The seed/hull ratio maturity index (SHMI) methodology has been modified to better meet less than optimal growing conditins. The modifications include sampling methodology for minimizing variation in small plot samples, rapid drying of samples to minimize variation due to moisture content differences, and a preferred method for estimating SHMI. Data are also given on variations in the seed/hull ratio found in selected commercially grown cultivars of peanuts. The optimum seed/hull ratio values for ‘NC5’, ‘NC2’, and ‘Florigiant’ are between 2.9 and 3.1. Correlations between yield, dollar value, and the seed/hull ratio were found to be significant for NC5, NC2, and Florigiant.
