Southern pea seeds were grown 2 yrs with treatments of ammonium nitrate fertilizer 0, 30, and 60 kg/ha and simazine 0, 2,000, and 4,000 ppm applied as a foliar spray. Yield, proximate analysis, amino acid content, and protein quality were determined. No differences were found in yield, crude fat, and crude fiber. Ash, protein, and several of the amino acids increased with the 30 and 60 kg/ha nitrogen fertilizer treatments. Treatments with simazine had no effect on the essential amino acid content. In the Southern pea seeds, protein quality was decreased by the treatments with nitrogen fertilizer, simazine, and combinations of these treatments.
