EXPERIMENTS WITH BUCKWHEAT. 

 Five varieties of buckwheat were sown in uniform test plots of one-fortietli acre 

 each. They were sown June 20, and cut September 1 and 2. The land was a clay 

 loam that had been in clover and timothy the previous season. This land had received 

 a dressing of barnyard manure in 1902, when a crop of roots was growru No fer- 

 tilizer of any kind was used since. The sod was ploughed in the fall of 1904 and 

 worked up well this spring. The following yields were obtained : —

FIELD CEOPS OF GRAIN. 



Seventeen acres of field grain was grown. Ten acres of which was in plots of two 

 acres each, the remaining seven acres in one lot. The land was a clay loam, the pre- 

 vious crop having been roots and corn, for which crop barnyard manure at the rate of 

 20 tons per acre was used. The plots ran crosswise of the field, the roots and com 

 plots having been run lengthwise of the field the previous year, consequently each grain 

 plot was on the like amount of root and coi'n land. The land was ploughed in the 

 spring and well harrowed, after which the grain was sown with the seed drill and with 

 3 bushels in the case of oats, 2 bushels in the case of barley and 3 bushels in the case of 

 mixed grain, Mammoth Red clover at the rate of 7 lbs.; Alsike clover, 3 lbs., and 

 Timothy seed 12 lbs. per acre was sown with this crop. The following is the crop har- 

 v^ted : —

FIELD CROPS OF ]\nXED GRAIN. 



Eight acres was sown with mixed oats, barley and pease. The land was a clay 

 loam in a very poor state of fertility, not having received manure or fertilizer of any 

 kind for at least ten years. This crop was sown May 6 and cut August 23. The yield 

 was 30 bushels, 15 lbs. per acre, weighing 40 lbs. per bushel. 



Five acres mixed grain was grown. The land was a light clay loam. The previous 

 crop vras buckwheat, for which crop barnyard manure at the rate of 10 tons per acre
