Food for g ra i n) roots, and potatoes In exactly the same proportion as 

 * the yields of straw. Straw and leaf production are especially 

 favored neither by the nitrogen of sulphate of ammonia nor 

 by that of Nitrate of Soda. On the contrary, a plant suffi- 

 ciently fed (not over- fed) with nitrogen, produces a more 

 favorable proportion of grain and roots to straw and leaves 

 than does a plant which is hungering for nitrogen. In brief,

the average results of the experiments conducted to test this 

 point are as follows : 



1. Barley.
