F. Yield Average yield are in the 800 to 1200 pound range, with a value of 9 to 13 cents per pound. I have seen yellow mustard reach as high as 35 cents per pound, so definately is a finicky specialty crop. Current value is around 10 cents per pound. G. Storage Mustard seed can be stored safely when the moisture content reaches 9 percent or less. Care should be taken to avoid cracking the seed while moving the crop in and out of storage.
Cracked seed ends up as dockage and a loss to the producer.
Tight bins and truck boxes free of cracks or holes, are essential for transfer and storage of mustard. In Northeast Montana, that would include volunteer cereals, wild oats and green foxtail. Broadleaf weed problems include kochia, Russian thistle and wild buckwheat. Mustard crops are poor competitors with weeds in the early seedling stage and weeds can greatly reduce mustard yields. Weed seeds, which are difficult to remove, can cause high losses during seed cleaning and lower market grades.
