Classification of Crops based on Life Span
Crops complete their processes of growth at different lengths of time. Hence, crops can be classified as follows – annual, biennial and perennial.
Annual Crops
Annual crops are crops which complete their life cycle (length of life) within one year or in one growing season. These crops grow into maturity, flower, produce seeds and eventually die within one year. Examples are maize, rice, sorghum, soya-beans, guinea corn, cowpea, sweet potato, cotton, tomato, yam, etc.
