The A field experiment was conducted for 2 consecutive years during 2013–14and 2014–15, at KVK, Kamrup, Assam, India to assessed 6 rice-based cropping systems under irrigated medium land acid soil situation of Kamrup district of Assam. From the mean of 2 years data, it was observed that the highest land use efficiency of 78.63 % was observed in rice - tomato cropping sequences followed by rice-lentil sequence with 78.08 %.The rice-tomato cropping sequences provided the most employment generation (350 man days ha-1) followed by rice - cabbage sequence (290 man days ha-1). The highest rice equivalent yield (290.04 q ha-1) was recorded in tomato grown during rabi after sali paddy followed by cabbage with 176.54 q ha-1. Winter rice–tomato sequence showed 537.09%and 254.72% increase in REY, respectively, over the predominant cropping systems of Assam (winter rice–fallow with REY54.02 q ha-1) and second (winter rice– rapeseed with REY 75.70 q ha-1). The system productivity efficiency was significant with the highest value in winter rice–tomato (119.94 kg ha-1 day-1), followed by winter rice–cabbage sequences (89.31 kg ha-1 day-1). The economic efficiency was significant with the highest value in winter rice–tomato (998.20 ha-1 day-1), followed by winter rice–cabbage sequences (668.37 ha-1 day-1). Nutrient-use productivity of the systems varied from 38.44 to 96.96 kg ha-1 kg-1 of nutrient applied and significantly highest nutrient use productivity was recorded in winter rice–tomato sequence. The highest gross return (395.86 x103 ha-1) and net return (286.48 x103 ha-1) were recorded in case of winter rice–tomato sequence. The highest benefit:cost ratio (3.84) was recorded in winter rice-pumpkin sequence. The highest relative economic efficiency (847.04%) over predominant cropping system winter rice-fallow was recorded in winter rice-tomato followed by 515.31% in winter rice-pumpkin cropping sequence.
