    Abstract: Keeping up 12-15 cm layer of water in a rice
draught in the post-tilling to waxen ripeness does not
provide a favorable thermal and saline soil and water
regimes. Temperature regime of water in a rice draught is
determined by climatic conditions of the region and the
depth of water on crops. In conditions of extreme
continental climate of Syr-Darya water layer at a depth of
12-15 cm in the water warms up the draught 31,0 - 32,5°C
which negatively affects the growth and development of
rice plants and its yield. Favorable thermal regime of
water is observed at a depth of 17-22 cm and here we
have the necessary salt regime of irrigated soils.
Therefore, maintaining the draught in paddy water layer
depth of 17-22 cm provides favorable salt and thermal
regimes of water and soil.
