CONTENT OF THE LESSON  

INTRODUCTION

Farmers plant many crops for different reasons. They plant for foods or commercials. Crops are classified according to forms and lifespan and according to types and uses.

Crops include maize, rice, tomato, pepper, okro, kolanut, beans, groundnut, etc.

CLASSIFICATION OF CROPS BASED ON THEIR USES

There are many kinds of crops which can be classify according to types and uses as follows –

1. Cereals

2.Pulses/Legumes

3. Roots and Tubers

4. Vegetables

CEREAL CROPS 

These crops produce grains. Rice, wheat, maize, guinea corn, millets, etc. are examples of cereal crops.

 

LEGUME CROPS 

These produce pods that bear seeds in rows. Soybean, pea, peanut, cowpea, etc. are examples of legume crops.

 

TUBER CROPS 

These crops are root crops. Potato, yam, cassava, Irish potato, etc. are examples of tuber crops.

 

FRUIT CROPS 

Fruits crops produce mainly fruits. Orange, mango, pawpaw, apple, pineapple, banana, etc. are examples of fruits

 

VEGETABLES CROPS 

Vegetables produce leaves, fruits and roots as food. Tomato, cabbage, okro, pepper, onion, carrot, etc. are examples of vegetables.

CLASSIFICATION BASED ON THEIR LIFE CYCLE

Crops can be grouped according to their life span as follows –

1. Annual

2. Biennial

3. Perennial

4. Ephemeral

ANNUAL CROPS 

Annual crops are crops that grow and live for about one year.

Maize, okro, onion and carrot, yam, maize, rice, groundnut, millet, garden egg, sorghum, cassava and potato are examples of annual crops.

BIENNIAL CROPS 

Biennial crops are crops that grow and live for about two years.

Pepper, alligator pepper, plantain, sugarcane, pineapple and pawpaw are are examples of biennial crops.

PERENNIALS CROPS 

Perennial crops are crops that grow and live for more two years.

Oil palm, cocoa, mango, citrus, guava and kola are examples of perennial crops.

EPHEMERAL CROPS 

These are crops marked by short life cycles. That’s, these crops germinate, produce seeds, flower, and die. For examples, tomatoes, etc.

CLASSIFICATION BASED ON THEIR MORPHOLOGY

There are two major forms of crop plants –

1. Monocotyledon Crops

2. Dicotyledonous Crops

MONOCOTS

These crops are also known as monocotyledons or monocotyledonous crops.

The crops have one seed leaf after germination.

An example is the maize seedling.

DICOTS

These crops are also known as dicotyledons or dicotyledonous.

The crops have two seed leaf after germination.

An example is the bean seedling.

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the students some questions; then, the teacher –

2. Display of a collection of crops seeds, fruits or leaves.

Student’s Activities – Observe and note the differences and group that each belongs.

3. Discuss the classification of crops with the students by encouraging active participation.

Student’s Activities – Participate actively in the class discussion.

4. Summarizes the lesson on the board.

Student’s Activities – Copy as the teacher writes.

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

LESSON EVALUATION 

Ask students to:

Identify and classify crops based on

1. uses,

2. lifecycles, and

3. morphology.
