Yield and Cost Effects of Plot-Level Wheat Seed Rates and Seed Recycling Practices in the East Gojam Zone, Amhara Region, Ethiopia: Application of the Dose–Response Model
Previous studies investigated the effects of seed rates and seed recycling practices on the yield and yield-related variables. However, higher yield does not always guarantee cost-efficiency. This study aimed to investigate ...
Wheat production and breeding in Sub-Saharan Africa: Challenges and opportunities in the face of climate change
Purpose – This paper aims to review the current status of wheat production, farming systems, production constraints and wheat demand-supply chain analysis; the role of international and national breeding programs and their ...
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 ...
Legume-based rotations have clear economic advantages over cereal monocropping in dry areas
Current land use trends show an increasing preference for monocropping – mostly a consequence of policies and incentives aimed at enhancing the intensification of cereals. This shift has caused some to question whether ...
The potential of small-scale rainfed agriculture to strengthen food security in Arab countries
In most Arab countries, domestic agricultural production is insufficient. The gap between production and demand is likely to increase due to climate change and other factors. This review paper examines the challenges and ...
Institutional and farm-level challenges limiting the diffusion of new varieties from public and CGIAR centers: The case of wheat in Morocco
Low adoption of agricultural technologies slows efforts to increase agricultural productivity and enhance rural livelihoods in developing countries. A large body of literature has sought explanations for the problem, but ...
Wheat and barley seed system in Syria: How diverse are wheat and barley varieties and landraces from farmer’s fields?
The present study described the diversity of wheat and barley varieties and
landraces available in farmer’s fields in Syria using different indicators. Analysis
of spatial and temporal diversity and coefficient of parentage ...
Farmers' perceptions on improved bread wheat varieties and formal seed supply in Ethiopia
The paper presents smallholder farmers' perceptions on attributes of bread wheat varieties based on primary data collected from 524 households in four major wheat growing areas of Ethiopia. The results indicated high value ...
Delivering rust resistant wheat to farmers: a step towards increased food security
An important step towards reducing the vulnerability of wheat in Africa and Asia to the Ug99 race of the stem rust pathogen is the substitution of current susceptible varieties with superior resistant varieties. In the ...
Economic Impacts of Legume Varieties and Rotations: The Case of Faba-beans in the Wheat – Based Production Systems of Morocco
While the impacts of cereal-legume rotations on soil health are well documented, the literature on their economic benefits is scanty. By applying the propensity score matching and endogenous switching regression methods ...
