Intensively cropped highlands areas in the tropics and sub-tropics are susceptible to erosion and declining soil fertility resulting in unsustainable agriculture. Conservation Agriculture has been proposed as an alternative ...

This study analyzes the potential of conservation tillage (CT) for improving maize productivity under a range of soil and rainfall conditions in a semiarid zone of West-Central Mexico, evaluating the consequences of tillage ...

This publication describes progress in collaborative efforts to document, characterize, regenerate, and conserve (both in seed banks and on-farm in situ) maize seed collections from the Americas since 1998. Participants ...

The main farming systems of the Texizapan watershed in southern Veracruz, Mexico (200-1,640 meters above sea level) were characterized through a formal survey in 1995. Farm-level data included an inventory of resources ...

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 ...

Experimental results and farmers surveys in a Mexican community indicates that farmers' seed selection practices protect the phenological integrity of their maize varieties as they define them, despite numerous factors ...

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 ...

This paper focuses on intensifying maize-based cropping systems in the Sierra de Santa Marta Region of Veracruz, Mexico. Following a description of the study area, the paper examines the historical forces that have shaped ...

With support from the Conrad N. Hilton and Ford Foundations and in collaboration with three Mexican non-governmental organizations, the CIMMYT Natural Resources Group (NRG) worked with small-scale farmers in the impoverished, ...
