Gene flow among maize landraces, improved maize varieties, and teosinte: Implications for transgenic maize
Proceedings of a forum organized by the Mexican National Institute of Forestry, Agriculture and Livestock Research (INIFAP), the Mexican National Agricultural Biosafety Committee (CNBA), and the International Maize and ...
Three new teosintes (Zea spp., Poaceae) from Mexico
Premise of the study : Teosinte species are the closest relatives of maize and represent an important but increasingly rare genetic resource for maize improvement and the study of evolution by domestication. Three ...
Greenhouse gas emissions under conservation agriculture compared to traditional cultivation of maize in the central highlands of Mexico
In 1991, the International Maize and Wheat Improvement Center (CIMMYT) started a field experiment in the rain fed Mexican highlands to investigate conservation agriculture (CA) as a sustainable alternative for conventional ...
Reduced nitrogen and improved farm income for irrigated spring wheat in the Yaqui Valley, Mexico, using sensor based nitrogen management
Wheat nitrogen-use efficiency in the Yaqui Valley has been estimated at about 0.31. The nitrogen that is not recovered by the crop has important environmental costs that have regional and global consequences. In addition, ...
Policy reforms and mexican agriculture: views from the Yaqui Valley
The overall effects of policy reforms enacted during the 1990s in Mexico on financial and economic profitability ofYaqui Valley agriculture are assessed in this study, which describes the reforms, examines how exogenous ...
Soil quality as affected by tillage-residue management in a wheat-maize irrigated bed planting system
There is a clear need to develop conservation agriculture technologies appropriate for surface irrigated conditions, and the adoption by small-scale farmers. The objective of this paper is to evaluate the effect on soil ...
Soil water content, maize yield and its stability as affected by tillage and crop residue management in rainfed semi-arid highlands
Rainfed crop management systems need to be optimized to provide more resilient options to cope with projected climatic scenarios forecasting a decrease in mean precipitation and more frequent extreme drought periods in ...
