CEKEAL EXPERIMENTS IN MARYLAND AND VIRGINIA. 49 
bushels of 60 pounds each. This is equivalent to about 26 bushels 
of hulled barley. The Hansee matures about three days earlier than 
the Tennessee Winter. 
EXPERIMENTS WITH SPRING-SOWN GRAINS. 
Several attempts have been made to grow spring wheat, oats, and 
barley at Arlington Farm, but with little or no success. Of the three, 
the best yields have been obtained from spring oats. The yields, 
however, were much lower than from fall-sown oats, and the crop is 
much more uncertain. No profitable yields of spring barley and 
spring wheat have been produced in these experiments. Each time 
that spring wheat has been grown rust has practically destroyed the 
crop. 
A few varieties of buckwheat have been tested, but with very un- 
satisfactory results. This crop is not well adapted to the warmer 
portions of the humid area. The highest yield obtained with buck- 
wheat at Arlington Farm was about 10 bushels per acre. 
The prosos (broom-corn millets) also have been tested as a grain 
crop, but without success. Of 10 varieties grown at Arlington Farm 
in 1911 and 1912, not one produced anything approaching a satis- 
factory yield. Proso is not of value as a grain crop in the humid 
portions of the United States. 
The few tests which have been made of grain sorghum indicate 
that this crop does fairly well at Arlington Farm. However, it is 
not a profitable crop where corn can be grown successfully, and there 
is no reason to grow any of the various forms in this locality. 
SUMMARY. 
Experiments with cereals have been conducted since 1907 at Col- 
lege Park, Md. (in cooperation with the Maryland Agricultural 
Experiment Station), and at Arlington Farm, Va. The results of 
varietal tests of the different winter cereals are reported in this 
bulletin. 
The average annual rainfall for the ten 12-month periods from 
July 1, 1904, to June 30, 1914, inclusive, at Washington, D. C, was 
42.33 inches. The average annual rainfall at College Park is about 
4 inches less than at Washington. 
The size of the plats on which the varietal tests were conducted 
was in most cases one-twentieth of an acre. 
The varietal tests at College Park have included 107 varieties and 
races of wheat, 5 of spelt, 3 of emmer, 13 of oats, and 12 of barley. 
At Arlington Farm the tests have included 43 varieties and races of 
winter wheat, 12 of rye, 4 of spelt, 2 of emmer, 19 of oats, and 56 of 
barley. Only winter varieties of the various cereals are adapted.
