The Wohurn Field Experiments, 1914. 



as between feeding corn and feeding cake on the land. The 

 following summary enables such a review : — 



It will tlius be seen that in no case has the produce from 

 the cake-feeding exceeded that of the corn-feeding, a result 

 quite contrary to that which would have been expected. In 

 seeking for an explanation, the only untoward circumstance 

 that I can call to mind is that in 1910, when the root crop was 

 fed on, the corn-feeding was done in dry, favourable weather, 

 while when cake was being fed on there was much wet and the 

 land was left in a bad condition and did not plough up nearly 

 as nicely for barley as was the case on the corn-fed plot. How 

 far this may have influenced the succeeding barley crop it is 

 hard to say, but one would have thought that any inequality 

 due to this wonld have righted itself by the time the wheat 

 crop came round. Yet tliis was not so, for, again, the crop 

 was heavier after the corn-feeding. 



Before one is justified in concluding that corn-feeding is 

 just as good as cake-feeding, it is clear that repetition of the 

 experiment is necessary, and this is being carried out on Series 

 D, and will be continued on Series C also for another four- 

 course rotation. 



(b) Series D. 1912, Swedes fed on by sheep with Corn and 

 Cake respectively ; 1913, Barley ; 1914, Green Crop {Mustard). 



After the barley crop of 1913 was removed, the first 

 ploughing of the land took place in October, 1913, and the 

 second ploughing on May 8-13, 1914. On May 23, mustard 

 was drilled at the rate of 10 lb. per acre. A fair, but not large, 

 crop was obtained, the drought telling against its growth. 

 Sheep wei*e put on the land and fed the mustard from July 

 21-30. On August 8, a second drilling of mustard was made, 

 but the crop never grew to any size to make it sufficient for 

 feeding on. It was accordingly ploughed in in October, 1914, 

 and wheal subsequently sown.
