Treatment comprised of irrigation methods in main plot (Drip, Ridges and furrow and Sprinkler each at 50 per cent depletion of available soil moisture-DASM), genotypes in sub plot (cv. Cuddapah and cv. Pratibha and graded levels of fertilizer in sub-sub plot (180:90:90, 225:112.5:135 and 270:135:180 kg N:P2O5:K2O ha-1) with one control (Furrow irrigation at weekly interval with cv. Cuddapah and application of 180:90:90 kg N:P2O5:K2O ha-1). Drip irrigation at 50 per cent DASM recorded significantly higher cured finger rhizomes (3.67 t ha-1) and curcumin yield (188.2 kg ha-1) and water use efficiency (WUE) of 258.5 kg ha-cm-1 with water saving of 31.6 per cent over control. Cudappah variety was superior over cv. Pratibha in cured finger rhizomes yield (3.59 t ha-1). Pratibha variety resulted in higher curcumin content (6.30 %) and curcumin yield (201.1 kg ha-1). Application of 270:135:180 kg N:P2O5:K2O ha-1 resulted in higher cured finger rhizomes (3.51 t ha-1) and curcumin yield (178.5 kg ha-1) which was on par with 225:112.5:135 kg N:P2O5:K2O ha-1. Drip irrigation at 50 per cent DASM with cv. Cudappah and 270:135:180 kg N:P2O5:K2O ha-1 recorded significantly higher cured finger rhizomes yield (4.07 t ha-1) and WUE (282.4 kg ha-cm-1). Drip irrigation at 50 per cent DASM with cv. Pratibha and 270:135:180 kg N:P2O5:K2O ha-1 recorded higher curcumin yield (241.5 kg ha-1), B-C ratio (2.71) and net return ( 2.83 lakh ha-1) which was on par with drip irrigation at 50 per cent DASM with 225:112.5:135 kg N:P2O5:K2O ha-1 cv. Pratibha and cv. Cudappah. Results indicated that irrespective of the varieties, drip irrigation with application of 225:112.5:135 kg N:P2O5:K2O ha-1 resulted in higher yield and economics.EnglishThesis
