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(...)

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.(...)

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(...)

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(...)

Impact of land use types on population structure and extent of bark and foliage harvest of Afzelia africana and Pterocarpus erinaceus in Eastern Burkina Faso
Blandine Marie Ivette Nacoulma, Salifou Traoré, Karen Hahn and Adjima Thiombiano
In the West African Sudanian regions, people depend on natural products, especially on highly valued species as source of income, fuel wood, food, medicine, fodder for livestock etc. However, land-use management coupled with unsustainable uses of highly valued trees might jeopardize the long-term viability of some speciesrsquo; populations.

Tree leaves in the diet of free-ranging ruminants in three areas of Burkina Faso
H H Hansen, L Sanou and B M I Nacoulma
A study was undertaken to document the botanical composition of free ranging cattle and small ruminants in three separate areas of Burkina Faso, as the first step towards improved use and management of trees. Faecal samples were taken from cattle at three sites and from small ruminants at one site throughout a year and plant particles in the f(...)

Effet de la fertilisation minérale sur la décomposition d´un mélange de feuilles dans un parc agroforestier à Boni
Hugues R. BAZIE
Agroforestry parklands occupy a key place in farming system of Burkina Faso. However, there is a limited management of the litter from trees of parklands for soil fertility
improvement. Therefore, the present study was carried out with the aim to quantify the litter produced yearly and understand the decomposition rate as well as the release(...)

Effets d’intrants innovants sur les sols et la production de l’aubergine (solanum melongena l.) au Burkina Faso.
Harouna Ouédraogo, Adama Ilboudo, Daouda Guébré, Der Somé, Aminata Ganeme, Koulibi Fidèle Zongo, Aboubacar Coulibaly, Céline Sanou, Edmond Hien
La faible fertilité du sol et les séquences de sécheresse sont des contraintes pour le développement de la production végétale au Burkina Faso.
Une étude a été réalisée pour déterminer les effets du polyter et du turbo-bio sur deux types contrastés de sols et la production de l’aubergine. L’essai a été
installé selon un dispositif en blo(...)
