Brinjal, also known as eggplant, is a warm-season crop that is grown in a variety of soil types, but it prefers well-drained loamy soils. It needs a warm climate and rainfall of about 400-600 mm.

India is the world's largest producer of brinjal, accounting for about 30% of the world's production. The major brinjal-growing states in India are Maharashtra, West Bengal, Andhra Pradesh, Karnataka, Gujarat, Tamil Nadu, Uttar Pradesh, Madhya Pradesh, Bihar, and Odisha.

The cultivation of brinjal involves several steps, including land preparation, sowing, irrigation, weeding, pest control, and harvesting. The crop is harvested by hand, and the brinjals are then eaten fresh, cooked, or pickled. Brinjals are a versatile crop that is used in a variety of dishes. It is also a good source of dietary fiber, potassium, and vitamin C.
