This study concerns the phytotoxicity test of a compost prepared with calcined Tahoua phosphate in order to increase its solubility. To do this, a test was carried out on two crops: corn and peanuts. For each crop, four treatments were carried out: control To made up of sand, T1 containing 1/4 compost and 3/4 sand, T2 made up of 3/4 compost and 1/4 sand, T3 made up of compost alone. The experiment was carried out in pots arranged in blocks with three repetitions. After 10 days of incubation, the maturity of the compost was evaluated according to the percentage of germination of the treatments compared to the control. The results made it possible to obtain a germination rate of 100% with maize and 122% with peanut for the T1 treatment. For the T2 treatment, the germination rate is 100% with maize and 88.89% with peanuts. As for the T3 treatment, the germination rate is 111% for maize and only 22.22% with peanuts. These results show that the calcination of merchant phosphate from Tahoua does not lead to the formation of phytotoxic products for plants.
Author Keywords: Calcined phosphate, sprouting, peanut, corn, compost, phytotoxicity.

Abstract: (french)
Cette étude porte sur le test de phytotoxicité d’un compost préparé avec le phosphate calciné de Tahoua afin d’accroitre sa solubilité. Pour ce faire, un test a été effectué sur deux cultures: le maïs et l’arachide. Pour chaque culture quatre traitements ont été réalisés: témoin To constitué de sable, T1 contenant 1/4 du compost et 3/4 du sable, T2 composé de 3/4 compost et 1/4 de sable, T3 constitué du compost seul. L’expérimentation a été conduite dans des pots disposés en blocs avec trois répétitions. Après 10 jours d’incubation, la maturité du compost a été évaluée suivant le pourcentage de germination des traitements par rapport au témoin. Les résultats ont permis d’obtenir un taux de germination de 100 % avec le maïs et 122 % avec l’arachide pour le traitement T1. Pour le traitement T2, le taux de germination est de 100 % avec le maïs et 88,89 % avec l’arachide. Pour ce qui du traitement T3, le taux de germination est 111 % pour le maïs et seulement 22,22 % avec l’arachide. Ces resultats montrent que la calcination du phosphate marchand de Tahoua n’entraine pas la formation des produits phytotoxiques pour les plantes.
