Cultivars of common bean (Phaseolus vulgaris L.) capable of yielding well at low levels of native or added phosphorus (P) are highly desirable in many tropical production systems. The objective of the present study was to identify geographical regions which might be sources of such genotypes. A t...

Acid phosphatase is believed to be important for phosphorus scavenging and remobilization in plants, but its role in plant adaptation to low phosphorus availability has not been critically evaluated. To address this issue, we compared acid phosphatase activity (APA) in leaves of common bean (Phas...

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...
