Abstract
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.
Highlights
The Ziban region is one of the most important phoenicultural regions in Algeria, by production of dates; and on the quality scale of the famous Deglet Nour date [1].The Deglet Nour date, export variety par excellence, represents 53.56% of the national production in dates
Our work aims to characterize the effect of some hydro-edaphic properties on the quality of Deglet Nour dates, produced in some palm groves in the Biskra region
The objective of our work is to study of the influence of some hydro-edaphic characteristics on the characteristics of Deglet Nour dates in the Biskra region
Summary
The Ziban region is one of the most important phoenicultural regions in Algeria, by production of dates; and on the quality scale of the famous Deglet Nour date [1].The Deglet Nour date, export variety par excellence, represents 53.56% of the national production in dates. The Bikra region provides 49.38% of the national production in Deglet Nour [2]. According to [3,4], the quality of dates is influenced by the type of cultivar and by environmental conditions. Our work aims to characterize the effect of some hydro-edaphic properties on the quality of Deglet Nour dates, produced in some palm groves in the Biskra region
