Animal husbandry in India plays a pivotal role in the development of rural people and it has transformed from being an integral part of agriculture to a much broader role in the overall national economy. Deficit in the quality green fodder availability has increased over years. Hence, a participatory action-oriented approach was designed to promote intensive cultivation of S. grandiflora for sustainable sheep farming. Two villages in Malavalli taluk were selected. The sheep farmers were sensitized about intensive cultivation of Sesbania through meetings and group discussions. Six farmers were mobilized to take up intensive cultivation of Sesbania. Sesbania saplings were supplied and cultivation practices were monitored. On-farm demonstrations were conducted to demonstrate the effect of supplementation of Sesbania forage on body weight of sheep. Constraints in adopting intensive cultivation of Sesbania were also identified through personal interview. Intensively Sesbania was cultivated and supplemented at the rate of 1 kg/day/lamb over a period of 90 days. The average daily gain in lambs fed with Sesbania was increased significantly (P<0.001) by 12.22 grams/day over the lambs without Sesbania supplementation. Lack of assured irrigation and electricity and non-availability of quality planting materials were the major constraint expressed by the farmers. The results of the present study indicated that intensive cultivation of Sesbania can be successfully adopted at the farm level and green fodder scarcity can be minimized to some extent. The farmers can be made to realize the economic gains in terms of increased body weight gain upon supplementation of Sesbania .
