Mowing height and irrigation effects on above ground biomass production of <i>Schedonorus arundinaceus</i>

Abstract The utilization of biomass from golf course and home lawn landscapes greatly impacts soil conditions, plant health, and municipal waste disposal. In 2020 and 2021, research was conducted to evaluate aboveground biomass production of tall fescue ( Schedonorus arundinaceus Schreb.) in relation to mowing height. Irrigated and non‐irrigated plots of tall fescue were mown to 5.08, 6.35, and 7.62 cm. Biomass yields were determined by dried clipping weight. In general, 5.08 and 7.62 cm mowing height treatments consistently produced the greatest and lowest biomass yields, respectively. With few exceptions, results were consistent between irrigated and non‐irrigated trials. For tall fescue, findings suggest an inverse relationship between height of cut (HOC) and aboveground biomass production. Regardless of irrigation , tall fescue clipping yields declined when mown at a greater HOC.
