Evaluation of the Performance of a Composite Material Made From Lateritic Soil, Crushed Granite, and Cement for Use as the Base Layer of Road Pavement
Etienne Malbila, Lorell Bationo, Adélaïde Lareba Ouedraogo, Hamma Fabien Yonli, Sié Kam, Dieudonné Joseph Bathiébo
The base layer is important for the road pavement structural performance. This study aims to monitor the performance of various local composite materials as road construction materials. To do this, an experimental study treated the improvement of geotechnical properties of a lateritic gravel, initially nonadopted as a base layer, by using thre(...)

Description de la femme dans le roman burkinabè : cas de Roogo de Mahamoudou Ouédraogo
SAWADOGO Somaïla, BELEM Hamidou
L’œuvre littéraire est porteuse des valeurs et des identités de la société décrite par son auteur. Ainsi, le roman, à travers ses intrigues, mobilise des personnages véhiculant des idées, des visions, des philosophies. Ce faisant, l’auteur met en exergue l’image des personnages. La littérature burkinabè s’inscrit dans cette logique avec une mi(...)

Experimental study on the use of crushed granite sand for lithostabilization of lateritic soils in road construction
Yasmine Binta Traoré, Possibo Elise LOMPO, Nafissatou Savadogo, Hamma Fabien Yonli
The use of local materials in road infrastructure provides a sustainable alternative to the high costs of conventional construction materials. However, certain lateritic gravels exhibit insufficient geotechnical properties for direct use in pavement layers. This study evaluated the potential improvement in the physical and mechanical propertie(...)

Production and evaluation of two biofertilizers on vegetative growth of sweet potato (Ipomea batatas L.) in Benin.
M.O.E Faton, H. Soura, A. Hounkpevi, B. Yessoufou, Z. Bonou-Gbo, A.H.G. Akueson, and L.S. Gnancadja.
Sweet potato (Ipomoea batatasL.) is a key crop for food security in many developing countries, including Benin. Despite its potential for high yield and nutritional value, the productivity of sweet potato in Benin remains limited, primarily due to soil fertility challenges and inadequate fertilization pr(...)

Land Use Dynamics and Forage Availability of Pastures in Southwest Burkina Faso
NOUGTARA Somnoma, YAMEOGO Augustin, BAMBARA T. Ghislain b, KIEMA André, SOUDRE Albert and TRAORE Kanwoué
Land is subject to various uses aimed at meeting human needs for crop and livestock production as well as infrastructure. These multiple uses and demands make land occupation dynamic. To understand this dynamic and its potential impacts on livestock activities, the present study was conducted in the area of Batié. It aimed to examine the condi(...)

Improving of the Clarke and Wright’s Heuristic for Solving Multiobjective Vehicles Routing Problem
Issouf Nikiéma, Joseph Poda, and Kounhinir Somé
In this paper, we propose a new multiobjective model for the Capacitated Vehicle Routing Problem with a single depot. On one hand, the model aims to optimize multiple conflicting objectives, such as minimizing the total travel distance and reducing the number of vehicles used. On the other hand, we develop a heuristic approach to effectively s(...)

Evaluation of the Agronomic Performance of Three Peanut Varieties Arachis hypogea L) and Detection of Diseases.
Soura Hervé, Tchagbe Bernard, Gnancadja Léopold, Koita Kadidia and Savadogo Aly.
Peanut (Arachis hypogea L) is a legume widely produced in West Africa. Peanuts are of agronomic
interest to producers because they are able to fix atmospheric nitrogen, making crop associations
possible, especially with cereals. In Benin, soils are increasingly poor, peanut production in crop
rotation can be an alternative solution. But se(...)

Status report on taro production (Colocasia esculenta L. Schott) and identification of fungal diseases.
Soura Hervé, Bio-Nigan Sikiratou and Gnancadja Léopold
The production of taro (Colocasia esculenta L. Schott) in Benin is struggling to take off, despite its high nutritional value. Taro production faces biotic and abiotic constraints. The acidification of the soil leads to increasingly low yields with a reduction in the size of the tubers. Foliar diseases are major constraints. T(...)
