CONTENTS OF THE LESSON

FOCUS LESSONS 

CLASSIFICATION OF CROPS

Crops can be classified based on forms, life span. uses and sources of nutrients.

FORMS  – MONOCOTYLEDONOUS AND DICOTYLEDONOUS 

1. Monocotyledonous is a plant with the seed having only one cotyledon. Examples of Monocotyledonous – maize, guinea corn, ginger, banana, wheat, palm, onion, garlic, etc.

2. Dicotyledonous is a plant with the seed having only one cotyledon. Examples of Dicotyledonous – bean, melon, groundnut, potato, tomato, pea, hibiscus, etc.

LIFE SPAN – ANNUAL, BIENNIAL AND PERENNIAL CROPS 

1. ANNUAL CROPS 

These are crop that complete the life cycle within a year. For examples, maize, yam, etc.

2. BIENNIAL CROPS 

These are crop that complete the life cycle within a year. For examples, ginger, pineapple, cassava, etc.

3. PERENNIAL CROPS 

These are crop that complete the life cycle within a year. For examples, cocoa, mango, orange, etc.

USES OF CROPS

1. It is used for production of food. For examples – Cereals, Tubers (yam, cassava and potatoes), Pulses, Fruits and vegetables (potatoes, tomatoes, and onions)

2. It is used for oil production. For examples – Palm, Soybean and Groundnut.

3. It is used for the production of spices. For examples – Tomatoes, Onions, Ginger, Chili powder, Black pepper and Cinnamon.

4. It is used for the production of beverage. For examples – Tea, Coffee and Cocoa

5. It is used for the production of fiber. For examples – Cotton, Jute, Kenaf, Hemp, Ramie and Sisal.

SOURCE OF NUTRIENTS

1. Carbohydrates are energy given food and found in food like rice, noodles, bread and other products that have grains.

2. Fats and oils are for growth and function normally and help with tissue growth. They are found in foods like meat, fish, whole eggs, vegetables, nuts.

6. Water support life and needed on regular basis.
