Abstract

Mexican lawn grass (Zoysia matrella) is a perennial mat-forming species suited for the landscaping industry due to its versatile adaptability. The pleasing appearance of the lawn grasses can be achieved through mowing at regular intervals to avoid a shabby appearance, which requires skilled persons and ends up with expensive operation. Under these circumstances, the experiment was intended with the commonly available growth regulators for their efficiency in the reduction of the mowing cycle without losing or hampering their visual quality attributes. The application of 1.0% chlormequat chloride (T4) produced a mean grass leaf length of 2.00 cm, which was remarkably lower than that of control (T9), i.e., 4.87 cm. The same pattern of growth was exhibited during the 45th and 90th days after spraying. The mean turf shoot length (7.80 cm) and root length (13.40 cm) were observed in the control plots, while the application of 1.0% chlormequat chloride (T4) produced 3.83 cm and 7.94 cm, respectively, determining its ability to hamper the growth of turf grass. The Z. matrella grass failed to produce flower heads by the application of 1.0% mepiquat chloride (T2), 0.5% chlormequat chloride (T3), 1.0% chlormequat chloride (T4), 0.5% maleic hydrazide (T7) and 1.0% maleic hydrazide (T8). The control plots devoid of growth regulators initiate flower heads after 70 days. From the study, the application of 0.5% chlormequat chloride (T3) and 1.0% chlormequat chloride (T4) exerted a low level of thatch accumulation and no flower head formation was observed with maximal visual scoring, leading to the commercial expeditions for the turf industry.
