96 GRASSES AND HOW TO GROW THEM. 



of the blue grass rather than hinders it, since it brings 

 nitrogen to the soil. It also grows most vigorously after 

 the blue grass has begun its summer rest, hence the sea- 

 son of pasturage is prolonged. The two will also grow 

 thus together for an indefinite period. 



The amounts of seed to sow will vary with soil and 

 climatic conditions and with the combinations in which 

 the seed is sown. When sown alone on good soils and 

 without a nurse crop it is seldom necessary to sow 

 more than 20 to 28 pounds of good clean seed per 

 acre, but if sown in the chaff not less probably than 3 

 or 4 bushels per acre would be required. When sown 

 with Russian brome grass and white clover without a 

 nurse crop 6 pounds of the brome grass and 1 pound of 

 the clover, and 10 pounds of the blue grass per acre will 

 usually make a sufficient seeding. But to increase the 

 grazing the first year, it will doubtless be found profit- 

 able to add 3 to 4 pounds of timothy per acre. When 

 sown on low lands with timothy, red top and alsike clo- 

 ver, 4, 4 and 3 pounds each per acre of these respective 

 forage plants, with 7 pounds of blue grass ought to 

 suffice. When the mixture consists of blue grass, tim- 

 othy and medium red or mammoth clover, 7 pounds of 

 the blue grass, 6 of timothy and 3 to 4 pounds of medi- 

 um red clover per acre ought to suffice. When sown in 

 combination with many varieties of grass and clover, 

 as in making permanent pastures mixed in character, 

 usually not more than 5 pounds of blue grass per acre 

 will be required. Where white clover is not already es- 

 tablished in any locality, that is, where it has not been 

 grown long enough to lodge many of its seeds in the
