Objectif: La presente etude visait a trouver une alternative a l’utilisation des engrais de synthese dans la culture du bananier plantain. Methodologie et resultats: Pour ce faire, des formulations d’engrais organiques ont ete mises au point. Notamment, F2 constitues de 100 % de pelure de banane sechee et broyee (PBSB), F3, F4 et F5 constituees respectivement de 75 %, 50 %, 25 % de PBSB + 25 %, 50 % et 75 % de compost de fiente de poules (CFP). Les proprietes chimiques de ces formulations ont ete determinees, puis leur effet sur la croissance des rejets ecailles de bananier plantain a ete evalue comparativement a l’effet du NPK (20-10-10) et le temoin F0. L’experimentation a ete realisee selon un dispositif en bloc de Fisher comportant 6 traitements avec 4 repetitions. Les applications ont ete faites chaque mois et le suivi a porte sur la croissance en hauteur, la circonference du pseudo-tronc et le nombre de feuilles. L’analyse minerale a permis de classer les fertilisants organiques en deux groupes : les plus riches (F4 et F5) et les moyennement riches (F2 et F3). Concernant les donnees de croissance, l’analyse statistique indique que les fertilisants organiques ont induit une bonne croissance (H = 13,77 cm, C = 2,93 cm, NF = 8) des plants de bananiers par rapport au temoin F0 (H = 8,45 cm, C = 1,55 cm, NF = 7) et a l’engrais mineral (H = 6 cm, C = - 0,2 cm, NF = 5). Conclusion et application des resultats: Cette etude a montre que l’utilisation de la pelure de banane plantain sechee et broyee (PBSB) simple ou en melange avec le compost de fiente de poules (CFP) induit une croissance harmonieuse du bananier plantain. La PBSB peut etre une alternative a l’utilisation des engrais chimiques et etre recommandee aux agriculteurs.

Methodology and results: For that to make, formulations of organic manures have been finalized. Notably constituted F2 of 100% of banana peel dried and ground (PBSB), F3, F4 and constituted F5 respectively of 75%, 50%, 25% of PBSB + 25%, 50% and 75% of compost of droppings of hens (CFP). The chemical properties of these formulations have been determined, and then their effect on the growth of the dismissals scales of banana trees plantain has been valued compared to the effect of the NPK (20-10-10) and witness F0. The experimentation has been achieved according to a device in block of Fisher including 6 treatments with 4 repetitions. The applications have been made every month and the follow-up was about the growth in height, the circumference of the pseudo-trunk and the number of leaves. The mineral analysis permitted to classify the fertilizing organic in two groups: the richest (F4 and F5) and the rich (F2 and F3). Concerning the data of growth, the statistical analysis indicates that the fertilizing organic led a good growth (H = 13.77 cm, C = 2.93 cm, NF = 8) of the plantations of banana trees in relation to witness F0 (H = 8.45 cm, C = 1.55 cm, NF = 7) and to the mineral manure (H = 6 cm, C = - 0.2 cm, NF = 5). Conclusion and application of results: This survey permitted to show that the use of the peel dried banana plantain and ground (PBSB) simple or in mixture with the compost of droppings of hens (CFP) induced a harmonious growth of the banana tree plantain. The PBSB can be an alternative to the use of the chemical manures and can recommend to the agriculturists. Keywords: Banana plantain, peel, organic manures, mineral manures |
