Food security and environmental conservation are two of the greatest challenges facing the world today. It is predicted that food production must increase by at least 70% before 2050 to support continued population growth, though the size of the world's agricultural area will remain essentially unchanged. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues. Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists.

Until recently, breeding efforts in mass produced food crops centered on high yield production while sacrificing flavor, taste and other quality traits. Now, more emphasis is being placed on the enhancement of nutritional and medicinal properties of the food crops. Aside from merely being considered a source of food, crops are today being looked from a health benefit perspective and even from an environmental standpoint. This volume looks at the use of crops for a myriad of purposes, including the prevention and/or mitigation of various diseases, vaccine and antigen production, biofuel production, and the suppression of weeds.

The fast-growing sugarcane plant is a major source of sugar (sucrose) in tropical and sub-tropical regions. The high productivity of the plant also makes it a key target for use as an energy crop. The fiber of the plant is used to generate electricity and produce ethanol as a fuel. Sugarcane is a hybrid of two species, each of which is genetically complex. The high level of genetic complexity in sugarcane creates challenges in the application of both conventional and molecular breeding to the genetic improvement of sugarcane as a sugar and energy crop. This book describes technologies that support the continued use and improvement of sugarcane as source of food and energy. Recent technology developments indicate the potential to greatly increase our understanding of the sugarcane plant by application of emerging genomic technologies. This should result in an increased rate of improvement of sugarcane for human uses.

Over the past fifty years plant breeders have achieved impressive improvements in yield, quality and disease resistance. These gains suggest that many more modifications might be introduced if appropriate genes can be identified. Current DNA techniques allow the construction of transgenic plants and this important new book reviews the current state of knowledge. A team of leading researchers provide in-depth reviews at the cutting edge of technology for laboratory techniques for the transformation of important soil microorganisms and recalcitrant plants of economic value. The book is divided into three sections: soil microorganisms; cereal crops; and industrially important plants. The most effective methods used to date are compared, and their merits and limitations discussed. Some chapters emphasise case studies and applications. In cases where obstacles remain to be overcome, an overview of progress to date is given. The book will serve as a general guide and reference tool for those working on transformation in microbiology and plant science.

In use as a medicinal plant since time immemorial in Europe and the Middle East, chamomile is gaining popularity in the Americas, Australia, and Asia. The spectrum of disease conditions in which it is used in traditional medicine systems is, quite simply, mind boggling. There is, without a doubt, a growing demand for this plant and therefore a growing need for an updated ready reference for the researchers, cultivators, and entrepreneurs who wish to work with chamomile. Chamomile: Medicinal, Biochemical, and Agricultural Aspects is just that. Based on extensive research, this book provides the latest information on the medicinal, aromatic, and cultivation aspects of chamomile. It covers chamomile's geographical distribution, taxonomy, chemistry, pharmacology, genetics, biochemistry, breeding, and cultivation. The book also discusses the profiles of the several medicinally active compounds of the oil and extracts and how their levels could be increased through breeding. The author highlights several potentially useful compounds discovered in the chamomile oil and extracts and discusses the cultivation and postharvest technology aspects of the plant in different agroclimatic zones including that of India. She presents guidelines on the good manufacturing practices laid out in different systems of medicine and provides an overview of the patents and products of chamomile especially important to researchers and entrepreneurs. Although there is a plethora of information available on chamomile, the challenge has been finding a central repository that covers all aspects of the plant. Some books provide general coverage, others focus on only on pharmacological uses, and many are outdated. This book examines all aspects from cultivation and harvesting, to essential oil content and profile as well as pharmacology and biotechnology. It is a reference for current information, an entry point for further study, a resource for using oils and extr

Global demand for wheat, rice, corn, and other essential grains is expected to steadily rise over the next twenty years. Meeting this demand by increasing production through increased land use is not very likely; and while better crop management may make a marginal difference, most agriculture experts agree that this anticipated deficit must be made up through increased crop yields. The first resource of its kind, Physiology and Biotechnology Integration for Plant Breeding assembles current research in crop plant physiology, plant biotechnology, and plant breeding that is aimed toward improving crop plants genetically while supporting a productive agriculture ecosystem. Highly comprehensive, this reference provides access to the most innovative perspectives in crop physiology - with a special emphasis on molecular approaches - aimed at the formulation of those crop cultivars that offer the greatest potential to increase crop yields in stress environments. Surveys the current state of the field, as well as modern options and avenues for plant breeders and biotechnologists interested in augmenting crop yield and stability With the contributions of plant scientists from all corners of the globe who are actively involved in meeting this important challenge, Physiology and Biotechnology Integration for Plant Breeding provides readers with the background information needed to understand this cutting-edge work, as well as detailed information on present and potential applications. While the first half of the book establishes and fully explains the link between crop physiology and molecular biology, the second part explores the application of biotechnology in the effective delivery of the high yield and environmentally stable crop plants needed to avert the very real possibility of worldwide hunger.

It is predicted that the world population will reach about 9.7 billion by the year 2050 and to feed this population the food production has to be increased proportionately. Further we are all concerned about climate which in turn results in abiotic stresses like drought, salinity, etc. These abiotic stresses will seriously affect crop productivity. This approach has gained popularity in the recent years and seems to be a potential option for the future. The present book brings out the role of different groups of microorganisms in alleviating abiotic stress in crop plants. Please note: This volume is Co-published with New India Publishing Agency, New Delhi. Taylor & Francis does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka

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.

Saffron is a precious spice which is mainly grown in Iran, India, Spain, Greece, Italy, Pakistan, Morocco, and central Asian countries.

The book presents a comprehensive account of saffron which includes the historical background, acerage underproduction, yield and applications, botanical ecophysiology, production technology, irrigation, pests, diseases and weeds, genetics, sterility, reproduction and production of secondary metabolites by in vitro method, economic aspects, indigenous knowledge in saffron production, processing, chemical composition and quality control, and research strategies.

1.1. INTRODUCTION Plastic covering, either framed or floating, is now used worldwide to protect crops from unfavorable growing conditions, such as severe weather and insects and birds. Protected cultivation in the broad sense, including mulching, has been widely spread by the innovation of plastic films. Paper, straw, and glass were the main materials used before the era of plastics. Utilization of plastics in agriculture started in the developed countries and is now spreading to the developing countries. Early utilization of plastic was in cold regions, and plastic was mainly used for protection from the cold. Now plastic is used also for protection from wind, insects and diseases. The use of covering techniques started with a simple system such as mulching, then row covers and small tunnels were developed, and finally plastic houses. Floating mulch was an exception to this sequence: it was introduced rather recently, although it is a simple structure. New development of functional and inexpensive films triggered widespread use of floating mulch. Table 1.1. The use a/plastic mulch in the world (after Jouet, 2001).
