This book was released on 2019 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual ryegrass (Lolium multiflorum Lam.) can be divided into two cytotypes: diploid (2n = 2x = 14) or tetraploid (2n = 4x = 28). Transforming annual ryegrass from diploid to tetraploid often results in increased seedling vigor, more robust growth and, thus, supposedly greater yield. There has been conflicting research that suggests no difference in yield between diploid and tetraploid cultivars, but livestock producers’ question whether benefits exist to utilizing tetraploid cultivars for grazing cattle. This study sought to determine if annual ryegrass cytotype affected cattle average daily gain. Although there were no differences in average daily gain between cytotypes, there were differences among cultivars. In 2017, Jumbo (4x) produced the greatest weight gain, while in 2018, Tam-90 (2x) generated the greatest gain. This study suggests that there are no advantages attributed to average daily gain by utilizing tetraploid, as opposed to diploid cultivars.

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 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.

Available in PDF, EPUB and Kindle. Book excerpt: Perennial Grasses for Bioenergy and Bioproducts: Production, Uses, Sustainability and Markets for Giant Reed, Miscanthus, Switchgrass, Reed Canary Grass and Bamboo brings together a team of international authors to explore the current utilization, sustainability and future perspectives of perennial grasses in the bioeconomy. The book begins by examining the role of these crops as feedstock for bioenergy, in particular advanced biofuels and bioproducts. It then offers five chapters, each covering one perennial grass type, namely giant reed, miscanthus, switchgrass, reed canary grass and bamboo. The book covers their breeding, cultivation, harvesting, pre-treatment, economics and characterization. The book goes on to present the thermochemical conversion pathways for different types of feedstock. The last chapter explores issues concerning sustainability of perennial grasses, including their production in marginal lands. This thorough overview is a helpful reference for engineering researchers and professionals in the bioenergy sector, whose understanding of feedstock characterization, sustainability and production is critical in the development of conversion technologies. Those in the industrial crops sector will benefit from discussion of various issues surrounding crop production, which can guide their feedstock cultivation, harvesting and pre-treatment for specific conversion processes or end use. The book is also a useful resource for instructors and students in Masters and PhD programs in the area of biomass and energy crops. Policy makers and government agents involved in regulating the bioenergy and bioproducts sector will find comprehensive information to guide their decision making. - Explores the whole value chain of grassy feedstock for advanced biofuels and bioproducts, from cultivation to end use, including biomass characterization (physical properties, chemical composition, etc.) and conversion and sustainability - Examines the sustainability and economic factors related to perennial grasses and their conversion into biofuels and bioproducts - Includes a complete list of grasses relevant for energy uses, and tables with their current and expected future uses and markets

Download or read book Breeding Fodder Crops for Marginal Conditions written by O.A. Rognli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains papers and posters presented at the 18th Eucarpia Fodder Crops Section Meeting held at Loen, Nordfjord, Norway in August 1993. In most environments some form of marginal conditions or stress prevails. Few crops are being produced under such a wide range of environmental and management stresses as fodder crops. Improved adaptation of fodder crops to marginal conditions is crucial in developing sustainable, low-input agricultural systems. The book is unique in demonstrating the large diversity both in crops and environmental stresses that confront the forage breeders. Both general and specific aspects of adaptation to marginal growing conditions are presented, ranging from problems caused by snow and ice in the Subarctic regions of Europe to the severe drought problems in the Mediterranean regions. For everyone involved in studies of adaptation and breeding of perennial plants for marginal conditions or stress environments.
