Dr Bob Bulmer (Hutchinsons Trials and
Research Manager) reviews results
from the latest season at our crop
development sites around the country.

Winter Wheat
Although semi-arid conditions prevailed in Spring and
Summer, the yields at most of the development sites were
good this year. The response to fungicide and plant growth
regulator was lower than the previous three years but still
significant. The percentage of theoretical yield can be used
to give an indication of crop performance. These yield
percentages across the years are average to good, so there
is obviously room for further improvement.
Compared to site variation, there was less variation in
variety yields - the highest yielding treated variety was
Bennington 11.24 t/ha and the lowest yielding variety was
Basset 9.81 t/ha. All of the varieties responded positively to
fungicide and plant growth regulator inputs.

Data from Grayingham, Little Ponton, Stowbridge, Morton-on-Swale, Alnwick and Ludlow
There was considerable variation from site to site this
year reflecting the influence of the dry weather and the
different soil types. There was a yield difference of 6.29t/ha
comparing the highest yielding site Ludlow 13.83t/ha with
the lowest yielding site Little Ponton 7.54. Despite a lack
of rainfall, three other sites Harleston, Great Tew and Stow
Bridge produced yields over 12.5t/ha.
Comparing the different groups, Group 4 soft varieties had the
highest yields 11.34 t/ha with Group 4 Hard varieties the lowest
yields 10.87 t/ha although there was only a small difference
of 0.47t/ha between the two groups, which is probably not
significant. This chart illustrates the challenge of achieving
high protein levels from the high yielding milling varieties.
