This study was conducted at Horticulture Farm, Rajasthan College of Agriculture, MPUAT, Udaipur during the summer season in 2013-14 and 2014-15. The experiment consisted of 15 treatment combinations replicated three times which included 3 levels of irrigation viz., 80%, 60% and 40% PE through drip irrigation and five levels of fertigation viz., 100% RDF, 75% RDF, 50% RDF, 75% RDF + 2 foliar spray 1% urea phosphate, and 50% RDF + 2 foliar spray 1% urea phosphate through fertigation. Results showed that maximum fruit weight (3.73 g) and fruit yield ha-1 (16.13 t), nutrients uptake, net return and B: C ratio were recorded with 80% PE through drip irrigation over 40% PE. Similarly the highest fruit weight fruit-1(3.72 g), average yield weight plant-1 (261.00 g) fruit yield plot-1 (47.34 kg), fruit yield ha-1 (15.94 t), nutrients uptake, net return and B: C ratio of chilli were obtained under treatment with 75% RDF through fertigation + 2 foliar spray 1% urea phosphate over 50 per cent RDF through fertigation. Highest water use efficiency was found under drip irrigation at 40 % PE (4.18 q ha-1 cm) over 60% PE and 80% PE. It was further concluded the application of 75% RDF through fertigation + 2 foliar spray 1% urea phosphates gave highest water use efficiency (3.26 q ha-1 cm) than other treatments.
