Fertilizer and Seeding Experiments with Root Crops. 429 



TABLE \ll— Continued 



No difference was observed in the germination on the different plats. 

 On June 17, twenty-six days after planting, the plants on plats 1452 

 and 1462, which received only nitrogen and phosphoric acid, were much 

 larger than those on adjacent plats. This was also true of the plats 

 receiving a complete fertilizer, more especially those which received 

 the larger amounts. These differences were evident, throughout the 

 entire season, though they were not so striking during the latter part 

 of the period of growth. 



In the following table are given the apparent increase following the 

 use of fertilizers, the value of the increase, the cost of the fertilizer 

 used and the net gain or loss per acre. In determining the value of the 

 increase it was assumed that a pound of dry matter in the form of 

 mangels was equivalent, for feeding purposes, to an equal amount of dry 

 matter in corn. The increased yields of dry matter were obtained by 

 multiplying the apparent increases by 10.67% which was the average 

 per cent of dry matter on all plats. These results multiplied by the
