Here are clear notes for Module Two: Crop Production (commonly taught in Agriculture/TVET courses):
MODULE TWO: CROP PRODUCTION
1. Definition of Crop Production
Crop production is the science and practice of growing crops for food, fiber, fodder, and income.
2. Importance of Crop Production
Provides food for humans and animals
Source of income to farmers
Supplies raw materials for industries
Creates employment
Contributes to national economy
3. Classification of Crops
a) Based on Life Cycle
Annual crops – complete life cycle in one season (e.g. maize, beans)
Biennial crops – take two seasons (e.g. carrots, onions)
Perennial crops – live for many years (e.g. coffee, tea, bananas)
b) Based on Use
Food crops (maize, rice)
Cash crops (coffee, tea, sugarcane)
Fodder crops (napier grass)
Industrial crops (cotton, sisal)
4. Factors Affecting Crop Production
a) Climatic Factors
Rainfall
Temperature
Wind
Light
b) Soil Factors
Soil fertility
Soil texture and structure
Soil pH
c) Topography
Slope of land
Altitude
d) Biotic Factors
Pests
Diseases
Weeds
5. Land Preparation
Steps involved:
Clearing vegetation
Primary cultivation (ploughing)
Secondary cultivation (harrowing)
Levelling
Importance:
