Spices, scents and silks were at the centre of world trade for millennia. Exotic luxuries such as cinnamon, ginger, pepper, saffron, clove, frankincense and myrrh. Through their international trade, humans were pushed to explore and then travel to the far corners of the earth. Almost from their inception, the earliest great civilizations - Egypt, Sumer and Harappa - became addicted to the luxury products of far-off lands and established long-reaching trade networks. Over time, great powers fought mightily for the kingdoms where silk, spices and scents were produced. The New World was accidentally discovered by Columbus in his quest for spices. What made trade in these products so remarkable was that the plants producing them grew in very restricted areas of the world, distant from the wealthy civilizations of northern Africa, Greece and Europe. These luxuries could be carried from mysterious locations on the backs of camels or in the holds of ships for months on end, and arrived at their final destination in nearly perfect condition. Once the western world discovered the intoxicating properties of these products, their procurement became a dominant force in the world economy. Nothing else compared with their possible profit returns. In this book, eminent horticulturist and author James Hancock examines the origins and early domestication and culture of spices, scents and silks and the central role they played in the lives of the ancients. The book also traces the development of the great international trade networks and explores how struggles for trade dominance and demand for such luxuries shaped the world. Recommended for academics, students and general readers with an interest in crop and agricultural development, world trade, economic botany, history of food, and global economics and public policy, Spices, Scents and Silk offers a fascinating and insightful history.

This second edition of Natural Enemies will give students, professionals, and anyone wishing to learn the basics of biological control a fully updated and thorough introduction. The book discusses the huge diversity of organisms used in the control of pests, weeds and plant pathogens, and compares the many different strategies referred to as 'biological control': the introduction of exotic natural enemies, application of predators, parasitoids, and microorganisms as biopesticides, and manipulation of the environment to enhance natural enemy populations. The authors present the ecological concepts which form the bases of biological control and discuss recent changes to make biological control safe for the environment. Case studies are included throughout, providing in-depth examples of the use of different organisms and strategies in a variety of ecosystems. A new chapter covers the current challenges; the impact of climate change, the problem of invasive species, and how biological control can aid sustainability.

Grasslands, in particular managed pastures and rangelands, are widespread, covering approximately 40% (52 million km2) of the Earth's land surface. They are dominated by members of the Poaceae - the fourth largest plant family with over 7,500 species, and also the most widespread. Grasslands constitute a major biome on all continents except Antarctica and also represent the most important food crop on Earth with corn, wheat, maize, rice and millet accounting for the majority of our agricultural output.
Grasses and Grassland Ecology provides an ecologically orientated introduction to this influential group of plants, summarizing the most recent scientific research in ecology and agriculture in the context of the older, classic literature. Ten chapters cover the morphology, anatomy, physiology and systematics of grasses, their population, community and ecosystem ecology, their global distribution, and the effects of disturbance and grassland management.
This comprehensive and accessible textbook is suitable for graduate level students as well as professional researchers in the fields of plant ecology, rangeland science, crop science, and agriculture.

Agroecology is defined as the application of ecological concepts and principles to the design and management of sustainable food systems. Hence, learning can best be achieved through an experiential approach to the topic. Designed to accompany Agroecology: The Ecology of Sustainable Food Systems, Third Edition, Field and Laboratory Investigations in Agroecology, Third Edition features 24 investigations divided into five sections that parallel the main text: Studies of Environmental Factors: These investigations deal with how an individual plant responds to the environment, how environmental factors in specific agroecosystems are measured and characterized, and how particular environmental factors affect individual plants. Studies of Population Dynamics in Crop Systems: This section studies how populations of organisms act in agroecosystems. It focuses on what populations are present, how they change over time and respond to the environment, and how individuals within a population may interact. Studies of Interspecific Interactions in Cropping Communities: This section emphasizes the between-species interactions of the organisms that make up crop communities. These interactions include herbivory, allelopathy, and mutualisms. Studies of Farm and Field Systems: These investigations cover system-level agroecology and whole farms or systems within farm boundaries. They touch on the complexity with which the farmer deals in managing agroecosystems. Food System Studies: These investigations reach out beyond the individual farm to examine components of the food system at a local level, which impact all of the levels of analysis in the first four parts. This manual facilitates hands-on learning that involves close observation, creative interpretation, and constant questioning of findings. The investigations emphasize the importance of careful data interpretation and presentation and the value of a clear, concise, and well-written research report. The book uses simple statistical analysis for data management and interpretation and students are guided through the steps of data analysis in the context of the particular investigations in which it is employed.

Dies ist kein Buch iiber den Hunger in der "Dritten Welt" oder die EiweiB-Annut der Tropenbevolkerung. Es ist vielmehr dem natiir- lichen Reichtum der Tropen und Subtropen gewidmet. Einerseits handelt es von der Phylogenese und Domestikation der konventio- nellen tropischen Kulturpflanzen, beschreibt aber andererseits auch bisher wenig bekannte wilde und semi-kultivierte Gewachse, deren fortschreitende Selektion das Spektrum von Nutzpflanzen in den Aquatorialzonen bereichem wiirde. Ihre beschleunigte Domestika- tion aufgrund der neuzeitlichen Fortschritte in der Strahlengenetik, experimentellen Zytologie und Mutationsziichtung konnte eine Rei- he von Versaumnissen gutmachen, unter denen die gegenwartige Tropenlandwirtschaft leidet, und zur Milderung zahlreicher Proble- me der "Dritten Welt" beitragen. Die Anregungen zu diesem Buch gehen auf meine Spezialvorle- sungen und eigene langjahrige Experimentalarbeiten zuriick, die ich im Verlauf von drei lahrzehnten an mehreren Universitaten und Saatzuchtstationen der Alten und Neuen Welt durchgefUhrt habe. Das Geriist dieser Arbeit bilden ausgedehnte Sammelreisen und Ex- peditionen in den aquatorialen Breiten von Afrika, Amerika und Asien, die mir vor allem solche Kenntnisse vermittelten, die von weitverbreiteten Lehrbuchmeinungen abweichen.

