Cowpea [Vigna unguiculata (L.) Walp] is an annual legume, considered important as a cash and nutritional security grain legume in the semi-arid regions of sub-Saharan Africa. Cowpea yields in the sub-Sahara African region are low partly due to several biotic stress factors, which includes several...

Cowpea is an important cultivated grain legume pulse, vegetable and fodder crop of African origin. However, yields have been characteristically low as a result of both abiotic and biotic stresses. Among the abiotic stresses, yield losses due to phosphorus (P) deficiency is an important factor....

Anthracnose caused by Colletotrichum lindemuthianum is a major disease of common bean (Phaseolus vulgaris) worldwide. Yellow beans are a major market class of common bean especially in eastern and southern Africa. The objectives of this study were i) evaluate the yellow bean collection for...

Colletotrichum lindemuthianum, the causative pathogen of common bean (Phaseolus vulgaris) anthracnose, is highly variable. Therefore, understanding its race structure and identification of new sources of resistance is necessary for the development of varieties with durable resistance. The...

Aluminum (Al) toxicity causes high yield losses and is directly linked to acidic soils. Application of lime can ameliorate this problem, but it is costly and not feasible for small scale farmers as they need to purchase both seed and lime. Developing maize varieties that are tolerant to Al...

Groundnut (Arachis hypogaea L.) is an important global oilseed crop and a major source of protein and vitamins in many rural areas of Africa. In Zambia, the production of groundnut is limited by several factors, among which Early Leaf Spot (ELS) caused by Cercospora arachidicola Hori, is a major...

Maize ear rots caused by Stenocarpella maydis are among the most important impediments to increased maize production in Zambia. They cause reduction in yield and quality of the maize. The mycotoxins produced by the pathogen have health implications on livestock and humans. Breeding for resistance...

Bean anthracnose caused by Colletotrichum lindemuthianum causes severe common bean (Phaseolus vulgaris L.) yield losses. Breeding for resistance is the best method to mitigate this problem. The objectives of this study were to; (1) screen and identify two common isolates of C. lindemuthianum from...

Soybean is one of the most important cultivated crops in the world with about 6% of the world’s arable land dedicated to its production. Compared to other major food crops, soybean experienced the highest percentage of yearly increases in production area over the period 1968 to 2013 from 29...
