Abstract Industrial‐scale coffee ground waste has the potential to serve as a nutrient‐rich soil amendment, which would offer growers an opportunity reduce applications of traditional fertilizers. Composted spent grounds (CSCGs) and noncomposted (NCSCGs) were evaluated for their organic N Nitrogen mineralization NCSCGs CSCGs was compared commonly used synthetic fertilizers: urea Milorganite. Net microbial activity measured in fine sandy loam field at 25°C 60% water holding capacity weekly...
The influence of deciduous foliage shade on turfgrass development has not been fully investigated. Previous research neglects changes in spectral distribution, e.g., red:far‐red light (R:FR) ratios common shade. Turfgrass plants may respond simultaneously but different ways to intensity and composition. A field study was conducted 2001–2002 at the Ohio Research Educational Facility, Columbus, OH. Two tall fescue ( Festuca arundinacea Schreb.) cultivars differing tolerance were established...
A 3-year study was conducted to evaluate the comparative performance of zoysiagrass ( Zoysia spp .) cultivars for shaded environments in which inputs are minimized. Included were commercial Diamond, Cavalier, Royal, Shadow Turf, Zorro, Zeon, Jamur, Crowne, Palisades, and Meyer. In July 2006, grass plugs planted a shade nursery comprised live oak trees providing 89% shade. From 2007 2009, turf plots periodically evaluated quality, density, color, vertical canopy height, extent lateral spread....
ABSTRACT Municipal water restrictions have become commonplace throughout much of the southern United States. The objectives this 2‐yr study were to (i) determine supplemental irrigation requirements necessary for achieving acceptable quality in 15 zoysiagrass ( Zoysia japonica and matrella ) bermudagrass Cynodon ssp.) cultivars when managed under a 2 d/wk frequency, (ii) effects mowing height on requirements, (iii) evaluate root development differences between species at completion study. A...
Golf course water use continues to be highly scrutinized. Information is limited regarding minimal levels of reference evapotranspiration (ET o )‐based irrigation needed maintain adequate summer fairway performance and autumn recovery. The objectives this 2‐yr study were (i) characterize ‘Tifway’ bermudagrass [ Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy] response 0.6, 0.45, 0.3, 0.0 ET o, with without simulated traffic (ii) evaluate effects on recovery at full levels. Without...
As population growth and demands for potable water increase, use of low-quality or effluent sources irrigation is becoming more prevalent. Because these often contain elevated levels dissolved salts, turfgrasses must increasingly possess mechanisms coping with salinity stress. The objectives this research were to utilize Scanning Electron Microscopy (SEM) combined Energy Dispersive X-ray Spectroscopy (EDS) explore characterize anatomical physiological responses four salinity-tolerant...
Irrigated agriculture is the largest user of water in Texas, followed by urban-municipal uses, which has landscape irrigation as its component. Data from various sources were used to estimate extent state’s urban landscaped area and associated use. The statewide golf courses estimated at 115,000 acres, while 1,608,399 acres are ascribed managed landscapes lawns. While total annual use 0.364 million acre-feet, volume projected for sector ranges a low 1.898 acre-feet high 4.021 acre-feet. sum...
Phoma macrostoma is a bioherbicide being developed for selective weed control in turfgrass. The previous research with this product limited to cool-season turfgrass systems little information available on appropriate application rates or spectrum weeds common warm-season turf. Studies were conducted evaluate and of P. dandelion (Taraxacum officinale G.H. Weber ex Wigg.), slender aster (Aster subulatus var. ligulatus Shinners), mallow (Malva neglecta Wallr.), purslane (Portulaca oleracea L.),...
Resolution of the effects trinexapac-ethyl and nitrogen (N) application rate on evapotranspiration low-cut, prostrate turfgrass species such as creeping bentgrass ( Agrostis stolonifera L.) hybrid bermudagrass [ Cynodon dactylon (L.) Pers. × transvaalensis Burtt-Davy] has not been explored. This study sought to examine integrated growth responses these two N rates trinexapac-ethyl, a commonly used growth-regulating compound for suppressing shoot growth. ‘Penncross’ ‘Tifdwarf’ were studied....
'DALSA 0605' (Reg. No. CV-274, PI 671959) is an embryo rescue-derived interploid hybrid of St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] resulting from a cross between TAES 5382 (African triploid 291594) and 'Palmetto' (diploid). DALSA 0605 was evaluated under the designation 5471-18 TXSA 19 approved for release as new cultivar by Texas A&M AgriLife in 2014. vegetatively propagated, genetically stable, uniform cultivar. It distinguished other cultivars traits characteristics...
Abstract Estimation of genotype‐by‐environment interaction (GEI) is important in breeding programs because it provides critical information to guide selection decisions. In general, multienvironment trials exhibit heterogeneity variances and covariances at several levels. Thus, the objectives this study were (a) find best genetic covariance matrix model GEI compare changes genotypic rankings between structure against a compound symmetry structure, (b) define mega‐environments for turfgrass...
ABSTRACT Pressures to protect water quality and shortages are leading increased applications of effluent on turfgrasses, there pressures disperse throughout the year. These experiments investigated NO 3 − uptake efficiency by Tifway bermudagrass [ Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy] during growth dormancy cycles, thus potential filter at different times Turf–soil cores from field plots were placed in controlled environment chambers fed solutions with 15 N‐NO Nitrate...
Abstract In breeding programs, superior parental genotypes are used in crosses to generate novel genetic variability for new selection cycles. Genotypes usually more adapted environments where the program is located, since selections performed under specific agroecosystems. Thus, objective of this study was evaluate performance bermudagrass ( Cynodon Rich. species), St. Augustinegrass [ Stenotaphrum secundatum (Walter) Kuntze], seashore paspalum Paspalum vaginatum Sw.), and zoysiagrass...
The growing popularity of cold-brewed coffee has resulted in large amounts localized spent grounds (SCG) generated from production plants. Spent offer many favorable agronomic properties, but also contain caffeine, tannins and phenolic compounds that may be deleterious to plant growth. There is a body research examining the effects SCG on plants, little which pertains use turfgrass systems. objective this two-year field study was evaluate feasibility using as an source nutrients for...
Previous research on the potential of gibberellin inhibiting growth regulator trinexapac-ethyl (TE) [4-(cyclopropyl-α-hydroxy-methylene)-3,5-dioxocyclohexanecarboxylic acid ethyl ester] to improve quality and density shaded turfgrass has been conducted under neutral-density shade. However, some phytochrome-mediated responses turfgrass, such as tillering, are different deciduous shade versus The objectives this study were investigate 1) whether TE would result in improved stand grown observed...
Effective water conservation in the landscape requires identification of cultural management practices that maximize genetic rooting potential establishing turfgrass sod. Nitrogen is critical for successful establishment; however, there has recently been debate over whether to restrict N fertilization during summer periods parts Florida and United States. This study was undertaken examine within four warm‐season species, relative influences cutting height fertility on (i) rate root extension...
