The article examines the effect of different water thicknesses on economic efficiency in the cultivation ofnrice varieties. Different thicknesses of water affected the development periods of rice. With the increase in the thickness of the water, depending on the varieties of rice, the development period was extended from 2 to 3-4 days.The highest yield was obtained when the water depth was 15 cm. The increase and decrease of water thickness has been observed to decrease the yield of rice
