While botanically quite different, coffee, cocoa and tea are often considered together in the teaching of students of horticulture or agriculture. This is because all three represent plantation cash crops that are used as stimulant beverages and are grown in many of the warmer, less developed regions of the world. While there are a number of specialist books available on aspects of each individual crop, as well as grower manuals focusing on particular regions, there is currently no book that provides a general introductory overview of the scientific principles underlying production of all three crops. This book fills this gap, and will serve as a broad-based text for students of agriculture, horticulture and food science, as well as professionals seeking an overview of the topic.

In common with other titles in this series, this volume describes the scientific principles that are the bases of crop production practices. This volume focuses on the leafy salad vegetables: lettuce, endive and chicory. It opens with a review of world production data, crop uses, botany, taxonomy and evolution. It then describes the genetics and breeding of the crop, including cultivar development and germplasm resources. Physiological aspects, such as germination, growth and development, are then discussed. Production methods worldwide, including growing under cover in protected environments, are reviewed, before consideration of harvesting and seeds, pests and diseases, and economics and marketing. The book is written by one of the world 's leading authorities on the subject and will be indispensable for advanced students and growers in horticulture.

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.

Changing Climate and Resource Use Efficiency in Plants reviews the efficiencies for resource use by crop plants under different climatic conditions. This book focuses on the challenges and potential remediation methods for a variety of resource factors. Chapters deal with the effects of different climatic conditions on agriculture, radiation use efficiency under various climatic conditions, the efficiency of water and its impact on harvest production under restricted soil moisture conditions, nitrogen and phosphorus use efficiency, nitrogen use efficiency in different environmental conditions under the influence of climate change, and various aspects of improving phosphorus use efficiency. The book provides guidance for researchers engaged in plant science studies, particularly Plant/Crop Physiology, Agronomy, Plant Breeding and Molecular Breeding. In addition, it provides valuable insights for policymakers, administrators, plant-based companies and agribusiness companies.

Part of a series which presents papers of topical interest relating to the breeding of plants important to agriculture and horticulture.

The understanding and management of land resources used by grazing animals are of major importance to ecologists and agricultural and environmental scientists. This book fills a major gap in the market by synthesising a range of perspectives on grazing systems, drawn from plant science, animal science and ecology. It outlines the principles of herbage growth and competition, of animal nutrition and grazing behaviour, and of the interactions of plant and animal factors that are central to an understanding of grazing systems. Chapters on the management of grazing systems cover both intensive and extensive systems (including rangelands) from all major agroecological zones of the world. The book is written by leading authorities from the USA, UK, Australia, New Zealand, South Africa, Israel and France. It represents a major contribution to the literature for advanced students and research workers concerned with plant science (especially grasslands), animal science (especially ruminants), and natural and agricultural ecosystems.

Plant Breeding Reviews is an ongoing series presenting state-of-the art review articles on research in plant genetics, especially the breeding of commercially important crops. Articles perform the valuable function of collecting, comparing, and contrasting the primary journal literature in order to form an overview of the topic. This detailed analysis bridges the gap between the specialized researcher and the broader community of plant scientists.

Improvements in adaptation and maturity leading to greater yield are the most important criteria for the acceptance of a new crop cultivar, since it is the yield which dictates the economic value of the crop. Therefore, yield improvement is one goal of virtually every crop breeding program. Many such programs have tended to concentrate on identifying the genetic traits responsible for higher yield and selecting each of them in the later stages of the breeding cycle. However, selection for yield per se is still the most effective method, since it is a combination of traits, operating within the limits of the system, which finally determines yield. This book presents a whole-system, or holistic viewpoint for the improvement of adaptation, maturity and yield. Central to its thesis is recognition that system-established changes in levels of the components of the plant system, within a constant capacity, i.e. within the limitations of the system, determines yield and other cultivar characteristics. It goes on to describe how this can improve our understanding of plant systems and enable breeders to maximize performance under prevailing field conditions. Based principally on 25 years of research by the authors, the ideas presented in this book are essential reading for crop physiologists and plant breeders.

