● Product Profile

PGI 437 Alfalfa Proven Genetic Innovation

Management Profile

• The variety to plant if one or more cuts during the growing season may be in the field to late flower due to weather or grower choice. Improved Standability helps reduce field and harvest loss and protects yield and forage quality better than varieties that lodge when harvest is delayed.
• Adapts to relaxed 3-cut, Traditional 3-4 cut or aggressive 4-5 cut, management systems.
• Maintains forage quality when harvest is delayed by management choice or weather.
• Fits production zones where fall dormancy 3, 4 or 5 alfalfas are recommended
• Four and five cut harvest systems maximize yield and animal performance
• Medium-early maturity to late bud/early flower growth stage

Field Appearance at Harvest Maturity

• Tall, showy plants that are very upright and eye-catching
• Medium green plant color with high multifoliolate leaf expression

Key Agronomic Characteristics

Fall Dormancy 4 Winter Hardiness Rating 2 Multifoliate Leaf Expression 99% Standability Rating 8 Wisconsin Disease Rating Index 28 of 30

PGI 437 Alfalfa was developed from crossing unique, tall, fastgrowing European germplasm, screened for U.S. adaptability, onto elite U.S. fall dormancy 4 plants selected for superior yield, forage quality and persistence. The resulting alfalfas express either faster growth and/or improved standability traits and are designated as StandFast Alfalfas.

Standability extended to late flower versus the bud stage for non-StandFast varieties. Reduced field and harvest losses, as well as improved harvest ease.

Standability protects forage quality if harvest is delayed, CP, NDFD, ADF and RFQ are equal to the best competitive alfalfas. StandFast alfalfa is a non-GMO technology with patent pending and a registered trademark.

PGI 437 Alfalfa

Ratings are based on average performance of the variety over a wide range of climate and soil types. Actual performance may be adversely affected by extreme conditions. Unless stated, ratings are based on standardized testing procedures endorsed by the North American Alfalfa Improvement Conference.

Standability Rating: 1 = Lodged, 9 = Erect. Ratings are in relationship to check varieties at mid-flower maturity

StandFast Standability Advantage

• Non-StandFast alfalfas usually begin to lodge during the bud stage when subjected to inclement weather.
• Reduce field and harvest loss.
• Protect yield and forage quality to the late flower stage of maturity.
• Adapts to harvest systems where one or more crops may be in the field to late flower.
• Improves standability when harvest is delayed by weather or the manager’s choice.

©2009 Producer's Choice Seed Lodged and downed crop means lost yield and reduced quality. PGI 437 alfalfa gives growers the potential for more harvestable yield when harvest is delayed.
