The influence of crop establishment techniques and sources of nutrients on productivity, energetics and economics of rice was studied in red clay loam soil. The SRI establishment technique recorded significantly higher grain and straw yield (10171 and 11265 kg ha^-1 respectively), total energy ouput (290329 MJ ha^-1), energy output: input ratio (15.78), gross income (666.58 Rs. ha^-1), net income (49256 Rs. ha^-1) and B:C ratio (2.84) compared to transplanting and aerobic techniques. Among the sources of nutrients, application of FYM + recommended NPK recorded higher grain and straw yield (8871 and 9938 kg ha^-1, respectively), total energy output (254629 MJ ha^-1) and gross income (58196 Rs. Ha^-1), whereas application of recommended NPK recorded significantly higher energy output: input ratio (15.00). In-situ incorporation of green manure (Sunnhemp) + Recommended NPK recorded higher net income (42636 Rs. Ha^-1) and B:C ratio (2.79) as compared to other treatments.
