Explanation
Production of cocoa (a) Method of propagation: (i) This is done mainly by seed (ii) it can be grown vegetatively by buddng and stem cutting. (b) Climatic and soil requirements: (i) needs an annual rainfall of at least 1140 mm 2000 mm. (ii) a mean temperature of 17°C - 21°C. (iii) requires deep, fertile and well aerated loamy soil.

(e) Method of harvesting: (i) a sharp sickle cutlass is used to cut the stalk off the pod without damage to the flower cushion. (f)(i) Major diseases and their control: (1) black pod disease caused by the fungus Phytphora palmivora. (2) swollen shoot disease transmitted mealy bugs. (ii) Control of diseases: cocoa black pod: regular spraying with fungicide e.g perenox , removal infected pods, burning of infected pods. swollen shoot disease: planting resistant varieties , destruction of infect trees, spraying trees with insecticide or destruction of vectors, mealy bug with insecticide.
