MANGELS AS FORAGE 285 
Mangels versus corn 
The relative production of dry matter in a crop 
of fodder corn and in mangels is well shown by an 
experiment made by the New Jersey Station in 
1894. The soil was good, and the plots on which 
the crops were grown similar in character. The 
tonnage yield and yield of nutrients per acre were 
as follows:

The first point of importance shown by this 
comparison is that the total dry matter contained 
in the crop of mangels was nearly 25 per cent less 
than in the fodder corn; and for every pound of 
dry matter contained in the crop it was necessary 
to handle twelve pounds of water, while in the 
corn fodder the proportion of dry matter to water 
was as 1 to 3.2. It is shown, also, that in feed 
constituents the corn fodder furnished nearly five 
times as much crude fat, and four times as much 
crude fiber as the mangels and 20 per cent more 
carbohydrates. The feed constituent furnished 
in greatest amount by the mangels is crude pro-
