Two years field experiment was conducted during consecutive years of rabi 2012-13 to 2013-14 at Department of Agronomy, Dr. BSKKV, Dapoli on lateritic soils of Konkan, to determine suitability of irrigation method, fertilizer approaches and levels of soil ameliorant to sweet corn. Sweet corn grown under drip irrigation noticed significantly higher green cob, fodder and total biomass (1.67, 1.73 and 3.40 t/ha, respectively) with increment of 10.78, 4.05 and 7.35 %, respectively over check basin method of irrigation. Application of soil test based fertilizer requirement of N,P,K and micronutrients (Cu, Zn, B and Mn) had significantly highest green cob yield (2.05 t/ha) and increment was 71.66, 13.27 and 5.97% over control, recommended dose of fertilizer and soil test based fertilizer requirement of NPK, respectively. However, corn ameliorated with 50% lime requirement recorded the highest green cob and fodder yield (1.67 and 1.74 t/ha, respectively) with increment in the magnitude of 10.40% and 6.03%, respectively over lime control and 25% lime requirement. Economics of treatments revealed that, drip irrigated sweet corn has more net monetary returns (`151.17x103/ha) with benefit: cost ratio of 2.16:1. Sweet corn grown with application of soil test based fertilizer requirement of N,P,K and micronutrients (Cu, Zn, B and Mn) noticed profitable yield potential with high net returns of ` 257.14 x103/ha and 2.31:1 benefit: cost ratio. However, corn ameliorated with 50% lime requirement recorded highest net returns ` 210.84x103/ha, but profitability was highest with application of 25% lime requirement with B:C ratio of 2.20:1.
