Cocoa beans sourced from Côte d’Ivoire faces more and more to the high FFA contents. Yet, generation of FFA levels degrades beneficial rheological properties of cocoa butter and chocolate. This study investigated the factors that potentially promote the increase of high FFA contents of Ivorian cocoa beans.
Aims: Free fatty acids (FFA) result from hydrolysis of cocoa butter triacylglycerides due to various abiotic and biotic factors. The resurgence of high FFA contents above 1.75% in cocoa beans depended on Ivorian geographical origin. High FFA contents have become a serious quality problem because they induced serious consequences for some beneficial...
The spatial distributions and associations of plant species in a stand can provide essential information about their dynamics. However, since tree spatial distribution and association depend on factors that operate at different scales, disentangling the effects of environmental heterogeneity and plant–plant interactions requires the choice of a sui...
This study aimed to evaluate the effect of compost from chicken manure, NPK fertilizer and the mixture of both fertilizers on agronomic parameters of four varieties of cassava (Yacé, Bonoua, Six mois and Alleda agba) in Côte d’Ivoire. The field experiment was carried out under a randomized complete block design with three replicates on a ferralitic...
Researches documenting comprehensively the prevalence of seed vivipary in relation to phenology, as well as its impact on production are scant. This article reports the results of investigations carried out during four cropping seasons to quantitatively document seed vivipary in the oleaginous bottle gourd (Lagenaria siceraria). Field experiments w...
The deforestation is a major problem in Côte d’Ivoire. Monogaga protected forest is strongly cleared for agriculture. Thus, the research aims to determine the influence of the farmer’s occupancies on the forest dynamic. The supervised classification by Neural net has been applied with success to Landsat imagery of 1986 and 2017. It has been precede...

The success of HAART has increased the life expectancy of people living with HIV. In order to determine the influence of food consumption on PLWHIV / AIDS, a cohort study was conducted at the Abidjan Military Hospital (HMA) From January 2006 to December 2009, starchy foods, cereals and protein and mineral sources were mostly consumed by patients fr...
Maize is one of the most important cereal used for people and animal alimentation in Côte d’Ivoire, but
its productivity is low. Compost, which is an organic amendment, is known for its efficacy on
agricultural productivity increase, but little is known about its influence on maize productivity in Côte
d'Ivoire. The present study aimed to evaluate...
The increase in agricultural production as well as its nutritional quality at a cost bearable by producers is today a challenge in rural areas. Vermicompost is a low-cost organic amendment known for its effectiveness on agricultural productivity increase but little is diffused about its efficacy on nutritional quality. This study aimed to evaluate...
Description du sujet. L’association culturale est une pratique bénéfique largement utilisée dans les zones tropicales pour la gestion durable de la fertilité des sols, l’amélioration des rendements de l’agriculture traditionnelle et des revenus des petits producteurs. Objectifs. Évaluer l’effet de la culture associée et de la culture pure de la cuc...
Many types of weeds occur in cassava fields causing enormous yield losses due to competition for nutrients, light and space. The purpose of this study was to evaluate the growth and yield of four traditional varieties of cassava (Bonoua Blanc, Tambou, Yassé and Six mois) produced in Côte d'Ivoire and select the highest tolerant variety to weed comp...
Description of the subject. The intercropping system is a beneficial method, which is widely used in tropical areas for sustainable soil fertility management, and has been found to improve both the yields of traditional agriculture and the income of small producers. Objectives. The aim of this study was to compare and evaluate the effect of associa...
An assessment of the competitive indices in intercropping between cassava (Manihot esculenta) and bottle gourd (Lagenaria siceraria) was conducted with the aim of increasing the productivity of these crops. For this purpose, three farmers preferred landraces of cassava (yacé, blêbou and six mois) and three morphotypes of gourd (dark green and round...
The availability of appropriate propagation techniques is a major constraint to the domestication of the forest trees widely used by rural communities; such as Garcinia kola (Heckel). This study tested the ability of root and stem cuttings to regenerate vegetatively when treated with indole- 3-butyric acid (IBA), and set in non-mist poly-propagator...
Among organic amendments, compost is well known for its effectiveness on agricultural productivity increase but little is diffused about vermicompost efficacy. The present study aimed to evaluate the benefits of vermicompost from animal wastes on Lagenaria siceraria productivity and its seeds quality compared to compost. Thus, a field experiment wa...
Lagenaria siceraria is most prized in African society. But its production remains low due to low rate of germination and bad seedling vigor. Use of a good sowing technique could contribute to increase germination rate and seedling vigor. In this context optimization of seeds orientation and sowing depth are essential in cultural practices. This stu...
Lagenaria siceraria Molina has a high productive potential of fruits but the seeds weight remain low. The aim of this study is to regenerate doubled haploids from androgenesis in order to create genotypes with good agronomic characteristics. For this purpose, flower buds of six accessions namely NI185, NI202, NI215, NI276, NI356 and NI271 were pre-...
This study determines the density of the African nightcrawler earthworm (Eudrilus eugeniae) needed to obtain the maximum reduction in heavy metal content during the vermicomposting of cow, sheep, pig and chicken wastes in 90 days. The heavy metal studied are zinc (Zn), copper (Cu), lead (Pb), nickel (Ni), chromium (Cr), cadmium (Cd) and arsenic (As...
Tel.: + 225 08 65 84 67 The number of earthworms necessary for the reliable stabilization of four animal wastes (chicken, cow, sheep and pig) was studied by mineralizing 1 kg of each waste with 5, 10, 15 and 20 individuals of the African nightcrawler earthworm (Eudrilus eugenia Kinberg). Total organic carbon (C), total nitrogen (N), C:N ratio, pH,...
Life history evolution is an important field of modern ecology (Stearns 1992, Begon et al. 2006). A useful approach is to compare the life histories of related organisms to determine how evolution has shaped the relation between different life-history traits. In this context palms are suitable models to study perennial plant demography and life-his...
Two rattans species were studied in Côte d'Ivoire using a stage-classified matrix model to compare their demography and life histories. Respectively 854 and 1009 genets of Eremospatha macrocarpa (pleonanthic) and Laccosperma secundiflorum (hapaxanthic) were censused every 6 mo over 18 mo. The population growth rates of E. macrocarpa (λ = 0.979) and...
