“…The accumulated yield of 51 Mg ha -1 of olives, at the highest density, was higher than the approximately 36 Mg ha -1 of olives, for the same period and cultivar, grown at similar spacing in Catalonia (Tous et al, 2007). This may reflect more favourable growing conditions for olives in Andalusia, especially given that yield would have been higher still if the data for the 4 th year after planting was included.…”

“…Although there are no reports on the area cultivated with hedgerow olives, the practise is increasing rapidly in various countries such as Spain (Navarro and Parra, 2004;Tous et al, 2007), Italy (Godini et al, 2006), Morocco, Tunisia and the United States (Berenguer et al, 2006). However, very few experiments have been reported on the best conditions and viability for this type of olive orchard (Pastor et al, 2005;De la Rosa et al, 2007;Tous et al, 2007).…”

“…Different olive cultivars exhibit different vigour levels, but a true dwarf cultivar or dwarfing rootstock does not exist. The primary cultivars used in high density systems tend to be very precocious, such as 'Arbequina', 'Arbosana' or 'Koroneiki' (De la Rosa et al, 2007;Tous et al, 2007), but they can not be considered to be low vigour cultivars. Tree vigour could be a problem in very favourable growing conditions, such as that in Andalusia, southern Spain, since hedgerows must be kept below certain dimensions to allow harvesters to pass over the top of the row.…”

A new type of olive (Olea europaea L.) orchard, based on high-density hedgerows harvested by vineyard type straddleharvesters has appeared in recent years. This system greatly simplifies olive harvesting, which has a high labour demand in standard olive orchards. There are, however, no specific low-vigour olive cultivars or dwarfing rootstocks adapted to this system, as exist in other fruit crops. It is therefore crucial to select the optimum density for maximum production without causing serious competition problems. In this study we present initial results of the effect of densities, ranging from 780 to 2,580 olive trees ha-1, on the production of an ‘Arbequina’ olive hedgerow orchard during the first seven years after planting. There were no significant differences in fruit characteristics (oil content and moisture) among density treatments. Density had a linear negative influence on fruit yield tree-1. In contrast, accumulated yield ha-1, for both fruit and oil yield, showed a linear increase with increased density, with coefficients of determination ranging from 0.37 to 0.72. Accumulated oil yield at high density was up to 5,000 kg ha-1 more than at the low density

“…Heavy pruning is required for most standard cultivars to control canopy size and tree architecture. The removal of many newly developed shoots to control the hedge size decreases the potential yield while the remaining branches tend to thicken more rapidly and limit the efficient use of the over-head harvesters (Dag et al, 2006;Tous et al, 2008). Thus, the overall long term production of the high density hedgerow orchards is generally not higher than the production in parallel more spaced shaker harvested intensive orchards.…”

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...
