HABVEsTlXG. 



The method of harvesting corn for silage is well understood. But 

 the stage of development at which to harvest requires some attention. 

 Farmers* bulletin No. 57S, U. S. D. A. gives the following comparative 

 value of ear vs. stover corn : 



TABLE 20 YIELD OF DIGESTIBLE MATTER IX CORX. 



A study of this table shows that the ear is the important factor in 

 determining the feeding value of a crop of corn. These figures probably 

 could not be duplicated in the Upper Peninsula, but the relative value 

 between ear and stover will hold irrespective of total yield. 



The following table taken from the same bulletin gives the weight 

 of protein, carbohydrate and fat produced by an acre of corn at two 

 stages of growth; the milk and the glazed stage.
