Innovations in resource management for sustainable rice based farming

December 2011

Agricultural practice cannot be sustainable unless and until it is improving or at least conserving the natural resource base. There is need for a shift in outlook of viewing only the immediate benefits of farming practices. Rather, farming practices should be judged in terms of its effects on natural resources and environment, besides benefits in terms of yield and quality. Some ways and means of managing external...
