Local Species

In the area of Lakota (Midwest, Côte d'Ivoire), where the vegetation is a semi-deciduous forest, cacao growing is practiced by people from different origins. Cacao cropping techniques seem to be influenced by some social and cultural habits, according to the people and the agroecological areas. The present study aimed to understand(1) the cacao cropping systems and to identify(2) the reasons underlying the choice of vegetal species combined to cacao trees in these rural communities. To achieve this goal, interviews were realised with cacao farmers of four villages of the area. These interviews concern farmers’ profiles, the former agriculture practices, the variety of the cultivated cacao and the plants combined to cacao trees. The results show that among the 223 interviewed farmers, 72 (32.3% of the farmers) are natives, 42 (18.8% of the farmers) are immigrants and 109 (48.9% of the farmers) are non-native Ivorians. In total, 77 species regularly combined to cacao trees were named by the farmers and they can be divided into local species and exotic species. Plots ordination shows three agroforestry systems according to ethnic group of the locality. Cacao farms with the large proportion of local species are owned by Lakota native people "Dida". The exotic species are dominant in cacao farms that belong to immigrants (Malian, Burkina Faso and Guinean people) and "Malinké" people (a non-native ivorian ethnic group). The Akan people (a non-native ivorian ethnic group) combine in a same proportions exotic and local species in their cacao farms.

Ascending Hierarchical Classification

In Côte d'Ivoire, cashew cultivation faces several health obstacles. Among these problems, bacteriosis causes extensive damage to twigs, leaves and fruits, lowers the quality of crops and causes yield losses. The spread of this disease would be under the determination of the morphological characters of the cashew tree. The objective of this study is to search for agro-morphological determinants that influence the spread of bacteriosis in agroforestry systems in Côte d'Ivoire. To achieve this objective, 30 cashew trees spread across 26 agroforestry cashew orchards in the Korhogo, Sinématiali and Boundiali departments were chosen and geolocated. The study factor is the clone, consisting of 30 cashew genotypes, with 13 modalities. The collected data was subjected to descriptive analysis, correlation test, ACP and ascending hierarchical classification (CAH). The results obtained showed that the size and leaf areas and size of cashew trees are determinants that promote the spread of bacteriosis in these 30 cashew genotypes. Following this result, the ascending hierarchical classification (CAH) made it possible to screen the genotypes into three groups. These results should contribute to the agroecological management of bacteriosis, to enhance and intensify agroforestry cropping systems in Côte d'Ivoire.

Aims: The study aimed to evaluate the nutritional and anti-nutritional factors composition of the Solanum torvum fruit. Place and Duration of Study: Department of Food Sciences and Technology, Biocatalysis and Bioprocessing laboratory of Nangui Abrogoua University (Côte d’Ivoire), between June 2019 and March 2020. Methodology: Proximate composition, mineral element profile and phytochemical composition of fresh and boiled S torvum berries were investigated. The S torvum fruit were harvested fresh. One part was cooked in boiling water for 25 min while the other part did not undergo any treatment. These two samples were dried in an oven at 45°C for 72 hours, ground and analyzed according to official analytical method. Results: The results indicated that the boiling caused the loss of nutrients except moisture, fibers and lipids. It was noted a significant reduction of nutrient and anti-nutrients content of berries after boiling. Boiled berries showed a higher energy value (57.07 Kcal) than fresh ones (53.12 Kcal). Despite the boiling, S torvum berries showed high levels of polyphenols (142.54 mg GAE/100g DW (dry weight)), carotenoids (12.96 mg βCE/100g DW), vitamin C (12.03 mg/100 g FW), fibers (6.88%) and ash (7.23%). Minerals analysis of S torvum berries indicated that it is rich in potassium (2046.77 mg/100 g DW), calcium (340.92 mg/100g DW), phosphorus (238.71 mg/100g DW) and magnesium (234.97 mg/100g DW) with high predicted bioavailability for calcium, magnesium and zinc. S torvum fruit contains also iron (7.97 mg/100g DW) and zinc (8.10 mg/100g DW) which are essential for organism. Conclusion: These data indicated that this Solanum torvum fruit consumed in East of Côte d’Ivoire could constitute a potential good source of nutrients for local population.

The Impact

Aims: To evaluate the impact of different agroforestry systems on the mineral fertility of soils under cocoa trees. Place and duration of study: The experiment was conducted in the field from June to August 2020 in three types of cocoa-based agroforestry systems identified in Toumodi (Côte d'Ivoire) between the northern latitudes 6°19'37 and 6°34'51 and the western longitudes 5°19'58 and 5°20'02. in the forest-savanna transition zone Methodology: Agroforestry systems define a method of setting up plantations associating various trees with cocoa trees. The choice of cocoa plantations was guided by the density of trees associated with cocoa trees defining a typology of agroforests (simple, mixed or complex). Thus, in each agroforestry system considered, three delimited plots of 100 m2 were randomly placed to make a floristic inventory of the species encountered and each time to take elementary soil samples in the first horizons at 0-20 cm and 20 - 40 cm depth to constitute the composite samples for chemical analyses in the laboratory. Results: The study identified and recorded floristically, 17 families (Anacardiaceae, Apocynaceae, Arecaceae, Bombacaceae, Caricaceae, Combretaceae, Euphorbiaceae, Invingiaceae, Lauraceae, Meliaceae, Mimosaceae, Moraceae, Musaceae, Myristicaceae, Rutaceae, Sterculiaceae, Verbenaceae) distributed in 27 local plant species of which 55.55% of the species and a density of 55 trees/hectare in SAGS, 70.37% of the species and a density of 155.33 trees/hectare in MAGS and 81.40% of the species 224.33 trees/hectare in CAGS. These arboricultural species introduced or maintained in the plantations are generally species with shade, food, economic or medicinal interests. In terms of the chemical fertility generated, it appears that the contents of major elements and trace elements, as well as the clay-humus complex of the soils under cocoa trees were globally satisfactory and more important in the superficial horizons at a depth of 0-20 cm than in the underlying horizon of 20-40 cm, whatever the type of agroforestry system considered, but much more so in MAGS than in CAGS and SAGS in decreasing order. The different positive (R=0.80) or negative (R=-0.80) correlations established between the mineral elements in the surface horizons contribute to enrich the soil by synergistic or antagonistic effects in the agroforestry systems of Toumodi, Côte d'Ivoire. Conclusion: The study showed that each forest agroforestry system has distinct characteristics that can be summarized mainly by its floristic diversity and density of associated trees. They are all not only preservers of a certain level of biodiversity and chemical fertility of the soils under cocoa trees, but much more so at 0-20cm than at 20-40cm. However, AGM would be more likely to improve production in a sustainable way by its capacity to establish a nutritional balance in the soil. It can be recommended during the establishment of cocoa plantations in Côte d'Ivoire.
