EXPERIMENTS WITH [MANGELS. 



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

 clay loam, the previous crop being clover hay. It was ploughed early last fall and a 

 light crop of aftermath turned under, and cultivated in the spring. Barnyard manure 

 at the rate of 20 tons per acre was spread on with the manure spreader and ploughed 

 under and cultivated again. Complete fertilizer at the rate of 500 lbs. per acre was 

 then sown broadcast and harrowed in with the smoothing harrow. The rows were 

 made 24 inches apart, raked down and sown with the Planet Jr. hand seed drill in 

 bunches 12 inches apart in the rows and from 4 to 8 seeds in each bunch. ^Vhen 

 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 on June 14 and the second on June 28. 

 This crop made very unsatisfactory growth, evidently owing to the lateness of the 

 sowing and the extreme drought in the latter part of the season. The mangels were 

 all pulled October 17. The yield was calculated'in each case from the weight of roots 

 <?athered from two rows, each 66 feet long. The following are the results obtained : —

FIELD CROP OF MANGELS. 



Three varieties of mangels were grown. Yellow Globe, Yellow Intermediate and 

 Mammoth Long Red in three plots of %o acre each. The land was a clay loam in a 

 good state of fertility, the previous crop having teen clover hay. The sod was ploughed 

 jn the early fall and worked up with the spade harrow. In the spring it was again 

 well worked up and barnyard manure at the rate of 20 tons to the acre was spread on 

 with the manure spreader, ploughed under and well worked up. To one-third of each 

 plot was added complete fertilizer (Bowkers Square brand) 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.
