Vegetable Production and Practices

by Gregory E Welbaum

Successful vegetable production in a modern competitive market requires an understanding of many more factors than the biology of crops and the production techniques involved. This major new textbook brings the science and practice of vegetable production right up to date by addressing modern culture techniques and the recent challenges of consumer demand facing producers today. It introduces vegetable production from the perspective of producing high quality produce that satisfies the needs of the modern consumer. Beginning with the basics of how vegetables are grown using high and low input methods, including organic and sustainable production techniques, the book goes on to introduce and discuss many topics covered less comprehensively in older texts, including Good Agricultural Practices to improve quality, reduce biological contamination and secure food safety; water management; cropping systems; plasticulture; protected culture and mineral nutrition. Vegetable Production and Practices also introduces the use of molecular biology for genetic improvement of crops. Issues specific to individual vegetable crops are addressed by family, including their diseases, harvesting, quality attributes and other issues of increasing importance to consumers, including the role of vegetables in human health. Professor Gregory E. Welbaum has a long history of teaching successful courses in horticulture at Virginia Tech and other universities in the US and worldwide. Vegetable Production Practices has been specifically designed to accompany courses in vegetable crop production, so is ideally suited to inspire students in crop and horticultural sciences, as well as provide a useful reference for experienced practitioners.

Vegetable Seeds: Production and Technology

by Gregory E Welbaum

Most food and fiber crops are produced from seed. This means that the world's population is dependent on annual seed production for its food supply. Vegetable seed production is much different and more challenging than production of grain crops. This book explains the biology and technology behind producing, maintaining, and enhancing the quality of vegetable seeds from breeding through to the marketed product. It begins with six chapters on a broad range of seed-related topics: the importance of seeds, reproductive biology of plants, genetic improvement strategies, quality assurance of seed production, post-harvest seed enhancement, and organic production. The remaining chapters cover seed production in eleven important vegetable families. Each chapter provides a description of the botany, types and cultivars, genetic improvement, pollination, soil fertility management, pest management, crop production, harvesting, post-harvest handling, and seed yields. The aim of this book is to educate how to produce high-quality vegetable seeds. Incorporating both current methodologies and recent research results, it is suitable for students, researchers, and professionals in the seed industry.

The Vegetarian Imperative

by Anand M. Saxena

We have learned not to take food seriously: we eat as much as we want of what we want when we want it, and we seldom think about the health and environmental consequences of our choices. But the fact is that every choice we make has an impact on our health and on the environment. In The Vegetarian Imperative, Anand M. Saxena, a scientist and a vegetarian for most of his life, explains why we need to make better choices: for better health, to eliminate world hunger, and, ultimately, to save the planet. Our insatiable appetite for animal-based foods contributes directly to high rates of chronic diseases—resulting in both illness and death. It also leads to a devastating overuse of natural resources that dangerously depletes the food available for human consumption. The burgeoning population and increasing preference for meat in all parts of the world are stretching planetary resources beyond their limits, and the huge livestock industry is degrading the agricultural land and polluting air and water.Continuing at this pace will bring us to the crisis point in just a few decades—a reality that threatens not only our current lifestyle but our very survival. This book shows us a way out of this dangerous and vicious cycle, recommending a much-needed shift to a diet of properly chosen plant-based foods.Any one of these arguments alone—personal health, worldwide hunger, and environmental degradation—provides reason enough to stop consuming so much animal-based food; taken together, they make an unassailable case for vegetarianism. The Vegetarian Imperative will make you rethink what you eat—and help you save the planet.

Vegetation and Climate

by Siegmar-W. Breckle M. Daud Rafiqpoor

Vegetation, soil and climate are the most important components of ecological systems. The book represents a compact synthesis of our current knowledge about the ecology of the Earth and is thus the basis for understanding the major interrelationships in a global perspective. In the first part, with a rich endowment of illustrations and photographic material, the well-introduced book deals with the essential processes and operations on the Earth's surface that lead to the formation of the vegetation cover with its distinctive zonation. In the second part, the individual vegetation zones as large-scale ecosystems (i.e. zonobiomes of the biosphere) are consistently described comparatively according to certain criteria. In a short and compact form, the main characteristics and structures as well as examples of ecosystem processes are discussed. The large-scale ecosystems are at the same time the basis and reference system for all anthropogenic changes that have drastically altered the vegetation in the last millennia, but especially in the 20th century.This book is a translation of the original German 1st edition Vegetation und Klima by Siegmar-W. Breckle and M. Daud Rafiqpoor, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2019. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

