Field experiments were conducted in Tamil Nadu, India, during winter (August 1998-February 1999) and summer (March-August 1999) seasons to study the water use efficiency (WUE), nitrogen use efficiency (NUE) and productivity of hybrid cotton (TCHB 213) under 2 irrigation methods (drip and furrow) and different levels and methods of nitrogen (N) application. Drip irrigation and drip fertigation substantially increased the yield attributes and seed cotton yield compared to the control. The increase in seed cotton yield in drip irrigation over furrow irrigation was 9.3 and 13.6 percent during winter and summer seasons, respectively. Drip fertigation and drip band application of N increased seed cotton yield by 10.8 and 9.7 percent in winter and 15.0 and 10.9 percent in summer, respectively, over furrow band application. Drip irrigation and drip fertigation substantially increases the WUE and NUE compared to furrow irrigation with band application in both seasons.
