Abstract/Contents:A study in being done to determine the effect of nitrogen carriers on Cynodon dactylon x C. transvaalensis and Stenotaphrum secundatum. This report tells of the effects of oxamide and thermo-plastic coated nitrogen on the test plots. All were applied with an O.M. Scott drop spreader except for the sprayable oxamide powder. Rate of application was 2.0 lbs of N/1000 sq. ft. with irrigation following nitrogen application. Plots were maintained at a two inch height of cut with no pesticides being applied. Clippings were caught and weighed to determine the effect of nitrogen on the different plots. Results showed that the granular oxamide formulation produced a very high quality St. Augustinegrass. The sprayable type of oxamide produced an average turf quality but both forms did produce greater shoot length than previously seen. All the thermo-plastic coated nitrogen carriers tested produced quality turf. The 70 day release carrier produced much less shoot growth but good turf. The combination of 70 + 150 + 270 day release carriers produced similar effects to the 70 day but with more residual effects. The best was the 270 day release carrier; it produced a slower initial response but once it started working, it was superior to the other carriers. All thermo-plastic coated carriers produced less shoot growth on the St. Augustinegrass. Quick release fertilizers ammonium nitrate and ammonium sulfate produced low quality St. Augustinegrass with a low amount of shoot growth. Statistical chart on page 136.
