The present study aims to determine the optimal dose of ox dung and the sowing density that optimize the yield of seed cotton in the region of BERE in the North-West of Côte d'Ivoire. Six fertilizer doses (T0, T1, T2, T3, T4 and T5) were tested. Among these six doses, T1, T2, T3 and T4 are composed of a mixture of ox dung and NPK mineral fertilizer, T0 is the mineral NPK fertilizer and T5 is composed only of cattle dung. These doses were tested on cotton plants through 4 seeding densities : low density (LowD : 50 cm x 80 cm with 2 plant.pocket-1, either 50000 Plant.ha-1), medium density 1 (Me D1: 40 cm x 80 cm with 2 plant.pocket-1, either 62500 Plant.ha-1), medium density 2 (Me D2 : 20 cm x 80 cm with 1 plant.pocket-1, either 62500 Plant.ha-1) and high density (Hi D : 30 cm x 80 cm with 2 plant.pocket-1, with 83500 Plant.ha-1). Observations focused on six agronomic parameters. All the organo-mineral treatments were more productive than the simple NPK and beef dung treatment. The T2 treatment (2000 kg.ha-1 of cow dung + 100 kg.ha-1 of NPK) made it possible to observe the highest values of the number of capsules per plant (14.37 capsules), of the cottonseed mass per plant (57.02 g) and seed cotton yield (3636.23 kg.ha-1). In terms of sowing density, cotton plants sown under high density (Hi D : 30cm x 80cm, or 83,500 Plant.ha-1) gave a higher seed cotton yield (3950.68 kg.ha-1). The medium seed cotton yield of cotton plants reached its optimum (4434.77 kg.ha-1) when they were sown at high density (83500 Plant.ha-1) and treated with T2 (2000 kg.ha-1 of cattle dung + 100 kg.ha-1 of NPK).
The aim of this study is to establish a link between the performance at speed race and the somatotype within young students from Côte d'Ivoire who are candidates for the recruitment test organized by the National Institute of Youth and Sports. The study was performed on 669 girls at 21.80+2.26 year old and 1859 boys at 22.11+2.26 years. Anthropometrical measures were made out in order to estimate somatotype. For the speed, the subjects underwent a 80m speed race test for girls and a 100m speed race for boys. After a descriptive analysis of the somatotype components and the performance of girls and boys, we made a distribution of the gaps in performance (estimated performance -real performance) estimated by the regression and the real performance in order to check normality. To examine the relationship between somatotype, cormic index and the speed race, an equation of multiple regressions was performed. The distribution of the gaps in performance (estimated performance -real performance) estimated by the regression and real performance is normally distributed both in girls and boys. The results also indicate that a multiple and statistically significant link (p<0.05) exists between the performance and three (3) variables:European Scientific Journal August 2016 edition vol.12, No.23 ISSN: 1857 -7881 (Print) e -ISSN 1857-7431 379 endormorphy, ectomorphy and cormic index with boys and two (2) components of somatotype: endomorphy, mesomorphy with girls. The present study has allowed establishing a relationship between the performance at speed race and some of the components of the somatotype. The performance at 100m for boys and 80m for girls is well the result of a specific morphotype (endomorph) limiting the realization of good performances by these sprinters.

Cette étude a porté sur 669 filles âgées de 21,80±2,26 ans et 1859 garçons âgés de 22,11±2,26 ans. Des mesures anthropométriques ont été effectuées pour déterminer le somatotype. Pour la vitesse, les sujets ont été soumis à un test de course de vitesse sur 80 mètres pour les filles et sur 100 mètres pour les garçons. Après une analyse descriptive des composants du somatotype et de la performance chez les filles et chez les garçons, nous avons fait une distribution des écarts de performance (perf estimée -perf réelle) estimée par la régression et la performance réelle pour vérifier la normalité. Pour examiner la relation entre le somatotype et la course de vitesse, une équation de régression multiple a été établie. La distribution des écarts de performance (perf estimée -perf réelle) estimée par la régression et la performance réelle est gaussienne aussi bien chez les filles que chez les garçons. Les résultats indiquent également qu'il existe une liaison multiple et statistiquement significative ...
