First published in 1997, this volume contributes to the knowledge for the trade of vegetables, fruits and tubers (so-called horticultural commodities). As African policy makers try to keep pace with new developments in private food trade, they require knowledge of the structures of private trade systems and the factors that govern their long-term development. The study analyses the structure and development of horticultural marketing channels in Kenya. It is based primarily on surveys of some 500 farmers in four districts and 750 horticultural traders in 18 market places. Commercial horticultural farmers, domestic traders, export traders, agents, facilitators, marketing cooperatives and processors are all reviewed. The study devotes special attention to the efficiency of collecting wholesalers, and to the development of rural assembly markets. It develops a model which can elucidate vertical differentiation processes in the Kenyan horticultural channels. The analyses show that marketing channel theory can be of great relevance to the developing world. The proposed vertical differentiation model can aid in predicting future changes in horticultural marketing systems, in Kenya as well as in other African countries.

The edible alliums are some of the most ancient cultivated crops and include onions, leeks, shallots, garlic and chives. They are grown in most regions of the world, from the subarctic to the humid tropics, although bulb onions are best adapted to production in subtropical and temperate areas. This book introduces the scientific principles that underlie production practices. It begins by discussing the classification, origins, distribution and economic importance of the major food alliums, before considering their structure, genetics and breeding. Chapters then follow on the physiology of crop growth, development and yield, on crop production and on flowering and seed production. Some alliums are harvested as bulbs and others as green shoots, and a chapter is devoted to the storage and dormancy of both types. Pests, diseases and weeds are then discussed, before a final chapter on the biochemistry and food science of alliums. The book is written at a level suitable for students of horticulture, crop science and food science, as well as for growers and crop consultants interested in the scientific principles that form the basis of their practice. It also provides a valuable example of how the different disciplines within plant sciences interrelate when applied to particular crops.

Perhaps the least appreciated dramatis personae in human history are plants. Humans, like all other animals, cannot produce their own food as plants do through photosynthesis, and must therefore acquire organic material for survival and growth by eating plants or by eating other animals that eat plants. Humans depend on plants not only as a food source, but also as building and clothing materials and as sources of medicines, psychoactive substances, spices, pigments, and more. With plants being such valuable resources, it is therefore not surprising that plants have been involved in practically all violent conflicts among different human societies. Ironically, plants have also been the source of materials to construct weapons or weapon parts. Wars have always constituted a large part of human history, and the overall theme of this book is that to understand the history of violent human conflict, we need to understand what specific materials plants make that people find so useful and worth fighting over, and what roles such plant products have played in specific conflicts. To do so, Plants and Human Conflict begins with a chapter explaining the basic biological facts of the interdependence between plants and humans, and the subsequent seven chapters describe the physical and chemical properties of specific plant products demonstrating how the human need for these products has led to wars as well as contributed to the prosecution of wars. These chapters recount some well-known (and some lesser known) historical events in which plants have played a central role. This book uniquely combines the modern scientific knowledge of plants with the human history of war, introducing readers to a new paradigm that will make them reconsider their understanding of human history, as well as to bring about a greater appreciation of plant biology.

The restoration of the flower gardens at Monticello in 1941, sponsored by the Garden Club of Virginia, was the result of Edwin Betts's scholarly research and Hazlehurst Perkins's practical gardening skills. Thomas Jefferson's Flower Garden at Monticello presents the evolution of Jefferson's ornamental gardening efforts with an analysis of the flower gardens as they were planned, planted, and ultimately restored.

No early American gardens were as well-documented as those at Monticello, which became an experimental station, a botanic garden of new and unusual plants from around the world. Betts and Perkins communicate here the nature and sources of Jefferson's intelligent venture into ornamental gardening.

The third edition includes a revised plant list, annotation of the more than 100 species cultivated in the flower garden, and new illustrations.

Wild Edible Underutilized Plants explores the role of wild plants in human nutrition-a topic that continues to take precedence in various fields of research. Despite the increasing evidence on past and present nutritional roles of wild edible plants, the use of these resources is often overlooked and neglected in countless policy areas. This book emphasizes the importance of these plants and explores their relevance to sustainable agriculture, biodiversity, and public health in different agro-ecological regions. The book implements a conceptual approach to wild plants, focusing on the benefits of incorporating these plants into people's diets and daily lives and the advantage they will provide to future generations. The book also addresses widespread issues of scarcity, proposing solutions that promote food sovereignty and security. The book begins by first discussing the nutritional aspects of wild edible plants to explore their value as a source of vitamins, antioxidants, fiber, minerals, and other nutrients. It then continues to elaborate on the anti-nutritional elements of these plants, providing a comprehensive overview of their utility.

