Côte d'Ivoire, a West African country, is the world's leading cocoa producer. However, cocoa tree diseases and pests are rampant in all regions and can cause production losses of up to 60%. In order, to minimize production losses, several types ofbiostimulants have been put in place, including the Banzaï biostimulant. The objective of this study is to know the effect of the biostimulant Banzaï and the previous fertilizer on the production of cherries in the locality of N'gouanmoinkro. This study was carried out according to two devices, a device comprising a field of cocoa trees who received a fertilizer input during the last three years (DAE) and another without fertilizer input received during the last three years (DSE) preceding the year of experimentation. The results obtained showed that the plots that received the biostimulant Banzaï produced significantly more cherries than the control plots on which there was no application of the biostimulant. Indeed,compared to the controls, the production rate of cherries is more between 33to 70% in the plots without unprecedented fertilizer (DSE) and between 23to 46% in the plots with previous fertilizer (DAE). However, the production of cherries is more than twice as high in the DAE as in the DSE. This study clearly shows the impact of the use of biostimulants andfertilizers on the yield of cocoa trees and can be used in the fight against the limitation of damage produced by pests and diseases of cocoa trees in Côte d'Ivoire.
