Abstract

The Annaba area hosts in its underground a water potential of great importance. In fact, it is one of the Algerian plains where groundwater is subject to over-pumping. Moreover, the expansion of farmlands and the development of the neighboring agglomerations required a massive pumping of water, thereby leading to the change in hydrodynamic regime of groundwater and to the degradation of its quality. On the basis of boreholes and physico chemical data, the three major factors responsible for the evolution of chemical quality of water observed at the aquifer were identified: (1) mineralization due to natural and anthropocentric processes (responsible for the increase in the contents of chlorides, sodium, calcium and magnesium), (2) the oxydo reduction conditions due to the passage of the water table from an unconfined aquifer or even semi confined to a confined aquifer (responsible for the reduction of nitrates and (3) pollution of groundwater by nitrates in areas where the water table is shallow and in the absence of a protective clayey cover.

Paluku Augustin, Tsobeng Alain, Okungo Albert, Tchoundjeu Zacharie, Bwama Marcel and Van Damme Patrick wrote a research paper on Anonidium mannii entitle of “Vegetative propagation of Anonidium mannii (Oliver) Engler & Diels (Annonaceae) by leafy stem cuttings in Kisangani, DR Congo“

This study tested the influence of substrate type, size surface and application of IBA auxin on rooting of stem cutting leaf of Anonidium mannii, a wild fruit species with low seed germination rate. Two trials were conducted. The first tested three substrate types that are sand, wood sawdust and rice husks. We also tested combinations of these substrates (2:2), resulting in six treatments in a randomized complete block design.

The goal of this investigation was to evaluate some qualitative and quantitative traits in fruits of five tomato (Lycopersicum esculentum) cultivars. These traits were vitamin C content, pH, total soluble solids (TSS), titrable acidity, fruit diameter, fruit volume, fruit firmness, fresh weight and dry weight. Studied cultivars were Matin F1, Yaghoot, Sunseed, Sadeen and Raha. The results showed that there were significant differences in evaluated parameters among cultivars. The highest contents of vitamin C (36.32 mg. 100 g-1), diameter (6.77 cm), volume (221.25 cm3), firmness (2.45 Kg. cm-2), fresh weight (194.29 g) and dry weight (11.3 g) were belonged to the cultivar Sunseed. The highest pH (4.3) and TSS (2.49 %) were belonged to the cultivars Yaghoot and Matin F1, respectively.

Influence of maize varieties CLH103 and SHABA on the effectiveness of FossilShield® and SilicoSec® against Sitophilus zeamais was evaluated in laboratory. Each product was used at 0, 0.5, 1, 1.5 and 2 g/kg and four exposure periods (1, 3, 7 and 14 days) for adult mortality and F1 progeny production.
