By the year 2050, the world's population is expected to reach nine billion. To feed and sustain this projected population, world food production must increase by at least 50 percent on much of the same land that we farm today. To meet this staggering challenge, scientists must develop the technology required to achieve an "evergreen" revolution-one
Fungicides for Field Crops provides an overview of the current knowledge of fungicides and their use on field crops. This comprehensive book, which includes the contributions of 40 professionals from 20 universities and other organizations, combines past knowledge about fungicides with recent developments in the realm of field crop fungicides. Fungicides for Field Crops highlights the use of fungicides as key tools in the management of important diseases of field crops. Management is presented as a decision-making process--one in which factors as diverse as weather conditions and economics must be considered. Having a more complete understanding of fungicides will inform that decision making and help determine when fungicides should be included as part of a management plan. Parts I, II, and III establish a foundation of knowledge about fungicide use, addressing basic terms and concepts, key factors in decision making, and concerns for fungicide stewardship, respectively. Part IV presents details about using fungicides to manage diseases of 16 field crops. Each crop is treated in a separate section that begins with a discussion of general issues of foliar application and seed treatment and ends with an inclusive table identifying diseases of that crop, including what causes them and how fungicides may be used to treat them. 131 color photographs illustrate disease symptoms and show techniques and enhance the key concepts described in the text.

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.
Outlining successful breeding techniques to augment the yields of the world's major crops, this reference analyzes the physiological and genetic basis for past and potential future increases in crop yields.;Covering crops with wide differences in morphology, photosynthetic rates, and nitrogen metabolisms, Genetic Improvement of Field Crops: investigates the changes produced by breeders in the physiological attributes affecting wheat grain yield and nitrogen content during the last century; discusses those crop characteristics of oats that have already been altered or might be manipulated through breeding to further increase yield potential; describes several genetic factors responsible for both yield potential and stress resistance in barley; offers insights into the relationship between increases in the yield potential and stress tolerance of corn; examines the evolution of sunflower crop yields and yield stability and estimates the contribution of improved cultivars; evaluates the effects of breeding on tuber characteristics related to the crop growth and yield of the potato; elucidates the possibilities for simultaneous improvement of yield and fiber strength in cotton; and identifies the features to be considered in the development of high yielding varieties of rice for different agricultural systems.;Providing nearly 1600 key literature citations allowing further in-depth study of particular topics, Genetic Improvement of Field Crops is for plant physiologists and breeders, crop and agricultural scientists, agronomists, biochemists, geneticists, biotechnologists, microbiologists, and upper-level undergraduate and graduate students in these disciplines.
This book discusses the most challenging task ahead of researchers from India and around the globe: providing disease-free field crops for the ever-growing world population. In Asia, despite being cultivated in massive volumes, major crops, including cereals, oil seed, tuber and non-tuber vegetables, and fruit, are not meeting the demands of the increasing population. This book showcases naturally occurring beneficial microbes in the form of plant growth promoting rhizobacteria, or PGPR, which make it possible to grow field crops without applying synthetic chemicals. Our understanding of PGPR has increased exponentially in recent decades. They play a multifarious role in developing sustainable systems of crop production and protection. The book focuses on the mechanistic behaviors of PGPRs, their use to develop sustainable cultivation techniques, and their application to enhance crop growth and productivity at the cutting edge of tech-oriented agriculture and to replace hazardous chemicals with microbial inoculants. The book is useful to agronomists, microbiologists, ecologists, plant pathologists, molecular biologists, environmentalists, policy makers, conservationists, and NGOs working on organically grown field crops.
Nutrient imbalance in soils is an emerging threat to sustainable agriculture: intensive cultivation, use of poor quality groundwater, depletion of soil organic matter and excessive use of fertilizers are major reasons for poor soil fertility worldwide. This necessitates correct diagnosis of plant nutrient deficiencies to avoid further use of pesticides in cases where pests or pathogens that are not in fact the cause of poor crop health. Richly illustrated with 600 colour photographs, this book is a visual field identification guide for symptoms of most common nutrient deficiencies in field crops, covering all their stages of occurrence. Detailed descriptions and suggested for management practices are given with each entry.
While preparing the first edition of this textbook I attended an extension short course on writing agricultural publications. The message I remember was "select your audience and write to it. " There has never been any doubt about the audience for which this textbook was written, the introductory course in crop breeding. In addition, it has become a widely used reference for the graduate plant-breeding student and the practicing plant breeder. In its prepa ration, particular attention has been given to advances in plant-breeding theo ry and their utility in plant-breeding practice. The blend of the theoretical with the practical has set this book apart from other plant-breeding textbooks. The basic structure and the objectives of the earlier editions remain un changed. These objectives are (1) to review essential features of plant re production, Mendelian genetic principles, and related genetic developments applicable in plant-breeding practice; (2) to describe and evaluate established and new plant-breeding procedures and techniques, and (3) to discuss plant breeding objectives with emphasis on the importance of proper choice of objec tive for achieving success in variety development. Because plant-breeding activities are normally organized around specific crops, there are chapters describing breeding procedures and objectives for the major crop plants; the crops were chosen for their economic importance or diversity in breeding sys tems. These chapters provide a broad overview of the kinds of problems with which the breeder must cope.
The use of organic management practices in field cropping continues to rise globally, and these methods have proven to be a viable way to produce food with reduced resource use and environmental damage. Managing Energy, Nutrients, and Pests in Organic Field Crops challenges the popular misconception that organic systems are weak at managing energy, nutrients, and pests and shows how innovative farm designs can enhance organic performance. It provides information for assessing the current state of knowledge on organic field cropping and for making the systems more viable. Each chapter summarizes the latest data from a wide range of sources, creating a comprehensive and coherent picture of the issues and integrating agronomic, economic, and policy aspects. Many chapters also include recent research from the authors. Section I, Soil Health, examines the importance of phosphorus balance, soil fertility, and tillage reduction. Section II, Pest Management, focuses on integrated weed management and long-term approaches to insect management. Section III, Integrating Approaches, addresses multiple field cropping challenges. Chapters cover the oldest organic rotational trials in Canada, the issue of using cereals bred for conventional systems and more targeted organic cereal breeding strategies, and case studies of a broad spectrum of farming experiences that explore the broader social and ecological landscape. The final section, Economics, Energy, and Policy, examines environmental issues not previously addressed in the text as well as consumer, economic, and rural community matters. It also presents a reprint of an article that describes policies and programs (and their costs) needed to advance adoption of organic farming in Ontario. The text wraps up with key conclusions and a discussion of overarching themes for the book, summarizing the strengths of the available tool box for organic producers and the challenges that remain.
The majority of meat, milk, and eggs consumed in the United States are produced in concentrated animal feeding operations (CAFO). With concentrated animal operations, in turn comes concentrated manure accumulation, which can pose a threat of contamination of air, soil, and water if improperly managed. Animal Manure: Production, Characteristics, Environmental Concerns, and Management navigates these important environmental concerns while detailing opportunities for environmentally and economically beneficial utilization.
