The diffusion system of rice variety Rajshree : a case of rapid adoption

The present study was conducted in Samastipur district of Bihar where rice variety Rajshree was rapidly adopted which is a superior variety for lowland with water stagnation up to one meter. This variety was adopted by the rice growing community within five years of its release by central variety release committee. The study gives insight in the process of rapid adoption and finds the factor behind it.The superior technological characteristics of the Rajshree variety and education level of farmers that proved crucial in rapid adoption of Rajshree variety over time tested local variety ‘Bakol’ which could not withstand stress due to drought. The curvilinear regression analysis show that about 73.6 per cent change in adoption quotient can be explained by income, lowland area and perception about technological characteristics of Rajshree variety.
