El fósforo (P) es el nutrimento más limitante para el rendimiento del frijol común (Phaseolus vulgaris L) en los trópicos y subtrópicos. En zonas marginales deficientes en P donde la producción de frijol deberá ser incrementada para satisfacer la demanda de proteina, los agricultores pobres carec...

Case studies from Costa Rica, Guatemala, and Colombia are reviewed on improved technology adoption to find out to what degree has this technology been adapted to the needs of low income farmers, consider the relationship between new var. adoption and the changes in farm management, and examine th...

Se revisan estudios de caso de Costa Rica, Guatemala y Colombia sobre adopcion de tecnologia mejorada para evaluar hasta donde ha sido posible adaptarla a las necesidades de los agricultores de escasos recursos, considerar la relacion entre adopcion de nuevas var. y cambios en el manejo de las fi...

In this paper we apply an integrated biophysical and economic foresight modeling approach to investigate the impacts of climate change on the global agricultural economy, and the role that new crop technology could play in mitigating these impacts. In particular, we examine how the adoption of a ...

Accurate assessment of crop water uptake (WU) and water use efficiency (WUE) is not easy under field conditions. Carbon isotope discrimination (Δ13C) has been used as a surrogate of WUE to examine crop yield responses to drought and its relationship with WU and WUE. A 2-yr study was conducted (i)...
