The objective of the current study is to evaluate the effects of nitrogen rate N on tree growth, fruit yield and quality of clementine Nules variety, budded on Flhorag and Carrizo citrange rootstocks, grown on clay soils at the Experimental station of Sidi Allal Tazi, INRA Morocco, over five seasons. The experiment has been carried out in a split-p...

Mineral nutrition is one of the most important components of citrus production management. The volume of production and fruit quality are closely related to mineral nutrition given to citrus trees. The objective of the present study was to evaluate the effect of different nitrogen, phosphorus and potassium levels on yield, fruit size, fruit weight...

Purpose: Soil salinization is one of the most severe abiotic stresses which threaten sustainable agriculture in arid and semi-arid regions including Morocco. The application of organic amendments like composts to saline soils has been confirmed to alleviate soil salinity stress. The present work aims to study the effect of humic acids (HA), as one...

Identifying the respective role of environmental, landscape and management factors in explaining the patterns in community composition is an important goal in ecology. Using a set of 32 temporary ponds in northern Morocco we studied the respective importance of local (within the pond) and regional (density of ponds in landscape) factors and the imp...

The impact of grazing on the vegetation of Moroccan temporary pools has been studied at 2 scales: regional (inter-pools) and local (intra-pools). Half of the 16 forest pools studied is located in a reserve and ungrazed. The other half, located within public forest, is grazed. Vegetation relevés coupled to water-depths measurements were carried out...
