SMALL GRAINS 



A series of small grain plantings was made in the fall of 1916 

 at different dates from August 15th until the middle of November. 

 In these plots Crimean wheat, Black winter emmer, fall rye, and 

 Tennessee winter barley were used. The results from the earlier 

 plantings of wheat and rye were very promising, while the later 

 plantings did not do so well. The barley winter killed completely 

 and yields from the emmer were small. Rye sown on the earlier 

 dates in rows seven inches apart yielded 3200 pounds of hay per

acre. In the plot where the rows were twenty-one mches apart, 

 the yield was slightly less than 2000 pounds. Similar plots which 

 were allowed to mature grain yielded fourteen, eleven, and nine 

 bushels per acre, respectively, and in the later plantings the grain 

 yields were as low as five and one-half bushels per acre. Wheat 

 yields consistently ran about two bushels per acre more than rye. 

 In no case was the grain of the highest quality. 



SUDAN GRASS 



About eight acres were planted to Sudan grass in May of the 

 current year. Approximately one-half of this was cut for hay and 

 the two cuttings yielded about two tons per acre in addition to a 

 slight amount of pasturage. The remaining half, which was alknved
