Composition and Seed Quality of Kentucky 31

Kentucky 31 grass seed is composed almost entirely of tall fescue (Festuca arundinacea) seeds, specifically bred for durability and adaptability. The seed quality is crucial for successful establishment and long-term performance.

Typical components of Kentucky 31 seed include:

  • Pure live seed (PLS): Percentage of viable seeds capable of germination.
  • Inert matter: Non-seed material such as chaff and dust.
  • Other crop seeds: Seeds of other grass species that may be mixed inadvertently.
  • Weed seeds: Seeds of undesirable plants that can affect turf quality.

The following table outlines a typical seed analysis for Kentucky 31 grass seed:

Component Typical Percentage Significance
Pure Live Seed (PLS) 85-95% Indicates seed viability and quality
Inert Matter 3-10% Non-germinating material; affects seeding rates
Other Crop Seeds <1% Unwanted but usually harmless seeds
Weed Seeds <0.5% Can introduce unwanted species into the turf

Seed quality can vary depending on the supplier and seed lot. Selecting high-quality Kentucky 31 seed with a high PLS percentage ensures better germination rates and a healthier, denser turf stand.

Uses and Applications of Kentucky 31 Grass Seed
