Use. The seeds contain 23-47% oil (iodine number 92-119). After heating the oil has high taste qualities and is used in confectionery and baking industry for making pastry in the tin, margarine, soap and pharmaceutical industries.

Norma sowing to 9 kg / ha at sowing and the joint is 2 times higher in net. Cultivated forms contain the seeds of 30-38% oil. Yield of seeds 0.8-1.5 t / ha.
In India, black mustard species - Brassica nigra (L) Koch (left) - known as the paradise of Benares, is common in the states of Uttar Pradesh, Punjab, Tamil Nadu.
