Interpretive Summaries:
1998 - Phosphorus and Potassium Requirements of Seashore Paspalum for Establishment and Grow-in, Over-Wintering and Overseeding Cool Season Species
1997 - P and K requirements of Seashore paspalum for establishment and grow-in, over-wintering and overseeding cool season species
Phosphorus and Potassium Requirements of Seashore Paspalum for Establishment and Grow-in, Over-Wintering and Overseeding Cool Season Species, 1998
Seashore paspalum was established by sprigging due to limited availability of planting material for this ecotype. Sufficient coverage was attained by June of 1997, and then P and K treatments were initiated. Treatment measurements and evaluations were initiated in late 1997. The studies will be continued through 1999 to allow at least two years of in-field evaluation and extensive data analysis, multiple regression analysis, and write-up of results.
Seashore paspalum is well suited to a wide range of soil pH levels and tolerates both low and high temperature extremes and short mowing heights. During 1998, N was applied at 4 and 8 lb/1,000 sq. ft. and K at rates of 2 and 8 lb K2O/1,000 sq. ft. Preliminary results indicate that higher rates of N reduced wear injury, improved plant recovery by increased shoot growth. Response to K appeared to be more subtle. GA-17F
