Figure 8. — Root system of buffalo grass before tbe drought, showing depth in feet. 



Buffalo grass also has distinct 



advantages 



for lawns, golf courses. 

 and athletic fields in the dry Plains (56) (fig. 9). 



Several thousand individual plants of buffalo grass have been iso- 

 lated and studied at Woodward and other stations in the Plains. 

 This material displays highly significant differences in density, vigor, 

 production, spread, seeding habits, resistance to nematodes, and ability 

 of the foliage to remain green late in the season ; all of which indi- 

 cate the possibilities for improvement by intensive selection and 

 hybridization.
