Report on the Field and Feeding Experiments at Wohwm. 243 
Rotation No. 3. — Four acres. 1878, seeds; 1879, wheat; 
1880, mangolds; 1881, barley; 1882, seeds; 1883, wheat: 
1884, swedes.- 
Barley, 1885. — The swedes grown in 1884 were pulled up on 
November 21st and following days, and weighed. The roots 
were fed off by sheep with only chaff as additional food, and the 
land was ploughed up afterwards. It was harrowed and rolled 
early in March, and on March 17th 8 pecks of " Golden Melon " 
barley per acre were sown. The barley came up well and strong, 
and was hoed and harrowed in May. Seeds were not sown 
among the barley, as had been done in the previous rotation. 
The previous swede crop of 1884 had been manured per acre 
as follows : — 
Plot 1. — With dung, made from 1880 lbs. straw as litter ; 5000 Vas. 
mangolds ; 1250 lbs. wheat-straw chaff, and 1000 lbs. decorti- 
cated cotton-cake. 
Plot 2.— With dung, made from 1880 lbs. straw as litter ; 5000 lbs. 
mangolds ; 1250 lbs. wheat-straw chaff ; and 1000 lbs. of maize- 
meaL 
Plot 3.— With dung, made from 1880 lbs. straw as litter ; 5000 lbs. 
mangolds; 1250 lbs. wheat-straw chaff ; and artificial manure, 
containing two-thirds as much nitrogen, and other consti- 
tuents, as the manure from 1000 lbs. decorticated cotton-cake ; 
namely, 248 lbs. nitrate of soda, 100 lbs. of bone-ash (made 
into superphosphate), 62j lbs. sulphate of potash, and 65 lbs. 
sulphate of magnesia. 
Plot 4.— With dung, made from 1880 lbs. straw as litter ; 5000 lbs. 
mangolds ; 1250 lbs. wheat-straw chaff ; and artificial manure, 
containing as much nitrogen, and other constituents, as the 
manure from 1000 Ibr. maize-meal ; namely, 80 lbs. nitrate of 
soda, 16i lbs. bone-ash (made into superphosphate), 7 lbs. 
sulphate of potash, and 11 lbs. sulphate of magnesia. 
No further manure was applied to any of the plots, except 
plot 3, to which nitrate of soda, to make up the remaining one- 
third of the nitrogen equivalent to that in the manure from 
1000 lbs. of decorticated cotton-cake, was applied as a top- 
dressing on May 7th. As the barley-crop ripened, it appeared 
to be a splendid crop. No. 3 looking, if anything, the best. It 
was cut, tied, and stacked, on August 19th, and carted on the 
20th. The results are given in Table III., p. 244. 
The fact that such heavy yields of barley, as heavy, in fact, 
as the highest produce of the plots 8a and 9a in the Continuous 
Experiments on Barley, could be grown even on the maize-meal 
plot and its equivalent in artificials, affords strong confirmation 
of the view entertained that the land is, by previous manuring, 
already so rich as to be able to produce a maximum crop, with 
the addition of maize-meal, so that the superiority of decorti- 
cated cotton-cake has not had an opportunity of showing itself.
