Yam (Dioscorea sp.) is an extremely important delicacy in Cameroon, with some estimated 45,215 hectares devoted to it, and corresponding annual production of 275,101 metric tons. Production is constrained by several factors including the limited availability and cost of planting material, as well...

Beans do not appear inherently suited to infertile soils. A diagnostic effort to define and evaluate soil constraints in African bean production is needed. We suggest bean BNF is host- plant limited, and that BNF in short-season bean is due to inadequate C and N dynamics in the bean plant. In inf...

In recent years (1990-1995) the cassava area in Vietnam has remained stable, or has increased slightly in the south due to the new demand for cassava roots used for starch processing. Therefore, our cassava breeding program, in collaboration with CIAT, has put a high priority on developing new va...
