Corn Stand Evaluation
• • •

•
When an injury event such as frost or hail occurs it is best to wait a few days to perform a stand assessment, as it will allow a better deter-mination of whether or not plants will recover.
Growth of green tissue near the growing point indicates that this plant would have recovered. Figure A.
Soft translucent tissue near the growing point indi-cates that this plant will not recover. Figure B
Stand counts should be taken randomly across the entire area of a field being considered for re-plant; this may include the entire field or a limited area where damage occurred.
Other factors to evaluate Stand uniformity • An uneven stand will yield less than a relatively even stand with the same number of plants.
Plant health • Plants that are severely injured or defoliated will have reduced photosynthetic capa-bility and a lower yield potential.
This plant was defoliated by hail. New green tissue indicates that it is recover-ing, but its yield potential has been reduced

• Variation in soil temperature caused by uneven crop residue distribution
• Soil crusting
• Insects of disease
Late emerging plants are at a competitive disadvantage with larger plants in the stand and will have reduced area, biomass and yield.
Corn yield is influenced by stand density as well as stand uni-formity:
• Variation in plant size can have a negative impact on yield
• Uneven emergence timing leads to uneven plant size
• Variation in soil moisture

Give Seedlings a Chance A few precautions can help growers avoid stressing emerging corn.
Choose hybrids with good stress emergence and high-residue suitability scores where needed.
Protect your stands with fungicide and insecticide seed treatments. Pioneer offers valuable additives through the Pioneer Premium
Seed Treatment program. Ask us for details or to learn more about corn and soybean seed treatments available go to our website, then
click on services, then choose seed treatment. There you can click on the LumiGEN seed treatment offerings to learn more.
Check weather before planting . If a cold front or winter storm is moving in, wait
If you can’t wait, at least shut it down a day or two before the storm hits. Pioneer research scientist in crop genetics report that fields
planted a few days ahead of a cold, wet event typically have better stands than ones planted just before the storm
Plant well-drained, low-residue fields first. Avoid working the soil when wet to minimize compaction and sidewall smearing.
Experience shows corn emerges best when planted at a uniform depth into well-drained soils with adequate moisture, good seed-to-soil
contact and a near-term warming trend.
2021 Pioneer Replant Policy If you find that you need to replant any field (for any reason) origi-nally planted with Pioneer brand corn, grain sorghum, forage sor-
ghum, sorghum sudangrass, sunflowers or soybean seed; Pioneer will furnish replant seed at 50% -100% off of the current variety price . The discount amount you qualify for will depend upon what level of Infinity Discount you are at.
Platinum customers qualify for 100% replant. Gold level qualify for 75% replant Silver level qualifies for 50% replant.
Replant seed will be authorized only for the same year that the product is invoiced. Replant seed will be of suitable maturity for the conditions. Pioneer is not obligated to furnish specific hybrids/varieties or kernel sizes for replanting.
Only the purchaser (person invoiced and paying for the order) is qualified for service under the replant policy. The replanting agreement is not transferable by the purchaser to any other seed used.
The sales representative is required to verify each field that is to be replanted. We will need the location of the field for replant to enter into the Pioneer system.
If you decide to not replant after the replant-ed stand is initially established then Pioneer
shall not be obligated to extend any replant offer should chemi-cals, weather, livestock, or other events cause damage to the growing crop.
Planting Outcome Effects On Corn Yield BY TOME DOERGE, MARK JESCHKE, & PAUL CARTER - FROM PIONEER CROP INSIGHTS
SUMMARY
• Uniformity of plant emergence, planting timing, plant population,
and evenness of plant spacing are four outcomes of planting that can
influence final corn yield.
• Research has shown that delayed emergence can reduce the yield of
individual plants in a stand; however, the notion that a plant emerging
more than 48 hours after its neighbors is a “weed” is clearly not sup-
ported.
• Corn yield potential declines as planting is delayed beyond the opti-
mum planting window for a given geography, and the yield penalty
tends to be greater in northern areas where the growing season is short-
er.
• Optimum plant population can be influenced by factors such as yield
level, hybrid, and weather conditions.
• The CoV and singulation readings on the planter monitor are valuable
real-time indicators of meter performance
but poor predictors of the agronomic conse-
quences of common, realistic non-ideal
planting outcomes.
• Within-row plant spacing uniformity does
impact grain yield; however, whole-field
impacts on grain yield are usually relatively
small, averaging about 1 - 2%.
• By far, a skip is the planting outcome that
contributes the most to yield loss, whereas
