EXPERIMENTAL FARMS 



4 GEORGE V., A. 1914 



there is an additional factor to be taken into consideration, and that heredity also has 

 an influence in determining the composition of mangels. 



TURNIPS. 



Nineteen varieties of turnips grown on the Central Farm last season have been 

 analyzed and the results recorded in the subjoined table in order of their dry-matter- 

 content.

It will be observed that very considerable differences occur as regards dry matter 

 but that, unlike as is the case with mangels, the sugar-content is fairly constant. We 

 do not consider that the value of turnips to the practical feeder would be measured 

 directly by the percentage of dry matter present, but there can be no doubt, with 

 data such as the foregoing as the result of one season's crop, that very considerable 

 differences in nutritive value do exist among the many varieties found on the market. 



In the following tabular scheme the averages obtained since 1905 are presented.
