1) PRADAN staff in Eastern India reported on their experience with System of Rice Intensification (SRI) methods between 2002-2007, working with over 6,200 small-holder farmers. 2) SRI methods including young seedling transplantation, wide spacing, and intermittent irrigation led to average yields of 6-8 tons/hectare, double local conventional yields. 3) Adoption of SRI has been increasing as farmers experience higher yields with lower input costs compared to conventional practices. Over 50% of farmers now choose SRI, especially for medium upland areas.
