YELLOW MUSTARD

These mustard seeds are known in Hindi, Urdu, and Punjabi as sarson (Indian colza, Brassica rapa subsp. trilocularis, syn. Brassica campestris var. sarson),in Bengali as shorshe. These are used as a spice in Pakistan, Northern India, Nepal, and Bangladesh. The seeds are usually roasted until they pop. 
Mustard seeds generally take eight to ten days to germinate if placed under the proper conditions, which include a cold atmosphere and relatively moist soil. Mature mustard plants grow into shrubs.

Mustard grows well in temperate regions. Major producers of mustard seeds include India, Pakistan, Canada, Nepal, Hungary, Great Britain and the United States. Brown and black mustard seeds return higher yields than their yellow counterparts.
