Study Notes

Crop Propagation: Meaning and Methods

Crop propagation is the process of increasing the number of plants.
Two main types exist: sexual (seed) propagation and asexual (vegetative) propagation.

Sexual Propagation (Seed Propagation)

Uses seeds to multiply crops (e.g., maize, tomatoes, vegetables).
Advantages: The primary commercial method for field crops; plants grown from seed may live longer; important for developing new varieties; seedlings are easier and cheaper to raise.
Disadvantages: Slower fruit production; offspring may not be true to the parent plant; seed dormancy can prevent germination; growth, maturity, yield, and other characteristics may vary; some plants produce few seeds.

Asexual Propagation (Vegetative Propagation)

Uses plant parts (e.g., cassava, yam, ginger) to multiply crops.
To be completed by the student: List five advantages of asexual propagation.
