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.
