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...

Turfgrass growth, performance and quality are affected by abiotic stress factors and are of primary concern for persons managing turfgrass areas under seasonal tropical climates. Under these conditions, common Savannahgrass (SG) may have a performance advantage over imported hybrid turfgrasses. A greenhouse study was conducted to comparatively evaluate the performance of tropical turfgrasses ex...

in order to identify low maintenance turfgrass, turf quality of selected entries of germination stage under drought stress were evaluated by digital image analysis methods in the field conditions. the first greenhouse study examined the interaction of four different levels of soil water contents (40, 60, 80 % and 100% field capacity) on 14 festuca arundinacea entries. we determined the effects ...

The effects of water quality, installation depth and space of subsurface drip irrigation (SDI) laterals on yield and visual quality of turfgrass were investigated. A field experiment was conducted at the experimental farm of Shahrekord University. The experimental design was a Split-Split Plot with experimental arrangement of completely randomized block design with 16 treatments and three repli...

The current methods of turfgrass evaluations are often based on human-based assessment methods. However, eliminating subjective errors from such evaluations is often impossible. This research compared the accuracy of human-based and digital image processing-based methods for quality assessment of turfgrasses. Four turfgrass plots were evaluated using the two mentioned methods. In the human-base...

Application of biotic growth regulators (e.g. humic components) and appropriate mulches is recommended to improve turfgrass quality. However, limited research has investigated their effect on lawn establishment. To investigate the effect of humic acid and selected mulches on characteristics of Festuca arundinacea in its planting stage, a factorial experiment based on a completely rando...

Prosapia bicincta (Say) (Hemiptera: Cercopidae), the twolined spittlebug, is an economic pest of turfgrass in the southeastern United States. No data concerning natural enemies of P. bicincta in turfgrass have been reported previously. We compared predation of spittlebug eggs, nymphs, and adults in the laboratory by potential generalist predators commonly found in turfgrass: bigeyed bugs Geocor...

Turfgrass managers spend a significant amount of time monitoring their turfgrass fertility and irrigation programs to ensure the most efficient use of their resources while minimizing potential environmental impacts. Characterizing the spatial variability of nutrients across a golf course or large sports facility requires careful observation and periodic collection of soil and tissue samples. R...

Rationale Fungicide applications are a necessary practice to discourage disease development in most high quality turfgrass areas. Little is known, however, about the effects that fungicides have on resident microbial community of the soils supporting turfgrass sites. Soil bacteria are responsible for important processes including pesticide degradation, nutrient cycling, and organic matter break...
