This book was released on 1982 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field study with 5 tall fescue genotypes treated at the vegetative growth stage, with 0, 0.28, 0.56, and 0.84 kg/ha of mefluidide was initiated in July, 1980. The regrowth of these plants were again treated at the booting growth stage in April, 1981, with the same rates of mefluidide as in the first experiment. In addition, three rates of mefluidide (0, 0.28, and 0.56 kg/ha) were applied at the floral initiation stage of perennial ryegrass cv. Linn in March, 1981. Four varieties of tall fescue were transplanted from the field into 6-inch pots in February, 1981, and grown under 50/60°F and 70/80°F night/day temperature regimes in growth chambers. Mefluidide at the rate of 0, 0.28, and 0.56 kg/ha were applied at the pre-floral or at floral initiation growth stage. The same varieties were again transplanted from the field into 6-inch pots in April, 1981, and grown under the same temperature regimes and treated at pre-booting or at booting growth stage with the same rate of mefluidide as those in the first growth chamber experiment. Mefluidide interacted with tall fescue genotypes and also resulted in a reduction in dry matter yield, ADF (Acid Detergent Fiber) and increased CP (Crude Protein) content in both tall fescue trials in the field. The WSC (Water Soluble Carbohydrate) concentration was reduced by mefluidide applied at the vegetative growth stage in the first experiment, but it was increased at the booting growth stage application of mefludide on regrowth of these plants. Late applications of mefluidide did maintain forage quality of tall fescue with some elimination of dry matter yield reduction caused by earlier application. In perennial ryegrass cv. Linn, mefluidide reduced stem dry matter production, but did not affect leaf dry matter yield. This was accompanied by high leaf/stem ratios and retardation of plant height. Fertile tiller production was inhibited, accompanied by reduction in ADF, increased stem CP and increased WSC of leaf and stem tissue. Under the 70/80°F night/day temperature regime, all varieties produced a higher dry matter yield than plants under a 50/60°F night/ day temperature regime. However, WSC content of leaf and stem were higher in the low temperature regime. There were indications that mefluidide reduced ADF and WSC content of leaf and stem tissues, but increased leaf and stem CP under both temperature regimes in both experiments. This was accompanied by high leaf/stem ratios of treated plants.

Download or read book Evaluation of Species Composition by Four Methods on Two Perennial Grass Pastures Festuca Arundinacea Schreb and Lolium Perenne L Grazed Lightly and Heavily in Western Oregon written by Rafael Pessot Zorich and published by . This book was released on 1966 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study was undertaken to evaluate the seasonal botanical composition of two grass pastures, tall fescue (Festuca arundinacea Schreb.) and perennial ryegrass (Lolium perenne L.). Botanical composition was determined by four methods: dry-weight-rank, weight-estimate, hand separation, and the constituent differential, with cattle and sheep grazing at two intensities. The pastures were sampled eight times during the growing season (March 23-July 8), taking 50, 25, 5, and 5 observations with the dry-weight-rank, weight-estimate, hand separation, and constituent differential methods, respectively, using a 2.4-square-foot circular plot. New sets of multipliers had to be determined for the dry-weight-rank method. Three different ways of grouping the data were tested. Best results were obtained in both pastures when all the data were grouped from all grazing treatments, because no significant differences were detected among the experimental errors in the analyses of variance used to test data arrangements. Consequently, the use of only one set of multipliers was found to be more practical. The same ways of grouping the data were used to calculate the regression equations to give the most accurate correction for the weight-estimate method. Uncorrected data were also tested. It was determined that best results were obtained in the fescue pastures when all the data were grouped within each of the grazing treatments. In the ryegrass pastures, on the other hand, all data collected in each sampling period was found to be the best arrangement, provided that the number of observations is increased to compensate for greater pasture variability. An analysis of variance was run on the information obtained with each method in both pastures. It was concluded that, in the fescue sections, the methods gave similar results regardless of the kind of livestock, grazing intensity, and sampling period. Units grazed by cattle showed a lower fescue percentage, especially those heavily grazed, than those grazed by sheep; grazing intensity did not affect the trend of the fescue percentages in the mixture which declined as the season progressed. In ryegrass pastures, the ryegrass percentages obtained in each case were influenced by all four treatments: methods, kind of livestock, grazing intensity, and sampling periods. It is apparent from this study that the constituent differential method is the most promising one, and more attention should be directed to it in the future. A study is proposed to explore some of the factors influencing the use of the constituent differential method for determining production and botanical composition on mixed grass-legume pastures.
