In Côte d’Ivoire, the sweet potato is little cultivated but stays however a culture of pension and a food mattering in certain regions. This study was conducted to assess the effect of the application of mineral (NPK 15-15-15, NPK 12-22-22) and organic (poultry manure) fertilizers on yield components of sweet potato (Ipomoea batatas (L) Lam). The experiment was conducted over two years (2016 to 2017) in experimental station of National Center of Agronomic Research (CNRA) of Bouaké in the centre of Côte d'Ivoire. The experiment was conducted following a split plot with 2 factors (variety and fertilizers) and 3 replicates. The main factor was variety with 2 levels (variety Irene and variety TIB-440060) and the subplot was fertilizers application consisted 13 levels (200, 300, 400, 500 kg ha-1 of NPK fertilizers combined 5, 10, 15 t ha-1 of organic fertilizer). Thirteen treatments based on poultry manure (T6, T7), chemical fertilizer NPK 15 15 15 (T1, T3, T4, T5) and NPK 12 22 22 (T8, T10, T11, T12) and their combination (T2 and T9) were tested. The experimental results revealed that that the effects of chemical fertilizer treatments, manure and their combination with mineral fertilizers did not influence the measured parameters. The results also showed that fertilizers improved all the agronomic parameters of sweet potato compared to the control treatment during two years of experiment. However, the Irene variety with a mean weight of 180 g tuberous roots was significantly different from the TIB variety with a mean weight of 138.73 g. In the conditions of our study and over the two-year period, producers of sweet potatoes would benefit from using organic fertilizers with the Irene variety.

La production de la patate douce, Ipomoea batatas (L.) Lam., reste confrontée à de nombreuses contraintes agronomiques. Pour mieux faire face à ces contraintes, une étude a été réalisée dans le but de déterminer les caractères agronomiques de sept (7) variétés de patate douce cultivée au centre de la Côte d’Ivoire (Bouaké) afin de sélectionner les variétés les plus adaptées. Dans cette étude, le taux de survie, la biomasse aérienne, la résistance aux insectes et ravageurs ont été évalués. Les résultats obtenus ont montré que les variétés Covington, CIP et Irène ont enregistré les meilleurs taux de survie. Au niveau de la biomasse aérienne la variété Irène s’est distinguée des autres variétés. La variété Fadanga a été moins sensibles pour l’ensemble des nuisibles influençant la patate douce.

Sweet potato is an important food security crop in Sub-Saharan Africa. In Côte d’Ivoire, the roots are widely consumed as supplementary staple food or secondary food. The present study is conducted to highlight the nutritive composition, antinutrients and β-carotene contents of local sweet potatoes consumed in Côte d’Ivoire. The nutritive properties and antinutritive factors of these sweet potatoes were investigated using standard methods. Results confirmed the energetic value (363±1.63-374.08±0.56 kcal/100 g DM) of whole sweet potato flour, mainly due to its high carbohydrate content (86.75±0.40%-90.87±0.12%). Whole flour recorded low contents of moisture (4.50±0.10-6.30±0.15%), lipids (0.63±0.08-1.94±0.95%) and proteins (0.94±0.36-1.91±0.15%). The antinutritive factors ranged from 55.84±0.13 to 70.52±0.07 mg/100 g DM and 52.30±5.81-92.44±11.10 mg/100 g DM for oxalates and phytates, respectively. The mineral contents were: magnesium (49.37±1.09-540.87±0.82 mg/100 g DM), calcium (50.28±1.14-110.53±0.79 mg/100 g DM), phosphorus (25.12±1.04-42.75±0.82 mg/100 g DM), potassium (906.25±0.33-1625±0.61 mg/100 g DM), and iron (5.62±0.84-26.89±0.76 mg/100 g DM). The sweet potato flours highlighted polyphenols and antioxidant activity varying from 92.80±98.20±1.72 to 224.46±0.86 mg GAE /100 g DM, and 31.03±0.52-58.63±0.60%, respectively. While β-carotene levels of flours varied from 0.19±0.08 to 22.71±0.67 µg/g DM for white to orange cultivars. At the whole, the orange fleshed sweet potato cultivars recorded an appreciable amount of minerals (magnesium, iron and calcium), polyphenols and greater antioxidant activity. This indicates that these sweet potato cultivars may present a potential asset for their using as natural antioxidants to prevent chronic diseases and undernourishment caused mineral deficiency. The results also showed that the orange-fleshed varieties may contribute for vitamin A deficiencies alleviation in children of rural areas of Côte d’Ivoire.

