Popis: | The global climate changes and their influence on agriculture in Uzbekistan were analyzed, including problems of irrigation water shortage on irrigated lands in the lower reaches of the Amu Darya with the greatest water shortage due to repeated dry years. Additionally, the recommendations for the effective use of water resources in the conditions of meadow alluvial soils salinization and shallow salinized groundwater were proposed to use subirrigation and drip irrigation to irrigate cotton, maintaining the pre-irrigation soil moisture of the lowest soil moisture capacity. The introduction of a science-based regime for cotton using subirrigation and drip irrigation methods provides conservation of water up to 1.596–1.757 (subirrigation) and 1.596–1.757 (drip irrigation) cbm/ha, an increase in cotton yield of up to 6.3 centner/ha. |
