A Comparative cost and return analysis of different cropping systems and integrated farming systems adopted in climate smart agricultural situation in upper Brahmaputra Valley Zone of Assam

Rice is the staple crop in the state of Assam. The study was conducted in locations which are climate resilient in nature. Two Agriculture Development Officer’s circles and from each circle three villages were selected. From each village, 20 farm families were selected randomly. Here, different cropping sequences were studied to analyze economically viable one. It was revealed from the study that out of six different combinations of cropping sequences/patterns both Flood tolerant rice - Cauliflower and Fishery cum Duckery sequence in adopter’s combination were found the most viable one and the pooled benefit-cost ratio for both the combinations was calculated as 2.14. In case of non-adopter’s combination, the most viable cropping sequence was recorded as normal winter rice - cauliflower and its pooled benefit cost ratio was calculated as 2.02 followed by normal winter rice - cabbage sequence. Other cropping sequences were not found profitable. The flood tolerant rice - toria and normal winter rice - toria sequences in both adopter’s combination and non-adopter’s combination were found non-viable.
