Reference Materials

The following resources was used in planning this lesson:

9 Years Basic Education Curriculum
Lagos State Unified Scheme of work for Junior Secondary Schools
Wikipedia – Plant propagation
Relevant Textbooks

Instructional Materials

The teacher will teach this lesson with the aid of:

Samples of seeds (maize, beans, groundnut)
Cuttings of stem, root and leaf from crops like cassava, yam and sweet potato
Chart showing methods of propagation
Hoe, watering can and small containers with soil
Whiteboard and markers

Rationale for the Lesson

This lesson enables pupils to understand how new plants are produced and maintained, thereby promoting skills in agriculture, ensuring food supply, and encouraging self-reliance.

Prerequisite/Previous Knowledge

Pupils are already familiar with common farm crops and have seen seeds and plants growing on farms or in gardens. They also know that crops can grow from seeds and other plant parts.

Lesson Content/Board Summary

Crop Propagation and Cultural Practices

Meaning of Crop Propagation

Crop propagation is the process of producing new plants from parent plants to ensure continuous supply of food and other agricultural products. It helps farmers increase yield and sustain crop production.

The following are ways crop propagation is important:

It ensures continuous supply of crops.
It helps farmers maintain desired plant qualities.
It increases agricultural production.
It ensures survival of useful plant varieties.

Methods of Crop Propagation

Crop propagation is mainly grouped into two methods: sexual and asexual.

Sexual Propagation (By Seed)

Sexual propagation involves planting seeds that are formed after fertilization in plants. The seeds germinate to produce new plants.

The following are characteristics of sexual propagation:

It uses seeds of crops such as maize, rice, beans and groundnut.
It introduces variation among plants.
It is simple, cheap and widely practiced.
It allows for easy storage and transportation of seeds.

Asexual Propagation (By Vegetative Organs)

Asexual propagation uses parts of the vegetative organs of plants like stem, root, leaf, or bud to grow new plants without seeds. The new plant produced is identical to the parent plant.

The following are examples of vegetative organs used in asexual propagation:

Stem cutting – e.g., cassava and sugarcane.
Root cutting – e.g., sweet potato and yam.
Leaf cutting – e.g., cocoyam and bryophyllum.
Budding and grafting – e.g., citrus, mango, cocoa.
Suckers and rhizomes – e.g., banana, ginger.

Teaching Methods/Instructional Techniques:

Discussion, Lecture, Explanation, Demonstration, Group Work, Question and Answer, Use of Visual Aids

Instructional Procedures

To deliver this lesson, the teacher will adopt the following steps:

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: Teacher asks pupils how farmers multiply crops like yam and cassava, and links responses to the day’s topic.
Pupils’ Activity: Pupils respond with ideas and experiences from home or farm.
Learning Point: Pupils become interested and prepared to learn about crop propagation.

Step 2: Meaning of Crop Propagation

Time: 7 minutes
Teaching Skill: Explanation
Teacher’s Activity: Teacher defines crop propagation and explains its importance in agriculture.
Pupils’ Activity: Pupils listen, take notes, and answer questions.
Learning Point: Pupils understand the meaning and importance of crop propagation.

Step 3: Sexual Propagation (By Seed)

Time: 10 minutes
Teaching Skill: Demonstration
Teacher’s Activity: Teacher shows samples of seeds and explains how they are used for propagation.
Pupils’ Activity: Pupils observe, handle seeds, and note examples.
Learning Point: Pupils learn crops propagated through seeds and their advantages.

Step 4: Asexual Propagation (By Vegetative Organs)

Time: 10 minutes
Teaching Skill: Demonstration
Teacher’s Activity: Teacher shows cuttings of cassava, yam and cocoyam, and explains methods like grafting and budding.
Pupils’ Activity: Pupils observe and discuss examples.
Learning Point: Pupils identify crops propagated asexually and the plant parts used.

Step 5: Note-Taking

Time: 5 minutes
Teaching Skill: Reinforcement
Teacher’s Activity: Teacher dictates or writes the board summary for pupils to copy.
Pupils’ Activity: Pupils write notes in their books.
Learning Point: Pupils have accurate notes for future study.

Step 6: Evaluation/Review

Time: 5 minutes
Teaching Skill: Questioning
Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

What is crop propagation?
Mention two examples of crops propagated by seed.
List three plant parts used in asexual propagation.
State two advantages of sexual propagation.
Pupils’ Activity: Pupils respond to questions orally.
Learning Point: Pupils recall and demonstrate understanding of the lesson.

Step 7: Conclusion

Time: 3 minutes
Teaching Skill: Reinforcement
Teacher’s Activity: Teacher summarizes the lesson, emphasizes the importance of crop propagation, and encourages pupils to practice on their farms or gardens.
Pupils’ Activity: Pupils listen attentively and ask questions where necessary.
Learning Point: Pupils appreciate the value of crop propagation in agriculture.

Lesson Keywords

Propagation – the process of producing new plants
Sexual propagation – producing plants from seeds
Asexual propagation – producing plants from vegetative parts
Cutting – using stem, root or leaf to grow a new plant
Grafting – joining parts of two plants to grow as one

Differentiation

Teacher provides charts and live samples for better understanding, supports weaker learners with simple explanations, and challenges advanced learners with practical demonstrations.

Note for teachers using this lesson plan

Ensure pupils handle live samples during demonstration to make learning practical. Emphasize safety when using tools like hoes or knives. Relate the lesson to local crops familiar to pupils.
