Abstract

Abstract

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.
