A field experiment was conducted to study the influence of deficit irrigation using different irrigation methods and fertilizer levels on performance of turmeric varieties at University of Agricultural Sciences, Dharwad. The experiment was laid out in split- split plot design, keeping irrigation methods (Drip, sprinkler and ridges and furrow irrigation applied as deficit irrigation at 50% depletion of soil moisture) in main plot; varieties (cv. Cudappah and cv. Pratibha) in sub plot and fertilizer levels (180:90:90, 225:112.5:135 and 270:135:180 kg N:P2O5:K2O ha-1) in sub-sub plot. Higher growth observed in terms of leaf area, chlorophyll content at 150 DAP and total dry matter production at harvest were recorded with drip irrigation. Significantly higher total fresh rhizome, fresh mother rhizomes and cured finger rhizome yield were observed in drip irrigation method applied at 50 per cent depletion of soil moisture. Superiority of performance of cv. Cudappah variety was observed over cv. Pratibha in terms of leaf area, chlorophyll content TDM and yield. Application of 270:135:180 kg N:P2O5:K2O ha-1 resulted in higher fresh rhizomes, mother rhizomes and cured finger rhizome yield which was on par with application of 225:112.5:135 kg N:P2O5:K2O ha-1. Interaction influence of the irrigation methods, varieties and fertilizer indicated higher growth and yield in treatment applied with irrigation at 50 per cent soil moisture depletion through drip irrigation with cv. Cudappah and application of 270:135:180 kg N:P2O5:K2O ha-1 which was statistically on par with I1V1F2 and I1V2F3.
