A field experiment was conducted in the Instructional Farm, Department of Agronomy, OUAT, Bhubaneswar in 2019-20 and 2020-21. In the kharif season, rice was grown in Randomized Block Design with three different establishment methods namely, Direct sowing, Non Puddled Transplanting and Puddled Transplanting. In the Rabi season greengram was taken in those plots where the residual effect of rice establishment methods was taken as main plots, two irrigation schedules i.e., one irrigation at the pre-flowering stage & No irrigation was taken in sub plots. In sub-sub plots nutrient management schedules were taken i.e., no fertilizer, 2% spray of NPK 19-19-19 at pre-flowering and flowering stage & 100 kg soil application of DAP. DSR-based system was found to be economically profitable even though PTR-based system has produced higher system yield. Crop grown with irrigation performed better over no irrigated plots. Similarly, soil application of fertilizers has shown higher system productivity and profitability over foliar application followed by no fertilizer

From the above study, it can be concluded that even though for system productivity and production efficiency PTR-based system was higher still DSR system performed better concerning system profitability. As moisture during the rabi season is one of the critical factors, hence providing one irrigation at pre flowering stage will serve the purpose. Soil application of fertilizers performed better over foliar application as macronutrient needs are fulfilled better through soil application because of its requirement in higher quantities
