Effect Of Soil And Water Salinity On The Quality Of Deglet Noor Dates in Biskra Region, Algeria

Résumé

The Biskra region in Algeria is known for the production of very good quality Deglet Nour dates. This quality is the result of the interaction of several ecological and agronomic factors. Our work aims to study the impact of hydro-edaphic parameters on the quality of Deglet Noor dates, produced in the region of Biskra. The study is carried out in three stations: Tolga, Sidi Okba and Ouled Djelel. Three farms are chosen in each station. The methodological approach is based on Soil, water, biometric and biochemical analyzes on sampled dates. The results shows that the water irrigation have a high salinity in Sidi Okba station. The statistical analyzes (ACP) shows that, the high salinity of irrigation water is the main cause of soil salinization. This salinization reduces the biometric characteristics of dates (length, width and weight), and increases their total sugar content.