Lupins have until recently remained wild or semi-domesticated species of minor interest to agriculture, although their value as a rotation crop was noted 2,000 years ago. However, with the advent of the science of genetics in the early twentieth century, full domestication of Lupinus species for use as crops was begun, by the combination of favourable genes such as those for low alkaloid content, non-shattering pods and soft seeds. As a result several lupin species have become an important part of temperate farming systems as a high protein crop for both animal and human consumption. This book gives an authoritative account of the history, distribution and taxonomy of Lupinus species and the current knowledge of all aspects of their agronomy and impact on agriculture, including breeding, genetics and biotechnology, nutrition, nitrogen fixation, transport physiology, toxins, stress responses, pests and diseases, agronomy and farming systems, composition and food uses, economic value and trade. Contributions are made by researchers in Australia and Europe who have had key roles in lupin research. The book is essential reading for botanists, agronomists, plant breeders and geneticists involved with lupins and other grain legumes or with an interest in crop domestication and evolution. It also provides important information for lecturers and students of agriculture and for professionals in the livestock and food industries.

The development of computer simulation models is an important growth area in both pure and applied ecology. The opportunity that mathematical models provide to integrate the components of an ecosystem, results in the ability to make quantitative predictions about the future behaviour of that system, or of elements within it. This means that they are powerful tools with wide applications and enormous potential for increasing our understanding of natural systems and our ability to use them in a sustainable way. This book is, almost uniquely, a complete account of one such model, the Hurley Pasture Model, a dynamic, deterministic, mechanistic simulation model for grassland, which has been developed by the author over some twenty years, in collaboration with scientists at several centres. Firstly, the rationale and theoretical elements of this type of model are described. An overview of the Hurley grassland simulator and the derivation and construction of its plant, animal, soil and litter, water, and environment and management components is then given. Next, the model is evaluated by a series of long and short-term dynamic simulations and steady state responses, which demonstrate how predictions can be made about the effects of, for example, climate change or particular regimes of fertilizer application, grazing or cutting. This book will be of great value to grassland agronomists and modellers, crop physiologists and plant ecologists, and to students of ecology as a case study of a plant ecosystem model. It will also be of interest to other ecologists and environmentalists and those in the field of computer modelling and its applications.

The two closely related species of Potato Cyst-Nematodes (PCN), Globodera rostochiensis (Woll) and Globodera pallida Stone have a worldwide distribution. Both are internationally recognized plant quarantine organisms of actual or potential major economic importance wherever potatoes are grown or traded. They occur in large soil masses and also adhere to potato tubers as microscopic cysts, which represent a complex of morphologically identical, but behaviourally different virulence groups, or pathotypes. This presents major problems for their detection, identification and management. This book is a synthesis of current practical knowledge and underpinning scientific research on PCN globally. It is arranged in five sections, comprising nineteen chapters by leading practitioners and research nematologists, in which the biology, detection, identification and control options (including plant resistance) for PCN are examined. In addition, its worldwide status is considered, including South America, where PCN co-evolved with its potato host. Essential information is provided for professionals and advanced students of plant nematology and crop protection.

The major temperate forage legumes are of global importance in the sustainable productivity of ruminant feed in the developed world. This book brings together in one volume all aspects of their basic biology and associated production practices. Emphasis is placed on the importance of understanding plant characteristics and their consequences in terms of forage output, quality and utilization by livestock. Recent research advances are reviewed and put into context and several recently commercialised species are also covered. The introduction considers the history, current extent, benefits and limits of temperate forage legume usage. Subsequent chapters are dedicated to a comprehensive examination of each forage species in turn, dealing with their origin, morphology, physiology, ecology, nitrogen-fixing capability, cultivars, seed production, nutritive value and productivity. The key factors for optimal management are identified and the prospects for the future outlined, including the potential arising from the use of biotechnology. This book is essential reading for degree and postgraduate students of plant science, agronomy and animal production. Additionally, students and researchers in ecology and environmental science will also find it a valuable resource. The management sections will be of particular value to grassland advisers, consultants and progressive land users.

