EXPERIMENTAL FARMS 



2 GEORGE V.; A. 1912 



The Gate Post, it will be observed, has invariably proved the superior root; 

 seasonal conditions and size of root have from year to year caused considerable fluctua- 

 tions in composition, but the relative position of the two varieties under examination 

 has always remained unchanged. This fact points unmistakably to the conclusion 

 that the composition of a root is in a large measure controlled by hereditary influences, 

 and lends weight to the view that improvement in field roots, as regards feeding value, 

 might be brought about by well directed breeding experiments. 



TURNIPS. 



Ten varieties have been examined. The differences in composition are not so 

 pronounced as in mangels, but are nevertheless sufficiently large to warrant the con- 

 clusion that all varieties are not of equal feeding value. In this series, one ton of the 

 richest is equivalent in dry matter to 2,308 lbs. of the poorest.

The roots of the past season were larger than usual and this, no doubt, furnishes 

 the explanation for the somewhat low percentages of dry matter and sugar recorded in 

 the foregoing table.
