• It requires a temperature range of 20-35 C with an annual rainfall of 1500 mm or more, under rainfed or irrigated conditions.
• Though it can be grown on different types of soils, it thrives best in well-drained sandy or clay loam soils with a pH range of 4.5-7.5 with good organic status.

Varieties

• A number of cultivars are available in the country and are known mostly by the name of locality where they are cultivated.
