This study was undertaken to measure the impact of fertilizers (nitrogen-potassium) on the growth and the development of plantain banana. Different doses of fertilizers (T2, T3, T4, T5 and T6) were applied to two hybrid varieties (PITA 3 and FHIA 21) and a traditional variety (CORNE 1) on an experimental split plot plan with a planting density of 2500 plants per hectare. Results showed that fertilizers improve parameters of plantain than control (T1). T6 with high potassium content (240 kg•ha −1 N and 987 kg•ha −1 K) improved the growth (35.72 ± 0.95 cm•month −1 ) and the widening (9.56 ± 0.17 cm•month −1 ) of PITA 3, and performed FHIA 21 agronomic parameters by reducing the length of the production cycle and increased the length of fruits. T2 treatment improved FHIA 21 agronomic and yield parameters. Also, the weight of CORNE 1 regimens (9.00 ± 0.67 kg) and fruits (296.59 ± 4.50 g), the length (33.37 ± 0.31 cm) and the circumference (14.73 ± 0.31 cm) increased with T2. T4 induced shorter production cycle of PITA 3 (390.40 ± 0.67 cm•month −1 ), improved PITA3 regimens weight (10.33 ± 0.44 kg) and the number of hands by regimen (6.00 ± 0.00) of FHIA 21. T3 with weak nitrogen content (120 kg•ha −1 N and 658 kg•ha −1 K) improved the characteristics of PITA 3 fruits notably, the weight (176.09 ± 2.96 g) and the circumference (13.87 ± 0.89 cm). T5 (240 kg•ha −1 N and 329 kg•ha −1 K) performed CORNE 1 trees number of sheets (3.85 ± 0.16). CORNE 1 cycle production with T6 treatment was 137.80 days longer than those of T2 treatment (483 ± 3.50 days). In conclusion, with T2 and T6, growth parameters were globally improved in FHIA 21 by the regimen largest and the higher number of fingers, and productivity parameters were improved in CORNE 1 by the heaviest, the longest and the thickest of the fruits.

The African baobab (Adansonia digitata L.) is an indigenous fruit tree in the dry savannah areas of sub-Saharan Africa. It is a species of great dietary and nutritional interest. The pulp of the fruit, in addition to being consumed raw or in cold drinks, is used for several others unknown foods in Côte d’Ivoire. Thus, a household survey was conducted in the localities of Korhogo, Séguéla and Bouna with 135 people per locality in order to identify these foods, and then to determine their modes, forms, frequency of consumption and their processes. The data revealed that consumers collect baobab in pods form (79.23-88.81%) in fields (76.15-86.57%) before using pulp in the preparation of 10 local foods with different technologies. Eight of these foods are meals and two are beverages (Zoom-koom and Séladji). Rural populations for its taste and health benefits consume the pulp of baobab fruit. The process of Bacacrou (Sougé-baca, Badégé-baca, Manou-baca and Sougé ni manou-baca) vary according to the practices of each locality. Among meals, Kagbèlè is a specific food of Korhogo while Séla biscuit is more specific to Séguéla, and Tchobal, Zoom-koom and Bafouratou are specific to Bouna. Sougé-baca and Séladji appears as the most known foods with a percentage of knowledge of 68.39 and 53.35 respectively, and the most consumed dishes precisely at breakfast and at the Muslim jêun break with 3 to 4 times per month as frequency of consumption. For a better promotion of these foods, it is essential to know their biochemical and nutritional composition.

Tamarind (Tamarindus indica L) is a plant belonging to the Fabaceae family and the subfamily Caesalpinioidae that is often found in arid regions. The various parts of this tree are of great interest to rural African populations. The pulp of its fruit is used for the preparation of cold drinks or in the composition of several other foods. However, no study in Côte d'Ivoire has yet focused on these foods, only the juices or nectars of this wild fruit tree have been studied. Thus, a survey was conducted in the localities of Korhogo, Séguéla and Bouna with 135 people per locality in order to identify these foods, and then to determine their modes, forms, frequency of consumption and their processes. The survey revealed that most of consumers are without level of education (78.51%), Ivorian (84.94%) and married (80.99%). The places of supply of tomi are often the field (65.18%-71.64%) than the market (32.84-41.67%) and in its pod form (65.93-73.13%). People use pods and pulp to make 10 tomi-based foods with a meal/drink ratio of 7:3. This fruit is consumed by rural populations for health needs, for its taste and for the color it gives to dishes. The frequency of consumption varies from 0 to 3 times per month and the Sougé-baca appears as the most known and consumed food with a percentage of knowledge of 74.07 and a frequency of consumption of 3 times per month. Sougé-baca is a meal more consumed at breakfast and at the Muslim jêun break. The production diagram of Bacacrou (Sougé-baca, Badégé-baca, Manou-baca and Sougé ni manou-baca) vary according the practices of the three localities.
