Irrigation by crop
Irrigation for chilli
A high-value crop that punishes water stress at flowering. Drip keeps the root zone steady instead of swinging between flooded and dry.
Suits it best
Drip irrigation
Usual row spacing
0.6–0.9 m
Water need
3–5 mm/day
Why drip irrigation
High-value crop, sensitive to water stress at flowering. Drip keeps the root zone steady.
What actually changes the answer
- Close rows (0.6-0.9 m) mean more lateral per acre than cotton — budget for it.
- Stress at flowering and fruit-set costs yield directly, which is why steady daily application beats a heavy weekly flood.
- Keeping the paths dry between rows makes picking easier and slows fungal spread in a wet season.