Including recipes for baking with Einkorn Wheat is the most widely grown crop on our planet, yet industrial breeders have transformed this ancient staff of life into a commodity of yield and profit-witness the increase in gluten intolerance and 'wheat belly'. Modern wheat depends on synthetic fertilizer and herbicides that damage our health, land, water, and environment. Fortunately, heritage 'landrace' wheats that evolved over millennia in the organic fields of traditional farms do not need bio-chemical intervention to yield bountifully, are gluten-safe, have rich flavor and high nutrition. Yet the robust, majestic wheats that nourished our ancestors are on the verge of extinction. In Restoring Heritage Grains, author Eli Rogosa of the Heritage Grain Conservancy, invites readers to restore forgotten wheats such as delicious gluten-safe einkorn that nourished the first Neolithic farmers, emmer-the grain of ancient Israel, Egypt, and Rome that is perfect for pasta and flatbreads, rare durums that are drought-tolerant and high in protein, and many more little known wheat species, each of which have a lineage intertwined with the human species and that taste better than any modern wheat. Restoring Heritage Grains combines the history of grain growing and society, in-depth practical advice on landrace wheat husbandry, wheat folk traditions and mythology, and guidelines for the Neolithic diet with traditional recipes for rustic bread, pastry and beer. Discover the ancient grains that may be one of the best solutions to hunger today, and provide resilience for our future.

For over four decades, John Coykendall's passion has been preserving the farm heritage of a small community in rural southeastern Louisiana. A Tennessee native and longtime master gardener at Blackberry Farm, Coykendall has become a celebrity in a growing movement that places a premium on farm-to-table cuisine with locally sourced, organic, and heirloom foods and flavors. While his work takes him around the world searching for seeds and the cultural knowledge of how to grow them, what inspires him most is his annual pilgrimage to Louisiana. Drawn to the Washington Parish area as a college student, Coykendall forged long-lasting friendships with local farmers and gardeners. Over the decades, he has recorded oral histories, recipes, tall tales, agricultural knowledge, and wisdom from generations past in more than eighty illustrated and handwritten journals. At the same time, he has unearthed and safeguarded rare varieties of food crops once grown in the area, then handed them back to the community. In Preserving Our Roots: My Journey to Save Seeds and Stories, Coykendall shares a wealth of materials collected in his journals, ensuring they are passed on to future generations. organised by season, the book offers a narrative chronicle of Coykendall's visits to Washington Parish since 1973. He highlights staple crops, agricultural practices, and favourite recipes from the families and friends who have hosted him. Accompanied by a rich selection of drawings, journal pages, and photographs, along with over forty recipes, Preserving Our Roots chronicles Coykendall's passion for recording foods and narratives that capture the rhythms of daily life on farms, in kitchens, and across generations.

Spices provide our food with nutraceutical value rather than actual nutrition. But apart from the popular and major spices, there are several other spices, which, in spite of their enormous contribution to human health, remain underexploited or underutilized.

It will include in-depth narration on underexploited spice crops as products in influencing present-day the global export market and the renewed interest in these crops throughout the world. The volume deals with the scientific approach of growing underexploited spices with the intention of popularizing them. Separate chapters on the importance of each spice, methods of growing and harvesting, and recent research from around the world along with future strategies are covered.

Peanut Agriculture and Production Technology: Integrated Nutrient Management focuses on agricultural techniques and integrated nutrient management of peanuts (Arachis hypogaea L.). Peanuts are the second most important oil crop of India, occupying 5.7 million hectares, with an average production of 0.8 ton/ha, which is 23.5% of the India's total oil seed production. Worldwide annual production of shelled peanuts was 42 million metric tons in 2014. It is the world's 4th most important source of edible oil and the 3rd most important source of vegetable protein. The volume includes basic and advanced information on production, agrotechniques, and integrated nutrient management of Arachis hypogaea L. crop plant. It studies the physiology of the peanut, looking at the proper environmental conditions for optimal growth as well as under various subnormal conditions. It explores the methods of nitrogen application as well as the influence of different sowing dates and population densities to harvest its full yield potential. The book covers methods to achieve balanced nutrition, including using organic manures in groundnut farming to enhance yielding ability. The book will be a rich resource for those in agriculture, horticulture, and allied sciences, particularly for agricultural scientists in plant and crop physiology, agronomy, and soil science. Farm owners and managers of peanut crops and production will also benefit from the information provided in this volume.

Making hay has always been hard work, just about the hardest work on a farm. Spanning 150 years, The Haymakers tells a story of the labor and heartbreak suffered by five families struggling to make the hay that fed their livestock, a story not just about grass, alfalfa, and clover, but also about sweat and fears, toil and loss. The Haymakers is an epic -- the history of man's struggle with nature as well as man's struggle against machines. It relates the story of farmers and their obligations to their families, to the animals they fed, and to the land they tended.

Hoffbeck also documents and preserves the commonplace methods of haymaking. He describes the tools and the methods of haymaking as well as the relentless demands of the farm. Using diaries, agricultural guidebooks and personal interviews, the folkways of cutting, raking, and harvesting hay have been recorded in these chapters. In the end, this book is not so much about agricultural history as it is about family history, personal history -- how farm families survive, even persevere.
