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.
