| Summary, etc |
La presente investigación se realizó en el altiplano occidental de Guatemala, donde el minifundio obliga a los agricultores a aprovechar al máximo sus reducidas parcelas, recurriendo a la siembra en asociación de cultivos. Tradicionalmente, la investigación promovió el monocultivo, pero este tuvo poca aceptación entre los pequeños productores. En la actualidad, los estudios han reconocido que la asociación de cultivos resulta más adecuada para la agricultura de subsistencia. En el valle de Quetzaltenango se inició un programa experimental orientado a desarrollar el sistema denominado cultivos en relevo, que busca mejorar la distribución de maíz y otros cultivos asociados para reducir la competencia entre ellos, garantizar la alimentación familiar y generar excedentes para el mercado. El trabajo presentó los resultados obtenidos en la primera fase experimental de este proceso investigativo |
