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...

Turf grasses are considered an integral part of landscape ecological systems worldwide which provide functional, recreational and aesthetic benefits to society and the environment. In arid and semiarid regions (e.g., Mediterranean region), turf grass is usually grown under harsh and unfavorable growing conditions with low rainfall and high rates of evapotranspiration as well as in soils with nu...

crested wheatgrass (agropyron cristatum (l.) gaertner.) is a potential source of low-maintenance turf species for use in areas with less water. the main goal of this study was to evaluate turf quality characteristics of 24 crested wheatgrass specimens collected from different locations of iran as low-maintenance turfgrass. the experimental design was a randomized complete block design with 3 re...

Lawns are ubiquitous in the American urban landscapes. However, little is known about their impact on the carbon and water cycles at the national level. The limited information on the total extent and spatial distribution of these ecosystems and the variability in management practices are the major factors complicating this assessment. In this study, relating turf grass area to fractional imper...

Pesticides associated with the turfgrass industry have been detected in storm runoff and surface waters of urban watersheds, invoking concern of their potential environmental effects and a desire to reduce their transport to nontarget locations. Quantities of chlorpyrifos, dicamba, dimethylamine salt of 2,4-dichlorophenoxyacetic acid (2,4-D), flutolanil, and mecoprop-p (MCPP) transported in run...

water salinity and drought are the major abiotic stresses limiting turf grass growth. on the other hand, shortage of waterresources and salinity of water and soil in the arid and semi-arid zones such as iran, are the restricting factors in developinglawn turf grasses. an experiment was conducted to evaluate the combined effects of water salinity and deficit irrigation ontall fescue (festuca aru...

Land and water resources are becoming scarce and are insufficient to sustain the burgeoning population. Salinity is one of the most important abiotic stresses affecting agricultural productions across the world. Cultivation of salt-tolerant turfgrass species may be promising option under such conditions where poor quality water can also be used for these crops. Coastal lands in developing count...

We examined the effects of supplemental food sources on parasitism of turf-infesting white grubs (Coleoptera: Scarabaeidae) by tiphiid wasps (Hymenoptera: Tiphiidae). Survival of spring active Tiphia vernalis Rohwer and late summer active Tiphia pygidialis Allen, parasitoids of Japanese beetle, Popillia japonicaNewman, andmasked chafer,Cyclocephala spp., grubs, respectively, was signiÞcantly in...
