FIELD CROP OF CORN — FERTILIZER EXPERIMENTS. 



Three acres of corn was planted in rows 3 feet apart, June 10, on a soil of a liglil 

 clay loam character. One-third running across one end of the field was in clover the 

 previous year; in grain in 1902, and roots in 1901, for which crop 30 one-horse cart 

 loads of stable manure was u.sed per acre. One-third running across the centre of the 

 field was in grain last year, having been manured in 1902 for roots at the rate of 35 

 one-horse cart loads per acre, and one-third running across the other end of the field 

 was in roots last year, having been manured for that crop with 35 one-horse cart loads 

 of staJole manure per acre. The rows ran lengthwise of the field across each of these 

 three diiferently treated pieces of the field. The two former, clover and grain siubble, 

 were ploughed the fall previous, and the third, on which roots were grown, was not 

 ploughed in the fall. This spring the whole field was worked up by going over it once 

 each with the disc and spade harrows, after which stable manure at the rate of 20 tons 

 per acre was scattered broadcast with the manure spreader and ploughed under. The 

 ground was again gone over with the spade, springtooth and smoothing harrows, and 

 put into good tilth. 



Four varieties of corn of | acres each were planted. One- third of each variety 

 was fertilized in addition to the manure with 400 lbs. of fertilizer per acre; one-third 

 with 200 lbs. per acre, and the other third manure only. The fertilizer was scattered 

 broadcast and harrowed in. Each plot of ;1 acre was six row.s running the entire 

 length of the field. 



The first frost on September 1, which was much earlier tlian u>ua], damaged the 

 crop slightly; while a severe frost on September 23 of 9° did considerable dama.ge, 

 and very materially reduced the yield per acre. The following table gives the name 

 of variety sown, how treated, and yield per acre: —
