Economy Of Water Resources In Irrigation Of A Cotton With The Use Of Polymeric Complexes

In the article, the use of polymer complexes in alluvial–meadow soils under 70–80–65% pre-moisture from the marginal moisture capacity is considered, in the second variant with the 1–2–1 irrigation scheme. In the seedling and flowering phase, one irrigation with a norm of 734 m3/ha was carried out, in the blossoming and fruit cultivation phase, three waterings were carried out with the norms of 631–644 m3/ha, in the maturation phase, one irrigation with an irrigation rate of 865 m3/ha was carried out. The irrigation norm was 2874 m3/ha or, with respect to the option, a control of 1754 m3/ha less, which allowed saving irrigation water, as well as the results of the conducted experiments and their impact on cotton growth, development and yield.
