Tables


Table 7. Seeding rates based on pure live seeds (PLS) and bulk pounds per acre for tall, warm-season native grasses in areas of adaptation.

Seed quality**
Species Optimum lb/acre PLS* Percent of full seeding Amount of PLS (lb/acre) Purity Germination Factors*** Bulk seed (lb/acre)
Big bluestem 10.6 0.50 5.3**** 70 60 2.4 12.7
Indiangrass 10.0 0.30 3.0 75 60 2.2 6.6
Switchgrass 4.5 0.20 0.9 95 80 1.3 1.2
Totals 9.2 20.5


* Based on recommended full seeding rate of 40 PLS per aquare foot.

** Percent purity and germination are shown as minimum standards for good
quality seed. Use actual purity and germination of seed lot to calculate
bulk pounds.

*** Conversion factor from Table 3 (Conversion factors to determine pounds
of bulk seed needed for 1 pound of pure live seed).

**** Optimum lb/acre PLS x Percent of full seeding = Amount of PLS.
