EXPERIMENTS WITH MANGELS. 



The ground selected for the mangel plots was a light clay loam. It 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. The clover sod was ploughed last 

 fall and this spring was worked up with the spade harrow and manured with 25 one- 

 horse cart loads of stable manure per acre, which was ploughed in and worked up with 

 the spade and springtooth harrows. Complete fertilizer at the rate of 400 lbs. i^er acre 

 was sown broadcast and haiTowed in with the smoothing harrow, after which row<3 

 were run 24 inches apart. The plots were sown May 30, and a duplicate set on 

 June 13. The rows were raked off and the seed sown with the Planet Jr., hand 

 seed drill. The crop was harvested October 12. The yield per acre has been 

 determined from the weight obtained from two rows, each 66 feet long. The 

 mangel crop suffered considerably from the ravages of the cutworm. The early-sown 

 plot of Prize Winner Yellow Globe was so badly destroyed that reliable weights could 

 not be obtained. The continued dry weather until 'after the middle of July also pre- 

 vented satisfactory growth, while the latter part of the season was fairly suitable.
