The field experiment was conducted during summer 2015 and 2016 under irrigated condition to study the effect of land configurations and deficit irrigation on maize at the Main Agriculture Research Station, University of Agricultural Sciences, Dharwad, Karnataka. The treatments include land configurations (Broad bed and furrow; BBF, corrugated furrow and ridges and furrow methods) and irrigation levels (Irrigation once in ten days, irrigation at 40, 50 and 60 per cent depletion). Results revealed that, ridges and furrow (70.6 q ha-1) and corrugated furrow method (68.9 q ha-1) produced significantly higher and on par grain yield as compared to BBF method of planting (60.9 q ha-1). Whereas, irrigation at 50 per cent (69.7 q ha-1) and 40 per cent (69.6 q ha-1) depletion recorded significantly higher and at par grain yield over other irrigation levels. The combined effect of corrugated furrow method with irrigation at 50 depletion (grain yield of 74.9 q ha-1) and ridges and furrow method with irrigation at 40 (grain yield of 72.8 q ha-1) as well as irrigation at 50 per cent depletion significantly enhanced the growth and yield attributes as compared to the rest of the treatment combinations. BBF method with irrigation at 60 per cent depletion recorded significantly lowest growth and yield parameters of maize.
