TABlE 2 | Cane (TCH) and sugar yield (TSH) of varieties Q151, Q190 A , Q208 A and Q232 A grown on 1.5 m single, 1.8 m single and
1.8 m dual rows near Bundaberg.

At Mackay (Table 3) crops on the
1.8 m single row configuration yielded
significantly less than those on the 1.5 m
single and 1.8 m dual row configurations.
There were variety differences, with
Q190 A performing poorly at the site
but no variety-by-row configuration
interaction. All varieties performed poorly
on the 1.8 m single row spacing.
In the Burdekin (Table 4) no difference
was found between the 1.85 m single
and 1.85 m dual row configurations.

Q151 A
Although large difference in yield were
found between varieties these differences
were not statistically significant, due to
large variation within the trial. The
variety-by-row configuration interaction
was not significant.
All varieties produced similar yield on
the 1.85 m single and 1.85 m dual row
configurations. There was no evidence that
the growth patterns exhibited by Q117
and Tellus A were an advantage on the
dual row configuration.
At Ingham, there was no significant
difference between row configurations
(Table 5). A variety effect was found
due to the poor performance of Q183 A .
The variety-by-row configuration effect
was not statistically significant. All
varieties responded to the different row
configurations in a similar manner.
