Agromorphological characteristics of Irvingia gabonensis (Aubry-Lecomte ex O'Rorke) Baill. (Wild mango) and its effect on Theobroma cacao L. in traditional agroforestry systems
The study was conducted in the localities of Buyo, Duekoué, and Gueyo in western Côte d'Ivoire, within agroforestry systems that combine cocoa trees with Irvingia gabonensis. The aim was to enhance cocoa production in Côte d'Ivoire by associating it with I. gabonensis to achieve sustainable production. To achieve this goal, plots with radii of 10 and 20 m around I. gabonensis trees were...

Managing brown leaf spot disease in rice: Insights into Bipolaris oryzae pathogenesis and management strategies
Bipolaris oryzae is a severe Ascomycete pathogen responsible for brown leaf spot in rice, resulting in significant yield losses in both quantity and quality. This disease is prevalent worldwide, affecting most rice-growing regions and holding historical significance for many rice-producing countries. The pathogen can infect rice at any growth stage, manifesting symptoms on various plant parts. Initial symptoms appear as...

Field evaluation of irrigated rice double haploid lines to identify high-yield accessions adapted to weed control
Weed herbicide resistance threatens the sustainability of the world’s rice. This study aims to select high-yielding and competitive rice genotypes against weeds. It was conducted at the PNSAV-PV research station in Kougouleu. The experimental design was a split plot, with the main factor being the weed regime and the secondary factor comprising fifteen genotypes during two consecutive rainfall seasons. Parameters...

Investigating the potential of a systems approach for false codling moth, Thaumatotibia leucotreta (Lepidoptera: Tortricidae) and fruit flies (Diptera: Tephritidae) on ‘Hass’ Avocado
The false codling moth, Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae), fruit fly species of the genus Ceratitis (Diptera: Tephritidae), and the invasive oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), are pests associated with avocado production in South Africa. Phytosanitary measures are necessary to prevent the introduction of these pests into countries where they are not...

Effect of organic and inorganic fertilization on the growth and yield of two Amaranthus accessions
The production of Indigenous leafy vegetables such as Amaranthus could address malnutrition and food insecurity experienced globally by providing the necessary nutrients needed in a balanced diet. However, escalating prices of chemical fertilizers make them unaffordable to small-holder farmers and this aggravates more threat to food security. This is because an adequate nutrient supply through fertilization is essential...

Bioassay test of pyrethrum extract for the management of maize and bean weevils treated with different dosages
Insect infestation has a direct impact on agricultural food production and stored products, resulting in 20 to 30% product loss, and in severe cases, total loss. A laboratory study was conducted to determine the response of maize and bean weevils treated with different dosages and exposure times pyrethrum extract. The pyrethrum extracts were prepared at six dosage levels (0.5, 1.0, 1.5, 2.0, 2.5, and 3.0% w/v) and mixed...
