In Burkina Faso, okra is one of the most important vegetable crops. Low soil fertility is one of the major constraints to okra production. The objective of this study was to evaluate the effect of mixed bovine and ovine stabling on soil properties and on growth and yield of okra in Sudano-Sahelian zone. The study was conducted during the 2023-2024 agricultural season. The experiment design used is a Randomized Complete Block Design with two treatments (with and without stabling) and four replications. The data collected are plant height, collar diameter, number of leaves, number of flowers, soil temperature and soil pH. Results of the study showed that the stabling treatment (PR) recorded the highest pH (6.27), the highest fruit weight (137.62 g plant-1) and the best fruit yield (2.75 t ha⁻¹), i.e. a yield gain of 17.62% compared to the control (TA). These results highlight that mixed...

The study compared 37 new soybean genotypes and three local controls in two agroecological zones in Burkina Faso using an alpha-lattice design. Analysis of variance (ANOVA), additive main effects and multiplicative interaction (AMMI) analysis, and genotype plus genotype-environment interaction (GGE) biplot analysis revealed highly significant effects of genotype, environment, and genotype-environment interaction, as well as high stability and high yield for five genotypes (TGX2017-6E, TGX1987-14F, TGX1987-10F, TGX2018-5E, and TGX2007-3F). Three lines showed specific adaptation to the wetter southern Sudanian site, and no severe symptoms of rust or mosaic virus were re ported. Variety registration could be considered for the most stable genotypes, with Fada N’Gourma as the main trial site.

Agricultural systems in Sub-Saharan Africa are often characterized by low agrodiversity and high vulnerability to climate change, both of which can compromise food security and livelihoods. Many Neglected and Underutilized Plant Species (NUS) are known for their nutritional value and climate resilience, presenting a potential solution to conserve agrodiversity and ensure local livelihoods and food security. However, NUS are commonly used as an umbrella term, obscuring potential differentiation between NUS systems in terms of their characteristics and socioeconomic performance. Here we characterize NUS production systems in three regions of Burkina Faso, a country experiencing high food insecurity, poverty and arid and semi-arid climatic conditions, where many local communities rely on NUS for their food and livelihoods. We conducted 432 in-person surveys with households cultivating NUS o...

The centre of origin of Bambara groundnut (BGN; Vigna subterranea L.) is Western Sub-Saharan Africa. Due to its high nutritional value and tolerance to biotic and abiotic stresses, this neglected and underutilised species has recently gained significant attention. However, BGN production faces several challenges, including a lack of quality varieties. This study describes a selected core collection based on phenotypic traits, investigates relevant selection criteria and identifies a set of landraces according to participants’ preferences. A core collection of landraces was generated, described, and then subjected to participatory varietal selection. Through individual semi-structured interviews, key selection criteria were identified. Focus group discussions were organised to explore group criteria and to support and validate information from personal interviews. The varietal selection...

Malnutrition constitutes a public health problem throughout the world and particularly in developing countries. The objective of the study is to assess the impact of an elementary integrator composed of Spiruline (Spirulina platensis) and Misola (millet, soja, peanut) produced at the Centre Medical St Camille (CMSC) of Ouagadougou, Burkina Faso, on the nutritional status of undernourished children. 550 undernourished children of less than 5 years old were enrolled in this study, 455 showed severe marasma, 57 marasma of medium severity and 38 kwashiorkor plus marasma. We divided the children randomly into four groups: 170 were given Misola (731±7 kcal/day), 170 were given Spiruline plus traditional meals (748±6 kcal/day), 170 were given Spiruline plus Misola (767±5 kcal/day). Forty children received only traditional meals (722±8 kcal/day) and functioned as the control …

