EXPERIMEyTAL FARMS 



5 GEORGE v.. A. 1915 



S r M M ER- FALLOW TREATMENT. 



The rotation used by the majority of fanners in southern Saskatchewaii is: — 

 First year. — Summer-fallow. 

 Second year. — Wheat. 

 Third year. — Wheat or oats. 



This means that one-third of the farm is in summer-fallow each season, con- 

 sequently information as to the bc.-t methods of sunuiier-fallowing is of, vital im- 

 portance. An experiment including- tiftccn different kinds of treatment was started 

 in 1911. As climatic conditions will affect the yield materially, the average results 

 for a number of years are necessary before deductions may be made. The table 

 below outlines the different methods of cultivation and shows the yields of wheat 

 as a result thereof. The yields of oats following the wheat are also given. It will 

 be noted that the plot ploughed four inches deep in June, cultivated and ploughed i 

 inches deep again in September gave best returns. The only other method th.it 

 yielded nearly so high was the land that was fall disced before summcr-fallowiiog. 

 ploughed 6 inches deep in June, harroAved and packed as necessary. It must be 

 remarked, however, that with the latter method weeds are under better control and 

 the crop of oats following the wheat has surpassed all the others, so that, all things 

 considered, it may be regarded as the most generally satisfactory treatment. 



Treatment of Summer-fallow to be sown to Wheat followed by Oats.
