Rubber

Water

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

Needs about 1,470 mm of water here in its growing months. Rain gives about 800 mm it can use in a normal year, and 700 mm in a dry year.

Temperature

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

Here, in its growing months (day / night):

• Jun 36 °C / 25 °C
• Jul 32 °C / 24 °C
• Aug 31 °C / 24 °C
• Sep 31 °C / 22 °C

Soil

Soil for Rubber: 7 out of 10 (okay).

Not in the score: nitrogen.

• Soil here is often too alkaline for it.
• Many fields here are short of potassium, which it needs a lot.
• Most fields here are short of organic carbon.

Likes pH 4.5–6.0.

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.
