Effets Du Labour Mécanisé Successif Sur Le Statut Nutritif Du Sol Et Le Rendement Du Riz Pluvial Dans La Commune d’Abomey Calavi (Sud Bénin)

The effects of mechanized plowing with power tiller and rotavator and that of the succession of production campaigns on the nutritive status of soil and the rice yield in pluvial system were studied in the low land of Dokomey in South of Benin. The methodological approach is based on field trials conducted during three successive production campaigns from 2014 to 2016 according to a split plot design with one factor (plowing).. Sampling and analysis of the physical and chemical soils’ parameters were done at the beginning and end of each campaign and also the weighing of harvested paddy. Results showed that the fertility of the plots which received mechanized plowing and that of their yields increased noticeably during each campaign and along all the campaigns than those which received manual plowing. For example, from campaign 1 to 3, the yields under mechanized plowing increased respectively of 35%, 37% and 39% more than those obtained under manual plowing. The same report was obtained for soils parameters where the contents of organic matters (OM), nitrogen (N), ratio C/N, cationic exchange capacity, assimilable phosphorus (Pass) and clay increased respectively of 31,63% ; 11,77% ; 13,39% ; 10,28% ; 6,03% et 3,74%.Moreover, the correlations study between yield and nutritive status of soil showed likewise a high dependence between those parameters and the obtained yields. This dependence was highly significant at the level of 0.1% for th mechanized plowin

Evaluation de límpact de la reeducation sur látaxi cerebelleuse par les indices de barthel et de tinnetti a cotonou

L’ataxie cérébelleuse est un trouble moteur complexe qui influence la planification et l’exécution des mouvements et qui en réduit la précision et la coordination.Objectif Evaluer l’impact de la rééducation sur l’ataxie cérébelleuse au CNHU de Cotonou.Méthode Il s’agit d’une étude rétrospective, descriptive et analytique portant sur 46 cas d’ataxie cérébelleuse ayant bénéficié d’un programme de rééducation.Résultats L’ancienneté de la maladie a varié de 0 à 6 mois dans 63% des cas et a été supérieure à 36 mois dans 15,2% des cas. L’adiadococinésie, la dysmétrie, la maladresse à l’écriture, l’élargissement du polygone de sustentation, la marche pseudo ébrieuse et la dysarthrie ont été observés chez 93 à 100% des patients. La rééducation a permis d’obtenir une autonomie complète dans les activités de la vie journalière (AVJ) chez 43,5% des patients et une autonomie relative chez 50,0% selon l’indice de Barthel. A l’évaluation de l’équilibre et de la marche selon Tinetti, 89,1% des patients ont amélioré leur score dont 60,9% (19- 25) et 29,2% (26-28). Les patients qui ont commencé précocement la rééducation, sont ceux qui ont obtenu une autonomie complète dans les activités de la vie journalière. Les résultats des patients célibataires ont été meilleurs à ceux des mariés et des enfants avec une différence statistiquement significative (p= 0,045).Conclusion La rééducation a donc eu un impact global bénéfique sur l’ataxie cérébelleuse et ce d’autant plus que les patients ont précocement commencé leur rééducation ou qu’ils étaient célibataires

Response of Jute Mallow (Corchorus olitorius L.) to organic manure and inorganic fertilizer on a ferruginous soil in North-eastern Benin

Objective: The study aimed to evaluate the effects of three types of fertilizers (Municipal solids waste compost, cow dung and chemical fertilizer) on growth characters and leaf yield of Corchorus olitorius under irrigated conditionsMethodology and results: A field experiment was conducted in Parakou in the dry season using a randomized complete block design with three factors and twelve treatments: 1) Municipal solids waste Compost (MSWC) at 0, 10, 20 and 30 t.ha-1; 2) Cow dung at 0, 10, 20 and 30 t.ha-1; Urea fertilizer (46% N) at 0, 50, 100 and 200 kg.ha-1. The plant height and stem diameter were significantly higher with Compost (20 t/ha) and lowest was recorded in control at all growth stages. The application of compost, cow dung and chemical fertilizer significantly increased the total number of branches at all growth stages. The highest number was recorded in MSWC 20 t.ha-1 as compared to the other treatments. The highest marketable leaves yield was obtained with MSWC at 20 t.ha-1 (8.1 t.ha-1) followed by MSWC at 30 t.ha-1 (6.6 t.ha-1), cow dung at 30 t.ha-1 (5.4 t.ha-1) and urea at 100 kg.ha-1 (5.4 t.ha-1), while control recorded lower values. A significant quadratic response on fresh leaf yield was observed with MSWC leading to a maximum of yield of 8.15 t.ha-1 at 23.03 t.ha-1.Conclusion and application of results: The results indicated that the MSWC performs better when used at the optimal rate (23.03 t.ha-1), and can be used as a promising fertilizer source in Corchorus olitorius production in Benin.Key words: Leaf yield, waste compost, cow dung, Corchorus olitorius, Beni

Verbal communication disorders in brain damaged post-stroke patients in Benin

AbstractIn Western countries, progress has lessened the severity of numerous sequels of verbal communication disorders (VCD). For Africa and more particularly Benin, few data on the subject are presently available.ObjectiveTo analyze the occurrence and development of post-stroke VCD in Benin.MethodA retrospective, descriptive and analytical study focused on 563 post-stroke patients treated in rehabilitation department of the National university hospital of Cotonou (CNHU) from January 2006 through December 2010.ResultsVCD prevalence was 42.10%. Average age was 57.17±12.62years, sex ratio was 1.75, and 74.69% were right-handed. VCD affected oral expression (95.78%), written expression (2.11%), oral comprehension (13.08%) and written comprehension or reading (0.84%). Type of stroke, sex and age had no impact on VCD occurrence following stroke. Only 5.91% of the patients underwent speech therapy. Progression was favorable in 21.09% of the cases studied.ConclusionIn Benin, post-stroke VCD is exceedingly common and occasions major social difficulties. Prevalence of VCD in a predominantly oral culture underscores the need for speech therapists to develop a more broadly ecological approach toward treatment
