This article follows on from two articles published in 2014 and 2018 on the same trial conducted in an oil palm plantation in Nigeria which was aimed at assessing a range of different planting distances between oil palms (7.5 to 9.5 m) in an equilateral triangle design. The climate in the region is very stable, with two seasons and an average 2000 mm of rainfall per year. The soil is of the desaturated ferralitic type, sandy on the surface, deep, and without coarse elements. After continually monitoring the experimental palms for 16 years, there is now enough hindsight to propose an optimum planting density for oil palms in Western Africa. A plateau has been reached at between 143 and 160 palms per hectare for Pobè C1001F material in the aforementioned pedoclimatic context.
Résumé
Cet article fait suite à deux articles publiés en 2014 et en 2018 sur la même expérience conduite dans une palmeraie au Nigéria, ayant pour but de tester différentes distances de plantation entre palmiers (7,5 à 9,5 m) dans un dispositif en triangle équilatéral. Le climat de la zone est très stable, à deux saisons et une moyenne de 2000 mm de précipitations par an. Le sol est du type ferrallitique désaturé, sableux en surface, profond et sans éléments grossiers. Après un suivi continu des palmiers expérimentaux pendant 16 ans, nous avons maintenant suffisamment de recul pour proposer une densité de plantation optimale en Afrique de l’Ouest. Nous avons atteint un plateau s’étendant de 143 à 160 palmiers à l’hectare pour le matériel végétal Pobè C1001F dans le contexte pédoclimatique décrit ci-dessus.
