30 EXPERIMENTAL FARMS 



4 GEORGE V., A. 1914 



5. Studies of the influence of size and character of cultural implement* on 

 cost of crop production. 



6. Comparisons (in a limited way) of varieties of grain and forage crops 



as food producers. 



ROTATIONS. 



The most important work at present in progress at the Central Experimental 

 Farm is the testing of rotations considered suitable for live stock farming. During 

 the past year a re-arrangement was made so that there are now permanently located 

 thirteen rotations varying in duration and treatment. They are being studied, keep- 

 ing in mind the following points of merit: — 



1. Their ability to supply different crops in the proper proportions for 

 certain needs. 



2. Their power to keep weeds in check. 



3. Their comparative profits. 



4. Their effect on the fertility of the soil. 



Owing to the changed location of many of them, and to the fact that it was not 

 possible to have the regular crops grown in every case, aJl of the results for the past 

 year are not being published to show comparisons, nor will they be included in 

 averages that will be compiled in later years. 



The results to date have not been of such a nature as to warrant making state- 

 ments as to the relative effect of the various rotations that we have tried on the 

 fertility of the soil. From a summing up of past investigations and results we would, 

 however, submit, the following rotations, as having given excellent results here, where 

 the object is to supply suitable kinds of feed in the right proportions for live stock 

 raising. 



Rotation ' D.' 



This is of three years' duration and is well suited for intensive dairy farming where 

 soiling crops are used. 



First year. — Corn or other hoed crop. Apply manure during the winter or spring 

 at the rate of 15 tons per acre, shallow plough in the spring for corn (fall plough for 

 roots) turning under manure and clover, work well before sowing. 



Second year. — Grain. Seed down with 10 pounds red clover, 2 pounds alsike, 6 

 pounds alfalfa and 6 pounds timothy per acre. 



Third year. — 'Clover hay, two crops expected. 



Rotation ' C 



An excellent four-year rotation made up of equal areas of hoed crops, grain, hay, 

 pasture. 



First year. — Corn or other hoed crop. Plough previous August, manure 20 tons 

 per acre, work at intervals, and ridge up in fall. 



Second year. — Grain. Seed down with 10 pounds red clover and 10 pounds to 

 12 pounds timothy per acre. 



Third year. — Clover hay, two crops expected. Second crop may be saved for seed. 

 Fourth year. — Timothy hay or pasture.
