EXPERIMENTAL FJ.RMS 



9-10 EDWARD VII., A. 1910 



It is to be observed that very considerable differences exist in this series : the 

 percentages of dry matter range from 13-14 to 10-66, a difference equivalent to 19 per 

 cent of the total dry matter; the sugar-content, from 7-07 to 4-47 per cent, a 

 difference amounting to 37 per cent of the total sugar. These results clearly indicate 

 the advisability of considering feeding value, in addition to yield per acre and keeping 

 quality, when selecting the variety to sow. 



The averages for the past five years are given in the subjoined table, and the 

 differences to be remarked are, we think, for the most part to be attributed, to the 

 characteristics of the seasons of the different years. 



Mangels — Average Composition — 1904-1908. 



The averages for 1908 are seen to fall somewhat below those of the preceding 

 season. 



Turnips. — Thirteen varieties have been analysed, and while the differences in 

 dry matter are very similar in amount to those observed in mangels, the sugar-content 

 throughout the series is most constant. This peculiarity has been noticed every season 

 since this investigation began. 



A comparison of the results in the following table with those for this crop growni 

 in 1907 show that heredity is as i>otent in turnips as in mangels — the relative position 

 of a number of the better known varieties being the same for both years.
