Irrigation by crop

Irrigation for guava

Trees 5-6 m apart on the conventional spacing, much closer under high-density planting. A lateral down each row with drippers at every tree.

Suits it best

Drip irrigation

Usual row spacing

5–6 m

Water need

2.5–6 mm/day

Water need is the crop’s daily use at full cover over the whole year, at weather stations across Telangana and Andhra Pradesh — the spread is the season and the place.

Why drip irrigation

Trees 5-6 m apart: a lateral down each row with drippers at every tree, the layout Telangana’s scheme uses for guava.

A lateral down each tree row, rows 5–6 m apart, with 4 drippers at every tree.

What actually changes the answer

  • At 6 × 6 m an acre holds about 110 trees; at a high-density 3 × 1.5 m, about 900 — and the dripper count scales with them.
  • Four drippers a tree on one lateral suits a young orchard. The state scheme moves orchards over eight years old to two laterals and eight drippers.
  • Many growers hold back water for a few weeks to time the flowering. Drip makes that easy to control, and easy to restart.

Spacings and layouts on this page are published package-of-practice and state-scheme figures; water need is FAO-56’s crop-coefficient method on published Telangana and Andhra Pradesh weather records. Neither is a design for your field — soil, slope, water source and pump all move them. Send us your crop, acres and pump details and we’ll confirm the sizing before you commit.
