266. Yield of root crops. — The Cornell Station^ secured the foi- 

 lowing yields of fresh and dry matter per acre with various root 

 crops during three years of field trials. Potatoes are added for 

 comparison :

267. Sugar beet, Beta vulgaris, var, — This root has been marvel- 

 ously developed for the single purpose of producing sugar. Because 

 it sets deep in the ground the sugar beet is more expensive to culti- 

 vate and harvest than most other roots. If liberally fed, this root is 

 liable to produce scouring because of its high sugar content. Farm- 

 ers patronizing sugar factories should utilize cull beets as well as 

 the tops. (656, 757, 873) 



268. The mangel, Beta vulgaris, var. — Tho the most watery of all 

 roots except the white turnip, the mangel has a high total dry mat- 

 ter content because of its enormous yield. As the large roots stand 

 well out of the ground, the mangel is easily cultivated and har- 

 vested. Tho it yields less dry matter per acre than the sugar beet, 

 only half the labor is required to harvest the mangel, and further- 

 more this root keeps better than the sugar beet. The mangel is use- 

 ful for all kinds of farm stock except possibly the horse. Day of 

 the Ontario College- found that equal weights of pulped mangels 

 and grain caused pigs to fatten faster and on less dry matter than
