Calidad de la cosecha de trigo en México: ciclo primavera-verano 2006
(CONASIST; CONATRIGO, 2008)
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 ...
Earthworm activity and soil structural changes under conservation agriculture in central Mexico
Crop residue mulching combined with zero tillage and crop rotation, known as conservation agriculture (CA), is being promoted as an alternative system to revert soil degradation in maize-based farming in the central highlands ...
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 ...
Global warming potential of agricultural systems with contrasting tillage and residue management in the central highlands of Mexico
Conservation agriculture based on (1) minimal soil movement, (2) retention of rational amounts of crop residue, (3) economically viable crop rotations restores soil fertility. Conservation agriculture improves soil ...
Sustainable improvement of agricultural production systems in the mixteca region of Mexico
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, ...
Tillage and residue management effects on soil quality in maize and wheat systems in the highlands of Central Mexico
(CIMMYT / Wageningen University, 2008)
Análisis del sistema mexicano de investigación agropecuaria
En la decada del 90, el sector agropecuario mexicano genero alrededor del 5% del PHI y el 2.5% de las exportaciones. A pesar de su reducida contribucion al PHI, el sector agropecuario tiene una gran importancia economica ...