Vegetation Dynamics

by Eamus, Derek and Huete, Alfredo and Yu, Qiang Derek Eamus Alfredo Huete Qiang Yu

Understanding ecosystem structure and function requires familiarity with the techniques, knowledge and concepts of the three disciplines of plant physiology, remote sensing and modelling. This is the first textbook to provide the fundamentals of these three domains in a single volume. It then applies cross-disciplinary insights to multiple case studies in vegetation and landscape science. A key feature of these case studies is an examination of relationships among climate, vegetation structure and vegetation function, to address fundamental research questions. This book is for advanced students and researchers who need to understand and apply knowledge from the disciplines of plant physiology, remote sensing and modelling. It allows readers to integrate and synthesise knowledge to produce a holistic understanding of the structure, function and behaviour of forests, woodlands and grasslands.

Vegetation Ecology of Socotra

by Bruno Mies Gary Brown

Although the unique flora of the Socotra Archipelago with its high degree of endemism has received much attention recently, little information is available on the vegetation and related ecological aspects. Based on their extensive field experience of the region, the authors have assimilated a vast amount of knowledge to produce this book, which gives a detailed insight into the plant ecology of Socotra, designated as a World Heritage Site by UNESCO in 2008. The book is divided into seven chapters. After a brief introduction and overviews of important abiotic features, various aspects of the vascular flora are presented in Chapter 4, together with accounts of the bryophyte and lichen flora. Ecology and adaptive strategies of the plants are dealt with in Chapter 5, and Chapter 6 gives a concise description of the main vegetation units. Finally, important management issues of the vegetation are discussed, an essential topic to ensure preservation of the natural heritage of the archipelago.

The Vegetation of Antarctica through Geological Time

Details of specific floras and ecosystems are provided within the context of changing geological, geographical and environmental conditions, alongside comparisons with contemporaneous and modern ecosystems. The authors demonstrate how palaeobotany contributes to our understanding of the palaeoenvironmental changes in the southern hemisphere during this period of Earth history. The book is a complete and up-to-date reference for researchers and students in Antarctic palaeobotany and terrestrial palaeoecology.

Vegetation of Central Asia and Environs

by Dilfuza Egamberdieva Münir Öztürk

Central Asia is a large and understudied region of varied geography, ranging from the high passes and mountains of Tian Shan, to the vast deserts of Kyzyl Kum, Taklamakan to the grassy treeles steppes.This region is faced with adverse conditions, as much of the land is too dry or rugged for farming. Additionally, the rich specific and intraspecific diversity of fruit trees and medicinal plants is threatened by overgrazing, oil and mineral extraction, and poaching. Countless species from the approximately 20 ecosystems and 6000 plant taxa are now rare and endangered.Traditional vegetation studies in this region are far from adequate to handle complex issues such as soil mass movement, soil sodicity and salinity, biodiversity conservation, and grazing management. However, data analysis using a Geographical Information System (GIS) tool provides new insights into the vegetation of this region and opens up new opportunities for long-term sustainable management. While vegetation planning can occur at a property scale, it is often necessary for certain factors, such as salinity, to be dealt with on a regional scale to ensure their effective management. GIS increases the effectiveness and accuracy of vegetation planning in a region. Such regional planning will also greatly increases biodiversity values.This book systematically explores these issues and discuses new applications and approaches for overcoming these issues, including the application of GIS techniques for sustainable management and planning. Professional researchers as well as students and teachers of agriculture and ecology will find this volume to be an integral resource for studying the vegetation of Central Asia.

