Walnut

Water

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

Needs about 1,520 mm of water here in its growing months. Rain gives about 210 mm it can use in a normal year, and 110 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 41 °C / 28 °C (outside its best range)
• Jul 37 °C / 27 °C (outside its best range)
• Aug 35 °C / 26 °C (outside its best range)

• Apr 38 °C / 20 °C
• May 42 °C / 26 °C (outside its best range)
• Jun 41 °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 13 °C.

Soil

Soil for Walnut: 8 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.
• Most fields here are short of iron.

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.
