p. 8: Crimson clover is a prolific seed-producing plant and 
yields of 5 to 10 bushels per acre are common, depending upon the 
thickness of the stand, the amount of growth that is produced, and 
the care exercised in harvesting the seed. The florets are self- 
fertile, but bees are effective in tripping and transferring the 
pollen, with a consequent in cre a se in the nu mber o f seed per hea d . 
The placing of colonies of honeybees adjacent to blooming f ields 
will effectively increase pollination .
