Past investigate set up application of wrinkle water system to create growth-stage-specific water system planning for upland cotton (Gossypium hirsutum L.) in Uzbekistan. The paper presents encourage examination of water system planning for two cotton assortments and its impact on seed-lint abdicate and water system trim water efficiency beneath wrinkle and trickle water system innovation. Field experiments were conducted in silt loam soils of Samarkand province, Uzbekistan, in 2019, 2020, and 2021. The development stages of germination to blooming, blossoming to boll arrangement, and development were considered for the improvement of water system planning Fc with regard to field capacity (Fc). The best growth, development and seed-lint yield for the C-8286 cotton variety were achieved in drip irrigation with irrigation scheduling of 75-75-70% of Fc, wetting front layer of 50-70-50 cm where the seed-lint yield totaled 4.99 t ha-1. The highest seed-lint yield (4.74 t ha-1) obtained in irrigation scheduling of 70-70-60% Fc regarding Bukhara-102 variety. Irrigation scheduling of 75-75-70% Fc for cotton variety C-8286 and 70-70-60% Fc for Bukhara-102 variety and drip irrigation should be considered applicable practices for both aforementioned cotton varieties on silt loam soils of Samarkand province and for similar soil-climatic conditions of Central Asia.

“…Along the length of the filter (filter frame), sanding wells are covered with soil by 20-80 percent, depending on the amount of silting and the service life. The process of sanding water wells is a problem in different areas in different parts of the world [13][14][15][16].…”

The history of vertical drainage wells began in 1923 in the United States of America and since 1950 in Uzbekistan. Such scientific researchers as N. Reshetkina, Kh. Yakubov, A Umarov, Z. Pushkarev, N. Nasonov, I. Akhmedov, and other scientists worked on designing and constructing vertical drainage wells. The study aims to develop recommendations for improving the sustainable operation of vertical drainage wells based on their design and construction, considering natural and economic conditions. The relevance of the work lies in the fact that stable operation of wells without sanding will provide: an increase in the duration of good operation without repair, an improvement in water supply in the reclaimed area, drainage of the area suspended on the well, and an increase in economic efficiency. The place of research work is the Syrdarya and Fergana regions of the Republic of Uzbekistan, as well as the Kyzylorda region of the Republic of Kazakhstan. The design of vertical drainage wells differs significantly from water wells (for water supply) in that vertical drainage wells are drilled with a large diameter (800-1260mm) and equipped with gravel filters. They have a shallow depth (35-80m) and large diameters of the filter frame and casing pipe (300-426mm), which significantly affect their costs and determine the territory's drainage area, which is the main task of this type of well. Such wells are operated in the study areas. The article presents data that is the basis for developing recommendations for improving the sustainable operation of a vertical drainage well. Recommendations are given to eliminate the problems of vertical drainage wells.

“…According to research conducted by Kevin Bronson in the irrigated lands of Texas and Arizona in the southwestern regions of the United States, Internal Nitrogen Use Efficiency (iNUE) is the most important factor in increasing fiber yield. It was determined that the average nitrogen application was 91 and 133 kg per hectare, the fiber yield was 1535 and 1790 kg, and the average nitrogen uptake was 128 and 177 kg ha -1 [7][8][9][10][11][12][13][14][15].…”

Prior studies have demonstrated that using furrow irrigation to develop the growing stage of upland cotton in Uzbekistan dictates when to schedule irrigation. The paper presents additional research on cotton irrigation timing variety C-8286 and how it affects irrigation crop water productivity and seed-lint yield as well as new fertilizer application technology under furrow and drip irrigation technology. Field research was carried out in silt loam soils of Samarkand province, Uzbekistan, in 2021 and 2022. When developing the irrigation schedule Fc with regard to field water content capacity (Fc), the stages of development from germination to blooming and from blooming to boll creation, and maturity were taken into consideration. The optimal development, growth, and output of seed lint for the. C-8286 cotton variety were achieved in drip irrigation technology with irrigation scheduling of 75-75-70% of Fc, wetting front layer of 50-50-50 cm during the abovementioned three growth stages, respectively where the seed-lint yield totaled 5.20 t ha-1. Irrigation scheduling of 75-75-70% Fc for cotton variety C-8286 and drip irrigation ought to be regarded as appropriate procedures for both aforementioned types of cotton grown on silt loam soils in Samarkand province and for comparable soil-climatic circumstances of Uzbekistan and Central Asia.
