 ceived manure only. The following yields were obtained per acre: —

FIELD CROPS OF MANGELS. 



The land on which the field mangels were grown was a clay loam in a good state 

 of fertility, the previous crop having been clover, the aftermath of which was ploughed 

 under in the fall of 1900. This was disc-harrowed the following spring, and 20 one- 

 horse cart loads of stable manure per acre was spread and ploughed under. This was 

 then worked up with the disc, spring-tooth and smoothing harrows, after which complete 

 fertilizer was sown broadcast at the rate of 400 pounds per acre on one-half of each 

 one acre lot and harrowed in. The other half acre of each lot was left without any 

 commercial fertilizer. 



Drills were run 24 inches apart, and the seed planted in holes one foot apart, made 

 with a marker and from 3 to 6 seeds were dropped in each hole. These were covered 

 by running a land roller over the rows. Four varieties of mangels were sown in these 

 plots, and the following yields were obtained : —
