Large (>1600 microm), ingestively masticated particles of bermuda grass (Cynodon dactylon L. Pers.) leaf and stem labelled with 169Yb and 144Ce respectively were inserted into the rumen digesta raft of heifers grazing bermuda grass. The concentration of markers in digesta sampled from the raft and ventral rumen were monitored at regular intervals over approximately 144 h. The data from the two ...

Unlike most other agronomic crops, the selection of a bermudagrass cultivar is a long-term commitment. Bermudagrass is a warm-season perennial grass that can persist and withstand the rigors of grazing and hay production for decades. Establishing it, however, is a significant investment that pays off over the long-term. It is important to understand the characteristics of the different cultivar...

The effect of formulation and adjuvants on absorption and translocation of C-clethodim was determined at 1, 4, 12, 24, 48, and 72 h after treatment (HAT) in bermudagrass under greenhouse conditions. Absorption of C-clethodim with the 0.12 kg L (15 to 85%) formulation was higher than with the 0.24 kg L (5 to 40%) formulation, regardless of presence or absence of adjuvant. There was considerable ...

Spectral reflectance data originating from Unmanned Aerial Vehicle (UAV) imagery is a valuable tool to monitor plant nutrition, reduce nitrogen (N) application to real needs, thus producing both economic and environmental benefits. The objectives of the trial were i) to compare the spectral reflectance of 3 turfgrasses acquired via UAV and by a ground-based instrument; ii) to test the sensitivi...

Weeds are commonly found in bermudagrass turf during the winter and early spring throughout the Southeastern United States whether this turf is used for lawns, parks, athletic fields or golf courses. Mild winter temperatures favor rapid growth of these annuals. When bermudagrass goes dormant in the fall after the first killing frost, it does not compete with germinating winter weeds. Bermudagra...

Hybrid bermudagrasses occasionally suffer significant damage when below-normal winter conditions occur. In an attempt to enhance cold tolerance of these grasses, a study was undertaken to assess the effects of late-season nitrogen (N) fertilization and applications of the growth regulator trinexapac-ethyl (Primo) on morphology and cold tolerance of ‘Tifton 419’ hybrid bermudagrass. Nitrogen app...

Coastal Bermuda grass (CBG) has been shown to have potential as a biomass feedstock for sugar production. In this study, the effectiveness of ozone pretreatment for CBG to improve the sugar recovery via enzyme hydrolysis was investigated. Raw CBG and autohydrolysistreated CBG were pretreated with ozone at ozone consumption of 1.8 to 26.4 % (w/w) at room temperature. Lignin degradation and hemic...

Facilitative interactions between neighboring plants can influence community composition, especially in locations where environmental stress is a factor limiting competitive effects. The longleaf pine savanna of the southeastern United States is a threatened and diverse system where seedling recruitment success and understory species richness levels are regulated by the availability of moist mi...

Effects of supplemental Bermuda grass hay (BG) or ground corn on intake, digestion and performance of cattle consuming endophyte-infected fescue (I) were studied. In Exp. 1, a Latin square study, five growing Holstein steers (158.1 kg) consumed I ad libitum and were offered 0, .3, .6, .9 or 1.2% body weight (BW) of BG daily. Total dry matter (DM) intake rose linearly (P less than .05) with incr...
