Efficiency of Banzai Biostimulant on the cherries production in healthy and cocoa trees affected by swollen shoot virus: A case study at Petit-Bondoukou Côte d'Ivoire

The present study is to evaluate the efficiency of the Biostimulant "Banzai" on the production of cherries from healthy anddiseased trees in a context of pressure from Swollen shoot cocoa disease in Petit-Bondoukou in the department of Soubré. Thespecific aim is to compare the effect of the single and double doses of Banzai on the production of cherries from healthy anddiseased trees. The experimental design consists of a single block of four plots marked T0 (Control), T1 (a standard rate Banzaiapplication without fertilizer), T2 (a double rate Banzai application without fertilizer) and T3 (a standard rate Banzai applicationwith fertilizer). Each plot contains ten healthy trees and ten trees with swollen shoot disease. This device was repeated four timesat the study site. Banzai was applied for four months and observations were made for six consecutive months on the number ofcherries produced. The results of the Kruskal-Wallis test showed that the treated plots produced significantly more cherries thanthe control plots in both healthy and diseased trees at any dose. In addition, in healthy trees, the Kruskal-Wallis test showed thatthe single dose of Banzai without fertilizer (T1) significantly produced more cherries than other treatments. While in diseasedtrees, the Kruskal-Wallis test showed that the double dose of Banzai without fertilizer (T2) significantly produced more cherriesthan other treatments
