Resumen
El objetivo del presente trabajo fue determinar el efecto del raleo sobre los componentes del rendimiento en dos variedades de okra (Abelmoschus esculentus). El 20 de octubre de 2008, siguiendo un diseño completamente aleatorio con arreglo factorial (variedades y raleo) se sembró en cada unidad experimental un total de 40 semillas (dos por golpe de siembra) de la variedad correspondiente. A los 38 días, se raleó, dejando una planta por golpe de siembra, en las parcelas indicadas. Los frutos fueron cosechados inmaduros desde diciembre de 2008 hasta marzo de 2009. Las variables analizadas fueron: peso total de frutos por parcela durante todo el ciclo de producción, peso por parcela por cosecha, peso por fruto, número total de frutos durante todo el ciclo de producción y número de frutos por cosecha. Hubo una tendencia (P = 0,054) a que el peso total y el peso por cosecha sean superiores en las parcelas sin raleo para ambas variedades. El raleo disminuyó significativamente el número de frutos totales y el número de frutos por cosecha en ambas variedades, debido a que las parcelas raleadas presentaban la mitad del número de plantas. Por último, no hubo un efecto significativo del raleo sobre el peso promedio del fruto en ninguna de las variedades estudiadas.
The purpose of this paper was to determine the effect of the thinning on fruit yield components in two okra (Abelmoschus esculentus (L) Moench) varieties. On October 20, 2008, following a completely random design with factorial arrangement (varieties and thin) a total of 40 seeds (two per hill) of every variety were sown in the experimental unit. Thirty-eight days later they were thined, leaving a plant per hill, in each plot. The fruits were harvested immature from December, 2008 until March, 2009. The measured variables were: total weight of fruits per plot during the reproductive period, fruit weight per plot per harvest, weight per fruit, total number of fruits during reproductive period and number of fruits per harvest. There was a trend (P = 0,054) that the total weight and the weight per harvest were highest in the plots without thinning for both varieties. The thinning diminished significantly the number of total fruits and the number of fruits per harvest in both varieties, because the thinned plots were presenting half of the number of plants. Finally, there was no significant effect of the thinning on the average weight of the fruit in any of the studied varieties.
