Abstract
Two varieties of cotton (Niab-78 and Niab-92) were grown under furrow and alternate furrow irrigation methods. In alternate furrow irrigation, 40.61% less water was used. Water use efficiency in both the varieties was 22 and 21% higher in alternate furrow irrigation as compared to every furrow irrigation. Variety Niab-92 gave maximum water use efficiency in both the methods. Alternate furrow irrigation received less amount of water and produced almost the same yield as in every furrow irrigation method.
