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 ...
Rainfall as a limiting factor for wheat grain yield in permanent raised-beds
The planting system on permanent raised-beds for rainfed wheat (Triticum aestivum L.) production in the central highlands of Mexico is an option that needs to be documented for moderate-yield environments. Long-term plots ...
Integration of environmental, agronomic, and economic aspects of fertilizer management
Nitrogen fertilization is a substantial source of nitrogen-containing trace gases that have both regional and global consequences, In the intensive wheat systems of Mexico, typical fertilization practices lead to extremely ...
Wheat yield and tillage-straw management system year interaction explained by climatic co-variables for an irrigated bed planting system in northwestern Mexico
Wheat is an important food and income source and estimated demand for wheat in the developing world is projected to increase substantially. The objectives of this study were to gain insight into (i) the effect of tillage?straw ...
