Put Theory into Practice Scarcity of natural resources, higher costs, higher demand, and concerns about environmental pollution- under these circumstances, improving food supply worldwide with adequate quantity and quality is fundamental. Based on the author's more than forty years of experience, The Use of Nutrients in Crop Plants
"The book...is, in fact, a short text on the many practical problems...associated with translating the explosion in basic biotechnological research into the next Green Revolution," explains Economic Botany. The book is "a concise and accurate narrative, that also manages to be interesting and personal...a splendid little book." Biotechnology states, "Because of the clarity with which it is written, this thin volume makes a major contribution to improving public understanding of genetic engineering's potential for enlarging the world's food supply...and can be profitably read by practically anyone interested in application of molecular biology to improvement of productivity in agriculture."
Until recently, breeding efforts in mass produced food crops centered on high yield production, yet sacrificed flavor, taste, and other qualities. Now, more emphasis is being placed on the enhancement of nutritional and medicinal properties as well as from an environmental impact and sustainability standpoint. This volume looks at the use of crops
Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.
This anchor volume to the series Managing Global Genetic Resources examines the structure that underlies efforts to preserve genetic material, including the worldwide network of genetic collections; the role of biotechnology; and a host of issues that surround management and use. Among the topics explored are in situ versus ex situ conservation, management of very large collections of genetic material, problems of quarantine, the controversy over ownership or copyright of genetic material, and more.
Since photosynthetic performance is a fundamental determinant of yield in the vast majority of crops, an understanding of the factors limiting photosynthetic productivity has a crucial role to play in crop improvement programmes. Photosynthesis, unlike the majority of physiological processes in plants, has been the subject of extensive studies at the molecular level for many years. This reductionist approach has resulted in the development of an impressive and detailed understanding of the mechanisms of light capture, energy transduction and carbohydrate biosynthesis, processes that are clearly central to the success of the plant and the productivity of crops. This volume examines in the widest context the factors determining the photosynthetic performance of crops. The emphasis throughout the book is on the setting for photosynthesis rather than the fundamental process itself. The book will prove useful to a wide range of plant scientists, and will encourage a more rapid integration of disciplines in the quest to understand and improve the productivity of crops by the procedures of classical breeding and genetic manipulation.
The improvement of crop species has been a basic pursuit since cultivation began thousands of years ago. To feed an ever increasing world population will require a great increase in food production. Wheat, corn, rice, potato and few others are expected to lead as the most important crops in the world. Enormous efforts are made all over the world to document as well as use these resources. Everybody knows that the introgression of genes in wheat provided the foundation for the “Green Revolution”. Later also demonstrated the great impact that genetic resources have on production. Several factors are contributing to high plant performance under different environmental conditions, therefore an effective and complementary use of all available technological tools and resources is needed to meet the challenge.
A biography of a staple grain we often take for granted, exploring how wheat went from wild grass to a world-shaping crop. At breakfast tables and bakeries, we take for granted a grain that has made human civilization possible, a cereal whose humble origins belie its world-shaping power: wheat. Amber Waves tells the story of a group of grass species that first grew in scattered stands in the foothills of the Middle East until our ancestors discovered their value as a source of food. Over thousands of years, we moved their seeds to all but the polar regions of Earth, slowly cultivating what we now know as wheat, and in the process creating a world of cuisines that uses wheat seeds as a staple food. Wheat spread across the globe, but as ecologist Catherine Zabinski shows us, a biography of wheat is not only the story of how plants ensure their own success: from the earliest bread to the most mouthwatering pasta, it is also a story of human ingenuity in producing enough food for ourselves and our communities. Since the first harvest of the ancient grain, we have perfected our farming systems to grow massive quantities of food, producing one of our species’ global mega crops—but at a great cost to ecological systems. And despite our vast capacity to grow food, we face problems with undernourishment both close to home and around the world. Weaving together history, evolution, and ecology, Zabinski’s tale explores much more than the wild roots and rise of a now-ubiquitous grain: it illuminates our complex relationship with our crops, both how we have transformed the plant species we use as food, and how our society—our culture—has changed in response to the need to secure food sources. From the origins of agriculture to gluten sensitivities, from our first selection of the largest seeds from wheat’s wild progenitors to the sequencing of the wheat genome and genetic engineering, Amber Waves sheds new light on how we grow the food that sustains so much human life.
Historical Geography of Crop Plants is devoted to a variety of staple and food crops, as well as fodder, fiber, timber, rubber, and other crops. The origins and histories of many of these crops have been clarified only recently by new research. The book has been arranged alphabetically by family and higher taxa for easy reference. Within families, species and cultivars are listed chronologically and geographically. The taxonomy and geography of probable wild progenitors have been outlined, and archeological evidence (when available) and historical evidence on region and domestication are traced. The subsequent evolution and spread of many domesticated species are examined, and the reasons behind the diversity in crop histories are explored. Historical Geography of Crop Plants will be a useful reference for botanists, economic botanists, ethnobiologists, agronomists, geographers, and others interested in the subject.
