IRRIGATION BY GROUNDWATER AT THE EXPERIMENTAL AREA IN THE KUVINSKY DISTRICT OF THE FERGANA REGION

Abstract

The article talks about the rational use of water pumped out of vertical drainage wells. The solution to the problem is determined by irrigation with water from vertical drainage wells, without dumping them into the collector-drainage network. An example of irrigation is given on the experimental plot of the Kuva region, the farm "Musazhon Ismoilov". The compiled water-salt balances of the reclaimed lands for the experimental period showed that in the incoming part the main role is played by water supply and filtration from canals and atmospheric precipitation. In the consumable part, the main place is occupied by evapotranspiration and drainage flow. In the experiments, cotton of the S-6524 variety was sown, and the agricultural technology of growing cotton was generally accepted for the farm. Sowing of cotton was carried out in the second half of April with a row spacing of 90 cm. An irrigation experiment on irrigating cotton with pumped-out water showed the possibility of using this water directly on the fields. Without dumping them into collector-drainage waters.
