This study used both secondary and primary data. Multi-stage random sampling was taken for this study. The districts selected for study were Kalahandi, Balangir and Rayagada of Odisha state. A total number of 120 cotton farmers i.e 71 farmers from small and 49 farmers from large size groups were selected at random based on probability proportion. Analytical tools like Tabular analysis, Cobb-Douglas production function and Garrett’s ranking were used for the analysis. Cobb-Douglas production function was used taking Y i.e. yield of cotton as dependent variable and X1, X2, X3, X4, X5, X6 i. e. for total human labour, farm power cost, manure cost, fertilizer cost,...

Carp farming is one of the most widely adopted technologies in aquaculture sector. The study was carried out in randomly selected South 24 Parganas district of West Bengal. The study aims at assessing economic viability of composite carp culture through analyzing the cost and returns of the technology. Data were collected from 142 fish farmers through personal interview. The average pond area of the farmers was found to be 1.9 acre and mean fish yield was 3.6 t/ha/yr. Rate of return on total investment (ROI) and Benefit-Cost ratio (B: C ratio) for adopters and non-adopters were worked out as 85.84%; 1.86 and 63.03%; 1.63 respectively. Supplementary feed constituted the maximum share in cost of production of fish followed by lease value of pond and pond preparation cost. The study implies composite carp culture technology as economically feasible with impressive benefit-cost ratio.

Skill training and demonstration ofmodules on improved technologies on Crop, Horticulture, Livestock and Fishery wereconducted. Following the DFID framework (1999) the impact on livelihoods of farmerswas measured through finding a comparative position of physical, social, financial, humanand natural assets of the farmers before and after the adoption of the interventions. Astructured interview schedule was developed and data was collected from 87 randomlyselected beneficiaries by personal interview method twice (before i.e., in 2016-17 and afterthe intervention i.e., in 2019-20). The mean value of overall standard of living of adoptedfarmers derived through the addition of the index values of five assets was worked out tobe 2.84 in the post-adoption period against 2.41 in the pre-adoption period. Paired samplet-test indicates the positive and si...

The sample was drawn from South 24 Parganas district in the state of West Bengal in India. The respondents on average obtained 3.67 t/ha annually, but the range was 1.89–5.50 t/ha. The average annual yield at research stations was 8 t/ha, whereas that from the demonstration ponds maintained by the Fish Farmers Development Agency was 3.0 t/ha. The difference of 5 t/h, or 62.5%, constituted yield gap 1. The difference between the average yields obtained by farmers and those from the demonstration ponds was referred to as yield gap 2, which amounted to − 0.67 t/ha, the value being negative because the average yield obtained by the farmers was 22% higher than that recorded from the demonstration plots. These differences were due to the amounts of inputs, the extent to which the farmers adopted the recommended practices, and other socio-economic factors. The study thus showed that the gap is due to the shortcomings of the technology itself and not due to any deficiency in adopting that technology and therefore can be bridged only by developing superior technology of fish production.
