Walnut

Water

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

Needs about 1,610 mm of water here in its growing months. Rain gives about 600 mm it can use in a normal year, and 460 mm in a dry year.

Temperature

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

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

• Jun 40 °C / 28 °C (outside its best range)
• Jul 33 °C / 25 °C
• Aug 31 °C / 25 °C
• Sep 33 °C / 24 °C
• Oct 35 °C / 20 °C
• Nov 31 °C / 14 °C
• Dec 28 °C / 11 °C
• Jan 26 °C / 10 °C
• Feb 30 °C / 13 °C
• Mar 36 °C / 18 °C
• Apr 40 °C / 24 °C (outside its best range)
• May 43 °C / 28 °C (outside its best range)
• Jun 40 °C / 28 °C (outside its best range)

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: 9 out of 10 (good).

Not in the score: nitrogen and boron.

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

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.
