A field experiment was conducted during both kharif & rabi seasons in 2009-10 & 2010-11 at Instructional farm, Krishi Vigyan Kendra, Angul district under mid central table-land zone of Odisha to study the effect of different rice-based cropping system on system productivity, profitability, sustainability and soil health. The treatments consisted of seven cropping sequences and replicated thrice in randomized block design on sandy loam soil with low to medium fertility level and slightly acidic in reaction, Rice-Brinjal cropping sequence was evaluated to be most remunerative and sustainable with maximum rice equivalent yield of 277.35 q ha-1, production efficiency of 118.02 kg ha-1 day-1, land use efficiency of 64.38%, sustainable yield index of 1.00 , employment generation of 525 man days ha-1, profitability of Rs.510.57 ha-1 day-1, relative economic efficiency of 1404.03 % and net return of Rs.186357 ha-1 year-1. Rice-Greengram cropping sequence reported the maximum increase in available N, P2O5 and K2O and organic carbon content followed by Rice-Blackgram. Rice-Brinjal/Tomato/Onion and Rice-Groundnut cropping sequences has reduced soil fertility. The Nitrogen use efficiency was maximum (118.02 kg grain kg-1 of N applied) in Rice-Brinjal sequence. The traditional sequence of Rice - Fallow system has minimum production efficiency of 41.36 kg ha-1 day-1 with profitability of Rs.37.37 ha-1 day-1, land use efficiency of 32.88 % and sustainable yield index of 0.18. Under the prevalent edaphic, climatic, sequential and socio economical situations the Rice-vegetables cropping sequences have relatively more productive and remunerative but Rice-legumes cropping system were potentially important in nutrient cycling advantages