The grasses and legumes grown in pastures and rangelands form the basis of the worldwide animal production industry. Some species also have a significant role in the sport and leisure industry, for playing surfaces such as golf courses and football fields. It is therefore vitally important to ensure that seed supplies of appropriate species are available for use on a commercial scale. This book is published in association with the International Herbage Seed Production Research Group. It brings together leading researchers and along with its companion volume Forage Seed Production Volume 2: Tropical and Subtropical Species (to be published in late 1998), provides the definitive resource for all those concerned with breeding and profitable seed production for grasses and legumes used within grazing systems or recreation and amenity provision. The book is in two parts. Part 1 covers all aspects relevant to seed production, including improving seed yield and quality, crop management, harvesting, processing and the international seed trade. Part 2 consists of eleven case studies from eight countries covering three continents. This book and its companion should be read by all seed scientists involved in the breeding and commercial production of grass and legume seed. They also represent a valuable asset for all commercial seed suppliers. Additionally, the information presented within the book is important for all students and lecturers within departments of agriculture and plant breeding.

The practice of growing two or more crops together is widespread throughout the tropics and is becoming increasingly practised in temperate agriculture. The benefits of nutrient exchange, reduced weed competition and pathogen control can generate substantial improvements in growth and yield. In this book John Vandermeer, a leading worker on the subject, shows how classical ecological principles, especially those relating to competition and population ecology, can be applied to intercropping. Despite the large amount of research activity directed towards the subject over the last 20 years, the practice of intercropping has, until now, received very little serious academic attention. The Ecology of Intercropping is unique in approaching the question of intercropping from a theoretical point of view. In addition the details of the approach will take as their starting point well-accepted ecological theory. Using this basis the author shows how the approach can be used to design and evaluate intercropping systems to improve agricultural yields.

PGPR Amelioration in Sustainable Agriculture: Food Security and Environmental Management explores the growth-promoting rhizobacteria (PGPR) that are indigenous to soil and plant rhizosphere. These microorganisms have significant potential as important tools for sustainable agriculture. PGPR enhance the growth of root systems and often control certain plant pathogens. As PGPR amelioration is a fascinating subject, is multidisciplinary in nature, and concerns scientists involved in plant heath and plant protection, this book is an ideal resource that emphasizes the current trends of, and probable future of, PGPR developments. Chapters incorporate both theoretical and practical aspects and may serve as baseline information for future research. This book will be useful to students, teachers and researchers, both in universities and research institutes, especially working in areas of agricultural microbiology, plant pathology and agronomy.

Soilborne diseases have, until recently, received less attention than plant diseases affecting the shoot and foliage. However, this is not a reflection of their economic importance, but rather of difficulties in investigating and detecting pathogens below soil level. Many soilborne diseases are stress related and it is in the tropics where crop growth is particularly limited by environmental stress, predisposing crops to infection by soilborne pathogens. There is thus a great need for information on soilborne diseases of crops in the tropics. This book aims to fill this need by providing reviews of relevant research. It covers the major tropical crops and also includes general chapters on principles, ecology and control. Written by leading research workers from countries including the UK, USA, Australia and India, it will be indispensable for plant pathologists working in this area.

