ARTICLE ANNOTATION

quote
Research was conducted in the Tashkent, Samarkand, Khorezm, and Kashkadarya regions to develop an agrotechnology for producing high-quality cotton seeds under furrow and drip irrigation systems. Under the conditions of irrigated typical sierozem soils in the Tashkent region, the cotton varieties Sultan and UzPITI-103, and under the meadow-alluvial soils of the Khorezm region, the seed cotton varieties Khorezm-150 and С-8294 (Gurlan), grown under furrow irrigation with optimal irrigation and fertilization regimes, increased seed cotton yield by 3.5–4.5 centners per hectare (0.35–0.45 t/ha). Furthermore, the use of the modern Wetting Front Detector (WFD) for irrigation scheduling reduced irrigation water consumption by 10–15%. In the Samarkand region, an agrotechnology for producing high-quality cotton seeds under drip irrigation was developed. It was scientifically demonstrated that, for early-maturing medium-fiber cotton varieties, seed cotton can be harvested from the 3rd to the 9th fruiting branches, increasing the proportion of seed cotton in the total yield from 46.4% to 51.5%. Under the meadow-takyric soils of the Kashkadarya region, it was determined that maintaining pre-irrigation soil moisture at 70–75–65% of field capacity (FC) and applying fertilizers at the rates of N–250, P–175, and K–125 kg/ha are optimal for the fine-fiber cotton varieties Termiz-202 and Surkhon-16. This practice increased seed cotton yield by 4.7–6.6 centners per hectare (0.47–0.66 t/ha).
