MPGA Soybean Inoculation Trials Prepared by Tone Ag Consulting
Ltd.November 2013 2
1 Executive Summary
In 2013, 10 field scale soybean trials (Table 1) were set up.
These were to determine what effectthere would be on yield if only
liquid inoculant on the seed was used instead of both liquid
andgranular inoculant. There were 10 fields that were selected for
the soybean on-farm trials acrossEastern Manitoba and they were
seeded between May 16th and June 4th. These fields had aprevious
history of soybeans of at least 2 years, with the exception of one
field that has only hadone year of soybeans.
Seeding rates ranged from approximately 150,000 seeds/acre to
246,000 seeds/acre with rowspacing from 7 to 22 inches. There were
three planters and seven air drills used to plant thesoybeans. In
the trials, the farmer applied both his normal rates of liquid and
granular inoculant(ranged from 5-8 lbs/ac) on 6 field-length strips
(With), alternating with 6 strips of only liquidinoculant on the
seed (W/O). Please note that the Sperling-W trial had only 6 strips
in total.
The following is a summary of the results:
1. The trial results (Table 1) showed an average 0.5 bus/acre
yield advantage for the strips withboth granular and liquid
inoculant. Three out of ten trials showed a statistical
significance infavor of using both inoculants at a 95% confidence
interval.
2. The cost of granular inoculant is $11.50/acre (average cost
of 5 lbs/ac of granular). The yieldadvantage for using both
inoculants is not economically significant with soybeans at
$12/bus.This would result in a $6/acre loss. The trials show that
there would be only an economicreturn of using granular inoculant 3
out of 10 times (30%).
3. Soybean yields ranged from 24 to 47 bus/acre across the
trials. The yield difference betweenthe two treatments ranged from
–0.5 to 3.0 bus/acre. Four of the top five yields came fromfields
that had soybeans planted on soybeans.
4. Nodulation counts were done at the V3 and R2 stage.
Nodulation was higher in strips with bothinoculants at the
Blumenort-R and Sperling-W sites. The fields with soybeans planted
onsoybeans had high nodulation in both treatments. Teulon-W had
only had one year of soybeanhistory yet showed the highest
nodulation and had the highest yield across the trial (Figure
1).
5. Soil N, P, and K levels had no correlation with yield and
nodulation and there were no manuredfields in this trial. Rainfall,
soluble salts and carbonates were high on Beausejour-B,
whichresulted in iron chlorosis throughout the field.
6. For this year, there seemed to be no correlation between
yield and rainfall, even when lookingat the crucial period of R4
(pod is .75 inches long at one of four uppermost nodes) to R6
(seedfills pod at one of four uppermost nodes).
7. Diseases were low this year and consisted of fusarium and
phytopthora root rot, alternaria andseptoria leaf spot, bacterial
blight and downy mildew. Insects consisted of mainly
grasshoppersand damage was low to high, with Silver Plains-N and
Blumenort-R spraying insecticide.
Probability for break-even economic return is 30% (at a soybean
price of $12.00/bushel andgranular inoculant at $11.50/acre
(average cost of 5 lbs/ac of granular).
There will be another two years of on-farm research to determine
if using granular inoculant onsoybeans provides an economic
return.

2 Background
Soybean acres in Manitoba have increased to about 1.08 million
acres of soybeans in 2012 fromless than 800 acres in 1996 (MAFRI).
With this increase in acres comes interest in the bestmanagement
practices to ensure sustainability of the industry and
profitability for farmers. There isa need for an organized on-farm
collection of quality data to learn what is profitable and what
isn’t.In discussions with farmers, it appears that inoculation is a
priority.
There were 10 soybean farmers who set up strip trials across
their fields in Eastern Manitoba.These 10 fields were set up to
obtain data on inoculation. The 10 fields were seeded between
May16th and June 4th. There were usually 12 strips across the
field. There were 6 alternating strips withthe farmer’s normal
application of liquid and granular inoculant and 6 strips that
contained onlyliquid inoculant on the seed. There were 3 planters
(2 John Deere and 1 Case) and 7 air drills (Table2). The fields
were usually about a ½ mile long and the strips 40 to 80 feet in
width depending onwhat was needed to take a ‘pure’ combine swath.
This resulted in about 2.4 to 4.8 acres in a stripor from 30 to 50
acres in a trial (See Appendix 1 for Airphoto maps). Information on
individualtrials is located in Appendices 2 and 3.
The soybean seeds have been put under a 3-minute soak test to
see the percentage of seeds thatcrack. These percentages range from
approximately 5-46% (Table 2), with the lower number thebetter
result. Anything below 10% is considered acceptable for percent of
cracks. Plantpopulations (Table 3) were taken on same 10 foot
strips in each strip at first trifoliate and pre-harvest.

