The methodology for calculating the regimes of cotton irrigation of twoline sowing under a plastic film

Abstract

The article discusses the results of two years of experience with a semi-hydromorphic regime of soil formation in the Jizzakh region of Pakhtakor district of a new water-saving technology for irrigation of medium-ripened cotton variety Pakhtakor-1 of a two-line sowing of the irrigated drip method under a mulched dark plastic film and its comparison with the control traditional furrow method and on this basis FAO methodologies. With the new irrigation technology, the cotton yield was 42.0 c/g (irrigation norm 1630 m3/ha), and in the control 36.3 c/ha (irrigation norm 2270 m3/ha), which meets the criteria for assessing crop yields according to the MPES high experience and average on control.
