TEST FOR GRASS, CLOVER, OR ALFALFA SEED 91 



Which sample gives the largest amount of pure seed for 

 the money invested? Can you identify any of the weed 

 seeds? Taking into consideration the quality and the weed 

 seeds, which sample should be purchased? 



Discussion: Low-priced seeds are usually the most 

 expensive that can be purchased, because they frequently 

 show low vitality and may be seriously contaminated by the 

 presence of troublesome weed seed.

Before seed is purchased for the farm a small sample 

 should be secured, tested for vitality, and examined for 

 the weed seeds. In many States the Agricultural Experi- 

 ment Station will test samples free of charge for the farmers 

 of the State. 



Weed seeds may be sent to the State Station or to the 

 United States Department of Agriculture, Washington, 

 D. C, for identification.