With the increased interest in and demands for compost from commercial horticultural industries, composting is on the verge of becoming an economically feasible option for waste management. While horticultural producers can create some of the compost to meet their own needs, demand has grown beyond what they can supply for themselves and others. Compost Utilization in Horticultural Cropping Systems gives you the tools to meet the needs of this growing industry.
Consider these statistics:
o Americans generate about 200 million megagrams of municipal solid waste per year
o The agricultural market for compost could reach over 680 million m3 per year
o Two horticultural areas together account for over 50% of compost use: landscaping (31%) and food crop production (25%)
Now consider this:
o Proven benefits of compost use, including plant disease suppression, better moisture retention, supplying plant nutrients, and building soil organic matter
o Increased pressure on peat supplies and wider availability of compost products
o Creation of composting enterprises by the horticultural industry in response to its own needs, rising disposal fees for organic waste, and consumer demand for compost at retail centers
The first book to establish a composite of the existing scientific knowledge on the use of compost in commercial horticultural enterprises, Compost Utilization in Horticultural Cropping Systems gives you a comprehensive review of the production, use, and economics of compost. It covers production methods, compost quality and the parameters associated with its measurement, and the biological, chemical, and physical processes that occur during composting. Rather than searching for information in various places, now you can find all the information you need in one convenient source.

This text reflects the immense current growth in interest in agroecology and changing approaches to it. While it is acknowledged that the science of ecology should be the basis of agroecological planning, many analysts have out-of-date ideas about contemporary ecology. Ecology has come a long way since the old days of "the balance of nature" and other romantic notions of how ecological systems function. In this context, the new science of complexity has become extremely important in the modern science of ecology. The problem is that it tends to be too mathematical and technical and thus off-putting for the average student of agroecology, especially those new to the subject. Therefore this book seeks to present ideas about ecological complexity with a minimum of formal mathematics. The book's organization consists of an introductory chapter, and a second chapter providing some of the background to basic ecological topics as they are relevant to agroecosystrems (e.g., soil biology and pest control). The core of the book consists of seven chapters on key intersecting themes of ecological complexity, including issues such as spatial patterns, network theory and tipping points, illustrated by examples from agroecology and agricultural systems from around the world.

Farmers have developed a range of agricultural practices to sustainably use and maintain a wide diversity of crop species in many parts of the world. This book documents good practices innovated by farmers and collects key reviews on good practices from global experts, not only from the case study countries but also from Brazil, China and other parts of Asia and Latin America. A good practice for diversity is defined as a system, organization or process that, over time and space, maintains, enhances and creates crop genetic diversity, and ensures its availability to and from farmers and other users. Drawing on experiences from a UNEP-GEF project on "Conservation and Sustainable Use of Wild and Cultivated Tropical Fruit Tree Diversity for Promoting Livelihoods, Food Security and Ecosystem Services", with case studies from India, Indonesia, Malaysia and Thailand, the authors show how methods for identifying good practices are still evolving and challenges in scaling-up remain. They identify key principles effective as a strategy for mainstreaming good practice into development efforts. Few books draw principles and lessons learned from good practices. This book fills this gap by combining good practices from the research project on tropical fruit trees with chapters from external experts to broaden its scope and relevance.

Swathes of the human world are covered in ornamental grass lawns; they are the single most commonly encountered horticultural feature on the planet. Unfortunately, they are now often viewed as resource-draining green deserts due to the lack of plant and animal diversity, the need for frequent mowing and watering, and addition of lawn greening products to keep them looking at their best. It is a venerable horticultural feature that is essentially frozen in time, and with few alternatives to whet the appetite, the lawn has languished in its current grass-only format for decades. Until now. Tapestry lawns are a new, practically researched and timely development of the ornamental lawn format that integrates both horticultural practice and ecological science and re-determines the potential of a lawn. Mown barely a handful of times a year and with no need for fertilisers or scarifying, tapestry lawns are substantially richer in their diversity of plant and animal life compared to traditional grass-only lawns and see the return of flowers and colour to a format from which they are usually purposefully excluded. Tapestry Lawns: Freed from Grass and Full of Flowers traces the changes in the lawn format from its origins to the modern day and offers information on how and why the tapestry lawn construct is now achievable. It provides guidance on how to create and maintain a tapestry lawn of your own and champions the potential benefits for wildlife that can follow. Features Accessible and informative to all types of readers from academic to amateur Includes a refined and tested set of useful tapestry lawn plants Contains step-by-step instructions for creation and management methods of grass-free lawns Illustrated in full colour If you have ever thought about mowing your lawn much less, making it much more colourful and wildlife friendly, then this book will inform and guide you to create a perfect, grass-free lawn.
