Abstract
In this developing world, saving water is the main problem for agricultural sciences. So, in this field, scientists are using many methods to save water-for instance, traditional irrigation, drip irrigation, sprinkler irrigation, sub-irrigation, and others. Solving irrigation and the problems in this article demonstrated the sub-irrigation method for agriculture plants in the Uzbekistan regions. According to watering theory in the field condition and compared to drip irrigation in the region, scientifically experiment was done. According to the results of the study, this method will automate the stability of soil moisture in the irrigation of agricultural crops: save 4 … 5 times water and prevent soil salinization; the cost of processing plants and fuels and lubricants with the help of technical means is sharply reduced; land use coefficient increases; hardening of crop rows and the number of their processing is sharply reduced; it is guaranteed to increase crop yields by mixing the juice with water; environmental pollution and soil salinity are sharply reduced. In the case of drip irrigation of agricultural crops, flexible plastic pipes with a diameter of 16… 20 mm are laid on the soil near the crop stalks, from which water holes or cracks are formed at certain intervals, from which water drips and irrigates crops. It is also possible to mix the juice of chemical and local fertilizers with water.

Summary
In the Decree of the President of the Republic of Uzbekistan Sh.M.Mirziyoev dated July 10, 2020, No 6024 "On approval of the Concept of development of water resources of the Republic of Uzbekistan for 2020-2030", as well as on August 11, 2020 "On efficient use of water resources and land management in Jizzakh and Syrdarya regions. Resolution No 4801 "On urgent measures to improve the reclamation status" reiterated the need to develop water-saving technologies. Given the shortage of water in Central Asian countries, it requires water-saving technologies for the irrigation of agricultural crops. Water-saving technologies include irrigation of agricultural crops on film, rain, drip, and subsoil. The article presents the technical and technological solutions for wet irrigation of agricultural crops, the diameter of the pipe, the depth and slope of the pipe, the distance between the pipes, water pressure indicators are determined by field experiments, and the technology of its application
