Walnut

Water

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

Needs about 1,620 mm of water here in its growing months. Rain gives about 710 mm it can use in a normal year, and 570 mm in a dry year.

Temperature

Grows best at 15–30 °C on average, and survives 7–40 °C.

It needs a cold winter to flower: a coldest month averaging 12 °C or less. Here the coldest month averages 18 °C.

Soil

Soil for Walnut: 8 out of 10 (good).

• The pH here suits it.
• Many fields here are short of zinc, which it needs a lot.
• Most fields here are short of nitrogen.

Likes pH 5.5–6.5.

Money

Yield: about 14 quintals an acre, the typical figure across India (no figures for your state).

A new planting gives its first real harvest after about 6 years. The money here is for plants already bearing.

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