Downy
mildew in sunflower: new virulent races
Author: Khalid Y. Rashid, Agriculture
and Agri-Food Canada, Morden Research Station, Morden, MB R6M
1Y5
Summary: The environmental conditions in 2011
were favourable for downy mildew infections at the seedling stage
of the sunflower crop. The most predominant races belong to race-group
700 which are virulent on most commercial sunflower hybrids.
Field-scale
measurements of carbon exchange in cropping systems
Author: Amanda M. Taylor, Dept. of Soil Science,
University of Manitoba, Winnipeg, MB, R3T 2N2
Summary: Over three years, carbon dioxide fluxes
were measured over a perennial pasture and over two annual cropping
systems recently converted from pasture.
CWRS
wheat varieties response to fusarium head blight
Author: Pam de Rocquigny, Manitoba Agriculture,
Food & Rural Initiatives, Carman, MB, R0G 0J0 and Mike Grenier,
Canadian Wheat Board, Winnipeg, MB, R3C 2P5
Summary: To evaluate the effect of Fusarium Head
Blight (FHB) on yield, quality and disease severity of CWRS wheat
varieties with improved FHB resistance.
Measuring
gaseous losses from composting separated solid hog manure-preliminary
results
Authors: Jolene Rutter and Mario Tenuta,
Department of Soil Science, University of Manitoba, Winnipeg,
MB R3T 2N2
Summary: Preliminary results of a LI-8100 automated
chamber system and Fourier Transform Infrared Radiation multi-gas
analyzer for determining the types and quantity of gaseous losses
that occur during the composting of separated solid hog manure.
Reducing
fossil fuel energy use in agriculture
Authors: Martin Entz, Joanne Thiessen Martens,
Keith Bamford, Sarah Braman, Harun Cicek, Rachel Evans, Caroline
Halde, Kristen Podolsky, Dept. of Plant Science, University of
Manitoba, Winnipeg, MB R3T 2N2
Summary: This poster will describe innovative
but attainable possibilities for increasing energy efficiency
in agriculture by reducing energy use by up to 80%.
Improving
canola crop safety using phosphorus and sulphur fertilizers in
the seed row
Author: Laryssa Grenkow, M.Sc. Department
of Soil Science, University of Manitoba, Winnipeg, MB
R3T 2N2
Summary: Conventional and enhanced efficiency
phosphorus and sulphur fertilizers were blended to determine the
effect on seedling damage on canola at Carman and Kelburn, MB
Can
non-targeted application of propiconazole improve malt barley
yield and
quality?
Authors: R.E. Karamanos, N.A., Flore and
J.T. Harapiak
Summary: Non-targeted application of propiconazole
to malting barley cultivars resulted in significant yield increases
and improvement in kernel plumpness that occurred at all nitrogen
rates in a set of 80 experiments conducted in the nineties. The
results of this study indicated that malt barley producers should
not have to vary fertilizer and disease management strategies
to avoid delayed maturity and consequent effects on malt yield
and quality. There was no impact of propiconazole on grain protein.
Economic benefits of non-targeted propiconazole application are
dependent both on the price of propiconazole and malting barley.
Nutrient
deficiency diagnostic training with field and hydroponically grown
crops
Authors: John Heard and Vikram Bisht, Crops
Knowledge Centre, Manitoba Agriculture, Food and Rural Initiatives,
Carman, MB R0G 0J0; Alvin Iverson, Ian N. Morrison Research Station,
Carman, MB R0G 0J0
Summary: For fifteen years the Crop Diagnostic
School has provided field scouting and diagnosis training annually
for 300-400 agronomists at the University of Manitoba research
station near Carman. For the past 7 years nutrient depleted sand
boxes have been used to display deficiencies of P, K and S in
crops of corn, soybeans, sunflowers, canola, wheat, flax and alfalfa.
Micronutrient deficiencies evaded our best efforts to impose them.
In 2010, 4 hydroponic beds were established in the field using
silica sand and with circulation of appropriate nutrient solutions,
deficiencies of Cu, Zn and B were created in wheat, canola, soybeans
and dry beans. Participants at the Crop Diagnostic School earn
CCA continuing education credits through their participation in
this lesson and completion of a quiz.
Showing
how a product “that does nothing” can enhance yields
and replace nitrogen fertilizer
Author: John Heard, Crops Knowledge Centre,
Manitoba Agriculture, Food and Rural Initiatives, Carman, MB R0G
0J0
Summary: At the 2009 Crop Diagnostic School,
the naturally occurring extract from Acer negunda was
applied to crops of wheat and canola. In the canola, the extract
was foliar applied on June 2 to emerged plants in a RCBD design
in 20 separate experiments within the same field to simulate a
number of locations. Biomass yields were taken and analysed using
statistics. In 2 cases the yield of canola was increased statistically.
Likewise in an adjacent wheat field a RCBD experiment compared
wheat with N at 60 lb N /ac plus Acer negunda compared
to 120 lb N/ac fertilizer. Biomass yield and SPAD chlorophyll
readings were statistically similar indicating that Acer negunda
replaced 60 lb nitrogen fertilizer. Results will be presented
and discussed.
What’s
lurking in your canola field?
Authors: Anastasia Kubinec1, Debra McLaren2,
Holly Derksen1 and Vikram Bisht1 1Manitoba Agriculture, Food and
Rural Initiatives, Carman, MB R0G 0J0 2Agriculture and Agri-Food
Canada, Brandon, MB R7A 5Y3
Summary: Canola is one of the most
economically important crops produced in Manitoba. To continue
to grow profitable canola crops, yield reducers such as canola
diseases need to be identified and quantified.
Blackbird
predation in sunflowers
Authors: Claire Kincaid1 and Anastasia Kubinec2,
1National Sunflower Association of Canada, Carman, MB R0G 0J0
2Manitoba Agriculture, Food and Rural Initiatives, Carman, MB
R0G 0J0
Summary: Blackbird damage in Sunflower has been
an ongoing production issue for many years. The severity of damage
is hard to predict and variable within fields. Feeding tends to
be in localized areas of fields close to roosting areas such as
cattails and power lines.
Greenhouse
gas emission benefit of including perennial forage in a Canadian
Prairie cropping system
Authors: Tek Sapkota, Mario Tenuta, Brian
Amiro, Aaron Glenn and Siobhan Stewart,
Department of Soil Science, University of Manitoba, Winnipeg,
MB R3T 2N2
Summary: Emissions of Greenhouse gases from perennial
and annual cropping system were monitored by using micrometeorological
flux gradient method.

Carman, MB R0G 0J0; Matthew Wiens, Agri-Environment Knowledge
Centre, Beausejour, MB, R0E 0C0
Summary: Significant climatic changes are expected
for southern Manitoba by the middle of this century. These projections
and some potential impacts for agriculture are presented.
