The Winter Turf, because of its hardiness, is the most dependable 
variety for the vicinity of Washington, D. C. Its late maturity and 
its tendency to lodge, however, make it rather less desirable than the 
Culberson, Bicknell, and Red Rustproof. It matures at about the 
same time as wheat, while the other varieties may be harvested 
before the wheat crop is ripe. Where winter wheat is grown on the 
same farm, the earlier varieties are to be preferred. As they are less 
hardv, they must be sown earlier than is necessary for the Winter 
Turf~ 
EXPERIMENTS WITH WINTER BARLEY. 
Varietal tests of winter barley have been conducted at College 
Park since 1907 and at Arlington Farm since 1908. The tests at the 
former place have included 12 varieties, of which only four have been 
continued for the entire seven years (1908 to 1914). At Arlington 
Farm 56 varieties and strains have been grown from one to six years, 
most of them for short periods only. 
The dates of seeding at College Park during the past seven years 
were as follows: October 17, 1907; October 9, 1908; September 29, 
1909; September 21, 1910; September 20, 1911; October 1, 1912; and 
October 4, 1913, the average date being about October 2. The dates 
of seeding at Arlington Farm were September 29, 1908; September 
21, 1909; September 15, 1910; September 10, 1911; September 16, 
1912; and October 6, 1913, the average being about September 21, or 
11 days earlier than for College Park. Experience has shown that 
the date of seeding this crop at Arlington Farm has been too early in 
most years for the best results. On the other hand, the crop occa- 
sionally has been sown too late at College Park. While no definite 
rule can be formulated, it is believed that sowing between September 
25 and October 5 will give the best results under average conditions.
