Abstract

The articlepresents theresults ofgrowing cottonundertheconditions ofsalinemeadow–alluvial soils

in the Bukhara region, where the groundwater level is 2.0 - 2.5 m, using mineralized water for drip

irrigation. When the pre-irrigation soil moisture was maintained at 70 – 80 - 65% of the field capacity,

cotton was irrigated 15 times according to the 3 - 10 - 2 scheme. The crop was not irrigated during

the period from germination to flowering, while during the flowering and boll formation stages,

irrigation norms ranged from 273 to 437 m³/ha, with a total seasonal irrigation rate of 4483 m³/ha.As

a result, compared to the control variant, water savings of 1594 m³/ha were achieved.
