SUMMARY. 



1. Sorghum as a forage crop is worth considering 

 carefully in South Dakota because it may be used as a 

 catch crop due to the fact that it matures quickly, yields 

 fairly well and is adapted to hot weather and limited 

 moisture conditions. Sorghum as a forage crop is not 

 superior to corn in seasons that are reasonably favorable 

 to corn. 



2. Several difficulties are encountered in growing 

 sorghum due to the small seed, danger of planting too 

 deep and the slow growth of the young plants. 



3. Variety tests of sorghums in South Dakota in- 

 dicate that Sudan grass is best for hay, the amber canes 

 for coarse fodder and dwarf milo for silage. 



4. The soil preparation necessary for corn is suf- 

 ficient for sorghum. 



5. Where moisture is plentiful Sudan grass gives 

 best results drilled in 6 or 12-inch rows. It can be used 

 as an intertilled crop if desired. 



6. All varieties of sorghum except Sudan grass 

 gave best results in method of seeding test when drilled 

 in rows 36 or 42 inches apart and cultivated. 



7. In date of seeding experiments Sudan grass gave 

 best results wlipn seeded between May 20th and June -1st. 

 It is safe to assume that these dates are also best for the 

 amber canes and dwarf milo, as these sorghums have 

 practically the same temperature requirements. 



8. Head selection should be practiced in securing 

 sorghum seed. 



9. Sorghum drilled in 36 or 42-inch rows may be 

 harvested with an ordinary corn binder. Shocks must 

 be built small. 



10. Sorghum drilled in 6 or 12-inch rows or sown 

 broadcast may bo harvested with a mower or grain 

 binder.
