| Abstract/Contents: | "Recent field studies have shown the N form has an effect on the severity [of] summer patch disease, caused by Magnapothe poae, in fine fescue (Festuca spp.) turf. However, our understanding of the growth responses of fine fescue to N form is limited. A greenhouse study was conducted to determine if N form influenced growth, water use, and N accumulation in 'Reliant' hard fescue (Festuca ovina ssp. duriuscula (L.) Koch.). Grasses were established for 5 weeks with 1/4 strength Hoagland's solution (50 mg N per L). After establishment, plants were grown for 15-d in a hydroponics system containing 50 ppm of N as either NH₄, NO₃, or a 1:1 mixture of NH₄ and NO₃. Nutrient soltuions were continuously aerated throughout the study and pH was monitored daily and adjusted to 6.1 with either H₂SO₄ or Ca(OH)₂. Nutrient solutions were changed every 2 to 3 days and a 10-ml sample of the solution was collected from each tub for N uptake analysis. Total amount of water used from each tub was determined by weighing the tub and solution without the plants before the nutrient solutions were changed. Plants grown with NO₃-N had dry shoot, root, and total biomass of 18.5, 32.4, and 20.3% greater than plants grown with NH₄-N. As expected, the highest NH₄-N and NO₃-N tissue concentration were observed in plants grown in NH₄ and NO₃, respectively. Total tissue N was higher in grasses grown with NH₄-N compared to NO₃-N, but no differences in total N uptake from solution or cumulative water use were observed. The results indicate that vigor of hard fescue fertilized with NO₃-N may be increased." |