Phosphorus is an essential element for plant growth and its input has long been recognized as necessary to maintain profitable crop production. However, phosphorus inputs can also increase the biological activity of surface waters and this can lead to the destruction of such aquatic ecosystems. Advanced eutrophication of surface water leads to problems with its use for fisheries, recreation, industry and drinking, due to the increased growth of undesirable algae and aquatic weeds, and oxygen shortages caused by their death and decomposition. It is therefore important to have a good understanding of the causes and mode of phosphorus loss from soil to water, to enable the problems to be controlled and managed. This book has been developed from an international workshop held in Ireland in late 1995. It is the first comprehensive consideration of the topic, and many leading researchers in the area have contributed to it. It is essential reading for all soil scientists and freshwater biologists, as well as for environmentalists, ecologists and agriculturalists concerned with sustainable land management and pollution. The book is also recommended to fisheries managers, fertilizer manufacturers and biologists working for water utilities.

Genetics has transformed plant pathology on two occasions: first when Mendelian genetics enabled the discovery that disease resistance was a heritable trait in plants, and secondly when Flor proposed the "gene-for-gene" hypothesis to explain his observations of plant-parasite interactions, based on his work on flax rust in North Dakota starting in the 1930s. Our knowledge of the genetics of disease resistance and host-pathogen coevolution is now entering a new phase as a result of the cloning of the first resistance genes. This book provides a broad review of recent developments in this important and expanding subject. Both agricultural and natural host-pathogen situations are addressed. While most of the book focuses on plant pathology, in the usual sense of the term embracing fungal, bacterial and viral pathogens, there is also consideration of parasitic plants and a chapter demonstrating lessons to be learnt from the mammalian immune system. Three overall themes are addressed: genetic analyses and utilization of resistance; population genetics; and cell biology and molecular genetics. Chapters are based on papers presented at the British Society for Plant Pathology Presidential meeting held in December 1995, but all have been revised and updated to mid-1996. Written by leading authorities from North America, Europe and Australia, the book represents an essential update for workers in plant genetics, breeding, biotechnology and pathology.

Maintaining soil health is fundamental to successful crop production and ecosystem sustainability. To enable effective management soil health must first be measured and then monitored and so the authors review and evaluate how soil organisms can be used to fulfil this role. This book is essential for all soil scientists and consultants. It is of particular relevance to those involved in soil health monitoring and maintenance as well as those undertaking soil remediation. It is also important reading for agronomists, ecologists and environmentalists. This book is a comprehensive and effective resource for all those working to sustain healthy soils.

Plants producing an aromatic oil, fruit, or seed have been used in religious ceremonies, for personal use and adornment, and for flavoring throughout history. There is now also world-wide pressure by consumers to use perceived natural compounds in edible and personal products. It is vital that producers should be able to service this growing demand efficiently, economically and above all reliably. Many essential oil crops are part of the economy of countries with expanding populations, resulting in increasing pressure on land to produce food and fuel. It is thus important to ensure the optimum social and economic benefit from establishing and growing essential oil crops. This book is concerned with growing essential oil plants profitably to obtain an aromatic derivative. Each chapter covers a different family. A brief history of the use and economic development is given, and cultivation, harvesting and distilling described. Results of current research and recommendations for improved agronomic practices, together with methods of adding value to the crop, such as producing honey or processing the oil, are also discussed.

Biological management of nutrient supply to plants is intrinsically more complex than the provision of nutrients as inorganic fertilizers. We need to know whether the nutrients released are retained or lost from the system, whether rates of decomposition can be manipulated to improve nutrient use efficiency, and how the various fractions of plant residues translate into pools of organic matter in soil. Only then can predictive models for nutrient release, plant uptake and soil organic matter dynamics be truly tested and validated. This book brings together contemporary ideas on the characterization and manipulation of plant quality and especially its role in soil organic matter formation and nutrient cycling. It contains work from the leading workers in both temperate and tropical systems. There are also contributions describing work outside decomposition in soil ecosystems, such as the work of plant biochemists and animal nutritionists, as research in these areas has provided many ideas and concepts used in plant quality analysis. A wide range of topics is covered from investigations at the molecular level through to management options for farmers in relation to optimising biological management of crop residues. The work presented in this volume is valuable to all those researching and managing the supply of nutrients to plants. It is important reading for soil scientists, plant physiologists and crop scientists.
