Barley is one of Ethiopia's most important cereal crops, ranking fifth in total cereal production, after maize, wheat, teff, and sorghum. Based on its intended use,it is divided into two types: food barley and malt barley. This study investigated the...

This BOOK is the outcome of the collaborative endeavors of diverse partners and stakeholders addressing the challenges of seed systems and scaling faba bean and chickpea innovations in Ethiopia. It is the second of two BOOKs which focuses on faba...

Wheat, cultivated on a total area of 2.1 million hectares annually with a
total production of 6.7 million tons, is one of the most important food
security crops in Ethiopia. However, there is a huge gap between wheat
production and supply due to the...

Agriculture and agri-food systems of the highly vulnerable Middle East and North Africa
(MENA) region needs a radical transformation under a changing climate. Based on a two-year effort,
initially we developed a mega hypothesis on how to achieve...

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 the focus has been mainly on...

In Morocco, the adoption of recent improved wheat varieties is low, casting doubt on whether investments in wheat research are paying off. This paper generates estimates of the returns to the national and international investment in wheat research...

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 the yield effects of plot...

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 legume–cereal rotations can...

Successful scaling of agricultural technology requires a spatial explicit framework for targeting the right variety at the right place. This entails a multi-criteria evaluation (MCE) approach, using a set of determining factors to delineate the...

The paper presents the yield gaps, adoption of improved varieties and the commercial behaviour in seed of smallholder chickpea producers based on the primary data collected from 612 randomly selected farmers covering 36 kebeles from 18 chickpea...

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 approaches in wheat genetic...

This book, Political Economy of the Wheat Sector in Morocco: Seed Systems, Varietal Adoption, and Impacts, documents the studies conducted on the wheat sector in general. It also documents the wheat seed system, its adoption and impacts in Morocco...

The genetic progress in seed yield and yield related characters of 10 kabuli chickpea varieties released by the
Ethiopian Chickpea Crop Improvement Program from 1974 to 2017 was assessed during the main cropping
season. The varieties were evaluated...

This study was conducted to determine the interaction between chickpea genotypes with the environment (GxE) on the yield stability and adaptability of desi type chickpea genotypes (Cicer arietinum L.). Seventeen chickpea genotypes were evaluated for...

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 of attainment indices for...

The chapter presents the adoption and diffusion of rust resistance varieties in terms of area with simultaneous reduction in the number of farmers and area under rust susceptible wheat varieties. Furthermore, factors influencing the adoption of...

ICARDA in collaboration with CIMMYT and/or NARS has developed a number of multi-lateral and bilateral projects to counter the threat of stem rust and yellow rust. This paper summarizes ICARDA’s experiences and lessons learned in implementing these...

In Ethiopia, ICARDA in partnership with CIMMYT and EIAR formulated and implemented two successive projects with focus on stem and yellow rust, which complimented and reinforced each other in order to avert the risks and losses associated with the...

Wheat rusts remain a challenge for wheat production at national, regional and global levels. Empirical evidence shows the emergence of new races and their quick spread across countries and continents with devastating consequences.In response to Ug99...

One of the planned components of the project was technology promotion through demonstration, popularization and on-farm seed production. This chapter documents the approaches, activities, achievements and lessons learned in promoting new rust...

The chapter presents the approaches, achievements and lessons learned in accelerated seed multiplication of early generation seed (breeder, pre-basic and basic) and large-scale certified seed production by NARS and public and private sector including...

This book is the grandstand of the collaborative endeavours of diverse stakeholders in addressing the challenges of wheat production and wheat rusts in Ethiopia within the context of the international efforts across Africa and Asia. It provides a...

The paper highlights the evolution of the organized seed sector and the progressive changes that took place over the last 35 years in Ethiopia. From its ad hoc arrangements and modest beginning in the 1940s, the formal seed sector went through...

Early generation seed production may constitute maintenance breeding of improved variety and regular multiplication and supply of smaller quantities of breeder, pre-basic and basic seed. The main purpose of EGS Early generation seed production is to...

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 growing areas covering 22...

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 out-scaling program for a barley...

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 along with
measurements of...

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 of wheat (Triticum...

Salsola vermiculata is a highly palatable shrub and widely used in rangeland rehabilitation programs, but has short seed
longevity. To identify the most cost effective storage method for S. vermiculata, experiments were carried out to test the...

The study assessed the health quality of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) seed samples collected from formal and informal sector in Ethiopia and Syria. In Ethiopia, several seed-borne fungi were found on wheat samples...

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 possible solutions to...

There is a strong link between formal plant breeding and seed supply. In developed countries, it was the emergence of systematic plant breeding that generated new named varieties and stimulated organized seed multiplication and marketing by...
