288 Report on the Field and Feeding Experiments at JVohurn. 
very low over all the plots — lower, indeed, than has been 
recorded since 1880. The unmanured plots yielded 12 '2 and 
14*5 bushels per acre respectively, as against 21 "3 and 21*9 
bushels last year ; while the highest yields only amounted to 
34*8 bushels on plot 8 B, and 33 "9 bushels on plot 9 B, the 
corresponding plots in 1885 having produced 41 • 1 and 40 
bushels. Nitrate of soda, as compared with ammonia-salts, has 
produced the better results, 17*0 bushels being given by 200 lbs. 
of ammonia-salts to the acre, when used alone, as a top-dressing, 
and 20 • 2 bushels by an equivalent amount of nitrate of soda. 
Used in conjunction with minerals, ammonia- salts in the same 
quantity raised the yield to 21 "7 bushels, and nitrate of soda to 
30*8 bushels. When both salts were used in double these 
amounts, and with minerals as before, the increase with am- 
monia-salts was 34 "8 bushels, and with nitrate of soda only 
33*9 bushels; in the case of the latter, however, there was 
more straw. Mineral manures alone only gave a slight increase, 
viz., to 15 * 2 bushels. As in previous years, omission of 
ammonia-salts or nitrate of soda for a single season reduced the 
produce virtually to the yield of the unmanured plots. The 
influence of farmyard-manure, applied at the rate of about 
4 tons to the acre, was hardly perceptible, though, put on at 
the rate of about 8 tons to the acre, it gave 27*9 bushels. 
Where dung was last applied in 1881 the produce was 
16 bushels only. 
Experiments on the Continuous Growth of Barley. 
The plots were forked and prepared for ploughing in the 
middle of September, 1885. The dung for plots 10 B and 11 B 
was made by four 3-year-old bullocks, at the same time and in a 
similar manner to that in which the dung for the wheat plots 
was made, the same amount and kinds of food being consumed 
during the twenty-one days of experiment. The weights at 
the commencement and end were as follows : —
