Field investigations were carried out at Agricultural College and Research Institute, Madurai during summer 2004 and winter 2004-05 to find out the effect of drip irrigation and fertigation regimes on nutrient uptake, nitrogen and water use efficiency and seed cotton yield of cotton. Drip irrigation regimes with wetted area fraction (WAF), 0.5:1.0:0.6 (I4), 0.5:1.0:0.8 (I5) and 0.5:1.0:1.0 (I6) recorded increased N, P and K uptake by cotton and nitrogen and water use efficiency by cotton crop compared to drip irrigation regimes with WAF, 0.25:0.75:0.6 (I1), 0.25:0.75:0.8 (I2) and 0.25:0.75:1.0 (I3). The drip irrigation regime, I4 recorded the highest yield of 1402 kg/ha which was on par with the drip irrigation regimes, I5 and I6. The fertigation regimes of 10 equal (F1) or 10 unequal splits (F2) of N and K upto 120 DAS resulted in more sympodia, more bolls and heavier bolls and produced increased seed cotton yield.
