2017 National Turfgrass Evaluation Program Perennial Ryegrass Test: 2018 Data, Mingying Xiang, Jack Fry
Kansas Agricultural Experiment Station Research Reports
More than 100 entries of perennial ryegrass were evaluated in the perennial ryegrass National Turfgrass Evaluation Program (NTEP) study in Manhattan, KS, in 2018. A broad variation occurred among entries. Several entries consistently ranked in the top 10 in quality from month to month.
Thermal Imaging Detects Early Drought Stress In Turfgrass Utilizing Small Unmanned Aircraft Systems, Mu Hong, Dale J. Bremer, Deon Van Der Merwe
Thermal Imaging Detects Early Drought Stress In Turfgrass Utilizing Small Unmanned Aircraft Systems, Mu Hong, Dale J. Bremer, Deon Van Der Merwe
Kansas Agricultural Experiment Station Research Reports
Plots of fairway-height creeping bentgrass were watered differently to create a gradient of drought stress from severe deficit irrigation to well-watered, under an automatic rainout shelter in Manhattan, KS. Canopy temperature (Tc) measured by a small unmanned aerial system (sUAS) predicted drought stress approximately 5 days or more before drought symptoms were evident in either turfgrass visual quality (VQ) or percentage green cover (PGC). The ability of Tc to predict drought stress was comparable to the best spectral parameters acquired by sUAS on companion flights [i.e., near infrared (NIR) and GreenBlue VI], and slightly better than with spectral data obtained …
High And Low Management Input Regimes Result In Similar Net Carbon Sequestration Rates In Zoysiagrass Golf Course Fairway Turf, Ross C. Braun, Dale J. Bremer
High And Low Management Input Regimes Result In Similar Net Carbon Sequestration Rates In Zoysiagrass Golf Course Fairway Turf, Ross C. Braun, Dale J. Bremer
Kansas Agricultural Experiment Station Research Reports
This study was conducted from 2013–2016 to determine how irrigation and N fertilization may be managed to enhance carbon (C) sequestration in turf. In this study, the annual rate of change in soil organic carbon (ΔSOC) was measured under two management regimes, a high management input regime (HMI) and low management input regime (LMI), in a ‘Meyer’ zoysiagrass (Zoysia japonicaSteud.) golf course fairway.
Both management regimes maintained acceptable turf quality and at least 75% green cover during both summers. In both management regimes, soil organic carbon (SOC) increased after the 3.16-yr (1154-d) period indicating that C was sequestered …
Herbicide And Application Timing Effects On Windmillgrass (Chloris Verticillata) Control, Nicholas Mitchell, Jared Hoyle
Herbicide And Application Timing Effects On Windmillgrass (Chloris Verticillata) Control, Nicholas Mitchell, Jared Hoyle
Kansas Agricultural Experiment Station Research Reports
Windmillgrass (Chloris verticillataNutt.) populations commonly infest turfgrass systems in the midwest, which result in aesthetically unacceptable turfgrass stands. Research trials were initiated in 2017 and 2018, in Onaga and Junction City, KS, to determine windmillgrass control with various single herbicide applications at different application timings. Pylex (topramezone) resulted in more than 80% windmillgrass control 8 weeks after spring and summer application.
Influence Of Herbicide Combinations And Sequential Applications On Windmillgrass (Chloris Verticillata) Control, Nicholas Mitchell, Jared Hoyle
Influence Of Herbicide Combinations And Sequential Applications On Windmillgrass (Chloris Verticillata) Control, Nicholas Mitchell, Jared Hoyle
Kansas Agricultural Experiment Station Research Reports
Windmillgrass (Chloris verticillataNutt.) populations commonly infest turfgrass systems in the midwest, which result in aesthetically unacceptable turfgrass stands. Pylex (topramezone) and Acclaim Extra (fenoxaprop) have resulted in fair control of windmillgrass with single applications. For adequate control of windmillgrass, a sequential application of Tenacity (mesotrione), three weeks after the initial application, is recommended. Additionally, studies have shown the addition of triclopyr to HPPD inhibitor herbicides increases windmillgrass control in a controlled environment. Field experiments were initiated in 2018, at the Kansas State University Rocky Ford Turfgrass Research Center in Manhattan, KS, to determine the influence of herbicide combinations …
Winter Survival Of Experimental Bermudagrasses In The Upper Transition Zone, Mingying Xiang, Jack Fry, Yanqi Wu
Winter Survival Of Experimental Bermudagrasses In The Upper Transition Zone, Mingying Xiang, Jack Fry, Yanqi Wu
Kansas Agricultural Experiment Station Research Reports
A winter with very cold temperatures in 2017–2018 allowed for good separation of standard and experimental bermudagrasses for freezing tolerance. When evaluated in May 2018, survival of commonly used cultivars was: Tifway, 0%; Latitude 36, 20%; Northbridge, 25%. Some experimental progeny had up to 98% winter survival on the same rating date.

Evaluating Large Patch-Tolerant And Cold Hardy Zoysiagrass Germplasm In The Transition Zone, Mingying Xiang, Jack Fry, Megan Kennelly
Kansas Agricultural Experiment Station Research Reports
More than 2,800 zoysiagrass progeny, all having a single parent in common that exhibited tolerance to large patch, were evaluated in several transition zone states for quality characteristics and large patch tolerance. From these evaluations conducted over several years, 10 progeny have been identified for further evaluation that have good quality and large patch tolerance that is superior to Meyer zoysiagrass.
Minimal Water Requirements Of Cool-Season Turfgrasses For Survival And Recovery After Prolonged Drought, Mu Hong, Dale Bremer, Steve Keeley
Minimal Water Requirements Of Cool-Season Turfgrasses For Survival And Recovery After Prolonged Drought, Mu Hong, Dale Bremer, Steve Keeley
Kansas Agricultural Experiment Station Research Reports
Sodded tall fescue (TF) and Kentucky bluegrass (KBG) turfgrasses were exposed to prolonged drought at several levels of deficit irrigation from 0% to 50% of reference evapotranspiration (ET) within the first year of establishment. Tall fescue watered at 40% and 50% ET maintained minimally acceptable performance longer during the dry-down phases and recovered faster after rewatering than lower ET treatments. Tall fescue with no water input (0% ET) maintained minimally acceptable performance for about 5 weeks, which was longer than KBG watered at 50% ET, which remained acceptable for less than 3 weeks during the dry down. Although KBG watered …
