“…According to reliable sources, the plant receives 5.5.5 kg of nitrogen, 2 to 2.5 kg of phosphorus and 5-6 kg of cotton. Due to the violation of the ecological situation, the demand for mineral fertilizers throughout the years, as well as a nitrogen demand for nitrogen is between 69% (1970) [9,10], phosphorus consumption is from 42% to 48% and comparison the use of potassium in the stage increased 35 kg per hectare to 100 kg.…”

Research is being conducted around the world to develop technologies for saving and efficient use of irrigation water in the irrigation of agricultural crops. In this regard, special attention is paid to the efficient use of irrigation water, improvement of irrigation techniques and technologies, introduction of modern methods of irrigation, reduction of infiltration and filtration processes in irrigation of cotton, development of methods to retain more soil moisture and justification of irrigation regimes. Nowadays, some results have been achieved based on the research conducted by the above scientists, but insufficient research has been conducted on the effectiveness of discrete irrigation technology for cotton in screen fields formed by interpolymer complexes in typical gray soils of Tashkent region. and methods have been developed to reduce inefficient consumption of mineral fertilizers.

“…To further define the symbols "A" and "m" in the formula, it is necessary to observe in the calculation the numerical equality of each consumption symbol or consumption interval indicator with the experimental indicator. If the interval at one expenditure is greater than the experimental values but less for other intervals, they are taken into account in the calculation as an exception, and they are equalized at the expense of the auxiliary table [7][8][9][10][11][12][13].…”

The country's water supply depends mainly on the water resources of the Amudarya and Syrdarya. 80,7 % of the country's water resources are formed in the Kyrgyz Republic and Tajikistan territory. The population of Central Asia is expected to increase by 40 % in the next 20 years. This, in turn, requires more economical use of water and land resources. At present, it is important to modernize irrigation systems, increase their efficiency, automate water distribution processes, and improve the distribution of water to consumers by accurate measurement of internal channels.

“…The technical condition of the closed and requiring drainage reconstruction in the region as of January 1, 2019, in the administrative regions is given in Table 1. The calculation of horizontal drainage consists of establishing the depth of the drainage, determining the inter-drainage distances, and the drainage module (l/s) from one ha of the drainage area [12][13][14][15][16].…”

The article is devoted to the reconstruction of existing old drainage systems in order to radically improve the reclamation ecological and sanitary conditions of the lands of the Jizzakh region to improve the social conditions of the population and obtain high stable yields of cotton and other agricultural crops. As a result of many years of theoretical and irrigation to experimental research, operational monitoring in farms in the Pakhtakor district of Jizzakh region. The parameters of the primary horizontal drain are determined based on the analysis of reclamation climatic, soil, geological, hydrogeological, hydrological, economic, and other conditions. The calculation of the reconstruction of horizontal closed drainage is based on the method of A.N. Kostyakov in intensity from working the groundwater level after flushing. The depth of the drainage was determined, taking into account global climate change in recent years; based on these changes, an adjustment was made in the calculations to determine the value of the critical depths of groundwater during the operation of drainage systems. The incoming and outgoing parts of the water balance of the experimental plots were determined. In the presence of pressure groundwater, the size of the supply of groundwater with pressure water is determined. More proposed by the V.N. Shestakov's formula.
