Mustard Types, Seed Sources, & Acreage Estimates

Mustard Types:

There are two types of mustard being used in the Columbia Basin: white mustard (Sinapis alba, also called Brassica hirta or yellow mustard), and oriental mustard (Brassica juncea, also called Indian or brown mustard).  Commercial varieties are used to produce table mustard, oil, and spices.

The mustards being used for green manures should not be confused with weedy “mustards.”  Seed testing has shown that the mustard varieties being used for green manures do not have hard or dormant seed.  When planted in August, they have not been seen to set viable seed.  The table below shows the different types of mustards.

The weedy mustards are not all mustards but are all from the Brassica family.  Black mustard has been cultivated but has weedy characteristics.
