EXPERIMENTS WITH TURNIPS. 



Twenty varieties of turnips were sown this year on a clay loam soil that had been 

 manured for roots in the season of 1900. Grain was grown in 1901, clover 1902, with 

 the second crop turned under and grain again in 1903. Clover in 1904, the aftermath 

 of this crop was ploughed under early last fall and cultivated twice with spade harrow. 

 In the spring this was again cultivated with spring tooth and disc harrows. Barnyard 

 manure was then spread on with a manure spreader at the rate of 20 tons per acre, 

 and ploughed imder and again thoroughly cultivated. Complete fertilizer at the rate 

 of 500 lbs. per acre was then sown broadcast and harrowed in with the smoothing har- 

 row. Rows were made 24 inch^ apart and the plants thinned out to one foot apart in 

 the rows. The yield was calculated from the weight obtained from two rows each Q'o 

 feet long. The first plots were sown May 26, and a duplicate lot sown June 9, and all 

 pulled October 16. Until about October 1 this crop appeared to be particularly good, 

 but made little increase after that date, owing to severe and continued drouth. The 

 following were the results obtained: —