Download or read book Evaluation of Turf Type Intergeneric Hybrids of Lolium Perenne with Festuca Pratensis for Improved Stress Tolerance written by Brent D. Barnes and published by Proquest, UMI Dissertation Publishing. This book was released on 2012-10 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recurrent selection for drought and heat tolerance among hybrids of perennial ryegrass ( Lolium perenne L.) with meadow fescue ( Festuca pratensis Huds.), was used to develop turf-type populations with a marked increase in stress tolerance. Increased tolerance was associated with the presence of an introgression of F. pratensis chromatin on chromosome 3 of L. perenne . To determine if root characteristics were responsible for the improved stress tolerance, a greenhouse study was conducted to compare sister lines of Festulolium both with or without the introgression; the recurrent backcross parent; a representative F. pratensis ; and turf-type tall fescue ( Festuca arundinacea Schreb.) grown under well-watered conditions in 5.1-cm diam. x 160-cm long tubes containing sand. Two separate 120-day experiments revealed that F. pratensis produced deeper roots, more root biomass, and a higher root:shoot, while the industry standard, F. arundinacea , ranked at or near the lowest value. For the hybrids and ryegrass, the root parameters were intermediate between the 2 fescues, with no statistically significant difference among the 3 lines tested. The results indicate that in the tested Festulolium turf, drought and heat tolerance were not a consequence of increased root depth or root biomass as reported in previous reports for forage-type intergeneric hybrids of ryegrass and fescue.

Download or read book Control of Rattail Fescue Vulpia Myuros in Carbon seeded Kentucky Bluegrass and Perennial Ryegrass written by Raul Arroyo Rosas and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Controlling winter germinating weeds in fall planted turf grasses grown for seed in the Pacific North West (PNW) has become a challenge due to the lack of labeled herbicides and herbicide resistance. Rattail fescue (Vulpia myuros) is a problematic weed for grass seed growers due to the lack of effective herbicide treatments during establishment of Kentucky bluegrass (Poa pratensis) and perennial ryegrass (Lolium perenne). Due to the increased cases of diuron resistance, new alternatives to diuron are needed for stand establishment. In an effort to find new alternatives to diuron, a root growth assay was performed to identify the variation in species response to indaziflam prior to evaluating indaziflam and pyroxasulfone for the management of V. myuros in carbon-seeded P. pratensis (cv 'Dauntless') and L. perenne (cv 'Pillar', 'Playfast', or 'Prominent') at the USDA Central Ferry Farm and Cook Agronomy Farm near Pullman, WA. Mesotrione was included as an industry standard. Treatments of indaziflam and pyroxasulfone were applied PRE at planting and POST to 3-leaf stage turfgrass. In these studies, carbon-seeded turfgrass varieties were successfully established when using indaziflam (7.3, 14.6 g ai ha-1) and pyroxasulfone (89, 179 g ai ha-1) applied PRE. Crop safety was achieved by spraying a 2.5 cm wide band of activated carbon over the row at the time of planting. Vulpia myuros was controlled at the Central Ferry site, and populations were reduced at the Pullman site. Lolium perenne varieties germinated rapidly, grew vigorously and were strong competitors to weeds within the row. Lolium perenne varieties also showed better weed control within the bands than the P. pratensis variety due to slower to germination and establishment. The Poa pratensis variety 'Dauntless' had a slow germination rate and was slower to establish, and thus appeared to be less competitive with weeds in the row. These results suggest that using activated carbon during early establishment of turfgrasses grown for seed appears to be a safe and effective weed control technique when using indaziflam and pyroxasulfone to control invasive grass species.
