A field experiment was carried out during the wet seasons of 2012 and 2013 at Patna, Bihar, to evaluate the performance of 7 promising rice (Oryza sativa L.) genotypes under 2 crop establishment methods, viz. best management practices (BMPs) and system of rice intensification (SRI). Results revealed that BMPs recorded significantly higher grain yield, biological and production efficiency than to SRI. Among the rice genotypes, ‘IR83387 B-B 40-1’ recorded significantly higher grain yield (4.86 t/ha) followed by ‘Abhishek’ (4.52 t/ha) and ‘Shusk Samrat’ (4.40 t/ha). Rice genotype ‘IR83387 B-B 40-1’ found significantly superior in terms of gross and net returns (66.3×103/ha and 34.5×103/ha) to rest of the genotypes. Moreover, BMP gave the highest carbohydrate equivalent and carbon output (3.34 t/ha and 4.71 t CO2/ha) as compared to SRI (3.17 t/ha and 4.22 t CO2/ha).
