TOPIC: Classification of Crops
CONTENT:
- Classification of crops based on lifecycle
- Classification of crops based on morphology
SUB TOPIC 1:Â Classification of crops based on life cycle
Lifecycle means a period from germination to harvesting. Based on these, crops are classified into four groups and these are:
- ANNUAL CROPS: These are crops that complete their life cycle within one year eg rice, cowpea, millet, groundnut, maize etc
- BIENNIAL CROPS: These are crops which complete their life cycle within two years eg carrot, pineapple, ginger etc
- PERENNIAL CROPS: These are crops which complete their life cycle in more than two years eg mango, rubber, citrus, oil palm etc
- EPHEMERAL CROPS: These are crops that complete their life cycle within a very short time (probably within three months) eg amaranthus, tomatoes, spinach, celosia etc
EVALUATION
- Explain what you understand by term life cycle
- State the classes of crops based on lifecycle with two examples each.
SUB TOPIC 2: Classification of crops based on Morphology
Based on their structure, crops can be classified into two groups as follows
- Monocotyledonous Crops: These are crops that have only one seed leaf (cotyledon). Examples are rice, maize, oil palm, coconut, wheat, barley, sorghum etc
- Dicotyledonous Crops: These are crops that have two seed leaves(cotyledons). Examples are cocoa, cowpea, groundnut, mango, citrus, soybeans etc
