In: Agronomy JournalSummary: Se ha observado que las pequenas diferencias en el tipo y epoca de contruccion de los camellones y el cultivo temprano subsiguiente del frijol (Phaseolus vulgaris L.) tienen una influencia bastante considerable sobre el rendimiento. Con el objeto de determinar el efecto sobre el rendimiento del frijol pinto se llevaron a cabo 3 tratamientos con camellones y practicas de cultivo, aplicados cerca de la epoca de siembra. Los tratamientos con camellones fueron: pre- emergencia (justo antes de que las plantas emergieran), en la epoca de siembra, post-emergencia (inmediatamente despues de la emergencia de las plantas) y testigo. El tratamiento de pre- emergencia se cultivo una vez, despues de la fomracion de camellones y antes del primer riego. Los tratamientos de la epoca de siembra y post-emergencia se cultivaron 2 veces despues de la formacion de camellones y antes del primer riego, y el tratamiento testigo no se cultivo despues de la siembra, excepcion hecha de la arada despues del primer riego. Los tratamientos influyeron significativamente en el rendimiento de semilla y materia seca, ocupando los siguientes lugares: pre-emergencia mayor que siembra mayor que post-emergencia mayor que testigo. El efecto del tratamiento se correlaciono con un contenido de agua del suelo superior a los 15 cm. en la estacion temprana y con la pudricion radical, pero no con la temperatura del suelo. Se encontraron resultados consistentes similares para 3 epocas de siembra. Los rendimientos en relacion con las epocas de siembra ocuparon el siguiente orden: epoca mas tardia mayor que intermedia mayor que epoca mas temprana. (RA-CIAT)Summary: It has been observed that small differences in the type and timing of ridging and subsequent early cultivation of bean (Phaseolus vulgaris L.) had seemingly large influences on yields. Three ridging and cultivation treatments, imposed near planting time, were conducted to determine the effect on pinto bean yield. The ridging treatments were preemergence (ridged just before plants emerged), planting ridge (ridged at planting time), postemergence (ridged after plants emerged) and control. The preemergence treatment was cultivated once, after ridging just prior to the 1st irrigation. The planting-ridge and postemergence treatments were cultivated twice after ridging and prior to the 1st irrigation, and the control treatment was not cultivated after planting except for furrowing prior to the 1st irrigation. The yields of both bean seed and total DM were significantly influenced by all treatments, with the following ranking: preemergence more than planting-ridge more than postemergence more than control. The treatment effect was correlated with soil water content above 15 cm in early season and root rot infection but not with soil temperature. Similar consistent results were found for 3 planting dates. The planting date yields were ranked latest more than intermediate more than earliest. (AS)
