## Abstract
Abstract This study aims to select maize hybrids that can tolerate acidic soil stress using several tolerance indexes. The research took place at two sites. Muneng Experimental Farm has average soil (pH=6.8), and Moncongloe Experimental Farm has acid soil (pH=5.8) from January to April 2023. A Randomized Complete Block Design (RCBD) was employed to organize ten maize hybrids, namely TH 1, TH 2, TH 3, TH 4, TH 5, TH 6, TH 7, TH 8, NK 6172, and P 32, each replicated three times. The variable observation was yield, standardized to 15% moisture content. To determine the tolerance of maize, six tolerance indexes were applied: The Stress Tolerant Index (STI), the Stress Susceptibility Index, the Mean Productivity (MP), the Harmonic Mean, the Stress Relative index (SI), and the Stress Susceptibility Percentage Index (SSPI). The result showed that hybrids that tolerate acidic soil are TH 1 and TH 2, as indicated by their average rating and standard deviation. In contrast, TH 5 and TH 7 hybrids are sensitive to acidic soil conditions. The STI and MP are suitable tolerant indexes that can select acid-tolerant hybrids with high yields under optimum and acidic conditions.
