There are no appreciable differences in the yields with the 

 different treatments. Evidently on Aroostook Farm it is indi- 

 cated bv these trials that potash is not a limiting factor in grow- 

 ing oats. The stands were too uneven at Highmoor Farm to 

 warrant conclusions. It is not probable that the addition of 

 potash explains the reduced yields that apparently uniformly 

 followed its increased application at Highmoor Farm.
