134 STORRS AGRICULTURAL EXPERIMENT STATION. 
From table 38 it will be seen that the nitrogen supplied in 
the fertilizers had considerable influence on the percentage of 
protein. The average percentage of protein in the water-free 
substance of the crop on the mineral plots was 8.87 per cent., on 
the plots with 25 lbs. of nitrogen 10.24 per cent., and with 75 lbs. 
of nitrogen, 12.72 per cent. This illustrates the double value of 
nitrogen on the grasses. The yield is generally increased with 
the larger quantities of nitrogen used, and the protein, and hence 
the feeding value of the crop is considerably increased.
