Beans are grown in Africa in a wide range of environments, mainly in the cool highlands of central and tropical eastern Africa, leading to a diversity of cropping systems and agronomic constraints to production. Beans are cultivated for large-scale production or home consumption either in monocul...

El frijol se cultiva en Africa en un amplio rango de ambientes, principalmente en las areas montanosas templadas de las regiones central y oriental tropical de Africa, lo cual supone diversos sistemas de cultivo y limitaciones agronomicas a la produccion.

The effectiveness of supplementing local bean (Phaseolus vulgaris) mixtures with varieties resistant to angular leaf spot, caused by Phaeoisariopsis griseola, was evaluated in the Great Lakes region of Africa. The severity of angular leaf spot was lower (P = 0.05) in farmer mixtures supplemented ...
