Seed density, specific gravity, nuclear magnetic resonance, Kjeldahl, and solvent extraction methods were evaluated for their effectiveness in estimating protein and oil content of soybean seed ( Glycine max (L.) Merrill). The Kjeldahl method was superior for direct measurement of protein. Nuclear magnetic resonance was superior to solvent extraction as a rapid, accurate method of oil analysis. Seed density and specific gravity were comparable for estimating protein and oil content under most conditions.
