Poor and subsistence farmers, lacking hybrid and improved maize varieties, struggle daily to eke out an existence from low yielding plants that offer little resistance to destructive insects and diseases. In many of the ...

This manual presents methods for designing formal surveys that measure and analyze the adoption of agricultural technology. First it discusses the rationale for undertaking an adoption study and the issues involved in ...

This study presents a methodology (in five steps) for assessing the impact of information and technologies generated by a crop management research (CMR) program. The methodology is demonstrated by estimating the return to ...

This manual presents a set of procedures for doing an economic analysis of on-farm agronomic experiments wich will help in selecting treatments for furter experimentation and for developing farmer recommendations. The ...

This paper proposes a conceptual framework for analyzing the organization and performance of national maize seed industries. The authors begin by reviewing what several leading economic paradigms have to say about the ...

This paper discusses the centers of origin and diversity for bread wheat; sketches historical patterns in the sources and use of wheat genetic resources in modern plant breeding; identifies and compares indicators of genetic ...

The impacts of maize breeding research for non-temperate environments in the developing world by national agricultural research systems (NARSs) and the International Maize and Wheat Improvement Center (CIMMYT) over 1966-90 ...

This paper describes the current state of international plant breeding research and explains why centralized approach to germplasm improvement, so successful in the past, is being transformed by decentralized local breeding ...

Spatial diversity indicators may serve an important function for policymakers as they seek to manage crop genetic diversity and potential externalities associated with diffusion of some types of genetically improved crops. ...

Improvements in the production characteristics of quality protein maize (QPM) are currently leading to its reintroduction in various areas of the world, both for human and animal consumption. Although the improved QPM ...
