1. Sport Field Grasses

2. Cool Season Grasses  C3 Plants  Optimum temp: 60 -75  Most came from Europe – Forest Fringe grasses  Good low temp hardiness  Established by seed and sod  In south US: grows fall, winter, spring – dead or dormant in summer  In north: grows spring, summer, fall – dormant in winter

5. Kentucky Bluegrass Poa pratensis  Blue color  Medium leaf texture  Medium leaf density and color  Forms rhizomes – good sod  Good recuperative potential  Long –lived perennial  Good low temp hardiness  Lacks shade adaptation – full sun

6. Kentucky Blue grass

7. Kentucky Bluegrass Cont.  Good wear tolerance  Likes fertile, moist well-drained soil – pH 6-7.0  Not drought tolerant  Tendency to produce thatch  Several varieties  Fert:.4-1 lb N/1000 sq ft/ growing month  Med – med. high intensity of culture  Mow 1-2” but 1.5-2” optimal  Used for fairways, sports fields, lawns

8. Creeping Bentgrass Agrostis palustris  Pale green  Medium to fine texture  High density  Established by seed or vegetatively  Slow establishment  Long-lived perennial  Excellent low temp hardiness  Tolerant to shade  Fine textured, fertile, moist soil  pH 5.5 -6.5

9. Creeping Bentgrass

10. Creeping Bentgrass Cont.  tolerant to salinity and flooding  used on greens (south), tees and fairways (north)  high culture intensity  mow.2 -.7”  fert.5 – 1.4 lbs N/1000 sq ft/ growing months  prone to thatch  susceptible to disease

11. Tall Fescue Festuca arundinaceae  very coarse texture  low density  medium green color  established by seed – good rate  bunch type  short – lived perennial  seed every fall  poor low temp hardiness  good heat, drought, wear tolerance

12. Tall fescue

13. Tall Fescue cont.  higher compensation point  medium shade adaptation  fine texture, moist, fertile soil  pH 5.5 – 6.5  salt, flooding tolerant  extensive root system  fert 2-4 lb N/1000 sq ft/per year  minimal thatch

14. Tall Fescue cont.  good heat, drought, wear tolerance  med – low intensity of culture  used for lawns, sports fields, roadsides, utility areas  mow: turf –above 1.5 inches

15. Perennial Ryegrass Lolium perenne  short-lived perennial  bunch type  medium texture  glossy yellow to dark green  tough fibrous vascular bundles  good wear resistance  establishes quickly from seed  low recuperative potential  poor tolerance to heat, drought stress

16. Perennial Ryegrass

17. Perennial Ryegrass cont.  fertile, moist soil  pH 6.5 -7  good salt tolerance  lawns, sports fields, roadsides  winter over seeding  mow 1.5 – 2”  fert.4 -1 lbs N/1000 sq ft/ growing month  endophyte enhanced

18. WARM SEASON GRASSES  C4 plants  Optimum temp 85-95  West Indies  Africa  North America  Mowed closer  Deeper rooted  More heat, drought, wear tolerance  Less low temp hardiness  Sod, sprigs, plugs

21. Common Bermuda Cynodon dactylon  Africa  Med texture  High density  Dull green  Rhizomes, stolons  Fibrous root system  Extensive and deep roots  Established by seed  Very quickly established  Long – lived perennial

22. Common Bermuda Grass

23. Common Bermuda cont.  Good heat, drought, wear tolerance  Poor shade, low temp tolerance  Well drained, fine, fertile soil  pH 5.5 -7.5  good salt, flooding tolerance  lawns sports fields, tees, fairways, greens  med to high culture  mow.25 – 1”  fert.8 -1.8 lbs N/1000sq ft/growing months

24. Hybrid Bermuda Cynodon transusulensis  Same as common Bermuda except:  fine texture  established vegetatively
