The experiment conducted at Water Technology Centre during rabi -2009-10. Experiment consisted of four irrigation with three fertigation levels. Results revealed drip irrigation scheduling irrigation at 100 % Epan realized higher green pod yield (3556 kg ha-1) which was 9.5% and 22% higher than the irrigation scheduling at 80% and 60% Epan,. However, the increase in the yield with 100 kg ha-1 N and K was to the tune of 14 and 21 % than application of 50 kg N + 50 kg K2O ha-1 and no fertilizer application, respectively. Total nutrient uptake of N,P and K was higher with drip irrigation scheduling at 100% E pan when compared to other irrigation levels. However, application of optimum dose of fertilizers 100: 100 kg ha-1 N and K through drip resulted in maximum uptake of nutrients at all the stages at 30,60 and 90 DAS compare to other fertigation levels.
