“…The rationale for this lack of adoption is not clear but is possibly due to the cost of rising plate meters (US$400–600), the precision of the measurement when studying grasses low in height (Sharrow, 1984), or limited commercial availability in the United States, as rising plate meters are commonly used in the United Kingdom and New Zealand. Most commonly, a ruler, a prism affixed to a ruler, or clippings harvested with a mower are used to assess growth or verdure height in turf research (Law, Bigelow, & Patton, 2016; Li, Henderson, Vanini, & Rogers, 2013; Skogley & Sawyer, 1992). A review of modern turfgrass science experiments in Crop Science and the International Turfgrass Research Society Journal from 2000 to 2019 found that 81 of the 1,316 published experiments measured turf height or collected grass clippings to quantify growth and/or yield in the field.…”

Growth or yield is an important characteristic to measure in crop science experiments. Turf researchers often use rulers or harvest grass clippings to measure growth and yield, respectively. Rising plate meters or floating disk meters are used for nondestructive measurements of forage canopy height to estimate herbage biomass, but this technique is not commonly used by turf scientists. Using the rising plate concept and integrating new technology, our objective was to develop an easy‐to‐construct, low‐cost device that could rapidly and accurately measure canopy height, growth, and estimate yield in turf research. A device called the “Turf Height Tester” with a floating platform and a laser distance measurement tool was constructed within a US$167 budget. The tester was able to precisely measure recently mown turf canopy height at the tested bench heights of 4.9–10.2 cm. The Turf Height Tester was advantageous for comparing the growth of turfgrasses with contrasting growth rates, and turf response from N fertilizer applications in a nondestructive manner. The tester, which outputs data via Bluetooth to the nearest 0.1 mm, correlated well with other turf canopy height measuring tools but had a lower CV. Collecting ∼18 measurements per minute, the tester allows for data collection from 1.8 plots per minute (includes 5 pre‐ and 5 post‐mowing measurements) compared with the more labor‐intensive practice of harvesting and weighing grass clippings from a rotary mower with a bagging attachment at 0.2 plots per minute. Further, there was a strong relationship across experiments (R2 = .62–.94) between growth measurements using the tester and dry matter clipping yield.

The golf industry has a $170 billion economic impact in the United States, and a vital aspect of the sport is golf course putting green performance. The goal of putting green management is to provide a surface on which a golf ball is rolled uniformly while maintaining acceptable yearlong turfgrass quality. Several devices have been developed to quantify golf ball roll dynamics on putting greens; however, there are limited methods to measure putting green ball roll uniformity. The objective of this research was to assess putting green ball roll uniformity by measuring the dispersion of golf balls released from a modified Perfect Putter device. The Perfect Putter is a lightweight and portable ramped device that was modified to include a fixed hinge to minimize human error associated with golf ball release and a wider base for increased stability. Our method for quantifying ball roll uniformity was as follows: 20 golf balls were released from the device and marked individually. Dispersion length was quantified by measuring the maximum linear distance between two marks parallel to the roll line, whereas dispersion width was quantified by measuring the maximum linear distance between two marks perpendicular to the roll line. These two values were multiplied together to calculate the area of golf ball dispersion. This method measured a range of dispersion areas among geographic locations, turfgrass cultivars, and turfgrass canopy heights. This rapid test of putting surface ball roll uniformity has potential to aid bermudagrass turfgrass managers in maximizing putting green playability.
