been cut as early as August 10 with a very slightly smaller yield. The second growth on these two plats was over :'> feet high when killed by frost on November 4. The remaining 8 plats were harvested for seed on September 20 and yielded an average of 23 pound.- each, or 460 pounds per acre. Practically no seed was lost by shattering. The second growth in these plats was about 1 foot high when killed by frost on November 4. A late seeding was made on August 7 in rows, and this was 48 inches high and fully headed when killed by frost on November 4.

There can be no doubt that by seeding not later than June 1 two full cuttings of Sudan grass for hay can be obtained each season in J_ f.J :Im&m ifh jr » STHm "THtmI Sfti ©SfsJ S '-.KfeflSp MAIj kSiviSs'SAHfl ill Pig. 4.—Sudan grass at Arlington Farm.

Mixtures of Sudan grass with cowpeas and with soy beans were also tested (fig. 5). A one-tenth acre plat was broadcasted on June 11 with 3 pounds of Early Black cowpeas and 2 pounds of Sudan grass. This was cut for hay on September 6 when the Sudan grass was in bloom and the first pods of the cowpeas were fully grown. The grass was 6 to 8 feet high and the cowpea vines were of about an equal length. The plat yielded 9-2.") pounds of cured hay. about one-I (Mr. 125]
