Identifying the appropriate germplasm to be improved is a key component of any participatory breeding effort because of its implications for impacts on social welfare and genetic diversity. This paper describes a method ...

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 ...

Results from a study of maize varieties and seed sources in a traditional community in Mexico raise questions about the relevance of models for in situ conservation of crop genetic resources that are based on geographical ...

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. ...

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 ...

Data from a 1994 survey of 82 farmers who grow maize on steep hillsides in Motozintla, Chiapas, provided information on agricultural practices, including the adoption of conservation tillage practices; the profitability ...

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 study explores factors associated with farmers' decision to experiment with velvetbean (Mucuna spp.), a green manure, as a maize intercrop in three villages of Veracruz, Mexico. To asses whether velvetbean might be ...

This paper summarizes factors affecting the agricultural and environmental potential of conservation tillage in maize-based farming systems in Mexico. The author begins by describing some of the implications of soil ...
