A field experiment was conducted during the winter (rabi) season of 1994/95 and 1995/96 in Junagadh, Gujarat, India, to study the effect of 3 drip irrigation regimes (0.4, 0.6 and 0.8 cumulative pan evaporation (CPE)), alternate furrow and surface irrigation method as main plot and 3 nitrogen levels (80, 120 and 160 kg/ha) as subplot treatments on yield and quality of winter cotton (G. hirsutum) cv. G. Cot Hybrid. Application of irrigation through drip method at 0.8 CPE recorded significantly higher growth and yield attributes, seed-cotton yield, oil content, seed and lint index than surface, alternate furrow method and drip irrigation at 0.4 CPE. The methods of irrigation did not show significant effect on fibre length, fineness and bundle strength. Drip irrigation at 0.8 CPE recorded the highest water use efficiency in winter cotton besides water saving to the extent of 15% on unit basis. Almost all the growth and yield attributes, seed-cotton yield, oil content, seed and lint index increased linearly with the increase in nitrogen level from 80 to 120 kg N/ha.
