CLOVERS KENTUCKY BLUEGRASS. 35 



uiHlcr "othor tamo j^'ra^iscs. ^ As Nebraska is croditod Avith 4*J,(»(»0 

 acres of clover and i>2,0<>() jicivs of other tame orasses, it is qiiit(> likidy 

 that a hir*:fe ]H()])ortion of th(^ latter area is devoted to timotliy and 

 cIo\"(M" mixed. Red clover has heen orown upon the Nel)raska Station 

 farm for many yeai's with threat success. 



]\Iammoth clo\'er is a \ariety of red clover of more \'igorous ji^rowth 

 and lon«,^er lived than t\\v ordinary kind. The seed was sown at the 

 Nel)raska Station in I'.mki. and uave a <ifood stand, a vigorous growth, 

 with good fall pasture. The following year it was su])jected to a severe 

 test h\ drought, hut withstood this better than any other clover upon 

 the farm. It was about half winterkilliMl in tlu- winter of 11R)2-1903. 



Alsike i-lover (7'/v'/V/^//y/ Juihr'nlmii) is a i)er«Mmial clover, in size 

 and appearance intermediate between red and white clover. It is 

 adapted to more moist gi'ound than red clover and is reconmiended as 

 a constituent of wet pastures. In Nel)raNka it does not usually grow 

 tall enough foi- hay. but is a line clover for i)asture. On the station 

 farm alsike has given good results in low spots in pastures and has 

 withstood drought well.

Kentucky l)luegrass ( /'v'/y/v/Av/.s/.s) is a native of Kurope and of the 

 northern part of the United States, but it is now widely cultivated; 

 it is also found as a wild grass throughout all the northern portion 

 of the United States, except the arid regions. IMuegrass is essentially 

 a pasture grass and can scarcely be excelled in regions where it reaches 

 its greatest development. In Neln-aska it thrives only in the eastern 

 counties over about the same range as timothy, though it is gradually 

 spreading westward. However, in many places lying west of the 

 normal range it is a common constituent of pastures, and is then usually 

 established in the more shaded situations. If there are shade trees or 

 hedges, the ])luegrass is quite certain to obtain a foothold and spread 

 outward, holding its own very well with even the native grasses. It 

 gives early and late pasture, but dries up in sunnner. 



The seed should be sown very early in the spring, on the melting 

 snow if possible, at the rate of about 26 pounds of good seed per acre. 

 If the seed is cliatfy more must be used. It is customary to sow with 

 bluegrass a little white clover — 2 or 3 pounds. The latter, however, is 

 usually widespread in the bluegrass region and soon comes in itself. 



Results at the Nebraska Station show that bluegrass furnishes con- 

 siderable pasture, especially during spring and fall, as indicated in the 

 paragraph on pastures. 



Closely allied to Kentucky bluegrass is Canada or Canadian blue- 

 grass {Poa comjyressa). This differs from the former in having a 

 distinctly flattened stem, being of a bluish-green color, in having 

 smaller tiower clusters, and usuall}^ growing less tall. It is the com-
