Presentation

Step 1: What is Crop?
Crops is any plant deliberately planted by a man for use as food for himself, feed for his livestock, or other uses such as to obtain fibre to make clothes.

Step 2: Uses of Crops
The uses of crops are one basis for their classification on grouping.

We shall classify crops according to their uses. In this type of classification, some crops will fall in more than one group because they have more than one use.

1. Food and Feed Crops
These are crops used by man fro food for himself and his livestock.

• Cereal grains: They include maize, sorghum (guinea corn), millet, rice, wheat.
• Roots and tubers: They include cassava, sweet potatoes, yams, Irish potatoes, coco yam.
• Oil crops: Examples are groundnuts, oil palm, soybeans, sunflower, sesame (beniseed), coconut, Shea nut, cotton seed and cashew.
• Grain legumes: They include soybeans, cow pea, groundnuts.
• Fruits: Examples are mango, orange, banana, cashew, pawpaw, guava, pineapple.
• Vegetables: Examples are Okra, water leaf, bitter leaf, cabbage, lettuce and onions.
• Sugar crops: Sugar cane and sugar beet.
• Spices: Pepper, ginger and locust bean
• Beverages and stimulants: cocoa, tea, coffee, kola nut and tobacco.
• Forage crops: They are grown solely as feed for farm animals. Elephant grass, gamba grass and alfalfa. Most of the food crops can be grown as forage crops, in which they are harvested before maturity. Such crops include maize, sorghum, millet, groundnuts, soybeans and cow-pea.

2. Industrial Crops
These are crops whose products are used as raw materials for manufacture of various things which we use.

• Fibre crops: They are used for making cloth, sacks, carpets, twines and ropes
• Latex and gum crops: Examples are rubber and gun arabic.
• Drugs and insecticides: They include cocaine, quinine pyrethrum and opium.
• Starch crops: Their products are used in the manufacture of starch. The cereal grains are also used in beer brewing.
• Oil crops: These crops are used in the manufacture of soaps, paints and varnishes. These include oil-palm, soybeans, coconut, sheanut, castor bean, cotton and cashew.

3.Ornamental Crops:
These are crops grown to decorate our surroundings. They include various flowers and house plants, hedge shrubs and lawn grasses.

Evaluation:
To ascertain their level of understanding, the teacher will ask the learners the uses of farm crops.

Homework:

1. What is crop?
