Report on the Field and Feeding Experiments at Wubarn. 355 
Plot 2. — "With dung, made from 1350 lbs. straw as litter; 5000 lbs. 
mangolds ; 1250 lbs. wheat-straw chaff, and 1000 lbs. of maize- 
meal. 
Plot 3. — "With dung, made from 1350 lbs. straw as litter ; 5000 lbs, 
mangolds; 1250 lbs. wheat-straw chaff; and artificial manure, 
containing two-thirds as much nitrogen, and the other consti- 
tuents, of the manure from 1000 lbs. decorticated cotton-cake ; 
namely, 248 lbs. nitrate of soda, 100 lbs. of bone-ash (made 
into superphosphate), 62 1 lbs. sulphate of potash, and 65 lbs. 
sulphate of magnesia. 
Plot 4. — "With dung, made from 1350 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 lbs. maize-meal ; namely, 80 lbs. nitrate of 
soda, 16? lbs. bone-ash (made into superphosphate), 7 lbs. 
sulphate of potash, and 11 lbs. sulphate of magnesia. 
For the succeeding barley in 1883 no artificial manure was 
used on plots 1, 2, and 4 ; and on plot 3 only the remaining 
one-third of the equivalent of nitrogen in the manure from 
1000 lbs. of decorticated cotton-cake, the other two-thirds 
having been already applied to the swede crop. 
The barley, though coming up well in May and June, 
suffered severely from the heavy rains and storms of July, 
even more so than the wheat crops. It was much beaten down 
and storm-twisted, plot 3 especially showing this very markedly 
— this continued throughout July. On my visit of August 3rd, 
1 found that no great difference was noticeable in any of the 
plots, and that on all of them the barley had gone down more 
or less. The barley was cut on August 21st and following 
days, and carted and stacked on September 4th, 6th, and 7th, 
all being got in in good condition. It was threshed in the field 
on October 24th and 25th ; and the corn, after a short storing 
in the granary, was winnowed, measured, and weighed on 
October 31st, the results being given in Table V. (p. 356). 
In every case the yield of corn was more than that of 1882, 
plot 1 showing this the least, while the other three gave a very' 
large increase, amounting in the case of plots 3 and 4 to one- 
third of the total yield of 1882. There was but little difference 
in the amount of straw. The largest crop was obtained from 
the maize-meal plot, while the decorticated cotton plot, which 
had in 1882 given the best results, was now the poorest of all four. 
In fact, the decorticated cotton-cake plot now gave even a poorer 
yield than the unmanured plot 4, which had been fed off by sheep, 
receiving no purchased additional food — thus reversing exactly 
the results of last year as regards the two plots 1 and 2. The 
all effects noticed last year on plot 3, by the top-dressing of 
nitrate of soda, were not repeated in this year's experience.
