A field experiment was conducted during 2005–06 and 2006–07 to find out the most remunerative rice based cropping sequence and source of organic nutrition for sustainable production on sandy clay loam soil, low in available N and S and medium in P and K. RGEY was recorded highest with the treatment comprising application of nitrogen through organic manure along with bio-inoculants (Azotobacter and PSB) followed by only N through organic manure. RGEY and gross return was recorded significantly higher in Rice-Potato-Onion cropping sequence. Net return was also recorded significantly higher under Rice-Potato-Onion cropping sequence except Rice-Rajmash-Onion. Production efficiency was also recorded significantly higherin Rice-Potato-Onion cropping sequence than rest of the treatments. Nutrient uptake had obtained significantly highest value in Rice-Maize-Cowpea cropping sequence. Nutrient status of the soil and microbial profile gets improved significantly under treatment in which 100% RDN was applied through organic manures along with biofertilizers.
