For a flint variety it produces a generous quantity of fodder containing 

 a good percentage of grain. Pride of the North dent corn makes a very 

 nutritious silage as grown at Ithaca, but the tonnage is rather low in com- 

 parison with other varieties. It is early enough to mature seed in many 

 sections. and where conditions are favorable will produce a fair quantity 

 of fodder. Wood's Northern White, Stony Kill White Cap, and Leaming 

 are later varieties that cannot be expected to reach maturity at Ithaca 

 except in very favorable seasons. Eureka Ensilage and Blue Ridge 

 Ensilage are southern-grown varieties and cannot be acclimated to New 

 York conditions. The Eureka variety is grown for tlie silo by numerous 

 farmers in New York, while the Blue Ridge variety is said to be very 

 popular in northeastern Ohio. The former failed to produce any grain 

 when grown at Ithaca; the latter produced immature ears. 



A correct idea of the production of nutrients from each variety cannot 

 be obtained without an analysis of the fodder at harvest time. The vari- 

 eties grown at Ithaca have been anal^^zed by the Department of Agri- 

 cultural Chemistry soon after harvesting in both years. These analyses 

 and the weighed yields for each variety form the basis for the following 

 table :

If yield of dry matter alone could be used as a guide to determine the 

 best kind of silage corn to grow, the problem would be comparatively easy 

 to solve; but the degree of maturity in corn fodder has been found to in- 

 fluence its digestibility and that of the silage made from it. The dry matter 

 in very immatiu^e corn plants is less digestible and nutritious than in
