30 per cent. When grown under unfavorable conditions, 



the percentage of hull is relatively high, while favor- 



able conditions for 



growth produce 



short, plump grains, 



with a relatively low 



percentage of hull. 



The size, shape, and 



color of the grain 



vary with the con- 



ditions of growth, 



and with the vari- 



ety. The most com- 



mon colors are white 



and yellow, although 



quite a few varieties 



are black, gray, or 



red in color. The 



legal weight per 



bushel in most states 



is 32 pounds. How- 



ever, the weight per 



measured bushel 



varies with the va- 



riety, the season, and 



the time of cutting, 



and due to these 



factors, will some- 



times show a range 



of from 20 to 50 



pounds per bushel. 



" Clipped oats " is a market term employed to define oats
