Utilisation des biofertilisants extrais d’Azolla sur la culture de l’aubergine (Solanum Melongena L.).

Abstract

This study examined the impact of fermented azolla and powdered azolla as biofertilizers on eggplant cultivation, in comparison with chemical NPK fertilizer. The experiment was conducted in pots under controlled conditions, with six distinct treatments: the application of different doses of fermented azolla (25 g, 50 g, 75 g) and powdered azolla (25 g, 50 g, 75 g), as well as two control groups (a positive control using NPK and a negative control without fertilizer). The results indicated that eggplant plants treated with fermented azolla exhibited more vigorous growth compared to the controls. The average stem height reached 36.11 cm with fermented azolla, compared to 22.11 cm for the unfertilized control and 30.89 cm for the NPK control. Regarding flowering, fermented azolla resulted in an average production of 15.6 flowers per plant, surpassing the 11.1 flowers observed with NPK. In terms of leaf count, plants treated with fermented azolla produced an average of 21.44 leaves per plant, closely comparable to the 22.89 leaves achieved with NPK. In terms of yield, fermented azolla recorded an average weight per plant of 115.11 g, showing a significant increase compared to the 75.67 g obtained with NPK, thus demonstrating its effectiveness as a biofertilizer. Powdered azolla, applied at a dose of 75 g, also showed competitive performance, with an average weight of 92.33 g per plant. These results suggest that fermented azolla serves as an ecological and sustainable alternative to chemical fertilizers, promoting environmentally friendly agricultural practices.
