Abstract


The study has been initiated with the aims to evaluate effects of manure application on the yield of Irish potato. The experiment was conducted at (INERA) Mulungu using in a Complete Random Block with three replicates. Five treatments have been evaluated such as: application of DAP during planting, application of N+KCK three time as follow: once per week, once per two weeks and onceper three weeks together with a natural check without fertilizer. The results showed that DAP and N+KCL applied once per week have improved the yield up to 128.5% in comparison to the check, however N+KCL applied once per two and three weeks have increased the yield from 51.7 to 62.9% compared to the natural check. The results show that farmer having Irish as one of his activities can be interested to increase the productivity.

Author Keywords: Effect, frequency, manure, irish potato.


Abstract: (french)


Ce travail a été initié dans le but d’évaluer les effets de fréquence d’application des engrais sur le rendement de pomme de terre. L’essai a été conduit suivant un dispositif en bloc complet randomisé à 3 répétitions. Cinq traitements ont été évalués à savoir : DAP appliqué à la plantation, N+ KCl appliqués 1 fois / semaine, 1 fois / 2 semaines, 1fois/ 3semaines et le témoin naturel (sans amendement). Les résultats obtenus montrent que le DAP et N + KCl appliqués 1 fois/semaine ont amélioré le rendement jusqu’à 128,5% par rapport au témoin. Par contre le N + KCl appliqués 1 fois / 2 semaine et 1 fois / 3 semaines ont augmenté le rendement de51,7 à 62,9% par rapport au témoin naturel. Ces résultats montrent que l’agriculteur qui a la pomme de terre dans ses activités peut s’y intéresser pour accroitre la production.

Author Keywords: Effet, fréquence, engrais, pomme de terre.
