In recent decade, establish and maintenance of turf grasses is faced with serious doubts due to reduction of precipitation and water resources. So, identification of drought-resistant native and rangeland species, and introducing them as turf grass not only is effective in reducing water consumption, but also help to preserve the genetic resources of the country. In order to evaluate the usabil...

Studies examined the possibility that mixtures of endophytic perennial ryegrass and Kentucky bluegrass provide resistance against larvae of the black cutworm, Agrotis ipsilon (Hufnagel). We hypothesized that resistance against A. ipsilon in such stands would stem from the influence of Kentucky bluegrass on A. ipsilon growth and behavior rather than the influence of endophytic perennial rvegrass...

Ryegrass is a highly nutritious grass that can be utilized for grazing or production of baleage, haylage, or hay. In contrast to many regions of the world that are suitable for production of perennial ryegrass, annual ryegrass varieties are best suited for use in the Southeast US. When properly managed, annual ryegrass provides moderate concentrations of degradable protein. Annual ryegrass is h...

The effects of soil water deficit and interspecific plant interaction were studied on the dry matter (DM ) yield of white clover and ryegrass and on the morphogenesis of white clover. Plants were grown either: (1) individually (no interaction); or in a mixture of equal plant numbers with either (2) just shoot interaction, or (3) both shoot+root interaction. Plants were subjected to soil water d...

Remediation of soils contaminated with petroleum is a challenging task. Four different bioremediation strategies, including natural attenuation, biochar amendment, phytoremediation with ryegrass, and a combination of biochar and ryegrass, were investigated with greenhouse pot experiments over a 90-day period. The results showed that planting ryegrass in soil can significantly improve the remova...

protein-rich hydrolysate from feather waste was obtained using a mixed culture of selected thermophilic actinomycete strains, and was tested for possible application as soil amendment and biological control agent. for this purpose, a 4 months laboratory experiment was carried out using two types of urban soils (sofia, bulgaria): native park soil and anthropogenic soil. the effect of the obtain...

Perennial ryegrass (Lolium perenne) is an important forage grass with high yield and superior quality in temperate regions which is widely used in parks, sport field, and other places. However, perennial ryegrass is moderately tolerant to salinity stress compared to other commercial cultivars and salt stress reduces their growth and productivity. Aspergillus aculeatus has been documented to par...

Turfgrass is one of the important components of ornamental plant in the construction of parks and landscapes so that the purpose of this study was to investigate the influence of type and different concentrations of Copper, Zinc and Cobalt on germination and seedling growth of perennial ryegrass (Lolium perenne L.) and red fescue (Festuca rubra L.) seeds in in vitro conditions. This study was c...

Groups of six to nine Merino Summary lambs were weaned in September (May drop) and December (September drop) on to three types of irrigated perennial pastureperennial ryegrass (Lolium perenne), Ladino white clover (Trifolium repens) and lucerne (Medicago sativa), and one irrigated annual pasture-subterranean clover ( Trifolium subterraneum) . The weight gain of the weaners on white clover was s...
