Seed. — The seed of red top is 

 usually mixed with much chaff, 

 that is, the glumes from which 

 the florets have fallen. The re- 

 cleaned seed contains a much 

 larger proportion of 

 seed and is correspond- 

 ingly heavier. Ordi- 

 nary red top seed weighs 

 lo to 12 pounds per 

 bushel. 



If red top is used alone 

 for meadow or pasture, 

 12 to 1 8 pounds of re- 

 cleaned seed should be 

 sown per acre. If ordi- 

 nary seed is used the 

 amount must be in- 

 creased to 50 or 60 

 pounds per acre. It 

 is much more satis- 

 factory to use recleaned seed. 

 If redtop is used in a mixture, 

 as is more often' the case, the 

 amount is reduced, often to 

 only I or 2 pounds of the re- 

 cleaned 

 seed per 

 acre.
