Management of coconuts and cocoa on acid sulphate soils
The yield performances of underplanted cocoa and a mixture of dwarf and hybrid coconuts in fields on acid sulphate and non-acid sulphate areas in three coastal estates were compared. The cocoa yields under the heavy shade of coconuts were about 365 to 465 kg per ha per year in the acid sulphate areas against 732 kg per ha per year in comparable non-acid sulphate areas. Coconut yields were 1762 to 2095 kg copra per ha per year against 2439 kg copra per ha per year respectively. Liming from pH 3.9 to pH 4.5 in the topsoil increased copra content per nut and copra yields by 10 per cent and nearly doubled cocoa yields. Management practices including fertiliser applications, leaf and soil analytical data and water management practices are also described and discussed.
