Common bean (Phaseolus vulgaris L.) is an important legume crop grown for household revenue, food and nutrition security in many parts of the world. Common bean is classified into Andean and Middle American gene pools. Most of the beans grown in east and southern Africa countries including Zambia...

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...

Cowpea (Vigna unguiculata L. Walp) is an important legume crop, but drought and soil infertility, especially Phosphorus (P) deficiency are primary constraints for its production. Three studies, a field, greenhouse and hydroponics experiments were carried out at the University of Zambia to...

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...

Yield is a quantitative trait known to be influenced by changes in the environment in which the crop is grown, suggesting the need to evaluate soybean lines in different growing regions to assess their adaptability and stability. The objective of this study were to: (i) Determine yield stability...

Numerous plants are considered weeds in agriculture and reduce crop yield and quality. Eliminating the deleterious effects of weeds is the goal of weed management. Herbicides are one of the methods of weed management despite some being persistent in the soil. Herbicides such as Stellar star whose...

Aluminum (Al) toxicity in acidic soils is a major constraint to common bean (Phaseolus vulgaris) production. The genetic architecture of Al toxicity resistance in common bean is not well understood. The objective of this study was to identify the quantitative trait loci (QTL) for resistance to...

Zambia’s many seed companies are involved in maize cultivar development with the primary focus of breeding for yield and disease tolerance. Despite having high yielding potential, most available maize cultivars are greatly affected by drought and heat stress. The parental line stock used in the...

Conservation Agriculture has been recommended as a sustainable farming system for many crops in Zambia based on reported improvements in soil infiltration, moisture, soil carbon, microbial activity and reduced bulk density over time. However, the effects in groundnuts such as plant development,...
