EXPERIMENTAL FARMS 



5 GEORGE v., A. 1915 



Between the best and the poorest there is a difference of 3-56 per cent dry 

 matter, which means that 2,000 lbs. of the former has a feeding value equivalent 

 to 2,884 lbs. of the latter. These figures are significant and taken into consideration 

 with similar results from previous seasons, give emphasis to the statement that, in 

 the choice of the variety to sow, this question of composition may well be regarded. 



The averages for the past eight years are presented in the following table: — 



Turnips. — Yield and Average Composition, 1905-1913. 



As in the case of mangels, the turnips of 1913 are somewhat better than those 

 of 1912, but they have not given an average quite equal to that for the eight years 

 that this experiment has been in progress. 



The yearly averages show that considerable fluctuations may occur from season 

 to season as regards dry matter, but that in respect to sugar content the figure remains 

 fairly constant, or at all events that the range lies within narrow limits. 



C.VRROTS. 



This series includes six of the best known varieties. The results on the whole 

 are not quite so good as those of last year, though the percentage of sugar was not 

 affected to the same degree as that of the dry matter. Further, the records, show that 

 certain apparent irregularities have occurred, the explanation of which it is not easy 

 to find. Thus the White Belgian, which for several years has been closely associated 

 with the Mammoth Wliite Intermediate at the bottom of the list, is this year the 

 best of all.

In sugar content, the turnip seldom exceeds 1-5 per cent; carrots as a class are 

 richer in this constituent, though not possessing more dry matter. The sugar in carrots
