Irrigation and Melioration

Abstract

There are given the results the adaptation method of irrigation norms in cotton’s Penmana-Monteyna (FAD-56) in a conditions of arid climate in Uzbekistan. It sets measure of compliance estimated in irrigation of cotton sort Navruz in an open and straw mulching wheat and perforated polyethylene slick for furrow. The difference between calculated and practical values of the irrigation rate was: on open furrows with water supply through the aisles under irrigation (in 50 % furrows ) 8.3 % also, by furrows straw mulch under irrigation 13.5 % also, by furrows slick mulch under irrigation 8,3 % . On the average, 3 variants of the difference was 10 %.
