Download or read book The Effect of Trinexapac Ethyl and Three Nitrogen Sources on Creeping Bentgrass Agrostis Stolonifera Grown Under Three Light Environments written by Edward John Nangle and published by . This book was released on 2008 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Shade stress on creeping bentgrass (Agrostis stolonifera) causes elongation of leaves, reduced energy availability for growth and lower levels of disease resistance resulting in poor quality putting surfaces. Decreased quantity or photosynthetic photon flux density (PPF) and quality or the red:far red light ratio (R:FR) of light affects the morphology of turfgrass plants by increasing production of giberellic acid and reducing available non-structural carbohydrates. The object of the study was to determine which source of nitrogen (N) is best suited to retaining turfgrass quality in shade and to see if the plant growth regulator trinexapac-ethyl [4-(cyclopropyl-[alpha]-hydroxy-methylene)-3,5-dioxo-cyclohexane carboxylic acid ethyl ester] (TE) (Syngenta AG, Switzerland) can improve density and combat the loss of surface quality of bentgrass under tree shade. Field studies were conducted on 'Penncross' creeping bentgrass (Agrostis stolonifera) in Columbus, in 2006, and 2007. Under three light environments: full sun (FS), reduced R:FR (DS), and reduced PPF (NS). Light reduction was>90% in both shade areas and the R:FR ratio was .38 in the DS area, 1.28 in NS, and 1.29 in FS. The three N treatments included (NH2)2CO, Ca(NO3)2 and (NH4)2SO4 foliarly applied weekly at a rate of 0.43g m-2 with or without TE applied bi-weekly at 0.3975 L ha-1. Chlorophyll content, along with non-structural carbohydrates, flavonoids, turf canopy color, dry matter and canopy densities were measured. There were no differences in soluble carbohydrate levels between treatments. Chlorophyll levels varied between TE treated and non-treated areas. Applications of (NH2)2CO consistently resulted in higher content of N15 in turfgrass plants also but there was no effect in nitrogen uptake kinetics due to light environment differences. TE had a negative impact on quantities of flavonoids. There was variation between the N treatments in relation to dry matter and carbohydrate content. (NH2)2CO in combination with TE provided the best visual quality surface as the season progressed. TE was effective in reduced PPF conditions and R:FR conditions which would indicate it as a possible product for use in shade management of creeping bentgrass Agrostis stolonifera. It was equally efficient in both light environments suggesting that prior shade research using NS is relevant to shade management in private industry. There was not a strong indication as to a preferred source of N.(NH2)2CO had positive impacts on total chlorophyll content.

Download or read book Turfgrass written by John C. Stier and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 1348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability is a key framework for analyzing biological systems—and turfgrass is no exception. It is part of a complex that encompasses turfgrass interactions with different environments and the suitability of different turfgrasses for specific environments. In addition to its biological role, turfgrass—in the form of lawns, green spaces, and playing surfaces—brings beneficial sociological effects to an increasingly urbanized society. This book presents a comprehensive overview of current knowledge and issues in the field of turfgrass research and management, including the genetics and breeding, the diseases and pests, and the ecology of turfgrasses, and will appeal to a broad spectrum of readers.

Available in PDF, EPUB and Kindle. Book excerpt: Precision conservation is a reality, and we are moving towards improved effectiveness of conservation practices by accounting for temporal and spatial variability within and off field. This is the first book to cover the application of the principles of precision conservation to target conservation practices across fields and watersheds. It has clearly been established that the 21st century will present enormous challenges, from increased yield demands to climate change. Without improved conservation practices it will not be possible to ensure food security and conservation effectiveness. Readers will appreciate the application of the precision conservation concept to increase conservation effectiveness in a variety of contexts, with a focus on recent advances in technology, methods, and improved results. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.
