SORGHUMS. 



The sorghums require a considerable period of warm weather for 

 satisfactory growth, and as might be expected the greatest acreage 

 is found in the southern part of the region. There are in those parts 

 of South Dakota and Nebraska included in the area approximately 

 40,000 acres of sorghum. This acreage constitutes more than three- 

 fourths of all the land devoted to sorghum in the area. In South 

 Dakota most of the sorghum is found in the southern half of the 

 State just west of the Missouri River. The average yield per acre 

 is 1§ tons of fodder. It is planted mostly in rows, although there is 

 a small acreage sown broadcast in the eastern part of the region, 

 whore the moisture conditions are more favorable. 



The leading variety for this region is Dakota Amber, although 

 Minnesota Amber and Red Amber have given good results in the 

 southern part. The acreage of grain sorghum is insignificant. 



The average yields of sorghum gradually decrease west of Red- 

 field (fig. 5) until the lowest yield is reached at Havre, where it falls 

 below 1 ton per acre. At Mandan, Redfield, Sheridan, and Ard- 

 more, the Red Amber variety has given the largest yields, but over 

 most of the region Dakota Amber has proved most popular, as it is 

 better adapted to a short growing season. At Redfield the avenge 

 for this variety is about 3.5 tons per acre and at Belle Fourche, 

 Anlmoro, and Willistofl from 2 to nearly 3 tons per acre. The 

 yields reported for Ilighmoro are too low as compared with those 

 from other stations, probably because the data were obtained during 

 a period of years when conditions were not especially favorable. 

 The Lighl yields at Moccasin are largely duo to the relatively short 

 and cool growing season. 



Table K) gives the results ^i' tests that have been conducted at 

 \ arious points in the region.
