Performance Of Kansas State University’S Cold And Large Patch-Tolerant Zoysiagrasses In The National Turfgrass Evaluation Program Test, Jack Fry, Manoj Chhetri
Performance Of Kansas State University’S Cold And Large Patch-Tolerant Zoysiagrasses In The National Turfgrass Evaluation Program Test, Jack Fry, Manoj Chhetri
Kansas Agricultural Experiment Station Research Reports
The National Turfgrass Evaluation Program (NTEP) Zoysia Test was planted in 2019 at the Kansas State University Olathe Horticulture Center, Olathe, KS. Since planting, three experimental genotypes developed at K-State (with cooperators noted below) have outperformed ‘Meyer’ in establishment rate, turf quality, drought tolerance, and fall color. Earlier research has demonstrated large patch tolerance in all three experimental genotypes.

Using Ethephon For Seedhead Suppression Of ‘Innovation’ Zoysiagrass, Manoj Chhetri, Jack Fry, Megan Kennelly
Kansas Agricultural Experiment Station Research Reports
The performance of ethephon (Proxy) on seedhead suppression of ‘Innovation’ zoysiagrass was evaluated during the 2019–2020 growing season in Manhattan, KS. Treatments evaluated Proxy applied in a single autumn application at 5 fl. oz./1,000 ft2on multiple dates between August 28 and November 26, 2019. Seedhead suppression ranged from 15% (application on November 1) to 82% (applied on September 4). Dates between September 4 and October 3 were the optimum application window for ethephon application on Innovation zoysiagrass as seedhead suppression was at least 62% with minimal turf injury occurring.
Aerification Effects On ‘Innovation’ Zoysiagrass Thatch And Quality, Jack Fry, Dani Mcfadden
Aerification Effects On ‘Innovation’ Zoysiagrass Thatch And Quality, Jack Fry, Dani Mcfadden
Kansas Agricultural Experiment Station Research Reports
When a thatch layer accumulates on turfgrass it can be detrimental to the stand. A field experiment was initiated to investigate aerification treatments and their influence on organic matter, quality, and color of ‘Innovation’ zoysiagrass that was sodded within the past year. Turfgrass that was intensely aerified had less organic matter content in the surface inch of the profile compared to turfgrass that was not aerified. Color was also enhanced in treatments receiving aerification compared to nonaerified turf, which may have been attributed to trending of higher nitrate content in aerified plots.

Kansas represents the northernmost region in the central United States where bermudagrass (Cynodonspp.) can be successfully grown as a perennial turfgrass. Historically, few cultivars that have both acceptable quality and adequate cold tolerance have been available to local growers. Because new introductions are continually being selected for improved hardiness and quality, both seeded and vegetative types need regular evaluation to determine their long-range suitability for use in Kansas.
Influence Of Herbicides And Irrigation On Tall Fescue Shoot And Root Growth, Dani Mcfadden, Jack Fry, Steve Keeley, Jared Hoyle
Influence Of Herbicides And Irrigation On Tall Fescue Shoot And Root Growth, Dani Mcfadden, Jack Fry, Steve Keeley, Jared Hoyle

When turfgrass stands are under renovation, a common problem is removing weeds prior to seeding because seedling turf does not emerge and compete well with weeds that are present. However, most herbicide labels recommend waiting for a defined period of time prior to seeding. If seeding is done prior to the date prescribed on the herbicide label, seed germination and seedling growth may be inhibited. A greenhouse study was conducted to determine the effects of irrigation prior to seeding on seedling growth after herbicide application. Overall, irrigation had no influence on the impact of herbicides on shoot or root growth …
Emergence And Growth Of Tall Fescue Seedlings After Postemergence Broadleaf Herbicide Application, Dani Mcfadden, Jack Fry, Steve Keeley

Effective weed control prior to seeding is essential for proper turfgrass establishment since competition from weeds can cause sward establishment to fail. Herbicides with multiple active ingredients from different chemical families could increase weed control efficacy, but hinder the establishment of newly seeded turf. Research trials were initiated in the fall of 2020 in Olathe and Manhattan, KS, to determine if tall fescue (Schedonorus arundinaceus) could be seeded earlier after application than stated on the herbicide labels. Overall, this study demonstrated that seeding between 0 to 14 days after an application of carfentrazone-ethyl + MCPP + 2,4-D + …
Laboratory Calibration Of The Spectrum Field Scout Tdr 300, W. Dyer, D. Bremer, P. Rossini, M. Stone, A. Patrignani

Soil moisture sensors (SMSs) are a useful tool that aid in data-driven water management decisions. However, default factory calibrations can be inaccurate and soil-specific calibrations are often required to obtain higher accuracy in the determination of soil water storage and plant available water. In this study, we conducted a lab calibration for the Field Scout TDR 300, which is a popular SMS used in the turfgrass industry. Five soils of different soil textural classes were packed in containers with known soil moisture for the laboratory calibration. The logarithmic model best fit the data for the course- and fine-textured soils, with …

Kansas Agricultural Experiment Station Research Reports
A set of 70 experimental zoysiagrass genotypes along with three standards, ‘Meyer,' ‘Innovation,' and ‘KSUZ 1201,' were evaluated for turf performance in the northern transition zone. The genotypes were previously selected from a set of 935 progeny that resulted from pairwise crossings of cold-hardy zoysiagrass parents with fine-textured, under-utilized zoysiagrasses. All 70 progeny survived the winter of 2019–2020 and thus were evaluated based on their turf performance. The preference of selection was based first upon spring green up ratings, followed by leaf texture (finer preferred), vigor, turf quality, and wilt during dry down. A total of 20 best progeny were …

Hemp is a broad term used to describe the many varieties ofCannabis sativaL. that produce less than 0.3% tetrahydrocannabinol (THC). The crop is globally significant, but only recently was allowed to be grown once again in the United States. Varieties have been selected and are currently grown with a wide cannabinoid profile. Cannabinoids are of high interest for their putative medical and therapeutic role in humans and companion pets. Cannabidiol (CBD) and THC are the two cannabinoids of primary interest. THC is of interest because it determines whether the final product is considered hemp (0.3% THC). CBD is …
