This book was released on 2005 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Creeping bentgrass (Agrostis stolonifera L.) is grown on golf course putting greens and its use as fairway turf is becoming more common. Creeping bentgrass cultivars tolerant to the herbicide glyphosate [N-(phosphonomethyl)glycine] have recently been developed. The ability to control weeds by the application of a nonselective herbicide, such as glyphosate, would ease overall turfgrass management. The conversion of existing putting greens and fairways to glyphosate-resistant creeping bentgrass is an option that many golf course superintendents are likely to consider. However, the conversion of existing turf to a more desirable species or cultivar is costly and would require the golf course to close for a considerable period of time. The objective of these field experiments was to speed the conversion of previously established putting greens and fairways to glyphosate-resistant creeping bentgrass. The best timing for glyphosate application to remove competition from existing grasses was researched on existing putting greens and fairways. Research was also conducted to study the effect of the following factors on conversion of existing putting greens to glyphosate-resistant creeping bentgrass: (i) seeding date, (ii) seeding rate, (iii) surface preparation method, (iv) mowing practices after seedling germination, and (v) N fertility. The best timing for glyphosate application to remove competition from existing turf was before seeding or shortly after seeding. Golf course putting green conversion to glyphosate-resistant creeping bentgrass was most rapid when seed was sown in late summer at 7.3 g m−2. All surface preparation methods resulted in similar turf cover, but some methods were less labor-intensive and caused less disruption to the putting green surface. Putting green conversion was most rapid when seedlings were mowed for the first time at 6.4 mm and glyphosate-resistant creeping bentgrass was permitted to reach approximately 100% cover before lowering the mowing height at a rate of 0.76 mm wk−1. No differences were observed between N fertility rates of 1.2 and 2.4 g m−2 wk−1. The results of these experiments suggest that successful conversion of golf course turf to glyphosate-resistant creeping bentgrass can occur with minimal interruption to golf play.

Available in PDF, EPUB and Kindle. Book excerpt: Pollen transmits the male genetic material in sexual reproduction of all higher plants. This same pollen is also well suited as a research tool for studying many patterns of plant and animal metabolism. In addition, an increased knowledge of pollen may help plant breeders accelerate efforts to improve the world's food and fiber supply. This volume focuses upon pollen biology and chemistry; it attempts to inte grate these facts with management practices involved in pollen applications. People have long been involved with pollen. Pollen applications are recorded in the rites of ancient civilizations (see Frontispiece). From the earliest times many benefits have been attributed to the inclusion of pollen in man's diet; also, since the mid-19th century air-borne pollen has been recognized as detrimental to many people's health. Disciplines concerned with man's cultural history and the earth's changing ecology find pollen a particularly useful and accessible tool. Identifiable parts of pollen have survived over 100 million years. But most books dealing with pollen are generally concerned with the identification of the plant source, an aspect of the science of palynology; other books emphasize the natural vectors transmit ting pollen, the pollination mechanisms. Very few works include the biochem istry or biology of pollen. Yet extensive studies by physicians, as well as plant breeders and apiculturists, have contributed a sizeable body of research relating to pollen.

Download or read book Growing Plantation Forests written by P. W. West and published by Springer Science & Business Media. This book was released on 2013-10-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the scientific principles that are used throughout the world to ensure the rapid, healthy growth of forest plantations. As the population of the world increases so does the amount of wood people use. Large areas of natural forests are being cleared every year and converted to other uses. Almost as large an area of plantation forests is being established annually to replace those lost natural forests. Eventually, plantations will produce a large proportion of the wood used around the world for firewood, building, the manufacture of paper and bioenergy. Forest plantations can also provide various environmental benefits including carbon storage, rehabilitation of degraded land, serving as disposal sites for various forms of industrial or agricultural waste and enhancing biodiversity in regions that have been largely cleared for agriculture. Whatever their motivation, plantation forest growers want their plantations to be healthy and grow rapidly to achieve their purpose as soon as possible. This book discusses how this is done. It is written for a worldwide audience, from forestry professionals and scientists through to small plantation growers, and describes how plantations may be grown responsibly and profitably.

Generously supplemented with 300 drawings, photographs, andtables, Weed Science is an essential book for students taking anintroductory course in weed science, as well as a reference foragricultural advisors, county agents, extension specialists, andprofessionals throughout the agrochemical industry.
Download or read book Ecology and the Environment written by Russell K. Monson and published by Springer. This book was released on 2014-10-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, plant biology is considered from the perspective of plants and their surrounding environment, including both biotic and abiotic interactions. The intended audience is undergraduate students in the middle or final phases of their programs of study. Topics are developed to provide a rudimentary understanding of how plant-environment interactions span multiple spatiotemporal scales, and how this rudimentary knowledge can be applied to understand the causes of ecosystem vulnerabilities in the face of global climate change and expansion of natural resource use by human societies. In all chapters connections are made from smaller to larger scales of ecological organization, providing a foundation for understanding plant ecology. Where relevant, environmental threats to ecological systems are identified and future research needs are discussed. As future generations take on the responsibility for managing ecosystem goods and services, one of the most effective resources that can be passed on is accumulated knowledge of how organisms, populations, species, communities and ecosystems function and interact across scales of organization. This book is intended to provide some of that knowledge, and hopefully provide those generations with the ability to avoid some of the catastrophic environmental mistakes that prior generations have made.

This book was released on 2012-12-06 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapidly growing human population has increased the dependence on fossil fuel based agrochemicals such as fertilizers and pesticides to produce the required agricultural and forestry products. This has exerted a great pressure on the non renewable fossil fuel resources, which cannot last indefinitely. Besides, indiscriminate use ofpesticides for pests (weeds, insects, nematodes, pathogens) control has resulted in serious ecological and environmental problems viz. , (A) Increasing incidence of resistance in pest organisms to important pesticides. (B) Shift in pests population, particulary in weeds and insects. In weeds, species that are more closely related to the crops they infest have developed. In insects, scenario is most grim, the predators have been killed and minor insect pests have become major pests and require very heavy doses ofhighly toxic insecticides for their control. (C) Greater environmental pollution and health hazards (a) particularly from contamination of surface and underground drinking water resources and (b) from their inhalation during handling and application. (D) Toxic residues of pesticides pollute the environment and may prove hazardous to even our future generations. (E) Some agricultural commodities may contain minute quantities ofpesticides residues, with long tenn adverse effects on human and livestock health. Therefore, serious ecological questions about the reliance on pesticides for pests control has been raised. The use of fertilizers, besides causing environmental problems has also impoverished the soil health and decreased the beneficial soil fauna. For example, in some major crop rotations viz.
