Rubber

Water

Rain falls about 8 irrigations (5 cm each) short in a normal year, so it's risky without water.

Needs about 1,170 mm of water here in its growing months. Rain gives about 800 mm it can use in a normal year, and 660 mm in a dry year.

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

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