The objective of On Farm Testing is to test and evaluate the research findings of Research Stations at the farmer's field and to refine and modify the technologies, if required for better adoption by farmers. It is confirmation of already proven research results under real farming situation. Based on the background information that the farmers do not adopt about 70% of the available technologies and hence it becomes necessary to take up farmer participatory testing of research findings in their own farms. Apart from convincing them it is also given an opportunity to refine or modify the recommendations to suite the requirements of the farmers in a given farming situation. Participatory Rural Appraisal (PRA) was conducted to identify the problems faced by the farmers and based on the priority of the problems OFT was implemented. Economically viable, operationally feasible technologies matching with farmers needs are identified to solve the problem faced by them.
