I continued to travel
south down state highway 1 and meet up with an old friend who I worked with in
Western Australia 16 years ago who runs a gorse spraying business in Waimate.
It was great to catch up and see him again. We had a drive around the area and
saw some farmers harvesting oilseed rape, we stopped by and I arranged to visit
the farmer in the morning.

I visited Hugh Wigley the next morning, I wanted to talk to farmers in this
area as it was a dryland area, ie no irrigation. Hugh was farming 1100 acres of
wheat, barley, oilseed rape and ryegrass, the ryegrass was the most profitable
crop, and 90 % of the grain would need to be dried. The similarities to the Uk
were apparent, so how do their crop yields compare to the UK? Average wheat yields were 8.5 T/Ha, which is
very similar to home, this was reassuring after talking about yields of 15T/ha
and wondering what we have been doing wrong. It also validated my thoughts that
being able to control the water available to a crop through irrigation leads to
a huge uplift in yield potential. Especially as the general agronomic husbandry
is very similar except lower amounts of nitrogen and less fungicides are
applied, because the nitrogen utilisation is lower in a dryland situation and
also the later T4 fungicide is generally not needed as the crop is starting to
naturally ceness rather than being kept alive by a late irrigation.

Having said this there was a centre pivot irrigator installed
in the centre of Hugh’s farm, this was more as a strategic investment than an
immediate need. It was the last time that water would be made available in the
area and it could lead to more options in the future. It was only used to apply
30mm this season, compared to over 200mm
further north in Mid Canterbury.
Hugh burnt all his wheat straw as there wasn’t a demand for
wheat straw, it helped with grass weed management and also reduces time and
horsepower required to run the farm. Only 2 small (110hp and 130hp) tractors
were used to establish all the crops.
Hugh had various ways to dry the grain, from flat stores to
silos with stirrers, and also a truck with a drying floor. The truck would be
loaded up in the winter time and warm air blown through the false floor until
the grain was dried. It was an example of how Kiwi farmers have learnt to be
resourceful simply because New Zealand is so far from other parts of the world.
