Efficient use of canal water through drip irrigation in cotton (Gossypium hirsutum)

Abstract

A study was conducted during 2003–06 to optimally utilize the drip irrigation system already available with the orchardists of south-west Punjab wherein, adaptive research trials at farmers’ fields using drip irrigation in cotton (Gossypium hirsutum L.) with paired row planting were laid in Abohar (Ferozepur district) to see the performance of crop and compare with the farmers’ practice of applying irrigation through flooding. The average increase in yield in drip irrigated plot was 21% (with a maximum yield of 2 812 as compared to 2 036 kg/ha under flooding) with water savings of 30%, besides early maturity, labour savings and risk coverage under heavy downpour than the flooding method. The economic analysis showed that the method of using drip irrigation in cotton was technically feasible and economically viable in canal command area with a benefit cost ratio of (2.03:1) as compared to flooding (1.88:1).
