2021-2022 Kansas State University Industrial Hemp Cannabidiol (Cbd) Research Report, Jason Griffin
Kansas Agricultural Experiment Station Research Reports
Hemp is a broad term used to describe the many varieties of Cannabis sativa L. 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 …
Aerification Effects On ‘Innovation’ Zoysiagrass In 2020–2022, Dani Mcfadden, Jack D. Fry
Aerification Effects On ‘Innovation’ Zoysiagrass In 2020–2022, Dani Mcfadden, Jack D. Fry
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 thatch (organic matter level), 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 non-aerified turf, which may have been attributed to the trending higher nitrate content in aerified plots. Moderately aerified turf significantly increased rooting …
Effects Of Glyphosate Applied At Different Times On Dormant Zoysiagrass Cultivars In The Transition Zone, Dani Mcfadden, Jack D. Fry
Effects Of Glyphosate Applied At Different Times On Dormant Zoysiagrass Cultivars In The Transition Zone, Dani Mcfadden, Jack D. Fry
Kansas Agricultural Experiment Station Research Reports
Winter annual weeds become a major problem during winter dormancy in warm-season turfgrass stands. In the transition zone, a winter glyphosate application is a common practice to reduce winter annual weed competition in zoysiagrass before emerging from dormancy in the spring. Research was conducted on the effects of glyphosate application timings on spring greenup and quality of experimental zoysiagrass genotypes compared to commercially available cultivars. Preliminary data from this study revealed a quicker spring greenup when glyphosate was applied in November compared to March. However, March-applied glyphosate significantly reduced cool-season weeds in experimental plots and enhanced quality compared to the …
2019 National Turfgrass Evaluation Program Bermudagrass Test: 2022 Data, Linda R. Parsons, Jason Griffin
2019 National Turfgrass Evaluation Program Bermudagrass Test: 2022 Data, Linda R. Parsons, Jason Griffin
Kansas Agricultural Experiment Station Research Reports
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.
Herbicide Effects On Establishment Of Zoysiagrass From Sprigs In Two Consecutive Years, Dani Mcfadden, Jack D. Fry
Herbicide Effects On Establishment Of Zoysiagrass From Sprigs In Two Consecutive Years, Dani Mcfadden, Jack D. Fry
Kansas Agricultural Experiment Station Research Reports
Weed control after planting warm-season grasses in the spring can be critical for acceptable establishment of the stand. However, many herbicide labels can be unclear on sprigging restrictions before or after the application of a product. Research was conducted on the growth effects of pre- and postemergence herbicides applied at or near the day of ‘Innovation’ zoysiagrass sprigging. Preliminary data from this study showed granular (Ronstar G) and liquid (Ronstar Flo) formulations of oxadiazon caused the least amount of injury to zoysiagrass.
