Only one cutting was secured from this planting. Both plats were planted on March 31—somewhat later than is necessary. The first cutting of the irrigated plat was on July 31 and gave a yield at the rate of tons per acre and a seed yield of at least 5er acre. The second cutting was made on October 10 and gave a yield of tons i»er acre, making a total for the season of tons per acre. At least three cuttings would have been secured had it been seeded earlier and the first cutting not allowed to seed, which would have increased the yield materially. In 1912 we put in a planting of Sudan grass March ;», without irrigation, and the yield from two cuttings was (5 tons per acre. Sorghum planted under the same conditions gave a yield of Fig. 6.—Rows of Tunis grass at Arlington Farm, Virginia, l'J12. Note the very uiucli thinner appearance of this grass as compared with the Sudan grass in figure :!. At College Station, Tex., a-test was made in 1912 by Mr. A. B. Conner, who sent in the following report: Planted May 15 on one-fifth acre plat in rows 3 feet apart. Germination was fairly good, but stand not as uniform as desirable. Grass made very vigorous growth up to July 1. On July 7 was just coming into full boot. On July 15 it was in full head at a height of 7 feet and presented a very vigorous apiiear- ance. On August S the plat averaged 7 feet in height, and on account of tlie irregular stand each plant had put out a number of culms. Some were noted with as many as 40 to 50. Plants were very leafy to the top, showing superi- ority in this respect to Johnson grass. Harvested August 14 for seed and gave a yield of 57 p
