Why, and how to make it work Hide details
Water
Rain falls about 3 irrigations (5 cm each) short in a normal year, so it's risky without water.
Needs about 530 mm of water here in its growing months. Rain gives about 430 mm it can use in a normal year, and 280 mm in a dry year.
Temperature
Grows best at 20–30 °C on average, and survives 15–39 °C.
Here, in its growing months (day / night):
- Jul 33 °C / 26 °C
- Aug 33 °C / 26 °C
- Sep 33 °C / 25 °C
- Oct 32 °C / 21 °C
- Nov 29 °C / 14 °C
- Dec 24 °C / 9 °C (outside its best range)

How the soil score worksMoney
Yield: about 7.5 quintals an acre, the typical figure across India (no figures for your state).
On rain alone it gets about 81% of the water it needs, so the money here is worked at 81% of this yield.
Mandi price at last season's harvest (December 2025–January 2026): about ₹6,218 a quintal across India's mandis.
This week: about ₹7,560 a quintal, the middle of 9 mandis across India (latest 13 Nov). At that price an acre would leave about ₹22,000 a season after typical costs.

How to make it work
-
Short of nitrogen Your soil is likely short of nitrogen.
Add about a quarter more urea than the usual dose, in two or three splits. A pulse crop in rotation also adds nitrogen.
Ask your Krishi Vigyan Kendra what to add for this crop.
-
Short of organic carbon Your soil is likely short of organic carbon.
Add 4 tonnes of compost or farmyard manure per acre before sowing, and plough crop leftovers back in instead of burning them.
