A field experiment comprising of four irrigation levels (drip irrigation at 0.6, 0.80 and 1.0 of ET0 and surface irrigation) and three fertilizer levels (125, 100 and 75% of RDF) was conducted during rabi season of 2019-2020 in a sandy loam soil on cabbage. The results showed that drip irrigation at 1.0 ET0 with 125% RDF registered the tallest plant (18.96 cm), highest number of leaves (15.63), leaf area per plant (3052.67 cm2), LAI (2.04), diameter of head (13.45 cm), fresh weight of head (980.21 g) and maximum head yield (586.34 q/ha) which was competitive with drip irrigation at 1.0 ET0 with 100% RDF and drip irrigation at 0.8 ET0 with 125 and 100% RDF. Lowest growth, yield components and yield were recorded in surface irrigation with 75% RDF. Maximum CWUE and FUE was found with drip irrigation at 0.6 ET0 with 125% RDF. Drip irrigation levels saved 64.8-41.3% water as compared with surface irrigation which could bring another 77.3-43.0% area under drip irrigation. Highest yield of 55.9 t/ha was predicted with ETa at 128 mm and irrigation at 73 mm. Ky was estimated as 2.245 (R2= 0.84). Based on higher yield, CWUE, FUE and water saving, drip irrigation at 0.8 ET0 with 100% RDF was found to be the best treatment combination which may be advocated to the farmers of the Indo-Gangetic plains.
