A pilot project on the use of Farmer Participatory Research (FPR) methodologies with the objective of enhancing farmer adoption of practices that minimize soil erosion in cassava-based cropping systems, was conducted jointly by DOA and DOAE with technical and financial support from CIAT in two si...
Nutritional studies of cassava have shown that in high-P acid laterite soils, there was no response to P application during four years of consecutive cropping. In low-P soil, even though cassava initially responded to 100 kg P2O5/ha, the response gradually declined. The optimum economic dose of P...
Annual growth of cassava production in the main cassava production areas during the last five years seems to have kept pace with the increase in population, while the harvested area of cassava increased only 0.6% annually.

This paper describes briefly the most common cropping systems and production practices presently used by farmers. It also reviews the resul...
Over the period 1994-1996, seven batches of seeds and two of meristem tissue cultures were evaluated and selected. As important as root yield is the trait starch content (or dry matter content) if a clone is to be accepted as a starch cultivar. At the time of reporting a number of clones have bee...
