Treatment of Wheat Stubble to be sown to Oats. 



Plots 2, 3 and 5. whicli were not piuughed, were conspicuously weedy, as com- 

 pared to the ploughed idiots. The difference in yield between the discing and plough- 

 ing is hardly as great as would be expected. Plot 5, which received no cultivation is 

 the lowest in yield of any, as might be expected. The three plots on wKich the stubble 

 was burned are the three lowest in yield. Xo very distinct difference can be observed 

 between spring and fall ploughing, but what advantage there is, is in favour of fall 

 ploughing. In the case of oats, the plot that was cultivated (disced) in the fall and 

 ploughed in the spring, gave best results. 



SEEDIXG TO GRASS AND CLOVER. 



The group of plots which reached the result-producing stage in this experiment 

 in 1913, were seeded as per the directions given below, in the year 1912. Plots 1 to 8 

 received the required preparatory treatinsent in previous years. Plots 9, 10 and 11, 

 rciiuirin,g two previous grain crops, did not have more than one, as the experiment was 

 laid out only in 1911, and the land was in summer-fallow in 1910. The first crop was 

 cut June 27 and the second August 22.
