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...

Bean ( Phaseolus vulgaris check for this species in other resources L.) production in Africa is constrained by edaphic stresses. A pan-African effort, Bean Improvement for Low Fertility in Africa (BILFA), was initiated in 1990 to screen beans for tolerance to several edaphic stresses. In the fir...

Inadequate nitrogen nutrition is a major constraint to the performance of common bean (Phaseolus vulgaris L.) in sub-Saharan Africa. Twenty six lines selected for good performance under N-limiting conditions were further evaluated at two locations in Uganda to determine the mechanisms allowing go...

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...
