A pot experiment was conducted to observe the growth pattern of phasey bean (Macroptilium lathyroides) in southwestern part of Japan and to investigate the effects of cutting frequency and cutting height on dry matter yield. Cutting treatments imposed were, 2, 3, 4 and 6 cutting times of frequency, and 5cm and 10cm of cutting height. Phasey bean, sown on June 10, flowered and seeded in August. From late August it assumed a twining habit and grew well till the first frost. It produced higher dry matter under infrequent cuttings, however it did not persist under 6 times cutting. The effect of cutting height on dry matter yield was not significant.
