Report on the Field and Feeding Experiments at Wohurn. 145 
The four acres of Rotation wheat were cut on the 13th of 
September, or just about one month later than in 1878, carted 
and stacked on the .'h'd and 4th of Octoljer, and threshed out in 
the field in the beginning of November 1879. The straw and 
chaff were weighed in the field at the time of threshing, and 
the corn was kept in labelled bags until the 19th of November, 
when it was weighed, and the total weight checked bj measuring 
the number of bushels, and weighing each bushel. 
The table on page 14G shows the results obtained. 
Nothwithstanding the distressing season, the wheat on all the 
four Rotation acres, it will be seen, produced a full crop. 
Throughout the season the wheat looked splendid, and promised 
a very heavy crop, but towards harvest it became evident that 
the corn would not come to perfection for want of sun and heat. 
There is not much difference in the yield of corn on each of 
the Rotation acres, nor does the bushel of wheat differ much, 
whether grown with or without artificials. The corn was light, 
weighing only from aoj lbs. to 54^ lbs. per bushel. Nitrate of 
soda applied as a top-dressing on plot o in a proportion equiva- 
lent to the nitrogen contained in the manure resulting from the 
consumption of ^72 lbs. of decorticated cotton-cake on plot 1, 
produced only 1^ bushel more head-corn and a few pounds 
more tail-wheat than the wheat on plot 1 ; whilst the smaller 
dose of nitrate of soda used as a top-dressing on plot 4, con- 
taining an amount of nitrogen equal to that of the manure 
resulting from the consumption by sheep of 728 lbs. of maize- 
meal, yielded about 2 bushels more head-corn than the wheat on 
plot 2 (the maize plot). 
On looking carefully over the tabulated results (p. 146) it will 
be noticed that the application of nitrate of soda on plots 3 and 4,, 
and more especially on plot 3, resulted in a very large quantity 
of straw. On all four acres, I would remark, more straw and 
less corn were produced in 1879 than in 1878 ; but, as the 
wheat was very strong, the four Rotation acres would have 
yielded very heavy wheat crops if sunshine and heat had brought 
the corn to perfection. 
On plot 3, it will be seen, no less than 3 tons 4 cwts. 18 lbs. 
of straw and chaff were produced, or about 11 cwts. more than 
on plot 1 (cotton-cake plot). The cost of the artificial manures 
used on plot o amounted to 2/. 18s., and on plot 4 to lis. 
Rotation No. 4. — Four acres: 1878, roots; 1879, barley; 
1880, seeds ; 1881, wheat. 
Barley, 1879. — The mangolds in 1878 were grown on : 
Plot i. With dung, made from 1728 lbs. of straw as litter, 
5000 lbs. mangolds, 1250 lbs. wheat-straw chaff, and 1000 lbs. 
of decorticated cotton-cake.
