Farming System for Low Rainfall Areas
The farming system adopted in an area with less than 50 cm annual rainfall is:
- Irrigated farming
- Extensive farming
- Dry farming — Correct Answer
- Intensive farming
Explanation:
Correct Answer: Dry farming
Dry farming is adopted in areas that receive less than 50 cm of annual rainfall. It relies on moisture conservation techniques rather than irrigation.
Examples of Dry Farming
- Agro-forestry (Arable crop + Forestry trees for timber, fuel or fodder)
- Silviculture (Silvi = forest + Culture = growing; growing forest trees for timber or fuel)
Comparison of Farming Types by Water Use
- Dry farming: <50 cm annual rainfall; no irrigation; moisture conservation.
- Irrigated/Garden/Wetland farming: Requires regular water supply. Example: Sericulture.
- Extensive farming: Large area used to increase output. Example: Deep litter poultry system.
- Intensive farming: More capital on small area. Example: Multi-tier cage system.
Memory Tip
Dry < 50 cm → Dry farming. Think of deserts and dryland crops like millets and sorghum grown without irrigation.
