Re-Evaluating the Malawi Farm Input Subsidy Program by J. Messina, B. Peter, and S. Snapp has just been released in the journal Nature Plants. The paper presents research using net photosynthesis (PsnNet) to evaluate production history and production potential under fertilizer input scenarios in Malawi. The authors were unable to replicate post Farm Input Subsidy Program (FISP) production gains and showed that the spatial delivery of FISP may have contributed to popular perception of widespread maize improvement. Triangulated lines of evidence suggest that FISP may not have been the success it was thought to be. Lastly, the authors assert that fertilizer subsidies may not be sufficient or sustainable strategies for production gains in Malawi.

The Malawi Department of Agriculture and Research Services, Ministry of Agriculture, Technology Release Committee approved the Doubled up Legume Technology for use by smallholder farmers. The DUL technology of pigeonpea with a groundnut understory was evaluated on-farm through a comprehensive country-wide testing program. Several planting arrangements and plant population densities were shown to perform well across a wide range of agroecologies, leading to the release of the technology.
