Index. décimale : 630.32 Résumé : Les poudres des feuilles et les huiles essentielles extraites de deux plantes médicinales de la région de Tlemcen ont été testées dans des conditions de laboratoire à différentes doses sur un insecte coléoptère de la famille de curculionidés sitophilus oryzae. ces poudres des feuilles et huiles essentielles présentent une activité insecticide et entraînent chez les adultes des insectes étudiés une réduction significative du nombre d'individus par rapport à celle dans le témoin. Les rendements des plantes médicinales en huiles essentielles est de 0.43% pour la Lavande et de 0.16% pour le Thym. En huile essentielle c'est la Lavande qui tue plus que le Thym. Par contre pour la poudre c'est le Thym qui fait le plus mortalités que la Lavande.

Index. décimale : 630.03 Résumé : The use phytosanitary produts raises many concerns related to the environment and human health. currently, medicinal plants have a major advantage to the progressive discovery of the applications of their extracts in biological, control, presenting potential as a source of bioactive naturalmolecules.
The present study assessed the bio-insecticidal activity of aqueous extracts formulated from urtica dioica against the Tribolium Castaneum beetle.
The results of this study showed that the various nettle-based phytopreparations demonstrated toxicity on the target pests for both treatments: by direct and indirect contact.This toxicityvaried with dose and time. The mortality rate was quite considerable; the direct contact treatment is more toxic than the other method, with a fairly high mortality rate after 72 hours.
Our extract showed a 100% mortality rate after 72h for the 100% concentration.Activité insecticide des extraits aqueux de l'ortie dioïque (Urtica dioica.L) sur Tribolium castaneum [texte imprimé] / Nour El Houda Hammadi, Auteur ; Marwa Saidani, Auteur ; Asma Djidel, Auteur . - Tipaza [Algérie] : Centre universitaire Morsli Abdellah - Tipaza-, 2023/2024 . - p.61 : couv. en coul., ill., fig. ; 30 cm + CD.

Titre : Analyse dianostic des performances hydrauliques dans la pratique de l'irrigation par système goutte à goutte dans la Mitidja Ouest Type de document : texte imprimé Auteurs : Manel Amara, Auteur ; Mohamed El Amine Tifoura, Auteur ; Abdelkrim Ould Rebai, Auteur Editeur : Tipaza [Algérie] : Centre universitaire Morsli Abdellah - Tipaza- Année de publication : 2024/2025 Importance : p.74 Présentation : couv. en noir et blanc ., ill., fig.,tabl.

Index. décimale : 630.14 Résumé : The adoption of drip irrigation in the Mitidja west region has accompanied the development of a market-gardening basin supplying the whole country. However, despite the support programmes that have been launched, little is known about the conditions of use and control of this technique, particularly irrigation performance. This study aims to ases performance at different scales (boom,sector and farm) by establishing analysing pressure (P) and flow (Q) variability profiles, and then the Q-P relationship. To do this, a preliminary survey was carried out among 15 farmers, in conjunction with local authorities and system installers, with the aim of taking into account the connditions of adoption, installation and use. Then 3 farms were selected fom the 15, on the basis of a typology established according to the results of the survey.A total of 288 flow measurements and 176 pressure measurements were taken (repeated 3 times).
The best reslts (∆P≤0.2 bar; DU≥89%, flow rate staility and compliance with ISO 9261 and ASABE standards) were obtained in the operation involving an installation withe the same boom diametr and the same type of integrated self-regulating drippers. It was installed by a fairly well-trained and experienced installer in the field. Another farm, on the other hand, showed the least satisfactory results, with fairly significant instability in the flow rate, with rates as high as DU<61%t ∆P>69%. This installation was carried out workers with 3to 5 years experience in using the system, using booms of different diameters and lengths and different type of non-self-regulating drippers, both integrated and in-line. The distance from the station head also seems to have an effect. This study represents a contribution to the evaluation of drip irrigation performance. On the one hand, it highlihts the importance of the elements included in the analysis relating to the installation and use of the system, but on the other hand it also opens up new perspectives, in particular integrating other components not taken into consideration.Analyse dianostic des performances hydrauliques dans la pratique de l'irrigation par système goutte à goutte dans la Mitidja Ouest [texte imprimé] / Manel Amara, Auteur ; Mohamed El Amine Tifoura, Auteur ; Abdelkrim Ould Rebai, Auteur . - Tipaza [Algérie] : Centre universitaire Morsli Abdellah - Tipaza-, 2024/2025 . - p.74 : couv. en noir et blanc ., ill., fig.,tabl. ; 30 cm + CD.

