The nutritional effects of sulla (Hedysarum coronarium L.) forage containing condensed tannins (CT) on growth of lambs, and carcass and meat quality were investigated. Thirty-two male Comisana lambs aged 100 ± 8 days weighing 19.0 ± 2.8 kg were fed fresh forage of sulla or CT-free annual ryegrass (Lolium multiflorum Lam. subsp. Wersterwoldicum) for 49 days until slaughter; in addition, each lam...

Field experiments were conducted in Virginia in 2000 and 2001 to investigate responses of wheat and diclofop-methyl-sensitive and –resistant Italian ryegrass to POST applications of several experimental and registered herbicides. The experimental herbicide combination AE F130060 03 was as effective as diclofop-methyl and more effective than chlorsulfuron plus metsulfuron, chlorsulfuron plus met...

Alternative forages can be used to provide valuable home-grown feed for ruminant livestock. Utilising these different forages could affect the manure value and the implications of incorporating these forages into farming systems, needs to be better understood. An experiment tested the hypothesis that applying slurries from ruminants, fed ensiled red clover (Trifolium pratense), lucerne (Medicag...

A single herbicide (Trimec or Strike 3 ) application in early season (March or April) was made to marginal areas around Þelds in 23-km test sites of the Mississippi Delta in 1999, 2000, and 2001. The herbicide was used to kill broadleaf weeds in the marginal areas that served as hosts for tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois). The herbicide treatment caused a signiÞcant r...

Phytoremediation technology has been widely used for the remediation of heavy metals in soil due to its favorable environmental and ecological effects, but establishing a single phytoremediation can result bottlenecks, such as long cycle, low biomass, difficulty root absorption. At present, inoculation with microorganisms that could assist plants their contaminated soils is attracting increasin...

Perennial ryegrass is a popular cool-season grass species due to its high quality for forage and turf. The objective of this study was to identify associations of candidate genes with growth and physiological traits to submergence stress and recovery after de-submergence in a global collection of 94 perennial ryegrass accessions. Accessions varied largely in leaf color, plant height (HT), leaf ...

An outbreak of annual ryegrass toxicity occurred on a Thoroughbred stud in Ceres in the Western Cape Province of South Africa. This is the 1st report of annual ryegrass toxicity in horses in South Africa, although the condition has been reported in cattle and sheep populations in the past. Annual ryegrass toxicity is characterised by a variety of neurological signs including tremors, convulsion...

The traditional New Zealand ryegrass/white clover based seasonal dairy farm system has remained unchanged for many years. Because pasture remains the predominant source of feed, increased milksolids (MS) production is dependent on growing or utilising more pasture. If the increased pasture growth from N fertiliser is discounted then increases in MS production have not occurred on our best dairy...

Water shortage worldwide mandates minimum use of irrigation water with maximumefficiency and productivity in all agricultural crops, landscape plants and turf. The objective inthis experiment was to study the effect of two levels of evapotranspiration-based (ETc) droughtin combination with two levels of nanosilicon dioxide (SiO2; NanSi1=1 mM and NanSi=2 mM),two levels of digoxin (Dig1=0.25 mg.l...
