Timely and accurate detection of above-ground herbage mass and the nutritive value of pastures can help the more efficient adjustment of stocking rate and determine the timing of protein supplements to be fed to livestock grazing these pastures. The objectives of this study were to determine seasonal variation in herbage mass, neutral-detergent fibre (NDF), aciddetergent fibre (ADF) and crude p...

Phosphogypsum is a byproduct of phosphate fertilizer production, and more than 700 million metric tons have accumulated on 2,500 ha in Florida. Field research was conducted to compare the benefits of capping phosphogypsum with overburden (up to 15 cm in depth) from mined sites versus treatment of the phosphogypsum with minimal amendments. After four growing seasons, vegetation cover was excelle...

Laboratory and digestion studies evaluated the nutritional value of the commercially available stargrass (Cynodon nlemfuensis Vanderyst var. nlemfuensis), 'Ona', two experimental stargrasses, 'Florona' and 'Florico', and the experimental bermudagrass 'Callie 35-3' (Cynodon dactylon). Ona and Florico stargrasses were also evaluated under grazing. Florico stargrass had the lowest concentration of...

Greenhouse studies were conducted to evaluate the sensitivity of three commercial cultivars, eight experimental cultivars and common bermudagrass to clethodim, glufosinate and glyphosate. Each herbicide was applied at eight doses. Data were regressed on herbicide dose using a log-logistic curve (R2 = 0.56-0.95 for clethodim, R2 = 0.60-0.94 for glufosinate, and R2 = 0.70-0.96 for glyphosate). Th...

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 ...

Melatonin (N-acetyl-5-methoxytryptamine) plays critical roles in plant growth and development and during the response to multiple abiotic stresses. However, the roles of melatonin in plant response to K+ deficiency remain largely unknown. In the present study, we observed that the endogenous melatonin contents in bermudagrass were remarkably increased by low K+ (LK) treatment, suggesting that m...

Background and objectives: Diabetes is a metabolic disease with hyperglycemia, decrease in insulin secretion or de-sensitization of peripheral cells to insulin.Onosmadichroanthum is a species of Boraginaceae and is used in traditional medicine for its anti-oxidant, anti-inflammatory and antibiotic properties, however data on its anti-diabetic effects ...

Bermudagrass (Cynodon dactylon) is one of tolerant grass species to drought and salt. The comparative analyses of bermudagrass in response to drought and salt stresses at the physiological, proteomic, and metabolomic levels were performed in this study. The physiological results indicated that osmolytes accumulation, ROS level and antioxidant enzyme activities were extensively changed by drough...
