Evaluación campesina del frijol de abono empleado como abono verde en Veracruz, México: Experimentación y beneficios esperados
Soule, M.J. 
En este estudio se investigan los factores vinculados con la decision de los agricultores de experimentar con el frijol de abono (Mucuna spp.), un abono verde, como cultivo intercalado con el maiz en tres aldeas de Veracruz, Mexico. Para evaluar si el frijol de abono podria ser adoptado en gran escala en la region, se examinan tambien las distintas percepciones de los agricultores acerca de lo ...

CIMMYT (International Maize and Wheat Improvement Centre) and other research groups within the Consultative Group for International Agricultural Research (CGIAR) have made major contributions to agricultural development, e.g. underpinning the ‘green revolution’, but it is unlikely they will continue making such far-reaching contributions without the ability to collect, analyse and assimilate l ...

Bijay-Singh et al. 
Blanket fertilizer nitrogen (N) recommendations for large irrigated wheat tracts lead to low N-use efficiency due to field-to-field variability in soil N supply and seasonal variability in yield. To achieve high N use efficiency, a site-specific N management strategy using GreenSeeker? optical sensor was evaluated. We conducted seven field experiments during 2004?2006 at three locations to def ...

Root-root interactions: extending our perspective to be more inclusive of the range of theories in ecology and agriculture using in-vivo analyses
Faget, M. et al. 
Background There is a large body of literature on competitive interactions among plants, but many studies have only focused on above-ground interactions and little is known about root?root dynamics between interacting plants. The perspective on possible mechanisms that explain the outcome of root?root interactions has recently been extended to include non-resource-driven mechanisms (as well as ...
