ETUDE DE L’EFFICIENCE DU SYSTEME MESKAT ENVERS LE COMPORTEMENT AGRONOMIQUE D’UNE OLIVERAIE ADULTE (TUNISIE LITTORALE SEMI-ARIDE)
Journal Title: Larhyss Journal - Year 2015, Vol 21, Issue 21
Abstract
In order to study the impact of Meskat system on adult olive trees, an experimental device was selected in the region of Kroussia (M'Saken, Sousse, Tunisia). This study area corresponds to three stripes ; each one is composed by four compartments. The study focused on six agronomic parameters of an adult olive grove, variety of "Chemlali", including canopy volume, foliar surface of elderly leaves, foliar surface of young leaves, leaf stomatic conductance, fruit diameter and fruit length. These parameters were evaluated experimentally in situ and/or laboratory with two repetitions per trap. The results have shown the positive impact of the system on the agronomic behavior of the considered olive trees. These findings concerned, mainly, the canopy volume, foliar surface of elderly leaves, foliar surface of young leaves and leaf stomatic conductance, with a recorded improvement of 51, 25, 37 and 50%, respectively.

L'INTERET DU CALCUL DES PERTES DE CHARGE EN MICRO IRRIGATION
Les exemples traités permettent de constater que la micro-irrigation est tributaire du dimensionnement, lequel est influencé par les méthodes de calcul utilisées. La corrélation entre la plus value générée par...
FIRST APPLICATION OF THE COP METHOD TO VULNERABILITY MAPPING IN THE MEFFROUCH CATCHMENT (NORTHWEST OF ALGERIA)
This paper presents the first application of the COP method for the vulnerability mapping in Mefrouch catchment (Tlemcen, Algeria). This method has been developed for the intrinsic vulnerability of carbonates aquifers...
PERTE DE CAPACITE DANS LES BARRAGES SITUES DANS LES ZONES ARIDES ET SEMI ARIDES. CAS DES BARRAGES DE GARGAR, BOUHANIFIA, OUIZERT ET FOUM EL GHERZA
Most dams are subject to a loss of capacity due primarily to three factors namely: water leakage, the silting and evaporation intense. The study of these phenomenons is of great importance because they can endanger the...
