El olivar es un cultivo tradicional de secano pero su buena respuesta al riego lo ha convertido en el cultivo con mayor superficie regada de España. Sin embargo, la escasez del agua y la competencia con otros usos sociales e industriales ha producido una reducción en los recursos hídricos disponibles. Esto supone que el ...

El agua es un recurso natural escaso muy importante en las prácticas agrícolas. Aunque las superficies en riego a nivel mundial están en torno al 17% de la superficie agrícola total, éstas representan más del 40% de la producción mundial (Fereres y Evans, 2006). El aumento en la producción agrícola, por el uso del agua en la agricultura, ha...

La variación del diámetro del tronco es un sistema que se está sugiriendo para la programación del riego de varias especies frutales pero que no tiene resultados claros en olivo. El parámetro de estos ciclos más tradicionalmente empleado es la máxima contracción diaria (MCD). En este trabajo se pretende analizar los posibles causantes que...

En este vídeo se explica una técnica agronómica de programación de riego deficitario en base a medidas de estado hídrico en planta. El indicador que se usa es la variación del diámetro del tronco. Esta medida, basada en dendrometría, permite la monitorización continua y a distancia del cultivo. Permitiendo un ajuste del riego diario, basado en...

In this work we tested techniques suitable for a future validation of the RATP model to simulate transpiration and photosynthesis of mature olive trees under field conditions. Canopy architecture was characterised with an electromagnetic 3D digitiser and the software 3A. Although the capability of the software to deal with big data sets has to...

La programación del riego deficitario controlado (RDC) es una necesidad derivada de la escasez de agua disponible para el riego. La resistencia al estrés hídrico de los diferentes estados fenológicos en olivar está bastante bien documentada pero no así los niveles de estrés hídrico. El objetivo de este trabajo es sugerir en base a experimentos...

– Influence de l'irrigation partielle du sol sur les paramètres des relations hydriques de l'olivier. Une comparaison de l'irrigation goutte à goutte avec l'irrigation en cuvette a été conduite sur oliviers 'Manzanilla' âgés de 30 ans plantés à 7 m 5 m dans un verger du sud-ouest de l'Espagne. À la fin de la saison sèche de 1998, nous avons...

Olive trees (Olea europea L) are traditional Mediterranean specie. The agricultural management of olive orchards has been changed from 90's of the last century. The most important change is the great increase of the irrigation surface. This new water demand has been produced in water scarcity areas. Such conditions and the traditional...

Maximum daily trunk shrinkage is a common measurement in irrigation scheduling of fruit trees. But the strong relationship between these measurements and the environment severely limit field applications. Reference baselines are the solution for understanding the influence of environmental conditions. Nevertheless, the extrapolation out of the...

Regulated deficit irrigation (RDI) results are affected by the actual water stress level reached during the treatments. The irrigation scheduling based on water status measurements, such as trunk diameter fluctuations, can control in an accurate way the water restrictions. However, the number of works that use these indicators as isolate...

© 2014 Elsevier B.V. Pit hardening period is the phenological stage when water stress is recommended in regulated deficit irrigation (RDI) in olive trees. In table olive trees, fruit growth is a very important process which could affect the final profit of the yield. RDI scheduling based on water status measurements could improve water...

Deficit irrigation scheduling needs accurate indicators and in recent decades, continuous plant indicators have been developed. However, threshold values that could be useful in commercial orchards are not commonly reported. The water potential is a discontinuous measurement commonly used as a reference in the description of water stress level....

La agricultura de riego es actualmente el mayor consumidor de agua en el mundo (Fereres y Evans 2006)). En muchas zonas áridas y semiáridas la escasez de recursos hídricos junto con la creciente demanda de agua para otros usos están imponiendo una fuerte presión para limitar su disponibilidad en la agricultura, un ejemplo muy claro es el caso...

Water scarcity is generating an increasing interest in deficit irrigation scheduling. The trunk diameter fluctuations are daily cycles that have been suggested as tools for irrigation scheduling. The trunk growth rate (TGR) was suggested as the best indicator for olive trees during pit hardening. The aim of this work is to clarify how the TGR...

The aim of this work was to evaluate, for an olive orchard in the Aljarafe county, the method developed by Orgaz et al. (2005) for determining the crop evapotranspiration (ETc). We compared the calculated ETc (ETc Orgaz) values with those determined by the crop coefficient approach (ETc crop coef), as described by Fernández et al. (2006), who...
