124 Report on the Field and Feeding Experiments at Wohurn. 
The rotation barley, it wiil be seen by the foregoing tabulated 
results, produced a good crop. 
As far as appearances went the barley on the cotton-cake plot 
(No. 1) looked the best and most promising throughout the 
growing season, and the results of the weighings showed that 
on plot 1, on which mangolds, manured with cotton-cake, were 
fed off by sheep, produced about 5J bushels more corn and 
about 1 cwt. more straw than the barley on the maize plot (2). 
It will further be seen that nitrate of soda on plot 3 did not 
yield quite so good a crop as plot 1, manured in the preceding 
season with dung made from decorticated cotton-cake. The 
barley crop on the nitrate of soda plot weighed 1 lb. less per 
bushel than the barley on the cotton-cake plot and produced 
2 cwts. 7 lbs. more straw. 
There was evidently more active growth on plot 3 than on 
the other plots, and had the weather at harvest-time been warm, 
instead of cold and wet, the nitrate of soda plot (3) probably 
would have yielded the heaviest return in corn. In wet and 
cold seasons nitrate of soda is apt to produce too much straw 
and rather inferior barley. 
On the whole, the rotation barley in 1880 was a fair crop and 
afforded evidence of the superior fertilising properties of decor- 
ticated cotton-cake in comparison with maize-meal. 
Rotation No. 2. — Four acres. 1877, mangolds ; 1878, barley; 
1879, seeds; 1880, wheat. 
Wheat, 1880.— The seeds were fed off in 1879 by sheep. 
On plot 1 the sheep consumed as additional food 672 lbs. of 
decorticated cotton-cake. On plot 2 they consumed 728 lbs. of 
maize-meal. On plots 3 and 4 no additional food was given, 
but on plot 3 the wheat was manured with artificial manures, 
containing as much nitrogen and other fertilising constituents 
as the manure from 672 lbs. of decorticated cotton-cake, namely, 
275 lbs. of nitrate of soda, 73 lbs. of bone-ash (made into super- 
phosphate), 45^ lbs. of sulphate of potash, and 47^ lbs. of sulphate 
of magnesia. 
And lastly, on the fourth acre (plot 4) the wheat was manured 
with artificial manures, containing as much nitrogen and other 
fertilising constituents as the manure from 728 lbs. of maize- 
meal, namely, 58^ lbs. of nitrate of soda, 11 J lbs. of bone-ash 
(made into superphosphate), 5 lbs. of sulphate of potash, and 
8 lbs. of sulphate of magnesia. 
The sheep came off the land on the 5th of November, 1879, 
when the land was ploughed and got ready I'or wheat-sowing, 
which took place on the l8th of November, 1879, when also the 
mineral manures were sown broadcast. 
The nitrate of soda was applied on the 24th of March, 1880.
