ENTRY BEHAVIOUR/ PREVIOUS KNOWLEDGE: the students are familiar with classification of crops according to form.
CLASSIFICATION OF CROPS ACCORDING TO LIFESPAN
Life span is the period a crop spends from germination till it dries up. There are three main classes of such crops. Crops may be grouped according to lifespan.
- Annual Crops: these are crops grown from seed to mature plant in a growing season or a year. That is they produced germinate, produce fruits and die within one year. Examples are maize, rice, beans, groundnut, tomato millet and guinea corn.
- Biennial Crops: these are crops grown from seed to mature plant in two seasons or two years. That is these crops grow for more than one year but they die before the end of the second year. Examples are cassava, cabbage, onion, sugarcane, pepper.
- Perennial Crops: they are crops grown from seed to mature plant in three to five years or more that is these grow for more than two years, and continue to bear fruits for many more years. Most of them are tree crops e.g. oil palm, cacao, rubber, cashew, mango, coconut, kola nut and orange, banana.
CLASSIFICATION OF CROPS ACCORDING TO USE AND TYPE
Crops are grown for different uses. On the basis of type, we have the following;
- FOOD CROPS: these are crops that we eat. The following are food crops:
- CEREALS: These are crops that produce grains or seeds rich in carbohydrate e.g. Wheat, millet, rice, maize, corn, guinea, sorghum. Cereals are Grain crops.
- LEGUMES: legumes produce seeds that are rich in protein. They bear their seeds inside the pods and they enrich the soil with nutrient (nitrogen) thereby improving soil fertility. Examples are soyabeans, groundnuts, cowpeas.
- VEGETABLES: vegetables are edible leaves or fruits that may be cooked before eating e.g waterleaf, okro, bitterleaf, amaranthus, corchorus (ewedu).
- FRUITS: fruits gives us vitamins and minerals. Fruits may be eaten without cooking them. E.g coconut, mango, orange, cashew, banana, pineapple.
- CASH CROPS: These are crops exported for income. These are:
- Latex crops: these crop produce sap that is converted to raw rubber used in making tyres. E.g. rubber tree.
- Beverage crops: these are crops that produce food drinks. They are used to make cocoa drinks and chocolates. Examples are coffee and tea.
- SPICE CROPS: these are crops that give our cooking very sweet aroma and make it taste delicious. E.g tomatoes, ginger, pepper, onion.
- ROOT AND TUBER CROPS: they have swollen edible, underground stems or roots. E.g. cassava, cocoyam, potato, yam, carrot.
- OIL CROPS: Oils are gotten from palm oil, melon, coconut, cotton, and groundnut. Oils are used in cooking, in making soap.
- DRUG CROPS: they are used to cure diseases and wounds. E.g. neem (dogonyaro), eucalyptus.
- FIBRE CROPS: these crops produce materials for weaving clothes, bags and sacks. Examples are jute, sisal, kenaf, cotton.
- FORAGE CROPS: they are plants/grass gown for feeding animal’s e.g. guinea grass, elephant grass, pueraria and centosema.
- ORNAMENTAL CROPS: Ornamental crops are grown to beautify surroundings e.g. rose flower, cotton, hibiscus flower, red acalypha.

- The Teacher introduces the topic (CLASSIFICATION OF CROPS ACCORDING TO LIFESPAN).
- The Teacher explains the lessons.
- Learners participate in the class discussion
- Learners observe some rock samples
- Mention three Classification of crops and their uses according to life span.
CONCLUSION: the teacher summarize the lesson.
