Impact des eaux d’irrigation sur la culture du palmier dattier dans la région d’Adrar

Abstract

The study carried out in 12 plots with gravity irrigation system in the region of Meraguene la Wilaya of Adrar. This study aims to know the effects of irrigation water on the physicochemical properties of soils and to do sowed have contributed to the spatial-temporal analysis of these properties for each soil and water sample Taken fromirrigated plots. This work aims to study the physic-chemical characteristics of soils and irrigation waters. Similarly the morphology of the date palm and the yield in dates. The results obtained after physic-chemical soil and water analyzes show that the irrigation waters are very saline (3.31 ≤ EC ≤ 3.6), with a slight alkaline pH varying between (6.13 ≤ pH ≤ 8.14), a level which Varies from one parcel to another. Soil exhibit morphological and analytical variations characteristic of high salinity (0.39 ≤ CE ≤ 4.49) and an alkaline pH varies between (8.6 ≤ pH ≤ 9.12). We can say that the salinity of the soil and the quality of the irrigation water may have had an adverse effect on the yield of the date palm and its morphology.
