RTDP On-farm grain yield data 1995-1999

RTDP (Reversing Trends in Declining Productivity, 1997-2000) and RTOP (Reaching Toward Optimal Productivity in Intensive Rice Systems, 2001 to 2004) Mega-Projects are part of Irrigated Rice Research Consortium (IRRC, est. 1997) during its Phase I and Phase II implementation, respectively. The Mega-projects were funded by the Swiss Agency for Development and Cooperation (SDC), Internatioal Fertilizer Industry Association (IFA), Potash and Phosphate Institute (PPI & PPIC), and International Potash Institute (IPI). The framework provided for a partnership between the International Rice Research Institute (IRRI), NARES, non-governmental organizations (NGOs), and the private sectors in 10 Asian countries.The RTDP project focused on regional research needs in irrigated rice ecosystems and developed principles for site-specific nutrient management (SSNM), while RTOP focused on technology delivery and impact (continuing onto Phase III, 2005 to 2008).
