Field experiment was conducted at College of Agriculture, V. C. Farm, Mandya during kharif, 2014 on sandy loam soil to find out the performance of maize to gypsum and boron under different nutrient management practices. The experiment was laid out in Split plot design with three main treatments viz. package of practices, UAS, Bengaluru (M1), STCR dose for targeted yield of 90 q ha-1 (M2) and STCR dose for targeted yield of 110 q ha-1 (M3) and six sub-treatments viz., control (S1), 200 kg gypsum ha-1 (S2), 2.5 kg borax ha-1 (S3), 5 kg borax ha-1 (S4), 200 kg gypsum + 2.5 kg borax ha-1 (S5) and 200 kg gypsum + 5 kg borax ha-1 (S6). Among different nutrient management practices, M3 recorded significantly higher grain yield (93.0 q ha-1), stover yield (184.25 q ha-1), growth and yield attributing parameters compared to M1 and was found to be on par with M2. Two per cent deviation (88.78 q ha-1) was observed in M2 when compared M3. Among gypsum and borax treatments, S4 recorded significantly higher grain yield (89.86 q ha-1), stover yield (160.78 q ha-1), growth and yield attributing parameters, over S1 and S2 and was on par with S3, S5 and S6.