Titre : Analyse et inventaire de l'utilisation des intrants phytosanitaires dans la région de Tipaza Type de document : texte imprimé Auteurs : Bouyengoulene Nousra, Auteur ; Asma Djidel, Auteur Editeur : Tipaza [Algérie] : Centre universitaire Morsli Abdellah - Tipaza- Année de publication : 2024/2025 Importance : p.74 Format : 30 cm Accompagnement : CD Note générale : Bibliographie: p53-64.
Annexes: p65-63.Langues : Français (fre) Catégories : Agronomie Mots-clés : Pesticides chemical inputs vegetable farming tomato pepper Tipaza. Index. décimale : 630.38 Résumé : The use of phytosanitary inputs has become essential in modern agriculture, despite raising major sustainability concerns. In this context, a survey conducted among 40 vegetable farmers in the Tipaza region highlighted the main trends in plant protection practices for tomato and pepper crops. The majority of respondents (65%) are between 30 and 50 years old, with limited representation of older farmers. Most have significant agricultural experience: 90% have been farming for over 10 years. Education levels remain modest, mostly limited to middle school, and 90% have not received any specialized training in agriculture. Farms are generally small (less than 1 hectare), with three cropping periods practiced, and more than half of the farms operate under greenhouses. Drip irrigation is widely used. Fertilization is predominantly chemical, with few soil analyses conducted. Crop rotation is common, though often poorly implemented. Tomato and pepper crops face various biotic and abiotic constraints: Fusarium, leaf miners, mites, and late blight are most prevalent in tomatoes, while thrips, Fusarium, and late blight dominate in peppers, along with occasional outbreaks of other pests and diseases. Pesticide use is intensive, mainly involving fungicides and insecticides. Nearly 98% of farmers apply treatments preventively, and 80% follow recommended dosages. However, most do not use protective equipment, disregard pre-harvest intervals, and manage pesticide waste poorly. While all farmers express a desire to reduce pesticide use, 97.5% foresee an increase in usage due to climate change. Only 7.5% have participated in awareness or training initiatives, highlighting the urgent need to strengthen farmer education, promote safer practices, and conduct further studies to better manage pesticide use in the face of climate change and anticipate future developments.

Titre : Analyse et optimisation de l'efficience eau-énergie du mini pivot artisanal Type de document : texte imprimé Auteurs : Imene Medjadji, Auteur ; Haithem Messaoud, Auteur ; Abdelkrim Ould Rebai, Auteur Editeur : Tipaza [Algérie] : Centre universitaire Morsli Abdellah - Tipaza- Année de publication : 2024/2025 Importance : p.58 Présentation : couv. en noir et blanc ., ill., fig.,tabl. Format : 30 cm Accompagnement : CD Note générale : Bibliographie: p47-53. Langues : Français (fre) Catégories : Agronomie Mots-clés : artisanal mini-pivot irrigation efficiency water distribution remote sensing Tipaza. Index. décimale : 630.16 Résumé : Agrarian dynamics in Algeria have been accompanied by the adoption and adaptation of imported models, particularly for irrigation. Little is known about the efficiency of these local irrigation systems, which is a limiting factor in terms of controlling and improving water use at plot level, despite the considerable transfer of technology. The aim of the present work is to study the efficiency of the artisanal mini-pivot, installed in a new context of use in Tipaza, with a view to proposing improvements. To this end, an approach was adopted combining three scales of analysis, namely (i) analysis of the evolution of CUD water distribution under mini-pivot following an experimental protocol (ii) monitoring, modelling and mapping, by means of sampling and remote sensing, of the H% soil moisture status (iii) mapping of water use efficiency at plot scale. Our results show that the mini-pivot has a CUD, below the recommended threshold, which decreases under the effect of wind and pressure, i.e. a rate between 57% and 71% for the different trials. As a result, an asymmetry in moisture evolution is apparent, depending not only on CUD but also on soil characteristics. Combining the results of the two components UD and H% by means of mapping also reveals low irrigation efficiency (10% - 50%), at plot level, with sub-zones ranging from average to good (75% - 94%). It is therefore recommended to adapt a busage according to the characteristics of the terrain and to include other characteristic soil parameters for further analysis. This work represents a contribution to the field of irrigation and is part of a global context of water control and saving in the face of very frequent water stress situations.
