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 m<sup>3</sup>/ha was carried out, in the blossoming and fruit cultivation phase, three watering’s were carried out with the norms of 631-644 m<sup>3</sup>/ha, in the maturation phase, one irrigation with an irrigation rate of 865 m<sup>3</sup>/ha was carried out. The irrigation norm was 2874 m<sup>3</sup>/ha or, with respect to the option, a control of 1754 m<sup>3</sup>/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.
