EXPERIMEXTAL FARMS

below the average. Straw was short, but the oats filled fairly well and harvested a 

 good yield of grain. Turnips made steady progress, while mangels and corn made 

 remarkable autumn growth, and all yielded up to the average for the Farm. Potatoes 

 orodueed a bumper crop of good quality. 



COST OF PRODUCTION OF FIELD CROPS. 



The following table summarizes the costs of producing mangels, corn, oats, and 

 hay in 1914 : —

ROTATION OF CROPS. 



The results of experiments with croj) rotations indicate the importance of the oixler 

 in which crops are grown. A good rotation may be said to include hoed, grain, and hay 

 crops which, for best results, should be grown in the order named. The duration and 

 cultural treatment of the rotations, however, may be varied to suit different conditions. 

 The following rotations are now in operation here, any one of which should prove satis- 

 factory for ordinary farm conditions. 



Eotation "A" (five years' duration). — Hoed crop, manured. Grain, seeded down 

 with clovers and grass. Olover hay, top dressed wit'h manure in autumn. Timothy hay, 

 field ploughed in August, top worked and ribbed up in October. Grain, seeded down 

 with red clover to be ploughed under the following spring, when the succeeding hoed 

 crop is corn. 



Rotation " B " (five years' duration). — Hoed crop, manured. Grain seeded down 

 with clovers and grass, seeds top dressed with manure in autumn. Olover hay, ploughed 

 in avitumn. Grain seeded down with clovers and grass. Olover hay. 



Rotation " C" (four years' duration). — Hoed crop, manured. Grain, seeded down 

 with clover and grass. Clover hay, timothy hay, field ploughed in August, top worked ^ 

 and ribbed up in October. 



Rotatipti "D" {three years' duration). — ^Hoed crop, manurecj. Grain, seeded 

 down with clovers and grass. Clover hay. 



Soiling Crop, Rotation " R" {three years' duration). — Corn for early fall feed, 

 manured. Peas and oats to cut green, seeded down with clovers and grass. Clover 

 hay, to cut green. 



Some characteristics of the above rotation, desirable under almost any conditions, ■ 

 are as follows : — 



(1) Grain fields are always seeded down with clover, even though it be used only! 

 as a fertilizer, as in the case of the fifth year of rotation " A." 



(2) Grass and clover seedings are heavy. Increased crops of hay and rare failures 

 of a catch have justified them.
