The cacao ("Theobroma cacao") plant is an important Neo-Tropical species whose natural habitat is the Amazon basin. Over the last 30 years, there has been a considerable geographical expansion in the availability of cacao genetic resources. As a result the plant has a rich genetic diversity that exists at two levels: that of the primitive populations in the area of original distribution of the species, and that of the derived cultivated populations. This book provides a comprehensive review of our current knowledge of the diversity of the species. It starts by examining the diversity and inheritance of the characteristics of primitive populations in the Amazonian and Caribbean regions. It then looks at the evolution of diversity within cultivated populations first in South America and around the Caribbean, and then beyond the Americas. The book describes the inter-relationships between populations based on morphological and molecular markers. It also examines the conservation of genetic resources and how these genetic resources can be utilized to produce new cultivars.

In recent decades, the governance of the environment in agri-food systems has emerged as a crucial challenge. A multiplicity of actors have been enrolled in this process, with the private sector and civil society progressively becoming key components in a global context often described as neoliberalization. Agri-environmental governance (AEG) thus gathers a highly complex assemblage of actors and instruments, with multiple interrelations. This book addresses this complexity, challenging traditional modes of research and explanation in social science and agri-food studies. To do so, it draws on multiple theoretical and methodological insights, applied to case studies from Asia, Europe, Africa, and the Americas. It elaborates an emergent approach to AEG practices as assemblages, looking at the coming-together of multiple actors with diverse trajectories and objectives. The book lays the foundations for an encompassing theoretical framework that transcends pre-existing categories, as well as promoting innovative methodologies, which integrate the role of social actors - including scientists - in the construction of new assemblages. The chapters define, first, the multiplicities and agencies inherent to AEG assemblages. A second set tackles the question of the politics in AEG assemblages, where political hierarchies interweave with economic power and the search for more democratic and participative approaches. Finally, these insights are developed in the form of assemblage practice and methodology. The book challenges social scientists to confront the shortcomings of existing approaches and consider alternative answers to questions about environmental governance of agri-food systems.

This book, Plant Breeding, has it bases in an earlier text entitled An Introduction to Plant Breeding by Jack Brown and Peter Caligari, first published in 2008. The challenges facing today s plant breeders have never been more overwhelming, yet the prospects to contribute significantly to global food security and farmers quality of life have never been more exciting and fulfilling. Despite this there has been a worrying decline in public funding for plant breeding-related research and support for international centers of germplasm development and crop improvement. In part, this has resulted in a serious reduction in the number of young people interested in devoting their professional careers to plant breeding as well as the number of universities offering plant breeding courses or conducting relevant research in plant breeding. The authors aim in writing this book is to provide an integrated and updated view of the current scientific progress related to diverse plant breeding disciplines, within the context of applied breeding programs. This excellent new book will encourage a new generation of students to pursue careers related to plant breeding and will assist a wider audience of agricultural students, agronomists, policy makers and those with an interest in agriculture in gaining insight about the issues affecting plant breeding and its key role in improving the quality of life of people and in securing sufficient food, at the quality required and at an affordable price. With comprehensive coverage including questions designed for students, and an accompanying website containing additional material to help in the study of the subject, Plant Breeding is an ideal text for all those studying plant and crop sciences, and a convenient reference source for professionals working in the area. All libraries within universities and research establishments where biological and agricultural sciences are studied and taught should have multiple copies of this book.

Since the second half of the 20th Century, our agricultural bee pollinators have faced mounting threats from ecological disturbance and pan-global movement of pathogens and parasites. At the same time, the area of pollinator-dependent crops is increasing globally with no end in sight. Never before has so much been asked of our finite pool of bee pollinators. This book not only explores the evolutionary and ecologic bases of these dynamics, it translates this knowledge into practical research-based guidance for using bees to pollinate crops. It emphasizes conserving wild bee populations as well as culturing honey bees, bumble bees, and managed solitary bees. To cover such a range of biology, theory, and practice from the perspectives of both the pollinator and the crop, the book is divided into two volumes. Volume 1 focuses on bees, their biology, coevolution with plants, foraging ecology and management, and gives practical ways to increase bee abundance and pollinating performance on the farm. Volume 2 (also available from CABI) focuses on crops, with chapters addressing crop-specific requirements and bee pollination management recommendations. Both volumes will be essential reading for farmers, horticulturists and gardeners, researchers and professionals working in insect ecology and conservation, and students of entomology and crop protection.

