The effect of soil fertility on the response of field beans (Phaseolus vulgaris L.) to inoculation with Rhizobium leguminosarum bv. phaseoli was investigated at five sites in northern and central Malawi. A split-plot design consisting of (a) un-inoculated plants, (b) inoculated plants and (c) N-f...

The African Bean Yield and Adaptation Nurseries (AFBYANs) were designed to facilitate the distribution of elite lines among the national programs in SADC and to supply information on agro-ecological zones and the lines adapted to them. Twenty five entries have been grown in each of the AFBYAN`s (...

Bean common mosaic virus (BCMV) is seed transmitted and the most important virus disease of beans in Africa. A breeding programme was initiated in 1990 in Uganda to develop lines with resistance to necrotic strains that predominate in the continent. Evaluation of field layout on infection level s...

Cassava (Manihot esculenta Crantz) is a hot-climate crop that is also grown in cool areas of the highland tropics, where yields are reduced. The purpose of this study was to evaluate the effect of growth temperature on photosynthesis of two cassava cultivars from contrasting habitat and to determ...

Common bean still is the basic food in the Walungu region and the almost only source of proteins. With farmers from Walungu in general and the women of the organisation Femmes solidaires pour le Développement du Bushi (FESODEBU) in particular, the team of the PNL/Mulungu has done a survey to defi...
