Physiological traits play an important role in crop growth and development. Comparative investigation on small millets, with respect different physiological traits such as leaf area index, leaf area duration, specific leaf weight, chlorophyll content, gas exchange parameters etc. and their relationship with grain yields were meager, and will be useful in small millets improvement. Therefore, this study aims to investigate the physiological traits and their relationship with grain yields five small millets (foxtail millet, proso millet, kodo millet, little millet and barnyard millet). Physiological traits such as leaf number, leaf area, specific leaf weight, chlorophylls a, b, and total chlorophyll, SPAD reading, photosynthetic rate and transpiration rate have reached their maximum value at grain development stage in all the crops, while leaf area index was the maximum at grain development stage, highest root length was achieved at maturity stage, and highest stomatal conductance was at flowering stage. Among different cultivars within the each crop, a cultivar having high leaf number, leaf area, leaf area index, leaf area duration, specific leaf weight, chlorophyll a, b, and total chlorophyll, chlorophyll fluorescence ratio, SPAD reading, photosynthetic rate, transpiration rate, stomatal conductance and root length, had produced higher grain yield. This shows importance of these traits in for enhanced yields in small millets.
