Is SRI in Conflict with ‘Conventional Wisdom’? P. Kishan Rao
There have been claims and counter claims about the scientific basis of SRI and its performance on both research farms and farmers’ rice fields. This paper asks some probing questions on the idea, concept and practices of SRI vis-à-vis conventional rice cultivation as understood and experienced by the scientists and farmers at different times.
