Table IV. — Yields of nine varieties of Australian and three other important varieties of 
wheat compared with the White Australian variety, as grown in plat experiments at the 
Plant Introduction Station-, Chico, Calif, during the 10-year period from 1910 to 1919, 
inclusive.

During the 10-year period from 1910 to 1919 White Australian 
yielded at the rate of 35.4 bushels per acre. In the same period 
Early Baart had an average yield of 37 bushels. The increase 
over White Australian is due to the abnormal yield in 1911 of 90.6 
bushels. The average difference of 1.7 ±2 bushels, representing 4.7 
per cent, is not a significant increase. On the other hand, no other 
Australian or commercial variety shown in Table IV outyielded 
White Australian. Five Australian varieties were grown for three to 
seven years and were discarded because they did not yield as well as 
White Australian. Pacific Bluestem, during the eight years 1912 to 
1919, inclusive, yielded a half bushel less. During the two years, 1918 
and 1919, the Bobs variety, which yielded well at Moro, Oreg., had a 
yield significantly less than White Australian. This is also true of 
the Sonora variety during an 8-year period. The red wheats, both 
Marquis and Kharkof , also have yielded less than White Australian. 
The farm practice in the Sacramento Valley of growing White 
Australian as the principal commercial variety and the introduction 
of Early Baart are in accord with the experiments at the Plant 
Introduction Station. The better milling quality of Early Baart as 
compared with the White Australian variety was a sufficient reason 
for establishing the former variety commercially, even though the 
two varieties were only equal in yield. This would have been 
attempted several years before had it not been for the rather weak 
straw of the Early Baart variety and its tendency to lodge when 
grown on heavy or well-fertilized soil and under a heavy rainfall.
