EXPERIMEyTAL FAIiMi? 



4-5 EDWARD Vll., A. 1905 



to ascribe the differences observable from year to year, entirely to climatic 

 causes, but there can be no doubt that the percentage of sugar (the most valu- 

 able nutrient) is particularly influenced by the character of the season. lO 

 would seem from our observations that heavy rains and low temperatures in 

 the late summer months had an injurious effect upon the sugar content of the root. 

 From investigation with sugar beets it seems evident that ideal climatic conditions 

 for sugar production include a comparatively low mean summer temperature, certainly 

 not higher than 70° F., an evenly distributed bi;t not excessive rainfall during May, 

 June, July and August, and warm and moderately dry weather during September and 

 October.

Mangels. — Ten varieties of mangels were examined. The lowest percentage of 

 dry matter was 9'24:; the highest, 13.92; the difference is 4'G8 per cent, or practically 

 33 per cent of the total dry matter. In sugar, the percentages vary from 4"75 to 9*13, 

 or a difference of 4'43 per cent, equivalent to 49 per cent of the total sugar. 



The ' Sugar Mangels,' the first six given in the table, as in past years, are char- 

 acterized (with one exception) by an excellent dry matter and sugar content. These 

 are followed by the variety kno-wn as Gate Post, including the Mammoth Long Eed 

 which is probably the same mangel under another name. The Giant Yellow Globe 

 and Giant Yellow Intermediate close the list with less dry matter, though showing a 

 very fair proportion of sugar. 



Carrots. — The Ox-heart and Improved Short White have given results practically 

 identical as regards dry matter, and very close as regards sugar. The Half Long 

 Chantenay is somewhat richer than these in both respects. 



It will be observed that, taken as a class, carrots do not furnish the same amount 

 of dry matter as mangel^, and fall considerably below the latter in respect to sugar 

 content. 



Turnips and Swedes. — Four varieties were analysed. Of these, the Xew Century 

 gtands highest, both in respect to dry matter and sugar, closely followed by Skirvings.
