TABLE XLVII 



Composition of Stovee and Geain in Corn. 



Basis 



Watbr-fbeb 



In well-developed corn planted at proper distance for 

 maximum yield, the weight of shelled corn will be almost 

 equal to the weight of stalk. Increasing the rate of 

 planting has very little effect on the composition of either 

 grain or stalk, but, as the proportion of stalk to grain 

 increases, it is evident that the analysis of the whole 

 plant will show a decreased percentage of protein and fat 

 and an increased percentage of fiber. The total protein 

 per acre, however, will increase. Silage from very thickly 

 planted corn will not be so rich in percentage of protein 

 and fat, but the total yield per acre will be greater. 



By reference to Table XLIV it will be seen that the rate 

 of planting has more effect on percentage of ears in a dry 

 season than in a seasonable year. The same would be true 

 on poor soil.
