Corn Silage

DuPont Pioneer has the right corn silage products to help you maximize milk per tonne as well as yield per acre. What’s more, a lot of our plant breeding is done right here at home, at our corn research centres in Tavistock, Ontario and Coteau-du-Lac, Quebec.

IMPORTANT

Trait rating scores provide key information useful in selection and management of Pioneer® brand hybrids in your area. Information and ratings are based on comparisons with other Pioneer brand hybrids, not competitive hybrids. Information and scores are assigned by Pioneer Research Managers. Scores are based on period-of-years testing through 2014 harvest and were the latest available at time of printing. Some scores may change after 2015 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 or contact a Pioneer sales professional for the latest and most complete listing of traits and scores for each Pioneer brand product.

RATINGS

9 = Outstanding; 1 = Poor; Blank = Insufficient Data.

TECHNOLOGY SEGMENT:

AM — Optimum® AcreMax® Insect Protection system with YGCB, HX1, LL, RR2. Contains a single-bag integrated refuge solution for above-ground insects.

AMXT (Optimum® AcreMax® XTreme) — Contains a single-bag integrated refuge solution for above- and below-ground insects. The major component contains the Agrisure® RW trait, the YieldGard® Corn Borer gene, and the Herculex® XTRA genes.

AMX (Optimum® AcreMax® Xtra) — Contains a single-bag integrated refuge solution for above- and below-ground insects. The major component contains the YieldGard® Corn Borer gene and the Herculex® XTRA genes for resistance to corn borer and corn rootworm.

HX1 — The Herculex® I insect protection trait offers a high level of resistance to European corn borer; very good resistance to black cutworm and western bean cutworm; and moderate resistance to corn earworm.

HXX — Herculex® XTRA contains the Herculex I and Herculex RW genes for resistance to the same pests as Herculex I as well as protection against larvae of western corn rootworm and northern corn rootworm.

LL — Contains the LibertyLink® gene for resistance to Liberty® herbicide.

RR2 — Contains the Roundup Ready® Corn 2 trait that provides crop safety for over-the-top applications of labelled glyphosate herbicides when applied according to label directions.

YGCB — The YieldGard® Corn Borer gene offers a high level of resistance to European corn borer; and moderate resistance to corn earworm.

SILAGE CRM (Silage Comparative Relative Maturity)

With no industry standard for silage maturity, comparing maturity and harvest moisture among corn-for-silage hybrids is difficult. Pioneer silage CRM ratings provide a relative comparison among Pioneer hybrids of rates at which hybrids reach harvestable whole-plant moistures. It is on the same scale as the CRM rating provided for grain-corn hybrids and does not represent actual days from planting or emergence to harvest moisture or half milkline.

SILAGE YIELD

Based on whole-plant yield per acre (adjusted to 30% dry matter) from multi-year comparison of hybrids within a maturity range not exceeding 5 silage CRM units.

STARCH

Based on a relative comparison of the whole-plant concentration of starch among individual hybrids.

FIBRE DIGESTIBILITY

Based on 24-hour enzymatic estimate of percent degradable neutral detergent fibre (NDF) as a percent of total NDF in whole-plant sample, predicted by NIRS.

WHOLE-PLANT DIGESTIBILITY

Based on estimated 24-hour in vitro whole-plant digestibility percentage (dry matter basis), as predicted by Near Infrared Reflectance Spectroscopy (NIRS).

SILAGE CRUDE PROTEIN

Based on the amount of crude protein in the whole plant, predicted by NIRS.

MILK PER ACRE

9 = Outstanding; 1 = Poor, based on University of Wisconsin MILK2006 utilizing silage yield, nutrient content and digestibility.

MILK PER TON

9 = Outstanding; 1 = Poor, based on University of Wisconsin MILK2006 utilizing silage nutrient content and digestibility.

STRESS EMERGENCE

All hybrids are expected to establish normal stands under average soil conditions. Stress emergence is a measure of the genetic ability or potential to emerge in the stressful environmental conditions of cold, wet soils or short periods of severe low temperatures, relative to other Pioneer hybrids. Ratings of 7-9 indicate very good potential to establish normal stands under such conditions; a rating of 5-6 indicates average potential to establish normal stands under moderate stress conditions; and ratings of 1-4 indicate the hybrid has below average potential to establish normal stands under stress and should not be used if severe cold conditions are expected immediately after planting. Stress emergence is not a rating for seedling disease susceptibility, early growth or speed of emergence.

DROUGHT TOLERANCE

Drought tolerance is a complex trait, determined by a platform's ability to maintain yield in limited moisture environments. A higher score indicates the potential for higher yields vs. other platforms of similar maturity in limited-moisture environments.

PLANT HEIGHT

9 = Very Tall; 1 = Short.

GIBBERELLA EAR ROT CAUTION:

Ratings based upon visual symptoms at harvest. If Gibberella ear rot has caused significant damage in the past, growers should consider planting only hybrids with at least moderate Gibberella ear rot ratings of 5 or higher.
