This study was carried out with the aim of evaluating the impact of the contributions of organic fertilizers (Tithonia diversifolia, Batguano) on the growth and yield of maize cultivation in monoculture and in association with cowpea. From this study, the following results were recorded: In monoculture, Bat-guano gives a yield of 4.18 T/Ha significantly higher than Tithonia diversifolia with 3.73 T/Ha in the QPM3 variety; 3.82 T/Ha against 2.43 T/Ha with the Mus1 variety. In maize-cowpea association, Bat-guano gives the yield of 3.19 T/Ha significantly higher than Tithonia diversifolia with 2.77T/Ha in the QPM3 variety, 2.89 T/Ha against 1.40 T/Ha with the variety Mus1. The study that was conducted highlights a clearly beneficial effect of the use of natural fertilizers, namely Tithonia and bat guano, on the cultivation of maize in monoculture as well as in association with cowpea. Data analysis indicates that the treatment with bat-guano was found to be the manure capable of significantly improving the vegetative and yield components of grain maize compared to tithonia. In general, both treatments had higher yields compared to the control (F0).

Abstract: (french)
Cette étude a été réalisée dans l’objectif d’évaluer l’impact des apports des fertilisants organiques (Tithonia diversifolia, Batguano) sur la croissance et le rendement de la culture du maïs en monoculture et en association avec le niébé. De cette étude, il a été enregistré les résultats ci-après: Dans la monoculture, le Bat-guano donne le rendement de 4,18T/Ha significativement plus élevé que le Tithonia diversifolia avec 3,73 T/Ha dans la variété QPM3; 3,82 T/Ha contre 2,43 T/Ha avec la variété Mus1. En association maïs-niébé, le Bat-guano donne le rendement de 3,19 T/ Ha significativement plus élevé le Tithonia diversifolia avec 2,77T/Ha dans la variété QPM3, 2,89 T/Ha contre 1,40 T/Ha avec la variété Mus1. L’étude qui a été menée, met en évidence un effet nettement bénéfique de l’utilisation des fertilisants naturels à savoir le Tithonia et le bat guano sur la culture du maïs en monoculture comme en association avec le niébé. L’analyse des données indique que le traitement au bat-guano s’est révélé être la fumure susceptible d’améliorer significativement les composantes végétatives et de rendement du maïs grain par rapport au tithonia. D’une manière générale, tous les deux traitements ont eu des rendements plus élevés par rapport au témoin (F0). Les deux peuvent ainsi être utilisés pour accroître la fertilité du sol et augmenter de façon significative les rendements de cultures et par conséquent contribuer à l’amélioration de la production de maïs.
