COMMERCIAL FERTILIZERS FOR TURISTIPS. 



Seven different varieties of turnips were sown in lots of 1 acre each. One-half 

 acre of each variety v/as fertilized with barnyard manure alone applied at the rate 

 of 20 tons per acre. The other half acre of each variety received .barnyard manure 

 at the rate of 20 tons per acre, and. in addition 400 pounds per acre of a commercial 

 fertilizer mixed in the following proportion: Superphosphate, li pounds; bone 

 meal, 1\ pounds; nitrate of soda, 1 pound; muriate of potash, 1 pound. 



Yields of Turnips with Manure alone and with Commercial Fertilizer in Addition 



to Manure. 



Of the seven tests made, tw,o only gave profits to compensate for the cost of 

 the fertilizer. As those results accord closely with those obtained in ijrevious 

 years, it seems evident that turnips on our soil are not benefited to any extent by 

 the use of the above commercial fertilizer in addition to the regular application of 

 barnyard manure.
