Table V. Norbiton Giant Mangel. 



In the case of the variety Norbiton Giant, nine plats were sown on 

 June 26, and these were compared with the nine plats near them, sown 

 on May 8. The results are shown in the following table: 



Note. — Although the number of plants per acre appears to be larger on the early-sown plats, this

THE EXPERIMENT OF 1906. 



The area devoted to the experiment consisted of 1.5 acres, 

 was in corn in 1905 and in 

 timothy for several years 

 previous. The soil is Dun- 

 kirk clay loam. 



The land was plowed 

 in the fall, after which it 

 was limed and manure ap- 

 plied at the rate of 10 tons 

 per acre. In the spring it 

 was disked as soon as it 

 was dry enough to work 

 (May 8). On May 11 the 

 following fertilizers were 

 applied : dried blood, 120 

 pounds per acre ; acid phos- 

 phate, 240 pounds per acre ; 

 muriate of potash, 120 

 pounds per acre. The fer- 

 tilizers were sown broad-
