WHEAT, OATS, RYE, AND BARLEY 



How to recognize the seeds of the small-grains. Tht 

 threshed grain of wheat, oats, rye, and 

 barley may be distinguished as fol- 

 lows : 



Oat kernels are wrapped tightly in 

 a long tough hull. Barley grains are 

 covered with a hull that has grown 

 to the kernel, forming an angular 

 grain. Wheat grains have no hull after 

 being threshed, and are short and 

 usually plump. Rye grains, like wheat 



grains, have no attached hull, but FlG - 8 5- PART OF A

How to recognize the young 

 plants. It is possible to distin- 

 guish between fields of these plants 

 when they are small. This can be 

 done by the width of the leaves, and 

 the erect or spreading growth. It 

 is sometimes puzzling to decide 

 whether a single young plant is 

 wheat, oats, rye, or barley. On the 

 leaves of young barley, wheat, and 

 rye plants there are tiny growths 

 like little horns, clasping the stem.. 

 These may be called "clasps." They
