Two trials were conducted to determine the effect of varying cutting height and interval on growth and forage quality of Ubon paspalum (Paspalum atratum) pastures grown in Thailand on low fertility soils. In Trial 1, an increase in cutting height (from 0 to 20 cm above ground level) increased total DM yield at 20-d cutting intervals, had no effect at 30 days and decreased yields at 60-d cutting intervals. Cutting interval significantly increased DM yields in Trial 1 with the major response between 30- and 60-d intervals. Increasing the interval between harvests reduced concentrations of CP, K and P but increased the concentrations of NDF and ADF. In Trial 1, increases in cutting interval and cutting height increased stubble and root DM per plant.
