 the findings of Maine and Pennsylvania Station from direct 

 trials. 



Green weights, dry matter and digestible substance, per 

 acre in corn forage from southern and northern-grown seed.

This shows larger yields of green forage in every instance 

 from Southern corn, which likewise, leads in dry matter and total 

 digestible substance, although percentagely lower in digesti- 

 bility as shown by Jordon. 



When to Use Southern Corn for Silage. 



From the table it appears that we are assured of larger re- 

 turns of total dry and digestible matter at the North by the use 

 of large Southern varieties of corn. Southern corn should not be 

 grown for either silo or forage purposes, however, unless the cli- 

 matic conditions permit the ears to develop grains of corn which 

 reach the glazing stage at time of harvest. This variety of corn 

 will prove a favorite for both silage and dry forage where there 

 is an urgent demand for the largest possible amount of coarse, 

 palatable forage from a given acreage. By the use of the South- 

 ern varieties of seed corn at the North the stockman can provide 

 an enormous quantity of roughage from a given area. 



On the other hand the stockman who has a fair supply of hay, 

 straw or stover at command will fill his silo with a richer feeding 

 stuff than that produced by Southern corn, and for this purpose 

 will use varieties of flint or dent corn which will fully mature in 

 his locality, planting the crop in such manner as to secure a 

 relatively large proportion of grain to roughage. Silage made 

 from the smaller varieties of corn, carrying a considerable pro-
