BACKGROUND Super-intensive cultivation facilitates olive mechanized harvesting, allowing substantial savings in the production cost of virgin olive oil (VOO). However, the number of varieties adapted to this type of cultivation is small. This study explores the impact that harvesting with a grape straddle harvester of 'Manzanilla de Sevilla'...

Fertigation is widely used in the new intensive olive orchards, although, there is not enough information for a rational management of this practice. Preliminary results of an fertigation experiment iniciated in 1999 in a mature olive orchard of the cultivar 'Manzanilla de Sevilla' are presented. Four treatments were established: T1(no...

Agronomic practices can modify olive fruit and oil quality. However, there is little information on the influence of fertigation, a common practice in most intensive orchards. We studied nutrient distribution in the soil profile following fertigation with different doses of N-P-K fertilizer, and its effect on nutrient concentrations, yield and...

We report the results of a study carried out in a 'Manzanilla de Sevilla' olive orchard near Seville, Spain, where the influence of different fertigation treatments on oil chemical composition was considered. Four treatments were established: control (no fertilizer) and T200, T400, and T600 in which each tree, respectively, received 200, 400,...

El cultivo del olivo en Ar-gentina tiene su origen en la colonización española, sien-do en la localidad de Arauco (La Rioja) donde se realiza-ron las primeras plantacio-nes. Queda el Olivo Cuatri-centenario como testigo de aquella época (Foto 1). El desarrollo del cultivo no tuvo lugar, sin embargo, hasta finales del siglo XIX, como...

Old traditional cultivars are valuable genetic resources for crop improvement, but a great number of them have disappeared in the past century. This study aimed to characterize traditional cultivars of different Prunus species collected in small family orchards in southwestern Spain and to evaluate their genetic diversity and relationships....

The olive tree is well adapted to the Mediterranean climate, however, the current increase in temperature as a consequence of the global warming affects the phenological stages and can accelerate the ripening of the fruits, moving the harvesting to periods that are less favorable for quality production. In this work, the impact of harvesting...

BACKGROUND Mechanical harvesting with over-the-row harvesters in super-high-density (SHD) table olive orchards increases the effectiveness of fruit removal, although bruising can limit the fruit quality. Additionally, an early harvest in periods less favourable to quality production is increasingly frequent as a result of global warming. The...

At a time of increasing demand, the extremely high cost of manual labor required to harvest fruit in table olive groves is limiting the economic survival of the crop in many producing countries. New grove designs and management practices such as superhigh-density (SHD) groves now in use in oil olive production should be explored as an option to...

Andalucía es la segunda región productora de cítricos de España, teniendo por tanto una extraordinaria importancia económica y social. Sin embargo, la cadena de valor de los cítricos comprende un sector productor bastante atomizado frente a unos compradores muy concentrados y organizados, y un mercado poco transparente. El objetivo de esta...

Table olive quality was analyzed in adult 'Manzanilla de Sevilla' olive trees subjected to different N–P–K fertigation treatments through five years (1999–2003). A randomized block design with four fertigation treatments was established: irrigated without fertilizer (control), and T200, T400, and T600 treatments, in which each tree was ...

Near Infrared (NIR) spectroscopy was evaluated as a fast and easy method for identifying the most interesting cocoa genotypes according to chemical composition, including bioactive compound contents, in more than 80 samples of cocoa beans from the Mexican Germplasm Bank, which were harvested over three years. Clear dif ferences in chemical...

Las plantaciones superintensivas de olivar (Olea europaea L.), con densidades superiores a los 1.000 árboles por hectárea, se han convertido en una interesante alternativa al cultivo de olivar de almazara en la que el coste de recolección disminuye por la drástica reducción de la mano de obra y del tiempo requerido por el empleo de cosechadoras...

Sexual reproduction in olive is carried out for purposes such as breeding. The seedlings evolve from the juvenile to the adult stage, and until now, only the discrete developmental phases have been investigated in detail. However, the transition process has been poorly studied in fruit trees, especially in olive. In this paper, juvenile to...

Actualmente el sector del olivar en España incluye dos subsectores claramente diferenciados por su aprovechamiento: el olivar de almazara y el de mesa o verdeo, cada uno con unas particularidades específicas que los diferencian, tales como variedades empleada s y técnicas de cultivo como la poda o la recolección. En los últimos años, la...
