Different irrigation methods in wheat (Triticum aestivum L.) result in different water and nutrient use efficiencies and, ultimately, plant growth. A field experiment was conducted during the 2006–2007 and 2007–2008 crop cycles to investigate the effects of furrow irrigated raised bed planting and the effects of flood irrigated conventional planting on growth and productivity in winter wheat. In Zadoks Stages 5–31, wheat that was grown in raised bed planting suffered from a lower soil temp

Turf quality (TQ) decline due to drought is a major concern in cool-season turfgrass management. The study was conducted to examine whether selected Texas (TBG) x Kentucky bluegrass (KBG) hybrids (HBGs) (Poa arachnifera Torr. x P. pratensis L.) exhibit improved drought stress tolerance and recuperative ability in comparison to commonly-used KBG (P. pratensis) genotypes. Plant material included two HBG selections (HBG568 and HBG668), two commercially-available HBGs (‘Thermal Blue’ and ‘Band

Epidermal conductance (g_.min) is a measurement of water loss through the cuticle and stomata when stomatal conductance is minimal. Two pot experiments were conducted to evaluate genotypic variation in g_min for 10 to 12 rice cultivars (Oryza spp.) grown under flooded conditions. Epidermal conductance was estimated by measuring loss of water from the excised topmost fully-expanded leaves. Considerable genotypic variation in gmin was found. Two O. glaberrima cultivars had lowe

Maximum diurnal accumulation of soluble carbohydrates in warm-season grasses is an economic way of increasing hay quality; however, in the humid East, haymaking is difficult. This study evaluated gamagrass (Tripsacum dactyloides L.), topdressed with either 56 (LO) or 168 (HI) kg N ha–1, direct baled after mowing in the afternoon (PM/LO and PM/HI) or morning (AM/LO and AM/HI), wrapped with plastic film, and conserved as baleage. The four baleage treatments were evaluated by steers for dry matte

Received for publication November 3, 2008. Although land application of swine (Sus scrofa) manure lagoon effluent is a common and effective method of disposal, the presence of antibiotic-resistant bacteria, both pathogenic and commensal can complicate already understood issues associated with its safe disposal. The aim of this study was to assess antibiotic resistance in swine lagoon bacteria from sow, nursery, and finisher farms in the southeastern United States. Effluents from 37 lagoons were
