SUDAN GRASS. 13 



was harvested for seed October 23, yielding ouly S i)ouuds. The total yield 

 of seed from the one-fifth acre plat was 05 pounds, or at the rate of 325 pounds 

 per acre. Seed tested 19 pounds per bushel, which gave the equivalent of 17+ 

 bushels per acre. 



A test at Dalhart, Tex., gave very promising results, thus reported 

 by Mr. ^Y. D. Griggs: 



Two one-tenth acre plats of Sudan grass, one broadcast and one in rows, were 

 seeded May 2, 1912 (tig. 1). The plat in rows failed to give a good stand and 

 it was reseeded May 21. It was intended that these plats be harvested for 

 hay, but owing to the local demand for seed among farmers it was decided to 

 let the grass mature and harvest it for seed. Both plats were harvested 

 September 7 and gave a total yield as follows: Broadcast. 545 pounds; in 

 rows. 552 pounds of hay per plat. The former yielded 40 i)ounds of seed; the 

 latter, 54 pounds. It is estimated that 25 i>er cent of the seed was lost In 

 harvesting. 



CALIFORNIA. 



The following is a report on a trial at the Plant Introduction Field 

 Station, Chico, Cal., by Mr. Roland McKee : 



Two rows of Sudan grass, one 75 feet long and the other 150 feet long, were 

 grown at Chico in 1912. It was grown on good loam soil and given Irrigation. 

 A fine growth was made, and without question this is the most jiromising grass 

 for growing imder irrigation in the Sacramento Valley that has yet been tried. 

 The number of cuttings of hay that it is possible to secure was not determined, 

 as with both the plantings a seed crop was allowed to mature, but it seems 

 probable that three good cuttings of hay can be made. One of the plantings 

 was allowed to produce a seed crop from the first growth. This was harvested 

 late, but still a good hay crop was produced after that date. The other plant- 

 ing was cut for hay shortly after it came into bloom. A good crop of hay was 

 secured and after that date a seed crop was matured. 



The following data give some idea of the growth of this crop: 



May 2 Itow 75 feet long; sown. 



July 9 In full bloom and 48 to 72 inches high. 



July 15 — Cut for hay. 



August 29 Second growth GO to 90 inches high, 



KQveniber 1 A good crop of seed was ripe. 



May 13 Row 150 feet long; sown. 



July 9 In first bloom and 30 to 40 inches high. 



August 20 First seed rljie. 



August 28 70 to 80 inches high. 



September 14_^ Cut for seed; 18 pounds secured. Yield about 40 

 liushels per acre figured on b;!sis of 4-foot rows 

 and 30 i)ounds of seed per bushel. 



November 3 Second growth 3 to 4 feet high. 



SOUTH DAKOTA. 



A small test made in 1912 at Brookings, S. Dak., is thus reported 

 by Mr. Samuel Garver: 



Three rows, 36 inches apart, each 8 rods long, were planted Aiiril 30. The 

 grass grew very slowly during the cool spring, being only 3 or 4 inches high 

 on June 10, and was not injured meantime by three or four frosts. At this 

 time warm weather began and the grass grew rapidly, maturing its seed
