Start with what you grow

Wide, well-spaced rows and a long season — inline drip on every row pays back fastest here.

Row spacing

0.9–1.2 m

Water need

4–6 mm/day

High-value crop, sensitive to water stress at flowering. Drip keeps the root zone steady.

Row spacing

0.6–0.9 m

Water need

3–5 mm/day

Sown close and almost broadcast. Rain pipe wets the whole strip; drip on 30cm rows is rarely worth it.

Row spacing

0.3–0.45 m

Water need

3–5 mm/day

Grown in standing water. Neither drip nor sprayline is the standard method — this is a channel and conveyance job.

Row spacing

0.2–0.25 m

Water need

6–10 mm/day

Short cycles and frequent picking — drip waters the row without wetting the paths.

Row spacing

0.6–0.9 m

Water need

3–5 mm/day

A long-duration crop with heavy total demand; drip cuts the pumping bill over 12 months.

Row spacing

0.9–1.2 m

Water need

4–7 mm/day

Heavy, near-continuous water demand over a 10-12 month crop, on rows close enough that flooding wastes most of it. Drip is the standard here.

Row spacing

1.8–2.1 m

Water need

5–8 mm/day

Widely spaced bushes on a multi-year planting — one lateral per row waters the root zone directly and keeps the alleys dry for picking.

Row spacing

3–4.5 m

Water need

3–5 mm/day

Widely spaced trees — one lateral per row of trees, so pipe needed per acre is low.

Row spacing

3–5 m

Water need

3–5 mm/day
