No figures for your district: its government crop records list no area or yield for this crop.
Only with irrigation: rain gives too little of its water to count on
- Doesn't suit: Too dry without irrigation
- Doesn't suit: Winters are too warm for it to fruit
- Needs care: Soil 7/10
Why, and how to make it work Hide details
Water
Too dry to grow on rain alone. It would need irrigation.
Needs about 1,480 mm of water here in its growing months. Rain gives about 490 mm it can use in a normal year, and 360 mm in a dry year.
Temperature
Grows best at 15–30 °C on average, and survives 7–40 °C.

How the soil score worksMoney
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.
