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).
