Chimanga cha makolo, hybrids, and composites: an analysis of farmers' adoption of maize technology in Malawi, 1989-91
This paper profiles farmers' adoption behavior and varietal choices with respect to local and improved maize technologies (variety, fertilizer application, and other agronomic practices) in three agroeconomic zones of ...
Wheat supply in Kenya: production technologies, sources of inefficiency, and potential for productivity growth
Kenya is projected to remain a net importer of wheat to the end of this century. To reduce the growing dependence on imports, the government has proposed measures to stimulate domestic production and curb wheat consumption. ...
Impact of Mexican germplasm on Brazilian wheat cropping: an ex-post economic analysis
This paper reviews and analyzes economic returns to wheat research in Brazil's main wheat-producing regions in Rio Grande do SuI and Paranci. Between 1975 and 1991, the area planted to wheat in Brazil increased significantly ...
The economic returns to institutional innovations in national agricultural research: on-farm research in IDIAP Panama
The paper presents a method for analyzing the returns to investment in on-farm research. It then applies the method to a location-specific maize research program in Caisan, Panama. The results show a rapid adoption of the ...
The rate and sequence of adoption of improved cereal technologies: the case of rainfed barley in the Mexican Altiplano
In efforts to understand the process of agricultural develoµtent, economists and other social scientists have invested substantial resources in literally hundreds of studies of the adoption of new agricultural technologies. ...