The cowpea aphid (Aphis craccivora Koch.) is a significant pest of cowpea crops, causing considerable damage to seed production. To identify cowpea genotypes resistant to aphids and demonstrating strong agronomic performance, fourth generation genotypes (M4) derived from the cowpea variety Tiligré, which was irradiated with 150 Gy of gamma radiation, were screened with aphids using a free choice method under screen house conditions over three consecutive years. The genetic material included the parent Tiligré, two susceptible checks (KN-1 and KVx61-1), and two resistant checks (IT97K-556-6 and KVx295-2-124-99). Data on the number of adult aphids per plant, survival percentage, flowering date, pod and seed weight per plant, and the weight of 100 seeds were recorded. The investigation revealed that TiligréM157, TiligréM27, TiligréM42, and TiligréM56 reduced between 19 and 33% aphids’ mult...

According to the World Health Organization (WHO), anaemia is defined as a decrease in haemoglobin concentration below the reference values relating to age, sex and physiological condition. It is a widespread public health problem with major consequences on health, as well as on economic and social development. The objective of this study was to characterize anaemia in children aged 0 to 5 years in the Haematology Laboratory of the Yalgado OUEDRAOGO University Hospital in Ouagadougou. It was a descriptive cross-sectional study that took place from January 2020 to December 2020 and which collected 1,179 children. The average age was 23±22 months. The average haemoglobin level was 104.6 ± 33.2 g/L. The prevalence of anaemia was 61%. Anemia affected 59% of boys, i.e. a sex ratio of 1.42. The age group 0-5 months was the most affected by anaemia, with a frequency of 21%. The monthly...

Cet article s’intéresse à l’adaptation psychologique des élèves déplacés internes dans un contexte de crise sécuritaire au Burkina Faso. Il pose le problème de d’adaptation psychologique liée à l’environnement scolaire, à la zone d’accueil et à la personnalité des élèves déplacés handicapés. L’objectif de cette réflexion est d’analyser l’impact du degré d’adaptation des élèves déplacés internes handicapés sur leurs performances. L’étude s’appuie sur des données qualitatives recueillies à travers un guide d’entretien, une grille d’observation et l’échelle Liste des Comportements pour Enfants. Ces données ont fait l’objet d’une analyse de contenu de type thématique. De cette recherche il ressort que (i) les élèves déplacés internes handicapés font des troubles tels que le stress posttraumatique, la dépression ou des comportements de retrait. Ces troubles sont à même d’affecter leur...

Au Burkina Faso, les divorces, les foyers monoparentaux et les familles recomposées engendrent souvent l’absence du père biologique de la famille de résidence de l’enfant, laquelle absence peut être problématique pour le développement affectif de l’enfant. Cet article a pour objectif d’explorer le lien entre l'absence du père, le développement affectif et les performances scolaires des enfants Burkinabè. La méthode quantitative a été utilisée pour générer des données objectives et les comparer. À travers un échantillonnage non probabiliste, 60 enfants (filles et garçons), âgés de 5 à 7 ans, répartis entre ceux vivant avec leurs deux parents biologiques et ceux résidant dans des familles monoparentales ou recomposées, a été choisi et interrogé. L’instrument de mesure du développement de la petite enfance (IMDPE) a été administré à travers l’application Kobocollect. Il remplit une fonction...

West Africa constitutes a hotspot region for both land use change and climate change. Land use change, and highclimate variability in this region negatively affect tree growth dynamics, ecosystem functioning and services. In the presentstudy, we assessed the impacts of climate variability on tree growth of Detarium microcarpum Guill. & Perr. and Tamarindusindica L., two Fabaceae woody species with high socio-economic significance in West Africa. In total, we collected 18 stemdiscs from dead trees of the two species in the South-Sudanian phytogeographic zone in Burkina Faso. The studied speciesshowed well-defined growth ring-boundaries demarcated by marginal parenchyma bands. Cross-dating was successful withindisc and within species, and enabled the construction of statistically robust tree-ring index chronologies. The chronologiesspanned 45 years (1974 − 2019) and 30 years (1990 − 2019)...
