Arid regions face water scarcity, high evaporation, and poor soil. Strategic crop selection and irrigation minimize input costs while maximizing yields.
Arid-Adapted Crops
| Crop | Water Need | Yield | Return |
|---|---|---|---|
| Chickpea | 250–350 mm | 1–2 t/ha | 150–300k |
| Lentil | 250–400 mm | 1–1.5 t/ha | 150–300k |
| Barley (rainfed) | 200–350 mm | 2–3 t/ha | 60–90k |
| Onion (drip) | 400–500 mm | 20–30 t/ha | 800–1.5M |
| Carrot (drip) | 350–450 mm | 25–35 t/ha | 750–1.4M |
Water Conservation
- Drip irrigation: 50–60% water savings vs. flood/sprinkler irrigation
- Mulch: Reduce evaporation 30–50%; improve soil moisture retention
- Raised beds: Concentrate water; prevent salinization
- Soil amendments: Add compost/manure (improves water-holding capacity 10–20%)
Irrigation Schedule
Drip system: 2–4 hours/day, every other day (vs. 6–8 hours every day for flood)
Arid Intercropping
Legume + cereal: Chickpea + barley uses water efficiently; chickpea nitrogen supports barley
