SPRING BARLEY SURPRISE
With sugar beet and late-harvested Brussels sprouts
in the rotation, Norfolk cereal grower Jeremy Hancock has to have
some spring barley in his cropping line-up, accepting its lower
yield potential out of necessity. But to his great surprise and
delight last year’s (2002) spring crop of newly recommended
euro-malting barley, Prestige outyielded his winter barleys by a
handsome margin. And this despite being grown on his poorest land.
“Until about 10 years ago we grew malting types,
such as Triumph, but the legacy of high nitrogen residues from previous
beet, vegetable and pea crops made this an unacceptably risky business,”
explained Mr Hancock who farms 320ha (800acre) White House Farm
at Fring near Docking.
As well as 38 ha (95 acres) of spring barley the cropping
on the light-land farm includes 68ha (170 acres) of Maris Otter
and Fanfare winter barley, 56ha (140 acres) of Claire and Equinox
winter wheat, 48ha (120 acres) sugar beet, 36ha (90 acres) of Brussels
sprouts, 24ha (60 acres) of marrowfat peas, and some cabbages.
“Even with no applied fertiliser our spring
barley used to suffer from the residual N, so rather than risk ending-up
with low priced feed crops, we decided to add value by growing it
for seed,” he pointed out. “With current prices, a 2.25t/acre
(5.6 t/ha) crop of feed barley would give us no profit. However,
a seed crop provides a workable margin.
“We grow winter malting barleys because grain
N levels don’t pose problems two years after the peas in our
rotation. We also choose varieties with malting potential for our
spring crop. This means that, nitrogens permitting, we have a safety
net if a crop fails to meet seed contract specifications.
“We used to grow Optic in the spring slot, but
last year we switched to the variety making such an impression on
the continent, Prestige. “Optic didn’t do us badly in
2001 at 2.25-2.4 t/acre (5.6-5.9t/ha). But it never seemed to yield
as well as it should, mainly because we lost so many ears before
the combine could get in. I reckon we were easily losing as much
as 0.5t/acre (1.2t/ha).”
The White House Farm Prestige followed sugar beet on two fields.
On one the sugar crop was cleared in reasonable time, but the harvester
only moved out of the other on March 4 – two months later
than ever before.
After ploughing the easy-working free-draining soil
soon dried out though and, following his grand-father`s advice not
to sow too soon, Jeremy Hancock drilled the variety at 154kg/ha
(140lbs/acre) into a reasonable seedbed after the Cheltenham Festival,
between March 16 and 23. The crop came through very quickly and
impressed from the outset.
“I’ve never seen spring barley look so well in early
April. It had a good colour and was full of growth and vigour. By
early May it was obvious it would yield well so I decided we could
afford to give it an extra 20 units of N to take the overall amount
to 100 units/acre.
“We mixed manganese sulphate with the first
fungicide treatment on May 15 and went in the following day with
a wild oat herbicide. We applied a second fungicide in mid-June
to mop up any remaining mildew and Rhynchosporium.”
Under this regime, the crop stood up to the summer
storms with no sign of lodging whatsoever, and was ready for harvesting
at about the same time as the wheat in mid-August. This worked well
as the barley was combined in the mornings while Mr Hancock waited
for the wheat to dry out.
“When we combined the Prestige I was amazed
how quickly the grain tank filled up,” he said. “It
was clear we had a heavy crop on our hands. In fact, we averaged
2.75 t/acre (6.8 t/ha) from the lightest land on the farm, having
never got more than 2.25t/acre (5.6 t/ha) from this field in the
past.
“This was a superb result. Not only did the
variety give us 0.5t/acre (1.2 t/ha) more than our previous best
spring barley crop, it even out-yielded the winter barleys we grew
on better land. Last season`s Fanfare did 2.5t/acre (6.1t/ha) while
the Otter gave us 2t (4.9 t/ha).”
Jeremy Hancock was also delighted with the sample
off the combine - big and bold grain with an attractive colour.
Subsequent analysis showed a high specific weight, just 3% screenings
and 98% germination.
“With the right quality to meet European brewers’
needs, it’s clear Prestige has a big future as malting barley,”
he concluded. “I shall certainly be growing it again this
year. And if it performs as well for other growers I can see it
taking over as the UK`s favourite malting barley in pretty short
order.”
