Additional index words. modeling, yield efficiency, partitioning, harvest indexAbstract. The modern olive industry is increasingly interested in olive cultivars that start producing early and remain relatively small, because they are suitable for super highdensity orchards. Some cultivars are better suited to this than others but it is not clear why. Understanding the mechanisms that lead to early production and reduced canopy size is therefore important. The object of this study was to investigate whether differences in vigor across olive cultivars are related to earliness and abundance of bearing. We analyzed tree growth and productivity in young coetaneous trees of 12 olive cultivars, grown together in the same orchard. Trunk diameter increased over the observation period, reaching significantly different values across cultivars. Canopy volume also increased, reaching 2-fold differences between the minimum and the maximum values. Cumulative yield increased, reaching up to 3-fold differences. When the cumulative yield at the end of the experiment was plotted against the final trunk diameter, no correlation was found. A significant correlation was found when cumulative yield was plotted against the increment in trunk diameter during the observation period for which yield data were collected. This relationship improved (i.e., R 2 rose from 0.57 to 0.83) when yield efficiency [i.e., cumulative yield per unit of final trunk cross-sectional area (TCSA) or per unit of canopy volume] was used instead of yield. These results clearly showed that trees that produced proportionally more (i.e., higher yield efficiencies) grew less. We conclude that, in young olive trees, vigor is inversely related to early bearing efficiency, which differs significantly across cultivars. The results support the hypothesis that early and abundant bearing is a major factor in explaining differences in vigor across olive cultivars.The olive industry requires canopy reduction to allow super high-density orchards which permit earlier production and continuous mechanical harvesting (Rallo et al., 2007;Tous et al., 1999). This has stimulated much research into reduced vigor or even dwarf cultivars

“…Presently an intensive high density hedgerow growing system is developing for the future olive (Olea europaea L.) industry and is being studied world-wide (Tous et al, 1999;Dag et al, 2006;De la Rosa et al, 2007). This relatively new olive growing system is based on planting distances of 1.2-2.5 × 4 m producing a hedgerow canopy kept at a diameter of 1.5 m and a height of 2.5-3.0 m. These orchards are harvested with an over-head harvester found considerable more efficient than the trunk and scaffold shakers used in the more spaced conventional rain fed or intensive orchards (Tous et al, 1999;Lavee, 2006Lavee, , 2010Pastor et al, 2007;Vossen, 2007).…”

The increase of tree number per hectare enabled harvesting a commercial yield already 3 years after planting (Dag et al, 2006;De la Rosa et al, 2007).…”

The high-density planting system recently adopted for olive, facilitates the use of efficient over-head mechanical harvesters. To accommodate the harvester only cultivars with restrained vegetative vigor can be used and managed to limit tree size while maintaining high productivity. Spray application of the 0.05% "Magic" (a commercial product containing 50 g L -1 uniconazol), or soil application of 2 and 4 g tree -1 "Magic", were tested to control the canopy size of fruitful vigorous cultivars to suit the high density hedgerow system and over-head harvesting. Two year old plants were chosen for the initial application. Soil application of 2 g "Magic" (0.1 g tree -1 uniconazol) caused a satisfactory balanced growth inhibition of the vigorous cvs. Barnea, Leccino and Picholine to suit the high density hedgerow system. Thus, a significant increase of the choice of cultivars to be used for over-head harvesting could be significantly increased. The use of vigorous cultivars treated with uniconazol for over-head harvesting started in commercial plantations in 2006. In some cases an increase of the annual dosage was required with aging of the trees. This required increase of the annual soil application of uniconazol with aging of the trees needs further observations. An increase in fruit production due to the optimal uniconazol treatment was apparent, though results were rather erratic. Still, production in treated orchards was at least within the country's average for each of the tested cultivars during the experimental years.Additional key words: gibberellins biosynthesis inhibitor; hedgerow orchard; over-head harvester. Resumen Adaptación de variedades vigorosas de olivo al cultivo en seto de alta densidad mediante aplicación al suelo de uniconazol, un inhibidor de la síntesis de giberelinasEl sistema de cultivo en seto de alta densidad, recientemente adoptado para el olivo, facilita el uso eficiente de cosechadoras cabalgadoras mecánicas. Para que la cosechadora pueda trabajar es necesario utilizar cultivares con poco vigor vegetativo manejados de manera que se limite el tamaño del árbol manteniendo alta productividad. Para controlar el tamaño de la copa de cultivares vigorosos a fin de adaptarlos al cultivo en seto con alta densidad de plantación y recolección con cosechadora cabalgadora, se probó la aplicación en pulverización de "Magic" al 0,05% (producto comercial que contiene 50 g L -1 de uniconazol), o la aplicación al suelo de 2 y 4 g de "Magic" por árbol, utilizando plantas de dos años para la aplicación inicial. La aplicación al suelo de 2 g de "Magic" (0,1 g uniconazol por árbol) en tres cvs vigorosos, Barnea, Leccino y Picholine, provocó una inhibición de crecimiento satisfactoria y equilibrada. Por tanto, esta técnica puede proporcionar un mayor número de cultivares adaptados a la recolección mecánica con cosechadoras cabalgadoras. El uso de cultivares vigorosos tratados con uniconazol para recolección con cosechadora mecánica se inició en 2006 en plantaciones comerciales. En algunos casos fue n...
