Selected organic and mineral analyses of common beans, peanut kernels, and cowpeas were determined. Simple correlations were computed between organic and mineral components to investigate possible linear relationships that might be useful. Most correlations between mineral and organic components were negative, and relatively low coefficients of determination (r2) indicated little merit in attempting to predict organic components from inorganic compositions and sample linear models. A positive correlation between stachyose and the N content of common beans was observed.
