and Colorado. It is adapted to all soil types but makes its best growth on 

 the sandier soils. It is valued as a pasture and hay plant because its seed 

 awns are not so large or troublesome as those of the other stipagrasses. 



Mandan is superior to common green needlegrass in vigor, size, 

 and yields of forage and seed. Stands are easy to establish, and 

 seedlings can take considerable abuse from blowing soil and grass- 

 hopper attacks. Mandan starts growth about a week later in the spring 

 than crested wheatgrass in the same area and reaches maturity about 

 3 weeks earlier. 



SUDANGRASS 



Sudangrass is a summer annual grown throughout the United States. 

 Largest acreages are in the semi-arid regions of the Dakotas, Nebraska, 

 Kansas, Oklahoma, Texas, and Colorado. 



It grows well on fertile loam and sandy or heavy clay soils but does 

 poorly on wet or highly alkaline sites. It may be used for pasture, hay, or 

 silage. Sudangrass is very drought tolerant and makes rapid growth from 

 late seedings. Plants may contain toxic quantities of prussic acid after a 

 severe drought or frost. 



Piper is a variety having a lower prussic -acid potential, a greater 

 production potential, and a higher degree of resistance to leaf blight 

 and anthracnose than common Sudangrass. It is an important variety 

 in the Dakotas and Nebraska and in all States to the east. 



Greenleaf is a vigorous, leafy variety that is highly resistant to leaf 

 diseases. It matures later than most varieties and is particularly 

 adapted to Kansas. 



Wheeler is an older variety that is early and dry stemmed, but it is 

 susceptible to leaf diseases. It is grown principally in Kansas and 

 Colorado. 



Lahoma is a sweet, wide -leafed, late -maturing variety which is quite 

 resistant to the leaf diseases and insects normally encountered in 

 Oklahoma and Texas. It yields less than common Sudangrass but the 

 forage is of better quality. 



Sweet 372 is a highly palatable variety that produces a heavy crop of 

 seed, and possesses some resistance to foliage diseases, charcoal 

 rot, and chinch bugs. It is grown extensively in Texas. 



Tift is a late -maturing variety that is noted for its disease resistance 

 and for its high yields in those States south of the Ohio River and in 

 eastern Oklahoma and Texas. 



SWITCHGRASS 



Switchgrass is a sod -forming plant grown principally in western 

 Nebraska, Kansas, Oklahoma, and Texas, and in eastern Colorado and New 

 Mexico. It occurs on almost all soil types but thrives best in low moist 

 areas of relatively high fertility. It furnishes grazing early in the spring,
