IRRIGATION OF COTTON BY SUB-IRRIGATION METHOD
Keywords:
sub-irrigation, irrigation, cotton, variant, soil, vegetation, drainage.Abstract
In recent years, Uzbekistan has experienced a certain deficit of irrigation water, which can largely be compensated by utilizing return, drainage, and underground waters. In the second and third variants, irrigation amounted to 900 m³/ha, while during cotton ripening it was 800 m³/ha. In these studied cases, the total irrigation norm was 2400 m³/ha. Cotton yield in the first variant was 31.0 c/ha, in the second variant 29.8 c/ha, and in the third variant 28.7 c/ha.
