(5) The spring cereal varieties yielded less than the winter varieties, even though a 

 better stand was obtained. 



In the increase rows a decided improvement in the yielding power 

 of the cereal varieties was evident, probably due to the use of pure 

 strains. 



Tests with minor cereals have been limited. Some work has been 

 done with grain sorghums, broom corn, millets, and prosos, but the 

 results obtained have given little promise that these crops are adapted 

 to the dry lands of the intermountain region. 



In the test of size of seed with both spring and winter varieties, the 

 large seed was best in number of heads produced per plant and in yield 

 per row. No great difference was observed among the different sizes 

 of seed, in the percentage of survival, plants maturing, or length of 

 heads produced. 



In the test of different seed treatments for smut, the following points 

 were observed : 



(1) The effect of the time of seeding on bunt depended largely on the season. 



(2) The best copper-sulphate treatment was 1 pound of copper sulphate to 10 gallons 

 of water, the seed soaked 10 minutes and dried. 



(3) The best formalin treatment was 2.5 parts of formalin to 1,000 parts of water, the 

 seed soaked 10 minutes and kept moist 2 hours.
