This season's sowing time (June–July) is over.
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
- Needs care: Very hot in June
- 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 1,300 mm of water here in its growing months. Rain gives about 220 mm it can use in a normal year, and 180 mm in a dry year.
Temperature
Grows best at 25–30 °C on average, and survives 10–35 °C.
Here, in its growing months (day / night):
- Jun 40 °C / 27 °C (outside its best range)
- Jul 37 °C / 27 °C (outside its best range)
- Aug 35 °C / 27 °C (outside its best range)
- Sep 34 °C / 24 °C
- Oct 33 °C / 18 °C
- Nov 28 °C / 11 °C (outside its best range)
Months in orange are outside its best range.
Days in June get hotter than it likes. Time sowing so it flowers before then.

How the soil score worksMoney
Yield: about 15 quintals an acre, the typical figure across India (no figures for your state).
Rain gives it too little of the water it needs, so there's no income figure on rain alone: grow it only with irrigation.

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 potassium Your soil is likely short of potassium.
Add about a quarter more potash (MOP) than the usual dose.
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.
Ask your Krishi Vigyan Kendra what to add for this crop.
-
Short of manganese Your soil is likely short of manganese.
Spray manganese sulphate, 5 g per litre of water, on the young crop.
Ask your Krishi Vigyan Kendra what to add for this crop.
