• Enable growers to position products at the highest

yielding planting rates for their fields based on multi-

location data.

• Increase grower success and understanding of product

placement based on individual field attributes such as

tillage system, irrigation, and planting date.

• 202 corn silage trials in WI, MN, IA and SD, including 34 PKF trials in 20141.

• Focused on the newest Pioneer® brand BMR and non-

Trial

PKF Trial Configuration

• Local participation, local results - Trials are planted,

managed and harvested by forage growers in your area

• Large enough to matter - 10-20 acres per trial

• On-farm weighs - Harvested trial strips are weighed on

driver-over scales on the farm

• Forage Quality - samples were collected from each strip

at harvest and sent to Pioneer Forage Labs for forage

quality analysis

Maximizing

Performance

• Silage Yield and Milk per

Acre were maximized

when planted at 36,000

seeds per acre.

• Increasing plant

population resulted in a

higher proportion of

tonnage coming from the

green portion (NDF) of

the plant.

• By increasing the green

portion of the plant, the

grain to stover ratio was

reduced, lowering overall

starch content at higher

seeding rates.

• Fiber digestibility of the

plant was similar across

all seeding rates.

Corn Silage Management Considerations

Management Implications

• Normal planting dates (before May 20)

resulted in higher silage yields, milk per acre,

and starch content in 2014 trials.

• Silage yield for late planted corn trials was

less responsive to seeding rate changes than

for early planted trials.

• Silage yield and milk per acre were

maximized at seeding rates of 36-42,000 for

early planted corn silage hybrids.

Planting Date Differences for Corn Silage in 2014 PKF Trials

2014





• At irrigated locations in 2014, silage yield and

milk per acre were maximized at the highest

seeding rates.

• Starch content and fiber digestibility declined

slightly with increasing seeding rate.

• Fiber content (NDF) was highest at the

highest seeding rates.

Irrigated Trial Response by Seeding Rate in 2014 PKF Trials

2014




• Tillage method had little influence on silage yield and milk per acre when corn was planted

before May 20th.

• Silage yield and milk per acre were maximized when conventional or conservation tillage

methods were used in late planting situations.

Notes

The foregoing is provided for informational purposes only. Please consult with Pioneer

sales professional for suggestions specific to your operation. Product performance is

variable and subject to a variety of environmental, disease, and pest pressures. Individual

results may vary.

Data is based on average of 2014 trials made in Wisconsin, South Dakota and northeast

Iowa and Minnesota through January 2, 2015. Product responses are variable and

subject to any number of environmental, disease and pest pressures. Individual results

may vary. Multi-year and multi-location data are a better predictor of future performance.

DO NOT USE THIS OR ANY OTHER DATA FROM A LIMITED NUMBER OF TRIALS

AS A SIGNIFICANT FACTOR IN PRODUCT SELECTION. Refer to

www.pioneer.com/products or contact a Pioneer sales representative or authorized dealer

for the latest and complete listing of traits and scores for each Pioneer® brand product.

1 Number based on trials entered in the system as of January 2, 2015. 2 All Pioneer products are hybrids unless designated with AM1, AM, AMRW, AMX and

AMXT, in which case they are brands.

IMPORTANT: Trait rating scores provide key information useful in selection and

management of Pioneer® brand products in your area. Information and ratings are based

on comparisons with other Pioneer brand products, not competitive products. Information

and scores are assigned by DuPont Pioneer Research Managers. Scores are based on

period-of-years testing through 2013 harvest and were the latest available at time of

printing. Some scores may change after 2014 harvest. Scores represent an average of

performance data across areas of adaptation, multiple growing conditions, and a wide

range of both climate and soil types, and may not predict future results. All products

within a hybrid family receive the same score unless observations indicate a significant

difference. Individual product responses are variable and subject to a variety of

environmental, disease and pest pressures. Please use this information as only one

component of your product positioning decision. Refer to www.pioneer.com/products or

contact a Pioneer sales professional for the latest and most complete listing of traits and

scores for each Pioneer brand product and for product placement and management

suggestions specific to your operation and local conditions.
