EXERCISE 32 

 A STUDY OF BARLEY 



Object. To study samples of barley with reference to 

 their quality and commercial grade ; and to become familiar 

 with different classes and grades of barley. 



Explanation. A large amount of barley is used as 

 a grain feed for live stock on farms where it is produced. 

 Approximately one half of the barley produced is sold on 

 the commercial market, where it is finally used either for 

 brewing or feeding purposes. The value of barley depends 

 largely upon the quality of the grain. In determining quality 

 it is necessary to consider purity, soundness, color, texture, 

 size, and other conditions of the grain. The student should 

 become familiar with different classes and grades of barley. 



Equipment. 1. Four ten-pound samples of barley. 



2. A weight-per-bushel tester. 



3. A balance weighing to one half of one gram. 

 Directions. Weigh out twenty grams of barley from 



one of the samples, and make a detailed study of it. Use 

 the outline form "A Study of Barley" to record the results 

 of the examination. Compare the sample of barley under 

 observation with named type samples for identification. 

 Record type name in the column for that sample number 

 for classification.
