Water

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

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

Soil

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

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

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.
