0, 3, 6 or 9 kg N/ha was applied as urea to the foliage of groundnut cv. Early Bunch, NC-Fla 14 and Florunner or to the soil at 85 or 118 days after sowing. Yields of NC-Fla 14 and Florunner increased with increasing foliar urea rates. The yield of Florunner and seed oil contents of all 3 cv. generally decreased with soil-applied urea. N increased seed total protein and soluble carbohydrate contents and the methionine content of Early Bunch and NC-Fla 14 seeds. Free amino-acid contents increased with increasing urea rates.
