September 2018 21 Mowing Factors General factors to consider when describing the effects of mowing include growth habit (how a turfgrass spreads), turf - grass use, and leaf growth rate influenced by climatic and cul- tural influences. Many cool-season turfgrasses, such as tall fes- cue and perennial ryegrass, possess a bunch-type growth habit, basically spread by tillers, and require a relatively higher height of cut (HOC). Many warm-season turfgasses, such as bermudagrass and zoysiagrass, possess a creeping growth habit, spread by stolons and/or rhizomes, and require a lower HOC. In terms of turf - grass use, the mowing requirements (HOC and mowing fre- quency) are different for a turfgrass used in a park compared to a turfgrass used in a sports field. In terms of leaf growth rate, the mowing requirements of cool-season turfgrasses are differ - ent during spring and fall compared to during summer and win- ter, while the mowing requirements of warm-season turfgrasses are different during the summer compared to during the spring, fall, and winter. Mowing Effects Specific effects of mowing include its impact on aboveground and belowground plant growth. Mowing at a lower HOC (with - in the mowing tolerance range for a particular turfgrass species) generally results in a higher quality: more shoots and leaves Above This table measured the effect of mowing height on Tifway Bermuda grass during the study.
