A field experiment was conducted for two consecutive years during 2015–16 and 2016–17 at farmer’s field of Pakorkona village of Kamrup district of Assam to assessed 6 rice-based cropping sequences under rainfed medium land situation for their profitability. The soil of the experimental site was acidic (pH 5.4), sandy loam in texture, medium in organic carbon (0.53%), low in available N (263.40 kg ha-1) and medium in P2O5 (34.60 kg ha-1) and K2O (152.43 kg ha-1). The treatments consist of 6 rice based cropping sequences replicated four times in randomized block design viz. rice (Oryza sativa L.) - rapeseed (Brassica camprestis L.) - fellow; rice - rapeseed - blackgram (Vigna mungo L.); rice– garden pea (Pisum sativum. L.)- blackgram; rice – lentil (Lens culinaris Medic) - blackgram; rice – garden pea- dhaincha (Sesbania aculeta) and rice – lentil- dhaincha. Economic analysis of the cropping sequences revealed the highest gross return (Rs. 1,38,17/- & 1,31,.620/- ha-1) and net return (Rs. 69,540/- & 62,990/- ha-1) were recorded in rice-g, pea-blackgram sequence but the highest benefit:cost ratio (2.19 & 2.12) were recorded in rice-g. pea-dhaincha sequence during 2015-16 & 2016-17 respectively. The economic efficiency was significant with the highest value in rice-g. pea-dhaincha (243.30 & 228.87 Rs. ha-1 day-1), followed by rice-g. pea-blackgram sequences (236.54 & 214.26 Rs. ha-1 day-1) and the highest relative economic efficiency (170.37% & 128.39%) over predominant rice-rapeseed-fallow sequence were recorded in rice-g. pea-blackgram followed by 151.63% & 120.40% in rice-g. pea- dhaincha cropping sequence during 2015-16 & 2016-17 respectively.
