Abstract: In the experiment, three different soil thicknesses (80; 100 and 120 thousand hectares per hectare, as well as 7.2; 9.0 and 10.8 plants per hectare), two different irrigation regimes with limited soil moisture content (ChDNS) (70). -70-60 and 75-75-60%, as well as irrigation rates 2-3-0 and 2-4-0) and two-fertilizer (NPK) ratio (1: 0.7: 0.5 and 1, respectively) Two criteria: 1: 0.5) were studied. Annual fertilizer values ??were N200 P140 and K100 and N200 R200 and K100 kg / ha. Irrigation mode was considered to be higher in the years of experiments on yields of irrigation variants of 75-75-60% than those of 70-70-60% of soil compared to ChDNS. At 70-70-60% irrigation mode, the yield was 35.4-40.5 centners / ha, depending on the thickness of the bush and the fertilizer ratio, and on the irrigation options of 75-75-60%, the average yield was 33.5-36.5. t / ha. Micronaire value of fiber in the cotton crop harvested from the experimental variants was 4.3-4.5% and slightly higher than the microneedle of cotton fiber harvested from 70-70-60% irrigation versus 75-75-60% irrigation.
Key words: Watering regime, bush thickness, fertility ratio, fertility, the quality, limited field moisture capacity, wet capacity, gross, general, mobile, nitrogen, phosphorus, potassium, humus, economic efficiency, profitability.
