HATCH EXPERIMENT STATION. 



[Jan. 



Maercker * has quoted Moser to the effect that corn raised 

 on muriate of potash contains more protein, and therefore 

 has a higher food value, than when grown on sulfate. Three 

 experiments here, one in 1898 and the two this year, have 

 not shown this to be the case. It would appear that the 

 muriate of potash is equally as good for the corn crop as 

 the sulfate. 



Soy Beans {Sulfate v. Muriate of Potash). 

 Through accident the product of the soy bean plots was 

 mixed ; and I can only report that during the early part of 

 the season the beans on the sulfate appeared much better 

 than the others. Later this apparent superiority was lost 

 in large measure, as judged after careful examination. 



Cabbages (^Sulfate v. Muriate of Potash). 

 This crop (Warren cabbage) occupied plots 13 and 14. 

 The growth on the sulfate of potash was from the start much 

 better than on the muriate, and this superiority was main- 

 tained throughout the season. The yield is shown in the 

 table : — 



It will be noticed that the sulfate of potash plot gave much 

 the larger and more valuable crop. It should be pointed 

 out that, on account of difference of growth due to acci- 

 dental conditions, the above table has been made to include 

 the yield for only about one-ninth of an acre. The product 

 of plot 14 sold at a price (5 cents per head) which would 

 have made the product of one acre of such cabbages worth 

 about $250, while the product of the other plot was worth 

 only at the rate of about $200 per acre.
