crop for broadcast seeding in this state. Sudan grass is 

 better for that purpose. 



Time of Seeding. 



Special tests have been conducted at Brookings and 

 Highmore for the purpose of determining the best time 

 to seed Sudan grass. The following table shows the re- 

 sults obtained at various dates of seeding. As amber 

 cane is very similar to Sudan grass in its temperature 

 requirements it is safe to assume that the results of these 

 tests will apply to it also.
