broadcast. With barley the loss from broadcasting, compared with 

 the results obtained from the use of the press drill, was 11 bu. 8 lbs. 

 per acre. For barley the ]jress drill gave better results than the com- 

 mon drill. 



()l the 15 varieties of oats tested in 1893 Banner gave the largest 

 yield, i>l bu. G lbs. per acre. Of the varieties of barley tested for 4 

 years the largest yields were made by Duckbill, Goldthorpe, and 

 Od: ssiu 



-Alixtures of small grain and peas were grown, and after threshing 

 the mixture it was found that the peas represented a very small pro- 

 portion of the grain produced, even when sown in larger quantity than 

 the small grain. Peas sown at the rate of .■> bu. per acre gave a hirger 

 yield than when the rate was 2 or 4 bu. per acre. 



Experiments were conducted with methods of destroying the trouble- 

 some weeds Af/ropi/ruiii (jJaucum and Rierochloa borealis. 



Sunflowers produced seed at the rate of 35 bu. per acre. The yield 

 of hay made by G species of grasses was determined.

 MacKay (Canada ExptL Farm.s Rpt. 1S93, pp. 273-2'.)2). — Among the 

 experiments conducted in 18!>3 at the experiment farm at Indian Head 

 w^ere the following: Variety tests of wheat, barley, oats, peas, corn, 

 turnii»s, mangel-wurzels, sugar beets, and potatoes, and experiments to 

 determine the best dates lor sowing wheat, barley, and oats. 



lied Fife wheat planted 2 in, deep May 4 gave a larger yield of giain 

 than when planted 2i in. deep. For wheat the press drill gave better 

 results than the common drill. The best preparation for wheat was 

 found to be a summer fallow; spring plowing gave much better results 

 than fall plowing. With barley the use of the press drill resulted in a 

 yield greater by 7 bu. per acre than that obtained by the use of the 

 common drill and greater by 9 bu. 28 lbs. than that obtained by sowiug 

 broadcast. Barley preceded by summer fallow yielded 48 bu. 10 lbs.; 

 when the preparation consisted of fall plowing of stubble the yield was 

 only 41 bu. 32 lbs. The use of 2 bu. of barley per acre as seed gave a 

 larger yield than If bu. or Ih bu. 



For oats summer fallow proved the best preparation ; spring plowing 

 3 in. deep gave a larger yield than fall i)lowing G in. dee]), Oats planted 

 with a press drill yielded lOU bu. per acre, with a common drill i^o 

 bu. 30 lbs., and broadcast 75 bu. 20 lbs. A larger yield resulted 

 from planting oats 3 in. deep than from [)lanting at a ^leptli of 2 in.; 2 

 bu. of seed per acre gave larger yiehls than 2i and 2i| bu. 



Of IG grasses sown only 2 produced a crop, 1 of which was Bror.ius 

 inermis. This grass was G in. high before a green blade could be seen 

 on the prairie, and it proved hardy in severe winter weather.
