Olive groves are one of the most important agro-systems in Mediterranean basin, and Andalusia region produces highest quantity olive oil Europe. The aim this work was to evaluate long-term (15 years) influence two management practices orchards—conventional tillage (CT) no with bare soil herbicide application (NT + H)—on physical properties, infiltration capacity, erosion rates, productivity. In...

The high level of copper (Cu) accumulation in the soil, risk surface water contamination, and potential public health problems due to Cu entering food chain have raised concerns on use compounds agriculture, including olive growing. As a consequence, there is worldwide regulatory pressure agricultural systems limit compounds. Hence, field trial was carried out evaluate effectiveness low contain...

The use of a controlled-release fertilizer (CRF) was studied in traditional rainfed olive grove Mediterranean climate where precipitation is very irregular, particularly the spring. objective study to assess whether CRF can improve tree's performance compared conventional nitrogen (N) (CF), by supplying N gradually and reducing risk potential loss from leaching. fertilized treatments showed bet...

The Kingdom of Saudi Arabia is considered to be one the world leaders in olive production accounting for about 6% global production. Given fact that 94% groves are mainly rain-fed using traditional methods production, annual witnessing a noticeable fluctuation which worse due infectious diseases and climate change. Thus, early effective detection plant both required urgent. Most farmers use met...

A study was conducted to determine suitable soil properties as soil quality indicators, using factor analysis in order to evaluate the effects of land use change on loessial hillslope soils of the Shastkola District in Golestan Province, northern Iran. To this end, forty surface soil (0-30 cm) samples were collected from four adjacent sites with the following land uses systems: (1) natural fore...

The olive fruit fly, Bactrocera oleae (Rossi), is an economically important and endemic pest in olive (Oleae europae) orchards in Turkey. The aim of this study was to determine olive fruit fly infestation in different olive cultivars in the laboratory. Olive fly infested fruits were collected in Çanakkale province to establish wild fly population. After having reproductive olive fly colonies, 1...

So far the limited knowledge about diet of omnivores and generalist predators in olive groves has not allowed clarification their role as natural enemies. Stable isotope (δN15 δC13) analysis is a useful tool for predicting trophic position high number species, variety basal resources flux energy food web. We have explored possible consumers two important pests grove: adults Prays oleae Bern (Le...
