Background: Rice and rice based cropping systems are of prime importance in global food production but continuous rice mono cropping and excessive dependence on chemical fertilisers degrade the soil quality, which can be partly solved by changing into rice-legume system. 
 
Methods: The field experiment was conducted during kharif and rabi of 2019-2020 and 2020-2021 at Odisha University of Agriculture and Technology, Bhubaneswar to evaluate direct and residual effect of nutrient management and rice establishment methods on productivity, profitability, nutrient uptake and resource use efficiency in rice-groundnut system. 
&nbsp; 
Result: Transplanted rice increased the yield attributes of rice in both the years resulting in 6.0-8.1% higher grain yield than direct seeding. Integrated nutrient management (INM) significantly improved the growth and yield of rice as compared to sole organic and inorganic. Carryover effect of direct seeding increased growth and yield of succeeding groundnut. Residual effect of organic in preceding rice increased pod yield of groundnut. INM to groundnut increased yield parameters of the crop resulting in 19.7-20.2 and 38.9-40.0% higher pod yields than 100% and 75% soil test based fertiliser, respectively in both the years. Direct seeding of rice with INM practice in both the crops performed superior in rice-groundnut cropping system.