Plants are frequently exposed to unfavorable and adverse environmental conditions known as abiotic stressors. These factors can include salinity, drought, heat, cold, flooding, heavy metals, and UV radiation which pose serious threats to the sustainability of crop yields. Since abiotic stresses are major constraints for crop production, finding the approaches to enhance stress tolerance is crucial to increase crop production and increase food security. This book discusses approaches to enhance abiotic stress tolerance in crop plants on a global scale. Plants scientists and breeders will learn how to further mitigate plant responses and develop new crop varieties for the changing climate.

Global climate change affects crop production through altered weather patterns and increased environmental stresses. Such stresses include soil salinity, drought, flooding, metal/metalloid toxicity, pollution, and extreme temperatures. The variability of these environmental conditions pared with the sessile lifestyle of plants contribute to high exposure to these stress factors. Increasing tolerance of crop plants to abiotic stresses is needed to fulfill increased food needs of the population. This book focuses on methods of improving plants tolerance to abiotic stresses. It provides information on how protective agents, including exogenous phytoprotectants, can mitigate abiotic stressors affecting plants. The application of various phytoprotectants has become one of the most effective approaches in enhancing the tolerance of plants to these stresses. Phytoprotectants are discussed in detail including information on osmoprotectants, antioxidants, phytohormones, nitric oxide, polyamines, amino acids, and nutrient elements of plants. Providing a valuable resource of information on phytoprotectants, this book is useful in diverse areas of life sciences including agronomy, plant physiology, cell biology, environmental sciences, and biotechnology.

The book also shows in great detail that the history of science, technology, and colonialism can shed light on contemporary problems in natural resource management and global policy making.

A biodynamic farm is an integrated, holistic organism which balances animal husbandry with growing a range of plants, crops and trees. Balance is of the utmost importance, and will result in a sustainable farm. This book focuses in depth on one aspect of biodynamic farming: growing crops. It addresses all aspects of crop husbandry, from the nature of plants and issues of land use to cultivating grassland, weed control, crop rotation, seeds and sowing, and growing cereals, row crops, legumes, fodder crops and herbs. This is a comprehensive overview of crops and cropping for biodynamic farmers, written by experts in their field.

The first edition of this higly regarded text was published in 1979 to provide a general introduction to the principles of plant breeding. It has been out of print since late 1993 and a new edition is long overdue as there are no up to date and comprehensive single volumes on the subject in print.

The original text has been amended and enhanced where there have been advances in plant breeding to provide coverage of recent developments relevant to crop improvement, such as intellectual property rights, biotechnology and the use and conservation of genetic resources. The emphasis of the text will be, as it was for the first edition, on the principles of plant breeding and the expanded range of techniques now available for effective crop improvement.

As soil and crop management procedures have become more complex, County Agricultural Agents, farm advisors, consultants, and fertilizer and chemical dealers have had to specialize in some aspect of soil fertility and crop nutrition management procedures, limiting their ability to provide a range of advice and services. Most farmers and growers can no longer turn to just one source for the information and instruction needed to achieve their production goals.

With over 70 percent new material, the second edition of the Plant Nutrition and Soil Fertility Manual discusses the principles determining how plants grow and the elements essential for successful crop production, with a focus on the principles of soil fertility and plant nutrition. The book covers physical and chemical properties of soil, chemical and organic fertilizers, soil acidity and alkalinity, liming and liming materials, and micronutrients essential to plant growth. It also describes elements toxic to plants, soil testing, and plant analysis.

The topics and discussion in this self-contained book are practical and user-friendly, yet comprehensive enough to cover material presented in upper-level soil and plant science courses. It allows practitioners with general background knowledge to feel confident applying the principles presented to soil/crop production systems.

Have you ever wondered why we eat wheat, rice, potatoes and cassava? Why we routinely domesticate foodstuffs with the power to kill us, or why we chose almonds over acorns? Answering all these questions and more in a readable and friendly style, this book takes you on a journey through our history with crop plants. Arranged into recurrent themes in plant domestication, this book documents the history and biology of over 50 crops, including cereals, spices, legumes, fruits and cash crops such as chocolate, tobacco and rubber. In The Nature of Crops John Warren reveals: -Why the Egyptians worshipped onions; -Why red-flowering runner beans provide fewer beans than white-flowering; -The inherent dangers of being a pineapple worker; and -Why a bird will always beat you in a chilli pepper eating competition!

As the world's population increases the need to produce greater quantities of major staple crops such as wheat, rice, maize, potato, cassava, soybean, sweet potato, barley, and banana in order to sufficiently feed the people of the world continues to grow. "Breeding Major Food Staples "covers improving yields and quality of these crops through breeding and the use of molecular biology tools such as gene transfer, genome mapping, biofortification, and bioinformatics. This book will be an important reference for anyone working in crop breeding.

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.
