QUDA.N GRASS is grown tat hay. It was obtained in 1909 0 fnim the Suda» Govomment at Kheatum as the result of a s>sl,cmatii' March for a I01111 oC .lolinson gnus without rool stocks. No other plant iniportatinn ever gained such iirunedi-Bte and widespread (lopularil y in the United Slates.
Sudan BreH is strictly an annual without underground rootstorks. It grows to a height of .'I to 5 feet in drilled seedings and 6 to JÎ feet in cultivated rows. Drilled seedings are generally preferred for hay and the (iillivaled rows for seed production.
Sudan grass requires a warm dirnate for its best development and is of most \alue as an emergency hay crop, being superior to millet for this purpose in all except the northern third of the 1 nited Stales. In irrigated sections of the Southwest, Sudan grass yielda practically as much hay as alfalfa and is very useful in providing a variety of roughage for dairy cows.
The best time to cut Sudan grass for hay is when it is in full head, but the grass can be harvested somewhat earlier or later than this with DO material loss in feeding value.
Sudan grass is a good soiling crop, but is of minor value for silage. The hay is equal in feeding value to that of timothy, millet, or Johnson grass.
It is being utili/ed more and more as a summer pasture in the. Central and Southern Slates and is valuable as a pasture in the irrigated districts of the Southwest There is less danger of prussic-acid poisoning in pasturing or feeding Sudan grass than larger sorgliums, but care must, be observed in pasturing the grass, especially in the Northern States.
Feeding cvperinients have shown Sudan grass to be an cviclient roughage for work animals and stock cattle and only slightly less valuable than alfalfa for milk cows.
Seed production is profitable only in certain favored localities. Johnson grass seed is dangerous as an adulterant in Sudan grass seed south of the thirty-eighth degree of latitude only. 'I line Johnson grass behaves as a perennial and is dillicull to eradicate.
Sudan grass hybridizes freely with the sorghums, and care is necessary to keep it from becoming a mongrel crop as have many of the sweet sorghums.
