The objective of this survey is to contribute to the promotion and the production of the Azolla fern while increasing his/her/its quantity and his/her/its quality in the ecological conditions with the available and renewable matter to meet the expectation of the users. To achieve this work, the droppings of chicken have been appropriated and conditioned as filtrate to act as nourishing element to the culture of Azolla filiculoides and Azolla caroliniana. The gotten filtrate is constituted of primary nourishing elements (NO3- (34gm/L), NH4+ (5,99gm/L), PO43- (265gm/L) and 1227,22gm/L of K), of secondary nourishing elements (47,57gm/L of Ca, 28,35gm/L of Mg, 218,36gm/L of Na and 720,10gm/L of SO42) and of trace elements (0,56gm/L of Cu, 11,69gm/L of Fe and 1,18gm/L of Mn.). Then, the Azolla ferns have been harvested after 15, then weighed 23 and 29 days and dried to the shade during five days before being analyzed. The results show that the production of Azolla filiculoides and Azolla caroliniana is influenced by the length of culture because the production harvested after 15 days is different from the one gotten after 23 and 29 days, for each of the Azollas, but 23 days are revealed the interesting culture length for his/her/its harvest. To 23 days, the harvested middle quantity is of 6737,03g for Azolla caroliniana and 6754,45g for Azolla filiculoides. The middle length of their root is identical, about 2 cm. However, the analysis of the physico-chemical composition of Azolla caroliniana proves to be better that the one of Azolla cultivated filiculoides with the same filtrate and in the same conditions.

Abstract: (french)
L’objectif de cette étude est de contribuer à la promotion et à la production de la fougère Azolla en augmentant sa quantité et sa qualité dans les conditions écologiques avec de la matière disponible et renouvelable pour répondre à l’attente des utilisateurs. Pour réaliser ce travail, de la fiente de poulet a été prélevée et conditionnée sous forme de filtrat pour servir d’élément nutritif à la culture d’Azolla filiculoides et d’Azolla caroliniana. Le filtrat obtenu est constitué d’éléments nutritifs primaires (NO3- (34gm/L), NH4+ (5,99gm/L), PO43- (265gm/L) et 1227,22gm/L de K), d’éléments nutritifs secondaires (47,57gm/L de Ca, 28,35gm/L de Mg, 218,36gm/L de Na et 720,10gm/L de SO42) et d’Oligo-éléments (0,56gm/L de Cu, 11,69gm/L de Fe et 1,18gm/L de Mn). Ensuite, les fougères Azolla ont été récoltées après 15, 23 et 29 jours puis pesées et séchées à l’ombre pendant cinq jours avant d’être analysées. Les résultats montrent que la production de Azolla filiculoides et Azolla caroliniana est influencée par la durée de culture car la production récoltée après 15 jours est différente de celle obtenue après 23 et 29 jours, pour chacune des Azolla, mais 23 jours se révèle la durée de culture intéressante pour sa récolte. A 23 jours, la quantité moyenne récoltée est de 6737,03g pour Azolla caroliniana et 6754,45g pour Azolla filiculoides. La longueur moyenne de leur racine est identique, environ 2 cm. Cependant, l’analyse de la composition physico-chimique d’Azolla caroliniana se révèle meilleure que celle d’Azolla filiculoides cultivée avec le même filtrat et dans les mêmes conditions.
