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...

In many agricultural systems around the world, competition from weeds is one of the major factors reducing crop yield and farmers‟ income. To this effect many strategies have been developed to manage weeds. One such strategy is cultural weed control. However, cultural weed control is tedious and...

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...

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...

The study was undertaken to assess the genetic diversity among some selected Zambian rice (Oryza sativa L.) accessions using Simple Sequence Repeat (SSR) molecular markers. There appears to be little or no information on the genetic or agronomic traits of the locally grown rice crop in Zambia....

Striga asiatica is a noxious, obligate hemi-parasite of cereal grasses that causes grain yield losses in susceptible maize genotypes in Southern Africa. The development of host plant resistance is one of the most practical Striga control strategies. A study was carried out to identify genotypes...

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...

Common bean (Phaseolus vulgaris) is an important nutritional component in the diet of more than 300 million people around the world. Its production is limited by drought and aluminium toxicity among other abiotic factors. Correction of acidity-related soil constraints such as aluminium toxicity...

Common bean (Phaseolus vulgaris L.) is highly constrained by water deficit especially occurring during the reproductive development which significantly reduces the grain yield. A late planted crop, is likely to experience water stress. The purpose of the study was to determine the association of...

Beans are an important crop in Tanzania grown by a wide range of farming communities. Its production, however, is very low due to various factors of which drought is becoming very important due to its frequency in the recent past. Provision of bean varieties that would withstand drought is...
