Mustard seeds are the small roundseeds of variousmustard plants. The seeds are usually about1 to 2 millimetres (1⁄32 to3⁄32 in) in diameter and may be colored from yellowish white to black. They are an importantspice in many regional foods and may come from one of three different plants: black mustard (Brassica nigra), brown mustard (B. juncea), or white mustard (Sinapis alba).
Grinding and mixing the seeds withwater,vinegar or other liquids creates the yellowcondiment known asmustard.
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.
Yellow mustard has a plant maturity of 85 to 90 days; whereas, brown and oriental mustard have a plant maturity of 90 to 95 days. If the temperature conditions are conducive to growth, a mustard plant will begin to bud five weeks after the seedlings have appeared. The plant will reach full bloom 7 to 10 days later. Black, brown or oriental varieties of mustard tend to have higher yields compared to yellow mustard.[1][2] Seed yield is also related to the bloom period. In other words, the longer the bloom period, the greater the seed yield.[3]
Mustard grows well in temperate regions. Major producers of mustard seeds include India, Pakistan, Canada, Nepal, Hungary, Great Britain and the United States.
In Pakistan, rapeseed-mustard is the second most important source of oil, after cotton. It is cultivated over an area of 307,000 hectares (1190 sq. mi) with an annual production of 233,000 tonnes and contributes about 17% to the domestic production of edible oil.
Mustard seeds are a rich source of oil and protein. The seed has oil as high as 46–48%, and the whole seed meal has 43.6% protein.
In 2021, Nepal ranked the highest in mustard seed production, followed by Russia and Canada.[4] In 2023, India led the world production of mustard seeds with 12 million tons.[5]

In North America, mustard is produced as a specialty crop. The majority of production is found in the upper Midwest United States and Canada. In 2020, the total production of mustard in the United States was 81.8 million pounds (37.1 kt).[7]
Mustard seeds carryseed-borne pathogens which affectgermination rate, as any other seed.[8] Latifet al., 2006 isolateAlternaria,Aspergillus,Chaetomium,Curvularia,Fusarium,Penicillium, andRhizopus inBangladesh.[8]: 78

The mustard seed is frequently referenced in world literature, including in religious texts, as ametaphor for something small or insignificant.
In the Bible,Jesus tells theParable of the Mustard Seed referring to faith and the Kingdom of God. There, Jesus says, "The kingdom of heaven is like to a grain of mustard seed, which is the smallest of all seeds on earth. Yet when planted, it grows and becomes the largest of all garden plants, with such big branches that the birds can perch in its shade."[15]
There are references to mustard seeds in India from a story ofGautama Buddha in the fifth century BC. Gautama Buddha told the story of the grieving mother (Kisa Gotami) and the mustard seed. When a mother loses her only son, she takes his body to the Buddha to find a cure. The Buddha asks her to bring a handful of mustard seeds from a family that has never lost a child, husband, parent, or friend. When the mother is unable to find such a house in her village, she realizes death is common to all, and she cannot be selfish in her grief.[16][17]
Jewish texts compare the knowable universe to the size of a mustard seed to demonstrate the world's insignificance and to teach humility.[18]
The mustard seed is mentioned in theQuran: "And We place the scales of justice for the Day of Resurrection, so no soul will be treated unjustly at all. And if there is [even] the weight of a mustard seed, We will bring it forth. And sufficient are We as accountant (21:47)",[19] and according to theHadith,Muhammad said that he who has in his heart the weight of a mustard seed of pride would not enter Paradise.[20]
