DETERMINATION OF RULES FOR IRRIGATION WHEN GROWING CORN (SILAGE) WITH WASTEWATER

Abstract

Over the course of 2 years, scientific and practical research was carried out to develop a regime (standard) for irrigation of the corn crop (silage) with wastewater from the city of Bukhara and the results obtained were highlighted. When the soil moisture before irrigation is 70-70% relative to the maximum field moisture capacity, seasonal irrigation in meadow-alluvial soils is 2725 m3/ha in the first year, the number of irrigations is 4 times, in the second year it is 2725 m3/ha. seasonal irrigation norm is 3358 m3/ha, and the number of irrigations is 5 times. Soil moisture before irrigation was 70-80% relative to the maximum field moisture capacity. In the first stagnant year, the seasonal irrigation norm was 2816 m3/ha. , the number of irrigations is 5 times, in the second year the seasonal irrigation norm is 3449 m3/ha, and the number of irrigations is 6 times.
