[Dr. John Rupe, Professor Plant Pathology, University of Arkansas System Division of Agriculture.] Today we’re going to talk about seed vigor and how it affects stand establishment. This is something that’s important to think about now, as you plan for planting this coming season.

[Picture of soybean plants.] Seed vigor is the ability of a seed to produce a healthy seedling across the range of environments. [Dr. Rupe] In Arkansas, we plant soybeans beginning in April all the way through June, meaning that our seed is put into either cold soils all the way to very hot soils that can be very stressful. And so high vigor seed is important if we want to get a good stand.

So what are things that can affect seed vigor? Well, seed vigor begins with a production environment. Generally when seed are produced under cooler conditions, seed vigor is higher than when they are produced under hotter conditions.

[Picture of soybean seeds] The only information that is provided on the label is standard germination. [Dr. Rupe] So if you want to know what the vigor of your seed lot is, you should ask your seed dealer. They may have that information and be able to share that with you.

[Bar and scatter charts showing germination and vigor] In a survey funded by the Arkansas Soybean Promotion Board, we found that most seed sold in Arkansas has both high germination and high vigor. [Picture of soybean seeds.] However, a significant amount of seed lots had fairly low seed vigor, which could affect stand.

[Dr. Rupe] If you have a question about the seed that you’ve planted, take a sample at planting and send it to the Arkansas State Plant Board for germination and vigor testing. [Address of the Arkansas State Plant Board, 1 Natural Resource Drive, Little Rock, AR, 72205]
