In a grove in north-eastern Morocco 2020, severe root rot and crown symptoms were noticed on olive trees (Olea europaea). Pythium schmitthenneri was identified as the pathogen based conidia morphology cytochrome oxidase subunit II (COXII) gene sequence analysis. Koch's postulates verified by re-isolation of fungus P. from artificially inoculated seedlings after pathogenicity test. This is first...

There is an urgent need to conserve and improve the quality of agricultural soils in coming decades. Decision tools capable providing reliable information about soil are needed, index (SQI) one most used. Principal component analysis (PCA) common methodology calculate it, however some cases fails differentiate properly. Therefore, aim this work assess a SQI through different as network (NTA) co...

nearly just a decade ago, olive leaf moth, palpita unionalis, was identified as an exotic pest from an olive grove in roodbar, iran. in order to plan an ipm programme regarding olive, a series of laboratory and field studies were carried out during 2001-2003 in qazvin province. to study the emergence time, number of generations, feeding behaviour and developmental periods at field, five trees (...

Herbicides are the main type of pesticides causing water contamination. The chloroacetanilide herbicide Smetolachlor is frequently detected in ground and surface waters, and represents a potential source of water pollution. The addition of organic residues to soils to reduce losses of organic pollutants constitutes sometimes an efficient method to control contamination. One of the recent techno...

Understanding how small mammals (SM) are associated with environmental characteristics in olive groves is important to identify potential threats agriculture and assess the overall conservation value functioning of agro-ecosystems. Here, we provide first insights on this topic applied traditional northeast (NE) Portugal by assessing landscape attributes that determine SM occurrence, focusing on...

The common use of soil-fertility control data in Croatia includes properties such as soil pH, organic matter content and plant-available phosphorus (P) and potassium (K) extracted by ammonium lactate (AL) solution. These data are commonly used for fertilizer recommendations for both field vegetable (Lončarić et al., 2003) and arable crops (Vukadinović et al., 1996). Also, the same soil data hav...

Soils have the capacity to store three times more carbon (C) than atmosphere. This fact has focused scientific and governmental attention because it is one way mitigate climate change. However, there comes a time when of soils C reaches limit, considering soil organic (SOC) saturation. In Mediterranean area, agricultural are traditionally exposed conventional tillage (CT), causing properties qu...

The new high-density cropping systems (>1200 trees ha) represent a very interesting proposal for olive orchard profitability. It is crucial to know the morphology and the dynamics of sprout elongation of a cultivar in order to fully assess its suitability for a high-density olive orchard. For this reason we planned a research on two cultivars, Coratina and Arbequina, in a high-density orchard. ...

Nitrogen (N) fertilization has been extensively studied all over the world, not only due to its impact on plant growth and yield, but also product quality. Olive oil is a natural highly valued by markets, role in Mediterranean diet, when quality above legally established standards. Thus, it important continue study how cropping practices can of olive order fine-tune guidelines issued producers....
