Abstract
Iirrigation soil moisture of winter wheat varieties "Tanya", "Vershina", "Kalym", "Andijan-4" in conditions of meadow soils of Andijan region compared to limited field moisture capacity (ChDNS) 70-70-70%,75-75-75% and maintained at 80-80-80%. Irrigation soil moisture relative to limited field moisture capacity (ChDNS) 75-75-75% in the specified variants of the above varieties of winter wheat compared to other irrigation options (ChDNS
70-70-70%, 80- 80-80%) formation of high yield elements was determined. Among the studied varieties of winter wheat, the "Kalym" variety, which belongs to foreign varieties, is considered acceptable ChDNS 75-75-75% irrigation option spike length (cm), number of grains in one ear (grains), weight of grains in one ear (g), weight of 1000 grains (g) showed high results and was found to be 8.8 cm, 45.8 pieces, 1.46 g, 42.4 g, respectively. When analyzing the grain and straw yield of winter wheat depending on the irrigation methods, the "Vershina" variety belonging to foreign varieties has the highest grain yield of 69.5 t/ha, soil moisture before irrigation is 80-80-80% in the irrigation option of 82.4 ts/ha was determined to form a straw crop.
