Abstract
Despite the fact that early planting is the key to high returns (Akehurst, 1961 and 1965), many small-scale farmers plant their tobacco after the optimum date of mid-November to mid-December. Observation and experience indicate a number of valid reasons for this. While the farmer may have to wait for the rains before he can work the soil with his simple hoe, there is also a natural tendency for him to delay planting until he is certain that the rainy season has actually begun. In recent years, however, the main reason for an increase in late planted tobacco has been competition for labour with food crops, particularly maize.
