Heavy metal pollution is a serious global environmental problem as it adversely affects plant growth and genetic variation. It also alters the composition and activity of soil microbial communities. The objectives of this study were to determine the soil microbial diversity, bermudagrass genetic variation in Cd contaminated or uncontaminated soils from Hunan province of China, and to evaluate C...

A 2-year greenhouse study was conducted at Clemson University, Clemson, S.C., in 2003 and 2004 to determine drought responses of six bermudagrass (Cynodon spp.) cultivars at four irrigation intervals. Cultivars selected from the 2002 National Turfgrass Evaluation Program Bermudagrass Trial were ‘SWI-1012’, ‘Arizona Common’, ‘Tift No.3’, ‘Tifsport’, ‘Aussie Green’, and ‘Celebration’. Treatments ...

Two experiments were conducted to compare corn, dried distillers’ grains (DDG), and pelleted soybean hulls (SH) as supplements for cattle grazing bermudagrass. In Exp. 1, 66 crossbred steers (306 ± 3.2 kg) were stratified by weight and allotted randomly to six 2.4-ha bermudagrass pastures for a 107-d study. One of three supplement treatments (corn, DDG, or SH) was assigned randomly to each past...

that ‘Coastal’ hybrid bermudagrass receiving 670 kg N ha 1 and 153 kg P ha 1 from swine effluent removed Five warm-season annual grasses were compared for dry matter an average of 382 kg N ha 1 yr 1 and 43 kg P ha 1 yr 1. (DM) yield and nutrient uptake alongside bermudagrass [Cynodon dactylon (L.) Pers.] on a Brooksville silty clay (fine, montmorillonitic, Adeli and Varco (2001) found that ‘Ali...

Drought stress is one of the crucial factors affecting plant growth and development in turfgrass species, especially during summer season. Exogenous regulators are an effective convenient approach to mitigating adverse effects drought on growth. The objectives this study were reveal exogenous carnosine or chitosan turf performance physiological indexes bermudagrass (Cynodon transvaalensis × C. ...

Mature weight and rate of maturing were estimated in 177 Angus, Brahman, and reciprocal-cross cows grazing bermudagrass or endophyte-infected tall fescue over a 4-yr period to evaluate genotype x environment interactions. Data were collected every 28 d until cows were approximately 18 mo of age and then at prebreeding, postcalving, and weaning of calf. All cows with weight data to at least 42 m...

The objective of this study was to examine the effects of Aspergillus oryzae fermentation extract on the in vitro equine cecal fermentation of soluble starch, amino acids/peptides, coastal bermudagrass hay, and alfalfa hay. Cecal contents were obtained from a cecally fistulated Quarter Horse gelding fed coastal bermudagrass and grain (70:30) either unadapted or adapted to dietary A. oryzae supp...

OBJECTIVE To evaluate the seasonal influence, signalment, type of hay consumed, clinical examination findings, and outcome after surgery for horses with ileal impaction. STUDY DESIGN A retrospective study. RESULTS Between 1988 and 1993, 28 horses had surgical correction of ileal impaction. There was a significantly higher rate of ileal impaction during the Fall (September-November, P = .004...

ent management are important steps in increasing uptake of soil-available P and reducing P losses in runoff Haying common bermudagrass [Cynodon dactylon (L.) Pers.] is (Rowe and Fairbrother, 2003; Sharpley and Halvorson, commonly used to manage field-applied manure P in the southeastern 1994). Utilizing this manure resource by replacing comUSA but is limited to summer. This 3-yr study was done ...

Mite infestations are widely recognized as reducing the growth of affected warm-season turfgrasses. This observation is, however, a qualitative assessment, albeit based on extensive field observations over past >60 yr, and level reduced has never previously been quantified. In three replicated pot experiments, dry matter production hybrid bermudagrass [Cynodon dactylon (L.) Pers. × Cynodon tran...
