Needs assessment of sweet potato production in northern Ghana: implications for research and extension efforts.
The study was carried out to generate baseline information on production, marketing and utilization of sweet potato in Northern Ghana. -
Diagnosing institutional logics in partnerships and how they evolve through institutional bricolage: Insights from soybean and cassava value chains in Ghana
Trade globalisation and climate change pose new challenges for food security in Africa. To unlock smallholder productivity, more understanding is needed of the institutional context and the role of development interventions, such as partnerships, in the food sector. This article proposes institutional logics as a theory and methodology for institutional diagnosis to gain insight into context-embedded negotiation and change processes created by project-based partnership interventions. -
Perceived livelihood impacts and adaptation of vegetable farmers to climate variability and change in selected sites from Ghana, Uganda and Nigeria
In the wake of deepened situations of changing climate, a clear understanding of the perceived impacts and adaptation of climate variability and change on livelihoods of vegetable farmers in Western and Eastern Africa, which is not readily available, is critical for sustainable vegetable production in Africa -
Estimating the Economic Returns to Schooling: Restricted Maximum Likelihood Approach
The economic returns to schooling is a fundamental parameter of interest in many different areas of economics and public policy. The most common technique for estimating this parameter is based on the assumption that the ‘true’ coefficient of education in the earnings equation is constant across individuals. However, this may not often be wholly true and returns to schooling estimates may be biased and inconsistent. -
Reactions of some confectionery groundnut accessions to plant parasitic nematodes infection
Investigations were conducted at four locations in Ghana during 2011 growing season to evaluate some confectionery groundnut accessions reactions to plant parasitic nematodes infection. -

Performance of integrated crop-small ruminant production systems in West Africa
This paper examines the performance of integrated crop-small-ruminant systems in the Subhumid and the Soudan-Sahelian zones of West Africa. Using cross-sectional data from 712 farmers from The Gambia, Ghana, Mali and Benin, the translog stochastic production frontier is used to estimate the technical efficiencies of farmers in each country. -

Performance evaluation of prototype mechanical cassava harvester in three agro-ecological zones in Ghana
Large-scale cassava harvesting, especially during the dry season, is a major constraint to its industrial demand and commercial production. Manual harvesting is slow and associated with drudgery and high root damage in the dry season. Research on mechanisation of cassava production is very low especially in the area of harvesting, and currently there exists no known functional mechanical cassava harvesters in Ghana. -
