(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 
perrow. 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.