Aims: This study evaluated the sensory properties and consumer acceptability of orange-fleshed sweet potato and local sweet potato among households of Central and Northern Côte d’Ivoire. Study Design: Selection of sweet potato cultivars, determination of nutritional properties, cooking process, and evaluation of hedonic testing and consumer acceptability. Place and Duration of Study: Bouake and Korhogo district in Central and Northern Côte d’Ivoire, for three years 2018, 2019, and 2020 (July to November). Methodology: Sensory evaluation and acceptability were performed using a nine-point hedonic scale. The relationships between the sensory attributes and the sweet potato cultivars were analyzed using a Principal Component Analysis plot. Biochemical standard methods were used to determine the dry matter, sugar, total carotenoid contents, and mineral composition of sweet potato cultivars tested by the sensory panel. Results: All twelve sweet potato cultivars were accepted based on sensory attributes with the different traits of preference. In Bouake district, white (Sanfo Figui 1 and Sanfo Figui 2) and yellow cultivars (Fatoni 2) were most preferred for their texture and yam-like taste, while in Korhogo locality, OFSP (Covington TIB-440060, CIP-199062-1 and Irene) and yellow cultivar (Gotchan) were most accepted because of their attractive appearance and their sweet taste. The OFSP cultivars recorded low dry matter and high sugar content compared to white and yellow varieties. Also, OFSP showed the highest content of carotenoid (181.70 to 351.47 µg/g dw), while local variety recorded low content. All the sweet potato cultivars tested contain mineral components. Conclusion: This study shows that the local and OFSP varieties were successfully accepted by the consumer with the different quality traits. The main quality traits that determine consumer preference are appearance, texture, and taste (none or sweet taste). Understanding consumer quality traits can increase the effectiveness of breeding programmes, increase yield and adoption of new varieties.

Introduction: In Côte d'Ivoire, there is an imbalance between the dietary intake and the nutritional requirements of school-aged children. The objective of this study was to analyze the effect of food diversification, namely sweet potato, soya and cowpea, on vitamin A, D and E profiles among school-aged children in Côte d'Ivoire. Methodology: This study was conducted over eight months (from October 2017 to May 2018). It included 240 school-aged children (6 - 12 years old) who were divided into four groups of 60 pupils. These children consumed food at school canteens in 12 localities of the Nawa region. Four types of meals were proposed: rice with fish (Group 1 control), sweet potato porridge accompanied by green soybean (Group 2), sweet potato porridge accompanied by white cowpea (Group 3), and sweet potato porridge accompanied by cowpea with soya balls (Group 4). Three blood samples were collected: Phase 0 (prior to the consumption of the meals), Phase 1 (sampling taken three months later) and Phase 2 (sampling taken six months later). Blood assay for vitamins A, D and E was performed using high performance liquid chromatography (HPLC). Results: Before the children consumed food at the canteen (phase 0), a sufficient amount of vitamins A, D and E was observed, except for group 4 where a deficiency of vitamin D (<30 ng/mL) was noted. The levels of vitamins A and D decreased in groups 1, 2 and 3 from phase 0 to phase 2. However, they increased in children of group 4 from 0.5 to 0.8 mg/L and from 22 to 28 ng/mL respectively. The vitamin E level increased in all groups from phase 0 to phase 2. The improvement in vitamin E status was more remarkable in the children of group 2 and group 4 with levels varying from 8.5 to 11.8 mg/L and 8.3 to 10.6 mg/L respectively. Conclusion: Improvements in vitamin A, D, and E status were more pronounced in children who ate sweet potato, soybean, and cowpea meal compared to their mean concentration at the beginning of the study. The sweet potato, soybean, and cowpea-based meal could be chosen as a means of food diversification in school canteens in order to improve the vitamin status of school-aged children.
