(b) Physical conditions necessary for cocoa production

1. Temperature: Cocoa requires a uniformly high temperature of about 27°C, with a low annual temperature range and no frost.
2. Rainfall: It requires moderate to heavy rainfall of about 125 to 200 cm annually, fairly well distributed through the growing season.
3. Soil and relief: It grows best on deep, fertile, humus-rich and well-drained loamy soil, usually on gently undulating land.
4. Shade and dry period: Young cocoa seedlings need shade. A short dry season, especially from December to February, assists the drying of harvested beans.

(c) Importance of cash crops to the economy of Nigeria

1. Foreign exchange and revenue: Export crops such as cocoa earn foreign exchange for Nigeria and provide revenue to government through taxes and export duties.
2. Employment and income: They provide employment and income for farmers, farm labourers, produce buyers, transporters and traders.
3. Raw materials: They supply raw materials to industries, for example cocoa to beverage and confectionery industries, cotton to textile industries and rubber to tyre industries.
4. Development of settlements: Cash-crop production promotes roads, markets, processing centres and the growth of towns in producing areas.
