The Lee-Kramer shear press has been found to afford a rapid means of measuring the maturity of pigeonpeas. The high correlation coefficients between shear-press readings and starch, alcohol-insoluble solids, and total-solids content, and with the percentage of yellow pigeonpeas, indicate that the shear press can be used with accuracy to measure the maturity of pigeonpeas. Regression equations can be used to calculate the values for the objective indices from the corresponding shear-press readings.
