Agricultural Productivity in the WANA Region
The interest of governments, international organizations, NGOs and the general public has recently been aroused by studies considering the use of existing agricultural technology, the use of innovations in such technology ...
Measuring the effectiveness of extension innovations for out-scaling agricultural technologies
Low adoption levels of agricultural technologies undermine the impacts of national and international agricultural research. Using a combination of an ordered logit and Heckman selection models and a case study from an ...
Assessment of on-farm diversity of wheat varieties and landraces: Evidence from farmer’s fields in Ethiopia
Analysis of spatial diversity, temporal diversity and coefficient of parentage (COP) were carried out along with measurements of agronomic and morphological traits to explain on-farm diversity of modern varieties or landraces ...
Characterization of Goat Population and Breeding Practice of Goat Owners in Gummara-Maksegnit Watershed-North Gondar, Ethiopia
The intentions of this study was characterizing the goat population of Gumara-Maksegnit watershed area by defining the breeding practices of the goat owners in the area, as well as based on physical appearance traits and ...
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 ...
Breeding programmes for smallholder sheep farming systems: II. Optimization of cooperative village breeding schemes
A simulation study was conducted to optimize a cooperative village-based
sheep breeding scheme for Menz sheep of Ethiopia. Genetic gains and
profits were estimated under nine levels of farmers’ participation and
three ...
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, ...
Breeding programs for smallholder sheep farming systems: I. Evaluation of alternative designs of breeding schemes
Village- and central nucleus-based schemes were simulated and evaluated
for their relative bio-economic efficiencies, using Ethiopia’s Menz sheep as
example. The schemes were: village-based 2-tier (Scheme-1) and 1-tier
(Scheme-2) ...
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 ...
Do faba bean (Vicia faba L.) accessions from environments with contrasting seasonal moisture availabilities differ in stomatal characteristics and related traits?
Drought is a major constraint to faba bean (Vicia faba L.) production, and there are many mechanisms by which leaves can regulate water loss. Our primary objective was to test if the origin of the faba bean accessions, ...
