Cultural Practices in Agriculture
Cultural practices/methods are agricultural practices used to enhance crop production by improving the quality and quantity of crop produce, preventing weed, pest & disease problems without the use of chemical substances.
In cultural practices we try to avoid the use or the use of chemicals in crop growth
excessive reduce
Farmer JimUses no chemicals and uses cultural practices to grow his crops
Farmer LarryUses a large quantity of chemicals and no cultural practices to grow his crops
Observe the two(2) scenarios
Cultural Practices in Agriculture
Moulding
Mulching
Staking
Weeding
Pruning
Fertilizing
(organic manure/fertilizer)
Irrigation
Moulding
Moulding - helps to increase root development
Moulding-this is when soil is scraped up and heaped around the base of a plant to form a small mound using a hoe or hand spade
- Increase soil aeration
- Prevents soil erosion
Mulching
Mulching – this is the placing of dry grass, sawdust, wood shaving or plastic to keep soil moist and prevent soil erosion.
It is usually done in the dry season
Advantages of mulching-
Conserves water in the dry season
Adds organic matter to the soil
Improves the structure of the soil
StakingStaking is an agricultural practice which involves a stake (wood) being placed into the soil, parallel to the plant. This helps to support the plant and keep the plant and fruit off the ground
Advantages of staking
reduces losses from fruit rots when fruit touch the soil
plants are easier to spray for insect and disease control
easier to harvest than those sprawling on the ground

Disadvantages of weeds
Compete with the plant for sunlight, water and nutrients
Encourages pest which attacks crops
Encourages diseases organisms to infest plants
Compete with the crop for space to grow
Methods of weed control
Manual- hand pulling, hoe Chemical- weedicides (Gramozone, Round up) Mechanical - “waka”,
