The DAP weeding project extension promoted the outputs of the earlier project (R7401) to farmers in the Teso farming system (TFS) of Uganda (Kaberamaido, Katakwi, Kumi, Pallisa and Soroti Districts). The extension phase was jointly managed by the Serere Agricultural and Animal Research Institute (SAARI) of the National Agricultural Research Organisation (NARO) of Uganda and D Barton(UK)Limited. The Project was part of the portfolios of two DFID research programmes, the Livestock Production Programme (LPP) and the Crop Protection Programme (CPP). Original project activities took place between 1999 and 2002. The project was extended for 14 months (2003-2004) and benefited from a further extension for 10 months (2005).
