In an adjacent one-tenth acre plat Johnson grass and cowpeas were seeded at the same rate; that is, 2 pounds of Johnson grass and 3 pounds of Early Black cowpeas in place of Sudan grass (fig. 5).

About one-fourth of the mixture was soy beans, which twined about the grass to a height of 4 to 6 feet. When. Fig. 5.—riats at Arlington Farm, Virginia, sliowing mixtures of Sudan grass and cowpeas (rigbt) and Johnson grass and cowpeas (left). cut on September 6 the Sudan grass was in bloom and the soy-bean pods w^ere about half grown. This mixture cured more readily than the cowpea mixture and was superior in physical quality. The yield was 888 pounds of cured hay, or at the rate of : tons per acre.

At the San Antonio (Tex.) Field Station Mr. S. H. Hastings tested Sudan grass in 1911 and 1912 and reported as follows: From the growth of the plat tested in 1911 this apijears to be the most prom- ising grass that has been grown at the experiment farm.
