    Study Notes

    Webinar on Seed Quality and Seed Labels

    • The webinar will discuss seed quality, measurement, importance, and seed labels, and lab reports.

    • The presentation will run for 45-50 minutes with a 10-minute Q&A session.

    • The series of webinars provide practical advice and highlight problem areas in the seeding process.

    • Seed quality varies by species, lot, and year, with some species having low germination rates or requiring intense processing.

    • High-quality seed is true to type, has high purity, high germination, low dormancy, and is certified.

    • Seed labels and lab reports are crucial for evaluating seed quality before purchase.

    • Seed testing protocols are managed by the Association of Official Seed Analysts (AOSA), and each state has an official seed testing lab.

    • The Federal Seed Act regulates seed sold and shipped across states, while state seed laws regulate seeds sold within a state.

    • Seed quality is determined by purity and viability, with purity representing the amount of pure seed and viability indicating live seeds.

    • Seed dormancy, defined as viable seed that fails to germinate under normal conditions, can be overcome by various treatments.

    • Pure Live Seed (PLS) is calculated by multiplying percent purity by percent germination or viability, divided by 100, and is crucial for achieving the target stand in plantings.

    • The PLS rate determines the amount of viable seed needed for planting, and differences in PLS between seed lots require adjustments in seeding rates.Calculating Bulk Seeding Rate for Planting

    • The purity of the seed affects the amount of seed needed for planting.

    • The bulk seeding rate is always slightly higher than the pure live seed (PLS) rate.

    • The recommended PLS seeding rate per acre is divided by the percent PLS of the seed to determine the bulk seeding rate.

    • An example is given for planting goldar blue bunch wheatgrass at eight pounds PLS per acre with a PLS of 89.

    • The seed tag should indicate the purity of the seed.

    • To calculate the bulk seeding rate, divide the recommended PLS seeding rate per acre by the percent PLS of the seed.

    • In this case, the bulk seeding rate for goldar blue bunch wheatgrass at eight pounds PLS per acre with a PLS of 89 would be calculated.

    • Pure live seed refers to the viable seed in a lot, excluding inert matter and other seeds.

    • The bulk seeding rate accounts for the purity of the seed and ensures the correct amount is planted.

    • It's important to use the correct bulk seeding rate to achieve the desired PLS rate for planting.

    • Proper calculation of the bulk seeding rate is crucial for efficient and effective planting.

    • Understanding the relationship between PLS, purity, and bulk seeding rate is essential for successful planting.