occasional doubles have no negative impact.
FOUR PLANTING OUTCOMES FOR SUCCESS
Planning and execution associated with corn planting are critical if
growers are to maximize the genetic potential of today’s elite corn hy-
brids. The simple secret for success is to “do everything right.” Many of
these key management decisions are made well before the planting
season, including choice of hybrid, crop rotation, tillage system, nutri-
ent placement, target planting rate, and row spacing.
These goals and their estimated typical impact on yield include:
1. Achieve uniform emergence (5-9%)
2. Plant within the optimum window (2-5%)
3. Achieve the correct population (1-2%)
4. Achieve uniform plant spacing (1-2%)
1. ACHIEVE UNIFORM PLANT EMERGENCE
A primary goal of corn growers is to achieve stands containing uni-
formly large-sized plants that consistently produce one full-sized ear
each. Small, delayed, or “runt” plants rarely, if ever, produce full-sized
ears. Traditionally, growers have assumed that the primary cause of
these smaller, undesirable plants was a delay in the time of emergence.
And often the cause for delayed emergence was assumed to be incon-
sistent seeding depth. Logically, late-emerging plants are less able to
compete for limited light, nutrient, and moisture resources with earlier-
emerging, larger neighbors.
2. PLANT WITHIN THE OPTIMUM WINDOW
Timely planting of full-season hybrids allows the corn crop to take full
advantage of the available growing season. Numerous studies have
shown that corn yield potential declines as planting is delayed beyond
the optimum planting window.
Yield reduction with delayed planting
Results from Pioneer planting date studies conducted over 18 growing
seasons show that yield was maximized when corn was planted within
the two-week period around the optimum planting date
3. ACHIEVE THE CORRECT POPULATION
Unlike planting timing, which is often heav-
ily influenced by weather conditions, plant
population is a yield determining factor
largely within the control of the grower.
However, determining and achieving the
ideal population to maximize yield is com-
plicated, as the optimum population in a
given situation can be influenced by a num-
ber of factors, such as yield level, hybrid,
and weather conditions
In general, optimum populations for corn
have steadily increased over time. Higher
populations accompanied by improved stress tolerance in hybrids have
contributed to incremental yield gains
4. ACHIEVE UNIFORM PLANT SPACING
Growers instinctively prefer corn stands with uniform plant-to-plant
spacing. A “picket-fence” stand is both aesthetically pleasing and pre-
sumably higher yielding.
Spacing metrics poorly correlated to yield
Agronomists have long known that the various planting outcomes that
result in increasing CoV and SD and declining singulation values can
have widely different impacts on resulting individual-plant grain yield
(Nafziger, 1996; Doerge et al., 2002; Nafziger, 2006). Thus, the use of
easy-to-measure plant spacing metrics that are poorly correlated with
individual plant yields has, unfortunately, created a tradeoff between
convenience and accuracy. This has no doubt contributed to incon-
sistent results in past research seeking to explain the impact of within-
row plant spacing on corn grain yield
Individual plant yield determinations provide new insights
Continued on page 4
A 2002 Pioneer study (Doerge et al.) uniquely allows for quantifying
the impacts of common and realistic non-ideal planting outcomes on
grain yield. This study was conducted in four different environments
(two in Iowa, one in Missouri, and one in Minnesota), across a wide
yield range of 109 to 206 bu/acre, and using hybrids with three very
different genetic pedigrees. In this study, within-row spacing measure-
ments and grain yields were determined on >6,000 individual plants.
MAJOR FINDINGS AND CONCLUSIONS
1) As expected, differences in grain yields resulting from common non-
ideal planting outcomes were indeed observed and are listed in Table 1
below.
Planting Outcome Effects on Corn Yield Continued
TABLE 1
2) These non-ideal planting outcomes typically, but not always, result-
ed in lower grain yield.
3) In general, yield loss due to misplaced plants is negligible if plants
are displaced from their preferred location
4) The planting outcome caucusing the greatest yield loss is percent-
age of skips
5) Not all skips are caused by the planter some are from unsuccessful
germination or emergence issues.
6) Occasional doubles do not negatively impact yield

seen @ Pioneer Seeds.
Several of you do plots and side by side comparisons each year. If you have not done this in the past and would like to try some products for potential future use, please let us know. We are happy to help you and provide the seed for trying new varieties.
Pioneer has always encouraged farmers to test new hybrids and varieties. It has been our
policy to provide seed for these trials. Our only request is that we be allowed to harvest and weigh the hybrids being tested. Bushel weight and moisture can have a large effect on final yield.
Accurate measurements with a weigh wagon moisture testing equipment will provide reliable yield results. If you would like to test a particular hybrid or hybrids please let us know and we will be happy to provide the seed.
