The study of organic manure should not only be limited to the analysis of its effects on crop development and yield, but should also extend to the examination of its impact on maintaining or increasing soil fertility. A trial was conducted in Ngandajika on the residual effects or nutrient dynamics of two organic materials, cow dung and Tithonia diversifolia. At the end of this trial, the following results were recorded, the T2 treatment or the dung nutrient dynamics gave the yield of 2.87 T/ha and 3.16 T/ha respectively in maize monoculture and in maize-cowpea association, which are significantly higher than that achieved with T1 or Tithonia diversifolia nutrient dynamics 2.27 T/ha and 2.55 T/ha and the latter more than the control (1.41 T/ha and 1.63 T/ha). Thus, we can therefore remember that the nutrient dynamics of cow dung are stronger than those of Tithonia diversifolia on the maize crop more than on the control. Both organic manures with their element dynamics not only increase the yield of maize cultivation, they also increase soil fertility.

Abstract: (french)
L’étude d’une fumure organique ne doit pas uniquement se limiter à l’analyse de ses effets sur le développement et le rendement des cultures, elle doit aussi s’étendre à l’examen de son impact sur le maintien ou l’accroissement de la fertilité du sol. Un essai a été effectué à Ngandajika sur les effets résiduels ou la dynamique d’éléments nutritifs de deux matières organiques, la bouse de vache et le Tithonia diversifolia. A l’issue de cet essai, les résultats ci-après, ont été enregistrés, le traitement T2 ou la dynamique d’éléments nutritifs de la bouse donne le rendement de 2,87T/ha et 3,16T/ha respectivement en monoculture de maïs et en association maïs-niébé, qui sont significativement plus élevé que celle réalisée avec T1 ou dynamique d’éléments nutritifs de Tithonia diversifolia 2,27T/ha et 2,55T/ha et celui-ci plus que le témoin (1,41T/ha et 1,63T/ha). Ainsi donc, on peut donc retenir que la dynamique d’éléments nutritifs de la bouse de vache est plus forte que celle de Tithonia diversifolia sur la culture du maïs celui-ci plus que sur le témoin. Les deux fumures organiques avec leurs dynamiques d’éléments augmentent non seulement le rendement de la culture du maïs, ils accroissent aussi la fertilité du sol.
