THE ECONOMY OF WATER RESOURCES WITH THE USE OF POLYMER COMPLEXES IN IRRIGATION OF A COTTON

The article deals with the use of polymer complexes in alluvial-meadow soils under the pre-determined humidity of 70-80-65% of the maximum field moisture capacity, in the second option with the 1-2-1 scheme in the Bukhara oasis. During the seedling and flowering phase, one irrigation irrigation norm was performed at 734 m3/ha; during the blooming and fruit cultivation phase, three irrigation operations were performed with irrigation norms of 631-644 m3/ha, one irrigation with a watering rate of 865 m3/ha was performed during the maturation phase. The irrigation norm was 2874 m3/ha or, relative to the control variant, by 1754 m3/ha less, which allowed saving manual water, as well as the results of the conducted experiments and their impact on cotton growth, development and yield.
