There has been some transition to using low-input fine fescues on golf courses, but these species have poor traffic tolerance and divot recovery, making them impractical for playable areas courses. The objectives of this study were determine the effect plant growth regulator (PGR) trinexapac-ethyl performance fescue mixtures when managed as a course fairway identify that perform well under stre...

Fine fescue taxa differ in their field establishment rate but it is unclear if this due to differences germination or seedling growth rate. Research at Purdue University quantified seed morphology, vigor, and vigor among 30 cultivars of fine (FF) (Festuca spp.). Strong creeping red (STCRF) rubra ssp. rubra), slender (SLCRF) (F. littoralis), Chewings commutata), hard brevipila), sheep ovina) wer...

Figure 1. Racomitrium heterostichum mostly imbedded in ice while some branches are free and available for photosynthesis. In general, bryophytes seem able to withstand cold in the leafy state much better than their tracheophyte counterparts. Ochi (1952) found that most mosses (18 species tested) were resistant to cold to-20°C. Seven of these species were resistant to-27°C. He was unable to find...

Amaç: Bu çalışma farklı tuz dozları (kontrol/0, 50 mM, 100 150 mM ve 200 mM) altında bazı çim türlerinin (Festuca arundinaceae L. (kamışsı yumak), Festuca rubra subsp. (köksaplı kırmızı yumak) commutata (adi yumak)) performaslarını belirlemek için yürütülmüştür. Yöntem Bulgular: Çalışmada dozlarını oluşturmak NaCl2 kullanılmıştır. Tuz dozlarına göre hazırlanan solüsyonlar çimlenme ortamına 8 mL...

Little information exists on establishment vigor differences among fine fescue taxa (Festuca L. spp.) and the effects N fertilizer levels or clover (Trifolium spp.)-inclusion during establishment. Five replicated field experiments in Indiana, Minnesota, Oregon were conducted from 2019 to 2021. Data collection continued for 9 mo after planting investigate four determine optimal fertility clover-...

In 2018–2019, establishment problems were encountered, after reseeding creeping bentgrass (Agrostis stolonifera) on a sand-based putting green ice encasement at the NIBIO Turfgrass Research Center, Norway. Seeds germinated, but seedlings attained purple color and died in large patches. Replacement of top 3 cm layer with new sand amended Sphagnum peat or garden compost did not solve problem. To ...

Pelargonic acid is a non-selective post-emergence contact bio-herbicide which registered both for cropping and non-cropping uses in several countries. Dose–response curves on the efficacy of pelargonic against common weeds Mediterranean areas are not available. summer winter annual were evaluated two field experiments (winter exp. 2019 2020) central Italy. was applied at five doses (1.4, 2.7, 5...

Research is required on sod to explore the differences in management and postharvest practices help inform producers reduce information inefficiencies that affect supply demand of cool-season turfgrass sod. Replicated field experiments were conducted Indiana Minnesota quantify effect species (strong creeping red fescue [Festuca rubra L. ssp. Gaudin], Chewings [F. commutata tall arundinacea Schr...

Abstract The lack of turfgrass diversity in cool‐season sod production is related to information inefficiencies, such as the agronomic available on improved, low‐input species, fine fescues ( Festuca spp.). Collaborative research between Purdue University and Minnesota investigated influence species mixtures harvest (production strength) storage limitations sod. Field experiments were establish...