3 Observations
Yield Difference:
Table 1 and Figure 1 gives a summary of yields on the 10 trials.
The average seeding rate acrossthe trial locations was 196,000
(Table 1). Neither total rainfall nor rainfall from July 22 to
August31 (R4-R6 stage) appears to correlate with yield (Table 1,
Figure 1 and Figure 2). Full pod stage(R4) started July 22 in the
trials. Please note the Teulon-W trial only had one year of
soybeanhistory but showed no difference in nodulation.
There was a 0.5 bus/acre advantage for using both inoculants
across the trial locations. Three outof the ten trials showed a
statistical significance in favor of using both inoculants at a
95%confidence interval. The remaining locations are not
statistically significant (Appendix 3).
Looking at the results from this year’s data, there was an
economical advantage for using bothgranular and liquid inoculants 3
out of 10 times (30%).
The R4 stage (pod is ¾” long at 1 of 4 uppermost nodes on the
main stem with a fully developedleaf) was reached about July 22,
2013 and lasted until August 31, 2013 on most of the trials.

Rainfall/Yield:
The yield difference was 0.5 bushels higher for the strips with
both inoculants. Yields ranged from27 to 47 bushels/acre. There was
no correlation between total rainfall or R4-R6 rainfall and
yield(Figures 1 & 2). Rainfall was fairly uniform during the
season.

Ground Cover/Yield:
Table 2 shows the soil types ranging from clay to very fine
sandy loam. The Ag Capability rangedfrom Class 1 to 5. The
varieties ranged from short to long season. The percent ground
cover wastaken at row closure between July 9-26. There was a strong
relationship between ground cover andyield (Figure 3). The percent
crop residue cover on the fields was also done and showed
nocorrelation with overall yield. This may be different in
cooler/wetter springs where higher residuecover could have an
impact on plant emergence and yield (Table 4). There was no
relationshipbetween yield and row spacing.

Soil Fertility & Nodulation/Yields:
Soil tests were done in spring after seeding (Table 3). There
was very high soil Olsen P levels atTeulon-W (17 ppm). There were
low P levels at Beausejour-H (5 ppm) and Blumenort-R (6 ppm).No
sites have a history of manure. Since P levels were below 20 across
all trials, it is difficult todetermine whether there would have
been any effect on yield. Results from last year’s populationtrials
show there is a yield benefit from P values about 20 ppm.
The soil analysis (Table 3) shows soil nitrogen ranging from
20-136 lbs/acre. Even at 136 lbs/acreN, St. Andrews-K still had
good nodulation (10-20 nodules/plant) across the trial. All trials
hadgood to excellent nodulation between the two treatments. The
highest nodulation came from fieldswith soybeans planted on soybean
stubble. Only Sperling-W and Blumenort-R showed a differencein
nodulation between the two treatments, with a higher yield using
both inoculants.
There was an addition of phosphorus fertilizer at one of the
sites. At Beausejour-H, 30 poundsactual P was added with the
soybeans at planting.

Ltd.November 2013 11
Combine Losses:
Table 4 shows header types used and soybean losses after
combining. Combine losses wereminimal to high and ranged from 0.4
to 2.3 bus/acre. Combine losses are considered minimal ifless than
2% of yield (Generally, less than 1 bus/acre). All combines had
flexheads except forTeulon-W. Speeds ranged from 3-5 mph. Combines
equipped with air reels showed a 1 busheladvantage.
Comments on Individual trials:
Influences on yields between strips (See Appendices 2 and 3 to
look at individual trial results):
1. Compaction at seeding due to the ground being wet (varied
across all trials)1. Sprayer tracks in one strip but not in other
(varied across all trials)2. Excess moisture Beausejour-B3. Hail at
Beausejour-B4. Insects/disease – low levels5. Light frost at

MPGA Soybean Inoculation Trials Prepared by Tone Ag Consulting
Ltd.November 2013 12
4 Recommendations
1. Need two more years of On-Farm inoculation trials to obtain
more data to determine if usinggranular inoculant on soybeans
provides an economic return.
5 Conclusions
1. This study showed there was only a 0.5 bus/acre yield
advantage of using both granular andliquid inoculants vs. only
liquid inoculant.
2. There is an economic return of using granular inoculant 3 out
of 10 times (30%).3. Nodulation between the two treatments was the
same at 8 out of 10 trial locations.4. The top 4 out of 5 yields
came from fields seeded soybeans on soybeans and had high
nodulation in both treatments.5. There appeared to be no
difference in yield in the different row spacing of 7.5 inch to 20
inch.6. Soybean yields appear to have a relationship with high
plant ground cover.
