Weeds control through tree-crop associations in a parkland of Burkina Faso
Josias SANOU, Hugues Roméo BAZIE, Madjelia Cangré Ebou DAO and Jules BAYALA
The effects of microclimate due to tree presence on weeds development were assessed under Baobab (Adansonia digitata) and Néré (Parkia biglobosa) in a parkland in Nobéré (Burkina Faso). In association with these trees, two crops were grown: a shade tolerant crop (Colocasia esculenta, taro) and a shade intolerant cereal (Pennisetum glaucum, Mil(...)

Evaluation de la qualité et de l’acceptabilité de couscous à base de trois formulations de farines composites enrichies au soja (Glycine max) et au moringa (Moringa oleifera)
HAMA-BA Fatoumata, SILGA Rimwaodo Pierre, DIAWARA Bréhima
The enrichment of cereals with other food groups has received considerable attention in recent years.
The objective of this study is to determine the nutritional potential of local food for fortification. The control
formula FT is composed of maize (Wari) and sorghum (Kapelga) flours. The other two formulas are on the
basis of the contro(...)

Strategies trees use to overcome seasonal water limitation in an agroforestry system in semiarid West Africa
A. Bargués Tobella, N.J. Hasselquist, H.R. Bazié, G. Nyberg, H. Laudon, J. Bayala, U. Ilstedt
Agroforestry parklands, in which annual crops are grown under scattered mature trees, constitute the most prevalent farming system in semiarid West Africa, covering vast areas of land. The most dominant tree species in these systems is Vitellaria paradoxa, an indigenous tree to West Africa. Despite the importance of this tree in the region, no(...)

Aperçu de la culture du voandzou (Vigna subterranea (L.) Verdcourt) au Burkina Faso: enjeux et perspectives d’amélioration de sa productivité.
Adjima OUOBA, Mahama OUEDRAOGO, Mahamadou SAWADOGO et Sabine NADEMBEGA
Le voandzou constitue avec le niébé, les deux principales légumineuses alimentaires pour de
nombreuses populations rurales et la frange pauvre des citadins au Burkina Faso. Cependant, des informations
émanant de l’environnement de production de cette culture selon la perception des producteurs sont quasi
inexistantes. Cette étude vise à s’i(...)

Diversity and seasonal distribution of parasites of Oreochromis niloticus in semi-arid reservoirs (West Africa, Burkina Faso)
Yamba Sinaré, Magloire Boungou, Adama Ouéda, Awa Gnémé and Gustave B. Kabré
This study aimed to investigate the diversity, abundance, intensity, and seasonal distribution of parasites of Oreochromis niloticus. A total of 254 specimens of O. niloticus was sampled in Loumbila and Ziga reservoirs in both rainy and dry season and examined for parasites. The total prevalence was 55.90% and the highest seasonal prevalence,(...)

Effets de la date de semis et du régime hydrique sur la réponse agromorphologique de deux variétés de niébé (KN1 ET KVX 61-1) au Burkina Faso
Adama Pascal KIHINDO , Romeo Hugues BAZIE, Razacswendé Fanta OUEDRAOGO, Pépin Patrice SOME, Gérard ZOMBRE, and Koffi TOZO
Cowpea (Vigna unguiculata L.Walp.) is a basic food product which is cultivated in the savannas of west Africa. Its cultivation is confronted to biotic and abiotic constraints. The abiotic constraints are primarily of climatic types (recorded rainfall, temperature). The bad spatiotemporal distribution of recorded rainfall as well as the high te(...)

Caught in a human disturbance trap: Responses of tropical savanna trees to increasing land-use pressure
Oumarou Ouédraogo, Loyapin Bondé, Joseph I. Boussim, Anja Linstädter
Increasing land-use pressure threatens the persistence of tree populations in West Africa’s savannas. We do not fully understand yet why tree species respond differently to human disturbances, hampering the design of appropriate management strategies. To identify typical response pathways, we compared tree populations in three land-use types w(...)

APPLICATION DES MÉTHODES STATISTIQUES À L’ÉTUDE HYDROCHIMIQUE DES EAUX D’UN HYDROSYSTÈME TROPICAL : CAS DU BASSIN VERSANT DE LA RIVIÈRE ZIO (TOGO)
Tampo L., Gnazou M., Akpataku V., Bawa L., Djaneye-Boundjou G, Nuto Y, Oueda A. et Guenda W.
Zio River is the only perennial river of Lake Togo basin. It passes through many urban areas including capital Lomé which it receives discharges of all kinds and subjected to several human pressures. This study aims to characterize the physicochemical quality of water from the source to the river mouth, identify pollution sources and highlight(...)

Separating autotrophic respiration due to roots from soil heterotrophic respiration in an agroforestry parkland system in Saponé, Burkina Faso
H.R BAZIÉ, J. SANOU, Z. GNANKAMBARY, P.P. SOMÉ, G. ZOMBRÉ and J. BAYALA
Soil respiration is the largest component of ecosystem respiration but little is known about it and its components in parkland systems. We therefore conducted an experiment to estimate the amount of CO 2 respired and to partition it into soil, tree root and crop root contributions in parkland systems in Burkina Faso. Three factors effects were(...)

Interactions arbres-cultures et rôles des parcs agroforestiers à Vitellaria paradoxa (CF Gaertn) sur les paramètres du bilan hydrique au Burkina Faso
H. BAZIE
Agroforestry parklands are the most widespread production systems across Burkina Faso and the Sahel, with key species being Vitellaria paradoxa and Parkia biglobosa. The overall aim of the research was to contribute to a better understanding of the interactions in the tree-crop associations, and the impact of Vitellaria paradoxa parklands on t(...)

Impact des gradients topographique et anthropique sur la diversité des formations ligneuses soudaniennes
Loyapin BONDÉ, Oumarou OUÉDRAOGO, François KAGAMBÈGA, Joseph I. BOUSSIM.
Le paysage soudanien est en pleine mutation avec une conversion progressive des formations soudaniennes en formations sahéliennes. Dans cette étude, menée sur les formations ligneuses soudaniennes, l’objectif était d’évaluer, d’une part, les effets isolés du mode d’utilisation des terres et de la position topographique et, d’autre part, celui(...)

RELATIONSHIPS BETWEEN SOIL MICROBIAL BIOMASS, AGGREGATE STABILITY AND AGGREGATE ASSOCIATED-C: A MECHANISTIC APPROACH
Patrizia Guidi, Gloria Falsone, Mare Boussa Tockville, Gilmo Vianello
For the identification of C pools involved in soil aggregation, a physically-based aggregate fractionation was proposed, and additional pretreatments were used in the measurement of the 1-2 mm aggregate stability in order to elucidate the relevance of the role of soil microorganisms with respect to the different aggregate breakdown mechanisms.(...)

RELATING LOSS OF SOIL FERTILITY TO WATER AGGREGATE STABILITY AND NUTRIENT AVAILABILITY IN MOUNTAIN AGRICULTURAL CALCARIC SOILS
Patrizia Guidi, Gloria Falsone, Boussa Tockville Mare, Andrea Simoni, Paola Gioacchini, Gilmo Vianello
We investigated the topsoil from some mountain Regosols for their nutrient status and loss of fertility due to aggregate breakdown, establishing also the relationship between the nutrient losses, the soil characteristics and the aggregates stability. The aggregate stability varied from 57 to 80%. The nutrient losses differed among elements and(...)
