Influence of putative forest refugia and biogeographic barriers on the level and distribution of genetic variation in an African savannah tree, Khaya senegalensis (Desr.) A. Juss
Phylogeographic studies of tropical and subtropical
tree species provide an ideal method to study the role of forest
refugia in the structuring of genetic diversity in contemporary
populations. To date, most studies have ...

Correlations, Path Coefficient Analysis and Heritability for Quantitative Traits in Finger Millet Landraces
Knowledge of association between traits and heritability is important in breeding for purposes of effective trait selection. Such information on finger millet in east Africa is very limited. This study was intended to ...
Adaptability of vetch (Vicia spp.) for potential feed production in Gumara-Maksegnit watershed, North Gondar, Ethiopia
An experiment was conducted to evaluate the adaptability and productivity of different vetch species under the ecological conditions of Gumara Maksegnit watershed in the year 2012. Five vetch species (Vicia dasycarpa, ...
ICARDA Efforts to Promote In Situ/On-farm Conservation of Dryland Agrobiodiversity
Dryland biodiversity has only recently got due attention because of its potential to contribute in overcoming the effects of global challenges caused by land degradation and and climate change (FAO, 1989). More particularly, ...
Parklands for buffering climate risk and sustaining agricultural production in the Sahel of West Africa
In the Sahelian zone of West Africa, crops grown under a
discontinuous cover of scattered trees dominate many
landscapes and constitute the so-called parklands. These
systems reflect the ecological knowledge of the farmers ...
Maize–mucuna rotation: An alternative technology to improve water productivity in smallholder farming systems
Rain-fed crop production systems in the semi-arid tropics of Zimbabwe are characterized by low water productivity (WP), which is partly attributed to inherent low soil fertility, and further exacerbated by continuous ...
Gender and sustainable increase in production through irrigation: The Case of Ntcheu District, Malawi
The need to sustainably intensify agricultural production using irrigation dates as far back as the Egyptian civilization. In modern day Africa, irrigation offers an opportunity to get more crops per drop as a solution to ...
Maize productivity and profitability in Conservation Agriculture systems across agro-ecological regions in Zimbabwe: A review of knowledge and practice
Conservation agriculture (CA) is increasingly promoted in southern Africa as a strategy to improve food
security and reverse soil degradation in the face of climate change. However, the performance of CA
under different ...
Commercial behaviours of smallholder farmers in wheat seed use and its implication for demand assessment in Ethiopia
The article presents the commercial behaviour and its determinants of smallholder farmers in wheat seed use, and its implication for seed demand assessment, based on primary data from 524 wheat farmers in the major wheat ...
