Among the main pollutants generated by industrial activities, heavy metals such as zinc and copper pose particularly worrying problems. Indeed, these elements are inherently non-biodegradable.
This work investigates the ...
Faced with growing environmental challenges, demographic pressures, and ever-increasing food needs, global agriculture is facing a profound transformation. In this context, the intensive use of ...
This study was carried out to evaluate the effect of chemical fertilization on the growth and productivity of zucchini (Cucurbita pepo). The experiment compared two treatments: a control without fertilization (T0) and a ...
The Pédoclimat approach is a fundamental tool for the rational and sustainable development of an agricultural farm at the Abdel amid bin Badis university a mostaganem. It is based on the joint analysis of soil characteristics ...
Land surface temperature (LST) is an important indicator for studying climate change, heat balance, the urban environment, and hydrological and agricultural processes. LST is a key variable to be retrieved from Landsat ...
This study was conducted from April 15 to May 18, 2025, in several laboratories, including the
Biochemistry and Microbiology Laboratory of the Faculty of Natural and Life Sciences at Abdelhamid
Ibn Badis University of ...
In Algeria, most agricultural lands are characterized by sandy soils with low organic matter content, which considerably limits their productive potential. This limitation is particularly evident in the Mostaganem region. ...
The research focused on the extraction and utilization of sunflower oil (Helianthus Annuus), highlighting its physicochemical characteristics and its use in soap production. The use of a Soxhlet apparatus with an organic ...
The use of biofertilizers in agriculture has become an environmental and economic reality.
This study evaluated the effect of Azolla, alone or combined with NPK, on two tomato
varieties (Ksi-Rosa and Sereen F1). The ...
A study was conducted on the simultaneous adsorption of the cationic dyes methylene Blue

Le présent mémoire est d’abord une enquête de compréhension globale des systèmes d’élevage ovin en Algérie et, particulièrement, des élevages familiaux. C’est un constat simple bien sûr mais nécessaire : l’élevage ovin ...
This research is part of a biological control approach by testing the bioinsecticide effect of hydroethanolic extracts of dry leaves from two plant species: Pinus pinaster (maritime pine) and Rosa sp. (rose), targeting ...
Tomato (Lycopersicon esculentum Mill.) is one of the most widely cultivated and consumed vegetables in the world. It is particularly vulnerable to fungal infections, especially those caused by Alternaria sp.and Fusarium ...
Citrus anthracnose, caused by Colletotrichum sp., is a fungal disease that can cause considerable damage to citrus trees. If not treated promptly and effectively, it can reduce crop yields. However, there are general ...
Meat is an essential nutritional source, rich in proteins, minerals, and vitamins. This study aims to assess the effect of animal species on the physico-chemical composition of meat, focusing on two types: beef and sheep ...
The objective of this dissertation is to study the morphological characteristics of the Ouled Djellal sheep breed, conducted at the Si Mourad farm. The Ouled Djellal breed, known for its robustness and adaptation to arid ...
The present study focuses on the in vitro and in planta antifungal activity of two different species of Trichoderma sp. on Colletotrichum sp., the causal agent of anthrachnosis, using two methods : direct confrontation and ...
This thesis examines the effect of lactation stage on the physicochemical quality of cow's
milk, focusing on the biological and physiological variations that influence milk
composition. It begins with an in-depth review ...
This study aims to evaluate the influence of animal species on the physico-chemical characteristics of milk. Three types of milk were compared: cow, goat, and camel. The analyses focused on pH, acidity, density, lipids, ...
