EXPERIMENTS WITH SUGAR BEETS. 



Three varieties of sugar beets were sown in uniform test plots in duplicate lots. 



The land was a heavy clay loam in a fairly good condition, on which wheat had 

 been grown the previous year. This was ploughed in the fall of 1909, well cultivated 

 in the spring of 1910, and barn-yard manure at the rate of twenty tons per acre spread 

 on the surface and ploughed under with a gang plough. It was again thoroughly 

 cultivated and commercial fertilizer, made up of (superphosphate, 1£ lbs.; bone meal. 

 1J lbs.; nitrate of soda, 1 lb.; muriate of potash, 1 lb.), mixed together and sown at the 

 rate of three hundred pounds per acre was spread on the surface and harrowed in with 

 a smoothing harrow. The sugar beet seed was sown in rows twenty-four inches apart 

 with a Planet Jr. hand drill, in bunches of from three to six in each, and one foot apart. 

 When the plants were from two to four inches high, they were thinned out, leaving one 

 plant in each spot. This gives an opportunity for selection of plants, always having 

 the selected one in the proper place. 



Besides this thinning, they were gone through twice with a hoe, and cultivated 

 from time to time at intervals of about one week. 



The first set of plots were sown June 3 and the duplicate set June 17, and all 

 pulled October 12. 



The yield was calculated from that obtained from two rows, each sixty-six feet 

 long. 



The following were the yields obtained : —
