5-6 EDWARD Vll., A. 1905 



EXPERIMENTS WITH MANGELS. 



Seventeen varieties of mangels were sown in uniform test plots. The land was a 

 clay loam manured in 1900 for roots, followed by grain in 1901, clover and timothy in 

 1902, grain again in 1903, and clover hay in 1904, It was ploughed early last fall, and 

 a light coat of aftermath turned under, it was cultivated twice before winter and again 

 in the spring. Barnyard manure was then spread with the manure spreader at the 

 rate of 20 tons per acre; and ploughed under and again cultivated thoroughly. Com- 

 plete fertilizer at the rate of 500 lbs. per acre was then sown broadcast and harrowed in 

 with the smoothing harrow. Rows were made 24 inches apart, rolled down and sown 

 with the Planet Jr. hand seed drill, in bunches, 12 inches apart in the row and from 

 4 to 8 seeds in a bunch. When about 3 to 4 inches high they were thinned out, leaving 

 one plant in each spot. Two sowings were made of each variety, the first sowing was 

 on May 25 and the second on June 8. The mangels were all pulled on October 12. 

 The yield was calculated in each case from the weight of roots gathered from two rows 

 each 66 feet long. The following were the yields obtained : —

FIELD CROPS OF MJ^NGELS. 



Two and a half acres of mangels were grown in two lots of one acre each, and one 

 lot of one-half acre. Three varieties were used. Yellow Globe, Yellow Intermediate 

 and Mammoth Long Red. The land was a clay loam, in a good state of fertility. The 

 previous crop was clover hay. The sod was ploughed in the early fall and worked up 

 twice with the spade harrow^ In the spring it was again well worked up, after which 

 barnyard manure was spread on with the manure spreader at the rate of 20 tons per 

 acre, and ploughed under; this was then well worked up. To one-third of each acre 

 was added commercial fertilizer at the rate of 500 lbs. per acre, to another third at the 

 rate of 250 lbs. per acre, and one-third left with manure alone. The mangels were 

 sown in drills 26 inches apart They were sown June 1, and harvested October 10 to 

 14. Tho following yield was obtained: —
