This book was released on 2020 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifying suitable species for simple and complex seeding mixtures in specific growing conditions can reduce negative impact of invasive species and anthropogenic disturbance. Field and greenhouse studies were conducted to (a) evaluate the establishment of cool-season perennial grass and legume genotypes; (b) determine interaction effects of grass-legume mixtures with planting time and conditions; and (c) assess competitive ability of cool-season perennial grasses against invasive species. Field study showed spring planting is best to establish vegetation in Wyoming conditions in both improved- and resource-poor sites. Non-native grass, particularly, tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.] genotypes, contributed to higher herbage production. Cicer milkvetch (Astragalus cicer L.) performed best among legumes. Mixture of legumes with grasses had an overyielding effect. Incorporation of at least 25% of legumes in the mixture produced above average forage quality with crude protein >150 g kg−1. The greenhouse study assessed the competitive ability of basin wildrye (Leymus cinereus (Scribn. & Merr.) Á. Löve), tall fescue, and crested wheatgrass [Agropyron cristatum (L.) Gaertn.] against downy brome (Bromus tectorum L.) in three different soil sources with varying soil nutrient conditions. The results showed soil sources affected competitive ability of perennial grasses as well as invasive species (downy brome). Competitive response of perennial grasses was lower against downy brome in high soil nutrient conditions. Non-native perennial grasses had higher competitive ability against downy brome in low soil nutrient conditions. Overall, the study demonstrated tall fescue and cicer milkvetch have the potential for use in both improved and resource-poor conditions.

Download or read book Fodder Crops and Amenity Grasses written by Beat Boller and published by Springer Science & Business Media. This book was released on 2010-01-14 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grassland farming in Europe was already established during the settlement of the rst farmers together with their domesticated animals after the last ice age. Since then, grassland provides the forage basis to feed ruminant animals for the p- duction of meat and milk. Depending on the ecological conditions and intensity of usage, various plant communities with different species developed, displaying a rich biodiversity. With the introduction of improved crop rotations at the end of the 16th century, grasses and legumes were also grown to an important extent as forage crops on arable land. In the last decades the importance of amenity grasses increased markedly, due to the demand of the society for new usages like landscape protection. Around 1900 interested farmers and academics identi ed the need for gra- land improvement through systematic selection and seed production. This marks the beginning of breeding and research in companies but also at universities and specialized research institutes. Plant collection started with many of the species that are still of importance today. The collected materials were grouped according to the intended use and some type of phenotypic selection was applied. Seed mul- plication of such populations was performed in pure stands and the harvested seed was marketed. Although the vegetative biomass and its quality are of utmost imp- tance in forage crop breeding, it is the seed yield potential which determines the commercial success of a new variety.

Download or read book Root Ecology written by Hans de Kroon and published by Springer Science & Business Media. This book was released on 2003-05-21 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

This book was released on 2001 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Opuntias are multipurpose plants that are increasingly being used in agricultural systems in arid and semi-arid areas. Due to its high water-use efficiency, it is particularly useful as forage in times of drought and in areas where few other crops can grow, and it is now considered a key component for the productivity and sustainability of these regions. This publication presents current scientific and practical information on the use of the cactus Opuntia as forage for livestock.
Download or read book Perennial Crops for Food Security written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-06-07 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication presents the latest research in perennial crop breeding and programmes, and provides direction on where the field of perennial crop is heading. Many production systems and agricultural practices are no longer sustainable today as their effects on soils, water, biodiversity, and livelihood are significant. Mainstreaming the use of perennial crops into current practices can contribute to stabilize fragile soils and maintain natural processes essential to obtain stable and high yields. To face the challenges and risks of the twenty-first century, increasing the perenniality of crops and agricultural systems should become a larger research, development and policy focus.

Download or read book Grass for Dairy Cattle written by Jerome Henry Cherney and published by Cabi. This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the current interest in the environmental and economic sustainability of dairy farming, grass forage crops have emerged as a potential solution to some of the nutrient management problems now encountered on intensively managed dairy farms. The expansion and reintegration of grass-based systems into the mainstream of dairying systems will require a major paradigm shift involving economic, social and ecological, as well as biological factors. This book examines the role of grass in milk production in sustainable agricultural ecosystems. It provides a current summary of the role of grass in dairy cattle systems, including the breeding, management, storage, feeding and economics of grass for both lactating and dry dairy cows. Written by leading specialists from Australia, Europe, New Zealand, North and South America, this is an essential reference source for researchers, dairy industry professionals and advanced students of forage and dairy cattle nutrition.

This book was released on 2013-04-17 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forage plant breeding has entered the genome era. This timely book reviews the latest advances in the development and application of molecular technologies which supplement conventional breeding efforts for our major forage crops. It describes the plethora of new technologies and tools now available for high-throughput gene discovery, genome-wide gene expression analysis, production of transgenic plants, genome analysis and marker-assisted selection as applied to forage plants. Detailed accounts are presented of current and future opportunities for innovative applications of these molecular tools and technologies in the identification, functional characterisation, and use of valuable genes in forage production systems and beyond. This book represents a valuable resource for plant breeders, geneticists, and molecular biologists, and will be of particular relevance to advanced undergraduates, postgraduates, and researchers with an interest in forage legumes and grasses.
