Abstract

In order to minimize production losses, and limit the use of chemicals, several organic products have been developed. The objective of this study is to assess the effect of biostimulant Banzai and fertilizer on cocoa tree productivity. Conducted in the department of Toumodi, this study took place in one device with a cocoa field that has received fertilizer in the last three years (DAE) and another that has received no fertilizer in the past three years (DSE). The results obtained showed that the plots that had been applied to Banzai produced significantly more pods than the control plots without application of the biostimulant. Compared to controls, the production rate of pods is greater than between 38 and 70% in the unprecedented fertilizer plots (DSE) and between 51 and 80% in plots with previous fertilizer (DAE). However, the production of pods in treated plots is more than three times high in the DAE than in the DSE. This study shows the positive impact of biostimulant use on cocoa yield. In addition, it shows that the use of fertilizers during the experiment could be abandoned with a view to greater use of organic products at the expense of chemicals that have a detrimental effect on the environment and on the long-term health of populations.

Highlights

Theobroma cacao L. is a tree of the Malvaceae family grown in many countries in the intertropical zone of America, Africa and Southeast Asia [1]
Over the entire observation period, the production of pods in plots treated with biostimulant Banzai is higher than that of untreated controls (T01 and T02)
The plots that received the application of biostimulant Banzai have significantly produced more pods than the control plots that are without application of the biostimulant

Summary

Introduction

Theobroma cacao L. is a tree of the Malvaceae family grown in many countries in the intertropical zone of America, Africa and Southeast Asia [1]. It is grown for the production of seeds used to prepare chocolate or cocoa butter [2]. The cocoa sector plays an essential role in Côte d'Ivoire's economy. It is one of the main sources of income in the country [3,4,5]. Many constraints lead to a considerable decline in Ivorian cocoa production [8]. Abiotic factors related to market price fluctuations and forest scarcity, and on the other hand, factors related to the action of diseases and pests of cocoa which are prevalent in all regions [8,9]
