. traditional option 1.
