EXERCISE 35 

 A STUDY OF SORGHUM SEED 



Object. To study the purity and worth of sorghum seed. 



Explanation. There are two general classes of sorghum, 

 saccharine and nonsaccharine. Saccharine sorghum is 

 used extensively for forage and for the production of sorghum 

 sirup. The seed of saccharine sorghum has a bitter taste 

 and is not generally used as feed for live stock. However, it 

 has a commercial value as it is used extensively for planting. 

 The nonsaccharine sorghums are used extensively for forage 

 and their seed is used for feed. 



Sorghum seed is more easily injured in handling than most 

 of the other small grain cereals. The 'kernels crack easily 

 in threshing, and their vitality is often reduced by improper 

 storing. Sorghum seed of different varieties is often some- 

 what mixed. 



Equipment. 1. Four ten to twelve pound samples of 

 sorghum seed representing the different types of sorghum. 



2. A weight-per-bushel tester. 



3. A balance weighing to one half gram. 



4. Type samples of sorghum seed. 



Directions. Weigh out twenty grams of sorghum seed 

 from one of the samples and make a detailed study of it.
