Polysulphate Cocoa Trial
Objectives & Treatments
To investigate the effect Polysulphate has on the yield of mature cocoa trees and to compare it with a comparable granular NPK fertilizer which also contains calcium, magnesium, and sulfur. The study was conducted by the Cocoa Research Institute of Ghana (CRIG) in 2020/21 and 2021/22 cocoa seasons on farms at 4 locations. The trial utilized a randomized complete block design, incorporating 3 treatments and 2 replicates per location. The ages of the mixed hybrid cocoa variety trees ranged from 10 to 15 years. Treatment 1 was the unfertilized control, treatment 2 was the reference granular fertilizer (NPK 0-22-18+9CaO+9MgO+7S) applied at 375 kg/ha per year, treatment 3 was Polysulphate granular fertilizer applied at 375 kg/ha per year. All recommended agronomic practices were followed.
Trial results
Polysulphate significantly increased the two-year cumulative dry cocoa bean yield at 3 of the 4 locations.

On average, Polysulphate increased the dry bean yield by 13.6% compared with the reference granular fertilizer and by 70.8% compared with the unfertilized control.

Based on these results, Polysulphate is considered suitable for mature cocoa plantations at the application rate of 375 kg/ha.
