Research ArticleOpen accessIn the abstractEffect of Altitude on Species Diversity and Vegetation Structure of Kigelia africana Parklands in CameroonAwé Djongmo Victor, Vroh Bi Tra Aimé, Noiha Noumi Valery et al.In the Faro Subdivision (North, Cameroon), there are populations of Kigelia africana, known by the common name “Dambale", whose variety is largely unknown. The study's goal is to demonstrate how altitude affects species diversity and vegetation structure in Kigelia africana parklands. To gather information for statistical analysis, a Randomized Complete Block Design (RCBD) was employed. A total of 90 quadrats … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 20 Dec 2025 · 3,176 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental Investigation of Thermo-Physical Properties of Soil Using Solarisation TechnologyAhmed Abed Gatea Al-Shammary, Abbas Kouzani, Akif Kaynak et al.Soil Thermo-Physical Properties (TPP) depend on heat transfer in the soil. This paper presents a study on different soil solarisation technologies influenced by soil TPP. This study evaluates three factors: The tillage depth for soil at three levels (15, 25 and 45 cm), the number of plastic film at three levels (single, double and without plastic film) and three cases … …American Journal of Applied Sciences, Vol. 14, Issue 7 · 17 Jul 2017 · 7,957 accessesView PDF Cite
