BIOLOGY LESSON NOTE ON CROP PROPAGATION

Image
Topic: Crop Propagation Class: Senior Secondary School 2 (SS2) Subject: Biology Specific Objectives By the end of this lesson, students should be able to: Define crop propagation. Differentiate between sexual and asexual propagation. Identify and explain various methods of crop propagation. Highlight the advantages and disadvantages of each method. Recognize common examples of crops propagated using each method. Lesson Content 1. Meaning of Crop Propagation Crop propagation refers to the process by which plants reproduce or are reproduced to give rise to new plants. This can occur naturally or be carried out artificially by farmers or agricultural scientists. It is a vital practice in agriculture that ensures the continuous production of food and other plant-based resources. 2. Types of Crop Propagation Crop propagation is broadly categorized into two main types: Sexual Propagation (Seed Propagation) Asexual Propagation (Vegetative Propagation) 3. Sexual Propa...
