Rubber

Water

Too dry to grow on rain alone. It would need irrigation.

Needs about 1,890 mm of water here in its growing months. Rain gives about 120 mm it can use in a normal year, and 80 mm in a dry year.

Temperature

Grows best at 24–33 °C on average, and survives 10–45 °C.

Not in the score: nitrogen, sulphur and boron.

• Soil here is often too alkaline for it.

Money

A new planting gives its first real harvest after about 7 years. The money here is for plants already bearing.

No yield records for this crop yet.

Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.
