CONTENTS OF THE LESSON

LESSON FOCUS – CLASSIFICATION OF CROPS

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

1. FORMS  – MONOCOTYLEDONOUS AND DICOTYLEDONOUS 

Monocotyledonous is a plant with the seed having only one cotyledon.

Examples of Monocotyledonous – maize, guinea corn, ginger, banana, wheat, palm, onion, garlic, etc.

 

Dicotyledonous is a plant with the seed having only one cotyledon.

2. LIFE SPAN – ANNUAL, BIENNIAL AND PERENNIAL CROPS 

Annual Crops 

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

 

BIENNIAL CROPS 

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