Objective: To evaluate the effects of 8-week specific Fitness training program on the physical, mental and immunological health of women infected by the virus of the human immunodeficiency and on antiretroviral treatment (ARVT). Methods: a program of sixteen sessions of specific Fitness training displayed over 2 months with two sessions of one hour a week was realized in 48 physically inactive women from 25 to 52 years old, living with the HIV and under antiretroviral treatment. The physical health of the women was evaluated before and after two months of training through body mass index, muscular strength, recovery from exhaustive exercise capacity, flexibility, general balance, immunological state, self-confidence, and self-esteem. The effects of specific fitness training on these parameters were examined through statistical tests of comparison (student t test, paired sample and frequencies). Results: the results of sixteen sessions of training show a significant improvement (p˂0,05) on the general health through the corpulence, the European Scientific Journal August 2016 edition vol.12, No.23 ISSN: 1857 -7881 (Print) e -ISSN 1857-7431 222 muscular strength, the recuperative capacity, the flexibility, the general balance, the immunological state, the self-confidence, and the self-respect. Conclusion: the implication in the practice of physical activities contributes to improve the health, the quality of life of the PVVIH and the image that they have of themselves, so favoring an acceptance of their own situation and reducing the exclusion, the discrimination and the stigmatization of which they feel victims.
Several studies conducted in recent years in Côte d'Ivoire reveal that agriculture is increasingly affected by the adverse effects of climate variability. The present study aims at evaluating the effect of the zone and the year of cultivation on the productivity of maize in the Central and North-Central zones of Cote d'Ivoire. It was carried out for two years (2020 and 2021). The experimental design used was a completely randomized block design with three replications. Observations were made on 12 agronomic parameters (plant size, internode size, collar diameter, number of leaves, number of internodes, cob insertion level, cob length, cob diameter, total kernels, cob dry weight, kernel dry weight, yield). The results showed that all agronomic traits of maize were significantly influenced by locality, except for the number of leaves. The highest values of the traits were observed in the locality of Bouaké. However, the year of cultivation did not influence the agronomic parameters of maize. This study will help to avoid yield decreases due to rainfall disturbances as a consequence of climate change.
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.
The decline in yam productivity due to the lack of arable land and impoverished soils forces farmers to use fertiliser. The fertilisers used are mineral, organic or organo-mineral. A study of these fertilisers has been carried out to propose to the farmers a dose or combination that can improve their yield. Thirteen (13) fertilisers obtained from the combination of mineral fertiliser (NPK 15-15-15) and composted cow or poultry manure were tested on the yam variety Krengle in a 3 replicate randomized complete block design. The experiment was conducted over two (2) campaigns at Bouake in Central of Côte d’Ivoire. The results show that high dose mineral fertilisation (NPK 15-15-15, 300 kg/ha) negatively influenced the growth and yield parameters of the yam variety Krengle. High doses of organic fertilisers (Cow manure (CM) 20 t/ha and poultry manure (PM) 20 t/ha) have a positive effect on vegetative growth. While the medium-high doses of organic fertiliser (CM 15 t/ha and PM 15 t/ha) gave better tuber yield (13.5 t/ha) and allowed an increase in tuber yield from 17 to 18%. Organo-mineral fertilisation combining a small dose of organic fertiliser (5 t/ha) with a medium dose of mineral fertiliser (200 kg/ha) gave also fairly good yield (13.3 and 14.42 t/ha) with an increase of 15 to 25%. Thus, 200 kg/ha of NPK 15-15-15 associated with 5 t/ha of poultry or cow manure can be recommended for the cultivation of the yam variety Krengle at Bouake.
