Dry Matter and Protein Yields and Nitrate Content of Piper Sudangrass (Sorghum sudanense (Piper) Stapf.) in Response to Nitrogen Fertilization1

  1. D. C. Summer,

  3. H. S. Etchegaray2



The experiments conducted suggest that 200 pounds of nitrogen is about the optimum as a split application when pasturing or greenchopping irrigated Piper sudangrass. Greater amounts do not appreciably increase yields but do account for relatively high rates of accumulated nitrate (NO3-), in the harvested forage.
