Critics of modern maize and wheat varieties (MVs) have suggested that, in developing countries, yields of these varieties vary more from season to season than yields of farmers’ traditional varieties, thereby exposing ...

This paper examines the economics of introducing conservation tillage into existing maize cropping systems in the state of Jalisco, in the western part of Mexico. A stochastic cost-benefit analysis (SCBA) of introducing ...

Drawing on a series of technology adoption studies carried out by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with national agricultural research systems in Eastern Africa during 1996-98, ...

This paper describes results of a study of the main factors affecting the development of the maize seed industries in Brazil and Mexico (and, by extension, other developing countries). The authors develop a framework that ...

The principal advantage of in situ conservation is that it allows adaptive evolutionary processes to continue in the species that are being conserved. For a cultivated crop species, in situ conservation involves farmers' ...

This paper compares the economics of the abonera maize production system, in which maize is grown in rotation with a green manure crop (velvetbean, mucuna deeringiana), with traditional bush-fallow cultivation of maize in ...

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 report documents the number and types of maize varieties and hybrids released by public breeding programs between 1966 and 1997, describes the varieties and hybrids marketed by public seed agencies and private companies ...

This report of the adoption of maize production technologies in the Southern highlands of Tanzania forms part of a larger study to evaluate the impact of maize research and extension throughout Tanzania over the past 20 ...

This study of the adoption of maize production technologies in Western Tanzania forms part of a larger study to evaluate the impact of maize research and extension throughout Tanzania over the past 20 years. Using a ...
