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....

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...

Soybean is an important crop with many important properties. The use of soybean varies from stock feed, biodiesel, edible oils and high protein food products, to soil amendment resulting from its nitrogen fixing ability and is a profitable cash crop. Zambia has a number of soybean varieties which...

Groundnuts are one of the important household food security crops grown in Zambia. The crop provides minerals, fats, protein, vitamins and it also acts as a source of income for resource poor farmers. Production and utilization of groundnuts in the small holder setting is hampered among others,...

Beneficial effects of selenium (Se) can be delivered to humans through enriched plant foods. However, breeding plants to be more efficient at Se accumulation can complement enrichment efforts. This study was aimed at determining the inheritance of Se accumulation for the purpose of developing...

Beans (Phaseolus vulgaris) are an important food as a source of protein and fit well in the farming system of smallholders in Zambia. Unfortunately the grain is prone to stor-age losses mainly due to storage insects. Bruchid (Callosobruchus maculatus) attack on dry beans is a serious storage...

Maize (Zea mays L) is an important multi-purpose staple cereal crop in Zambia.More than 70% of people derive their livelihood from agriculture of which maize production is the major enterprise. Maize production is affected by biotic and abiotic stresses. Most varieties developed in the Zambian...

The study was conducted to determine and characterize grain yield, grain yield stability, uniformity of three way cross(TWC), single cross (SC) hybrids and open pollinated (OP) varieties of sorghum and relate their grain yield to morphological and physiological attributes via leaf area index and...

This study was carried out during the 2008/09 season under irrigated conditions. It was conducted at the University of Zambia (UNZA), School of Agricultural Sciences Field Station. The objective of the study was to determine the yield response of selected varieties of a leafy vegetable, Rape...
