• I ybrid bermndagrasses are excellent performers in athletic fields because of their uniformity, traction, and tolerance to heat and wear. Unfortunately, every turfgrass species has its weaknesses. Although resistant to most disease problems, bermudagrasses are highly susceptible to the fungal disease spring dead spot. This disease annually causes widespread damage to berrnudagrass in athletic...

Reclaimed water (RW) is increasingly viewed as a valuable resource for supplying irrigation water and nutrients for landscape plants growing in urban environments. A greenhouse experiment was conducted to determine if nitrogen (N) in RW contributes significantly to turfgrass plant nutrition and to measure N use efficiency and the effects of irrigation with RW on N leaching. The factorial experi...

Perennial ryegrass is an important turf and forage grass in temperate regions worldwide. Limited genetic gains have been made with current breeding strategies compared other crops, such as rice maize, which benefit from Filial 1 (F1) hybrid breeding. One of the largest constraints on self-incompatibility preventing inbreeding, homozygous parental lines are required to develop hybrids maximal vi...

abstract in order to analyse of soil volume humidity and water potential of turf using of different amounts of water absorbent polymer in sort of acryl amid potassium, an experiment conducted at research farm of meybod azad university in 2005. the experiment was conducted in randomized completed block design in four levels of polymers of 3, 6, 12 and 24 gr/m2 and 0 gr/m2 of polymers was conside...

As restrictions on water use, fertilization, and pesticide applications continue to increase, golf course superintendents will need to use grass species that require reduced inputs. The objective of this study was to evaluate alternative turfgrass species under lowinput fairways conditions. In 2005, 17 species were established on native soil in St. Paul, MN. Each species was evaluated at three ...

Pathology challenges Turf nematodes are worm-like animals that are less than one-eighth of an inch long. Because they can't be seen by eye or hand lens, live hidden in the soil and cause no specific symptoms in turfgrasses, nematode damage goes unnoticed or is explained away to other problems, such as poor fertility, soil compaction, watering or diseases. The first symptom of nematode damage is...

CONTEXT Despite an increasing awareness of turf toe injury, confusion still exists regarding the anatomy, mechanism, diagnosis, and treatment of this hyperextension injury to the hallux metatarsophalangeal (MTP) joint. EVIDENCE ACQUISITION This article reviews the anatomy, diagnosis, and treatment algorithm for turf toe injury by reviewing relevant studies and presenting information useful to...

A lot of salt-affected soils in the world are also affected by compaction and waterlogging due to shallow water tables or decreased infiltration sodicity. Waterlogging cause reduced oxygen exchange (hypoxia). Research on combined impacts salinity hypoxia turfgrass growth is limited. The interactive effects availability nine perennial ryegrass entries (Lolium perenne L.) one alkaligrass [Puccine...
