Continuous Growing of Barley.

halves and single dressings on May 15. Although no result 
was expected so early from the use of lime it certainly did 
appear as if that put on plots 2aa and 5aa had caused some 
improvement. Heavy rains early in May affected the plant 
considerably, as did also an attack of wireworm ; this latter 
was least marked on the rape cake plot (10b). The barley 
came into ear by June 19, and the several plots were cut 
August 25-26 and carted on September 1, the crop, however, 
being much damaged by rain, which fell heavily on August 
28-29. The corn was threshed out on November 3, and 
subsequently valued. 
The crop, though much damaged in regard to quality by the 
rains that fell at harvest time, was a much heavier one than 
that of 1904 and was not much below the average of the first 
twenty years. Thus, the unmanured produce was 19‘35 bushels 
per acre as against the average of 21 bushels, and mineral 
manures alone gave 23 - 3 bushels (average 22‘5 bushels). 
Farmyard manure, as with the wheat, produced the heaviest 
crop, viz., 42*6 bushels, while 40‘6 bushels were reached with 
a dressing of artificials comprising mineral manures, ammonia 
salts, and lime (plot 5b), no lime, however, having been put 
on since 1897 ; while ammonia salts alone gave no crop, the 
same with lime (1897) but no minerals yielded 23’7 bushels, 
or in excess of the produce from nitrate of soda alone (17*9 
bushels). Even when used with minerals (plot 6) nitrate of 
soda failed to give as good a crop as did ammonia salts with 
minerals and lime (30 bushels as against 40’6). Rape cake 
produced the satisfactory yield of 34 bushels. In regard to the 
newly limed plots it may be noted that, though so recently 
applied, the 5 cwt. on plot 2aa produced nearly 10 bushels 
of corn w r here before none had grown, and on plot 2bb an 
increase of bushels. On plot 5aa, however, where 1 ton had 
been applied, no benefit accrued. The crop returns and other 
particulars are set out in Table II., page 285. 
The quality of the corn was much deteriorated owing to 
the unfavourable conditions ruling at the time of harvest. 
As with the wheat, so here, farmyard manure gave the highest 
produce and the best quality, while nitrate of soda gave the 
worst quality of all. 
As had been the case with the wheat, the lowest weight 
per bushel was given with nitrate of soda (plots 3 and 9), and 
the best with ammonia salts (and lime), rape cake, and farm- 
yard manure. The best samples were not more than would 
pass as low class malting barleys, for which, however, owing 
to high prices ruling for foreign barleys, there was at the time 
a good demand, and so the differences in price are not so 
marked as otherwise would have been the case.
