 FIELD CROP OF MANGELS — FERTILIZER EXPERIJIENTS, 



Four acres of mangels were sown June 4 and 9 on soil of a liglit clay loam char- 

 acter. This land was adjoining that on which the com and turnips wore 

 grown. One-third running across one end of the tield was in clover the previous 

 year, in grain in 1902, and in roots in 1901, for which crop 30 one-horse cart loads of 

 stable manure per acre was used. One-third running across the centre of the field 

 v/as in grain last year, having been manured in 1902, for roots, at the rate of 35 one- 

 horse cart loads per acre, and one-third running across the other end of the field was 

 in roots last year, having been manured for that crop with 35 one-horse cart loads 

 of stable manure per acre. The rows ran lengthwise across each of these differently 

 treated pieces of the field. The pieces on which clover and oats were grown last year 

 were ploughed in the fall, but the root piece was not ploughed urtil this spring. This 

 spring the whole field was vrorked up by going over it once each with the dis-c and 

 spade harrows, after which stable manure at the rate of 20 tons per acre was scat- 

 tered broadcast with the manure spreader and ploughed under. The ground was 

 again gone over with the spade, springtooth, and smoothing harrows, and put into 

 a good state of tilth. 



Four varieties of mangels were sown. One-third acre of each was fertilized, in 

 addition to the manure, with 500 pounds of fertilizer per acre. One-third with 250 

 pounds of fertilizer per acre in addition to the manure, and the other third, manure 

 only. The fertilizer was scattered broadcast before the land was run up into rows 24 

 inches apart. The seed was sown with the hand seed drill in bunches one foot apart. 

 Each plot was one-third acre, or eight rows running the entire length of the field. 

 This field did not make a satisfactory growth, owing to the extremely dry weather 

 prevailing during the first part of the season. The later growth was fair. The cut- 

 worm did considerable damage. The following table gives results obtained.