The Vegetation of Georgia (South Caucasus)

by George Nakhutsrishvili

The book describes richness and diversity of Georgia's vegetation. Contrasting ecosystems coexist on the relatively small territory of the country and include semi-deserts in East Georgia, Colchic forests with almost sub-tropical climate in West Georgia and subnival plant communities in high mountains. West Georgia lacks xerophilous vegetation zone and mesophilous forest vegetation spreads from the sea level to subalpine zone. The Colchic refugium (West Georgia) ensured survival of the Tertiary's mesophilous forest flora. Vertical profile of the vegetation is more complex in East Georgia with semi-desert, steppe and arid open forest zone. In South Georgia the montane zone represented by montane steppe is devoid of forests

Vegetation of the Canary Islands (Plant and Vegetation #16)

by Marcelino J. del Arco Aguilar Octavio Rodríguez Delgado

The volcanic and oceanic nature of the Canary Islands, its rich plant biodiversity and high rate of endemism, as well as the relict character of some of its plant communities make it a territory of great biological interest. The main geographic, climatic, bioclimatic, biogeographic and floristic features of the Islands are shown and related to the distributional pattern of potential communities along an altitudinal gradient. Current vegetation units and their ecology are described and illustrated with numerous pictures. Potential vegetation units are summarized and comprehensive maps of the potential natural vegetation for each island are given. Human impact on the natural landscape, the occurrence of invasive plants, and the probable impact of climate change on the flora and vegetation are discussed. The conservation status of flora and vegetation are assessed. Four appendixes include a syntaxonomical scheme, a brief history of botanical studies and explorations in the Islands, ethnobotanical notes, and a list of selected literature.

The Vegetation of the Maltese Islands (Geobotany Studies)

by Salvatore Brullo Cristian Brullo Salvatore Cambria Gianpietro Giusso del Galdo

This book discusses the remarkable plant diversity of the Maltese Archipelago. Despite its relatively small area and long-term human exploitation, many different plant communities occur in this territory. The book presents phytosociological investigations, together with taxonomical studies, which have been conducted over more than forty years, highlighting the unique features of this central Mediterranean insular ecosystem. It also describes the phytosociological role played by several narrow endemic or phytogeographically relevant taxa and introduces many phytocoenoses exclusively growing in the archipelago. The study integrates the palaeogeographic issues linked to the ancient and intriguing history of the different civilizations that succeeded on the islands for thousands of years. The book also focuses on the N2000 habitats.

Vegetation Structure and Function at Multiple Spatial, Temporal and Conceptual Scales

by Elgene Owen Box

This commemorative volume of invited papers in vegetation science covers a full range of topics, objectives, methods and applications, including conservation and management tasks. These require study at different temporal and spatial scales, often simultaneously. Methodology is important in science, since it responds to particular questions and raises others. It is also closely related to the scale of investigation. Chapters in this book illustrate this interdependence, even in basic tasks such as vegetation sampling and description, measurements and mapping. Individual chapters present globally applicable systems, regional syntheses and local analyses and applications, plus conceptual methodologies, including currently debated hot topics. Vegetation types treated include tropical rainforests, temperate forests, dry steppes and scrub and local turf, sedge and moss communities. There are also chapters on re-vegetation, woodlot management, ecology of an invasive species, and trajectory planning in conservation. This book will be useful to both students and practitioners, for its reviews and examples and as a potential textbook suitable for graduate-level courses and seminars.

Vegetative Powers: The Roots of Life in Ancient, Medieval and Early Modern Natural Philosophy (International Archives of the History of Ideas Archives internationales d'histoire des idées #234)

by Fabrizio Baldassarri Andreas Blank

The volume analyzes the natural philosophical accounts and debates concerning the vegetative powers, namely nutrition, growth, and reproduction. While principally focusing on the early modern approaches to the lower functions of the soul, readers will discover the roots of these approaches back to the Ancient times, as the volume highlights the role of three strands that help shape the study of life in the Medieval and early modern natural philosophies. From late antiquity to the early modern period, the vegetative soul and its cognate concepts have played a substantial role in specifying life, living functions, and living bodies, sometimes blurring the line between living and non-living nature, and, at other moments, resulting in a strong restriction of life to a mechanical system of operations and powers. Unearthing the history of the vegetative soul as a shrub of interconnected concepts, the 24 contributions of the volume fill a crucial gap in scholarship, ultimately outlining the importance of vegetal processes of incessant proliferation, generation, and organic growth as the roots of life in natural philosophical interpretations.
