EXPERIMENTS WITH CARROTS. 



Five varieties of carrots were sown in uniform test plots on June 6, and a dupli- 

 cate set June 20. 



The land was a clay loam in fairly good condition, on which grain 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 sur- 

 face and ploughed under with a gang plough. It was again thoroughly cultivated 

 and commercial fertilizer made up of (superphosphate, li lbs. ; bone meal, li 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 seed was sown in rows twenty-four inches apart, and the plants thinned out 

 by hand to about three inches apart in the rows. 



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

 long. 



The following were the crops obtained: —
