Resumen
En Grecia, Costa Rica se evaluó el efecto del sombreamiento sobre el frijol de tres cultivares de maíz de diferente porte. Como testigos se utilizaron parcelas en las cuales se eliminaron las plantas de maíz, un día antes de la siembra de frijol. Se midió además el efecto del fertilizante residual con que se abono esta gramínea, sobre el frijol en relevo. Para lo cual se utilizó como testigo frijol en monocultivo sin fertilizar y con la misma distancia entre hileras de maíz. La producción de esta leguminosa en las parcelas que tuvieron maíz hasta un día antes de su siembra fue estadísticamente igual a la sembrada en relevo con maíz, debido a que los valores de las intensidades lumínicas que indujeron los maíces fueron superiores al valor mínimo que necesita el frijol. La fertilización aplicada al maíz no influyó en la producción de frijol. La diferencia en rendimiento entre los cultivares de frijol , se atribuyó a diferencias entre genotipos.
The shading effect of three corn cultivars of different heights on sixteen cultivars of bush beans was studied in Grecia, Costa Rica. The control was s plot where the corn plant was removed a day before the bean swing. Also the effect of the residual fertilizer from the corn was studied on beans sown on a realy planting system. The control plot used was with beans sown alone, not frtilized and with the same planting distance between rows as of corn. The differences of the penetration of light (luminous intensity on the bean top at pre-bloom and bloom) through the corn plant had no influence on the bean yield. There was no statistical differenceon bean yield beteen the plot which had the cor plantas up to the day before its sowing and the plot with a relay plating system. Differences on yield between bean cultivars were due to genotypic differences. The fertilization or corn had no influence on bean yield.
