92 WHEAT PRODUCTION IN NEW ZEALAND 
The high yield of the strain Al in this its fourth year 
of trial, together with its excellent quality, justified an 
extended trial of the strain. Im 1914, therefore, a field 
of about 25 acres was sown partly with the strain and 
partly with commercial seed. Small lots of seed were 
sent out to two reliable farmers, and the usual half- 
acre plots were sown in the experimental field. The 
following were the results in bushels per acre, the order 
of the figures in each horizontal row representing the 
order of the plots in the fields.

This ended the preliminary trials of the strain. It had 
now been grown and tested against commercial seed 
during 5 seasons, on moderate wheat growing land. It 
had been tested in 11 different plots in 7 different fields 
and on 3 separate farms. The conditions of trial have 
been detailed above, and the results may be tabulated as 
follows, percentages in the earlier trials being translated 
into bushels per acre on the yields of the other parts of 
the field in which the small plots were grown.

This increased yield, together with obvious superiority 
in milling quality, appeared to warrant the College 
authorities in putting the seed of the strain upon the
