The Woburn Field Experiments , 1908. 343 
Rotation Experiments (Stackyard Field). 
This experiment, it will be remembered, is divided into 
two halves, viz. : — 
A. The upper half, in which sheep feed off the roots on 
the land, receiving, on one plot, decorticated cotton cake, on 
a second plot, maize meal, and on the third and fourth plots, 
neither cake nor corn. 
B. The lower half, in which the roots are manured with 
dung made in the feeding boxes by bullocks consuming, in 
addition to other foods, for plot 5, decorticated cotton cake, 
for plot 6, maize meal, for plots 7 and 8, neither cake nor corn. 
The object of the experiment is to see what increase of 
crops during the rotation is obtainable from the use of decorti- 
cated cotton cake as compared with maize meal, or from either 
as compared with no cake or corn ; in other words, to ascertain 
what is the unexhausted manurial value of these foods, accord- 
ing as they may be, in the one case, fed direct on the laud by 
sheep, or, in the other case, used by bullocks in feeding boxes 
for the production of farmyard manure. 
A. — upper half (Sheep-feeding). 
Rotation I. 1908, Wheat — following Mustard (1907). 
The mustard stubble was ploughed up in October, 1907, 
and wheat — “ Square Head’s Master ” — drilled, at the rate of 
9 pecks per acre, on November 6. The wheat was rather 
“ patchy ” at first, but was brought on well by the warm 
weather of July, 1908, the crop being cut on August 12 and 
carted on August 26. The results are given in Table III.

The produce was by no means a good one, but it will be 
seen that there was little to choose between the four plots, 
indicating that there was little difference of manurial value 
between the foods used, so far as this, the third crop in the 
rotation, was concerned. The wheats were considered good
