Smallholder market access: the case of groundnut sector in Malawi
This thesis focussed on assessing smallholder groundnut farmers and traders’ access to markets through quality improvement and also, determine the socio-economic factors that influence groundnut farmers when deciding to adopt quality management techniques and the extent/or level of involvement. The …

Farm-Household Analysis of Policies Affecting Groundnut Production in Senegal
Since Senegal's independence in 1960, groundnuts (peanuts) have been the dominant agricultural export crop. Currently, groundnut output levels are on the decline and no clear reason for the downward trend has been found. Privatization efforts are underway as the government explores ways to breathe …

Rhizobia inoculant effects on bambara groundnut growth and yield in Namibia
Bambara groundnut (Vigna subterranea (L.) Verdc) is the third most significant food legume in Africa after groundnut (Arachis hypogea) and cowpea (Vigna unguiculata). It is normally grown in poor soils, is drought tolerant, and has a high potential for nitrogen fixation. Despite that, Bambara …

The Groundnut Market in Senegal: Examination of Price and Policy Changes
… of Senegal is attempting to liberalize the groundnut market. In the past, this market was highly regulated with government-set producer prices, groundnut oil processing mills owned by parastatals, and requirements that all groundnuts be sold to these quasi-governmental organizations. In …

Impact of soil acidity on groundnut productivity in Mpumalanga and KwaZulu - Natal Province
Groundnut [Arachis hypogaea L.] is grown on sandy or sandy loam soil by the smallholders in the lowveld region of Mpumalanga and the Northern coast of KwaZulu-Natal. These soils are highly susceptible to leaching, which leads to acid-soil infertility. The goal of the current study was to examine …

Small scale farmers utilization and perceptions of Bambara groundnut production in South Africa: a case study in a semi-arid region of Limpopo
… challenge, including the use of legumes. Bambara groundnut (Vigna subterranea) is an African indigenous legume that shows great potential to improve the food and economic security of small scale farmers living in semi-arid regions of South Africa. This study sought to investigate the potential for …

Modeling pre-harvest aflatoxin incidence in groundnut (arachis hypogaea l.) using selected soil properties and ambient temperature
Aflatoxin contamination of groundnut (Arachis hypogaea L.) and its products is a worldwide food safety concern. Contamination of kernels during crop growth is associated with adverse soil factors and weather conditions. Therefore, good agricultural practices are an important strategy to minimize …
