It is clear that the rotation must vary widely according to 

 the particular circumstances; thus in sugar-beet growing dis- 

 tricts the area occupied annually by this crop varies from 11 to 

 33 per cent, of the farm. Hitier recommends the adoption of a 

 rotation in which lucerne or other leguminous fodder crop 

 takes a large place, in order to bring the sugar-beet crop to a 

 just proportion, avoid the increase in fungus and insect pests, 

 and permit the maintenance of a large head of stock to 

 produce dung. Long rotations are sometimes practised; thus 

 in Saxony a rotation followed on some of the better sandy- 

 loam soils is : — Sugar-beet with dung, wheat, rye, potatoes 

 with dung, oats with clover, clover, wheat with dung, sugar- 

 beet, barley, rye, sugar-beet with dung, wheat. 



It is believed in Germany that sugar-beets after clover are 

 usually attacked by insects and also ripen later, but Kiehl 

 found, on the basis of 14 years' observations, that sugar-beets 

 after clover gave a considerably higher average yield than 

 sugar-beets after wheat. The 14 years' average was as 

 follows : — 



After wheat .. ... n "io tons per acre with i'6o tons of sugar 

 clover ... .." 12-27 „ 173 J5 



This shows a greater average yield of i'ij tons of sugar- 

 beet containing over 2\ cwt. more sugar after clover than 

 after wheat. 



Manuring. — The manuring of the sugar-beet is a question 

 of great importance, and it is necessary to consider not only 

 the kind and quantity of manures to use, but the time and
