Choosing a Seed Variety

Many factors go into selecting the variety or varieties that you will plant on your farm.  It is not just yield potential, factors such as thresh-ability, plant height, resistance to lodging, test weight, straw management, winter hardiness, and other disease tolerances go into that equation.  Each grower may weigh those factors differently.  We suggest looking at variety trial results on several sites and over several years data, combined with talking with other growers in similar environments and farming practices.  Do not rely on someone who may cherry pick trial data.  Last year a seed dealer advertised one of their products topping the yield at an OSU site when only 15 miles away at another OSU site that variety was the bottom out of 40 varieties.  My point being, look at more than one trial over multiple years of data.  Several sites you can go to for variety testing information are: Cereal Central/OSU; Cereal Variety Testing, Washington, Oregon Elite Nursery Performance Data.

Technology Agreements

The varieties above that are noted with an * are Proprietary and require that a technology agreement be signed.  This is basically a “NO SAVE SEED AGREEMENT” that protects the parent companies property rights.  PGG cannot load seed until these agreements are in place.  If you have not been to the; web site and signed these agreements please do so before you get close to seeding.  We would suggest that you do agreements for OSU, WSU, UofI, Westbred, Limagrain, and Syngenta.  Also the Monsanto agreement if you ever plan to use any Roundup Ready Crops.  Scroll through the seed suppliers and click on PGG Inc.. When you get on the web site, click on the “grower” box and it will prompt you through the process.  There is a help line phone number if you need any assistance,  If you do not have internet, drop by and we will help you through it or have a PGG representative bring an Ipad out to get it done.  BASF is the only company we deal with that has not signed on to the AgCelerate program, they still require a paper agreement be signed annually for the “Clearfield Wheat” program.  If you plan to use Clearfield seed we will get one of these agreements to you.

Seed Certification

Certified seed must meet several standards such as genetic purity, inert purity, germination, and be free of all noxious weeds. The certified seed that is processed by PGG is held to a higher standard. When we review samples from the cleaner if the lot shows any unallowed weeds the entire lot is rejected.
The seed processed through the McKennon Seed Plant is certified with a few exceptions. Certified seeds are produced from registered or foundation seed lines. Using certified will help you maximized your yield potential.

By using certified seed you ensure that your seed meets the highest standards of quality and consistency. If you would like to review the certified seed lab lot analysis of the seed variety you plan to use please contact us.
