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.

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 that increases crop productivity without degrading natural resources. With 30 percent new material, the updated and revised third edition of Growth and Mineral Nutrition of Field Crops covers all aspects of crop growth and mineral nutrition that contribute to sustainable, high-yield agriculture. Bringing together international scientific knowledge of crop production and the impacts of agriculture on the environment, this book: * Includes two new chapters on remediation of heavy-metal contaminated soils and cover crops * Covers theoretical and practical aspects of mineral nutrition of field crops * Provides recommendations for judicious use of fertilizers, which will reduce cost of crop production and enhance high crop yields without risking environmental pollution * Provides growth patterns for annual crops and forages * Includes a handful of color pictures of nutrient deficiencies for easy diagnostic purposes To make the book as practical as possible, each chapter is supported by experimental results and extensive references. A large number of figures and tables are also included to save readers time when researching. The overall emphasis of this reference is on the soil's ability to sustain high crop yields and a healthy human population.

Part 3 looks further along the value chain at ways of optimising cultivation practices. There are chapters on post-harvest storage as well as fungal diseases, weeds and integrated methods for their management. The final part of the book assesses current developments in optimising barley for particular end uses such as malting, brewing and animal feed as well as current research on the nutraceutical properties of barley.

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.

The final part of the book reviews research on optimising fertiliser use. Chapters cover topics such as assessing nutrient availability and advances in integrated plant nutrient management. Other chapters discuss enhanced efficiency fertilisers, the use of bio-effectors/bio-stimulants, fertigation techniques, foliar fertilizers and the use of treated wastes in crop nutrition.

A study of the productivity of land in the bishopric of Winchester from 1208 to 1350. To a student of agrarian society and economy the knowledge of changes in the productivity of land is a crucial factor. For the Middle Ages, only England has the right type of documents - the manorial accounts - to allow cereal yields to be calculated with any degree of exactness. The accounts of the bishopric of Winchester occupy a very special position. This collection not only antedates all others by some 50 years, but is also by far the best series of account rolls in existence and the only one allowing for a study covering the whole of the 13th century. Dr Titow presents the whole range of the Winchester yield calculations and also examines the observable changes in productivity in the light of other relevant factors.

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 2007, the first edition of Handbook of Plant Nutrition presented a compendium of information on the mineral nutrition of plants available at that time-and became a bestseller and trusted resource. Updated to reflect recent advances in knowledge of plant nutrition, the second edition continues this tradition. With chapters written by a new team of experts, each element is covered in a different manner, providing a fresh look and new understanding of the material. The chapters extensively explore the relationship between plant genetics and the accumulation and use of nutrients by plants, adding to the coverage available in the first edition. The second edition features a chapter on lanthanides, which have gained importance in plant nutrition since the publication of the first edition, and contains chapters on the different mineral elements. It follows the general pattern of a description of the determination of essentiality or beneficial effects of the element, uptake and assimilation, physiological responses of plants to the element, genetics of its acquisition by plants, concentrations of the element and its derivatives and metabolites in plants, interaction of the element with uptake of other elements, diagnosis of concentrations of the element in plants, forms and concentrations of the element in soils and its availability to plants, soil tests and fertilizers used to supply the element. The book demonstrates how the appearance and composition of plants can be used to assess nutritional status and the value of soil tests for assessing nutrition status. It also includes recommendations of fertilizers that can be applied to remedy nutritional deficiencies. These features and more make Handbook of Plant Nutrition, Second Edition a practical, easy-to-use reference for determining, monitoring, and improving the nutritional profiles of plants worldwide.

It is a valuable tool for improving crop yields at lower cost and less stress on the environment.

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.

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.

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).
