Table 16. — Hay yields of millet varieties at eight stations in the northern Great 

 Plains region in stated years. 



[Data in pounds per acre, field cured, except that the material at .Moccasin in 1922 and at Havre in 1921 

 and 1922 was air dried. The yield stated for 1922 at Moccasin was that of the Gold Mine variety. 

 The yield stated for 1919 at Hettinger was that of German millet. F= Killed by frost— not included in 

 the averages.]

SUDAN GRASS. 



There are no data on the acreage of Sudan grass in the region, but 

 it is grown to some extent, particularly in southern South Dakota 

 and northern Nebraska. Like the other members of the sorghum 

 group it does not thrive in cool weather. The yields of Sudan grass 

 for the most part have been less than those of sorghum or millet. 

 Table 17 gives the results that have been obtained at various experi- 

 ment stations during the past few years. 



The highest average yields, 3 and 4 tons per acre, have been obtained 

 at Redfield and the lowest average, about one-fourth ton per acre, at 

 Havre. The average yields at Moccasin are also very low, less than 

 one-half ton per acre. Results reported at other points for the most 

 part range from about 1 to 1J tons per acre, which in general is 

 appreciably less than the millet yields for the same stations. Except 

 at Redfield, Ardmore, and Williston the yields from row sowings and 

 from broadcast or close-drilled sowings are very similar. In dry 

 seasons Sudan grass gives the best results when sown in rows, but 

 when moisture conditions are favorable broadcast or close-drilled 

 sowings give better yields. While a longer season than is found in 

 most of the region is required for the best growth of Sudan grass, it 

 possesses possibilities in the more favorable situations south of 

 North Dakota. (Fig. 14.)
