When one is privileged to participate long enough in a professional capacity, certain trends may be observed in the dynamics of how challenges are met or how problems are solved. Agricultural research is no exception in view of how the plant sciences have moved forward in the past 30 years. For example, the once grand but now nearly forgotten art of whole plant physiology has given way almost completely to the more sophisticated realm of molecular biology. What once was the American Society of Plant Physiologists' is now the American Society of Plant Molecular Biology; a democratic decision to indemnify efforts to go beyond the limits of the classical science and actually begin to understand the underlying biological basis for genetic regulation of metabolic mechanisms in plants. Yet, as new technologies open windows of light on the inner workings of biological processes, one might reminisce with faint nostalgia on days long past when the artisans of plant physiology, biochemistry, analytical chemistry and other scientific disciplines ebbed and waned in prominence. No intentional reference is made here regarding Darwinism; the plant sciences always have been extremely competitive. Technology is pivotal. Those who develop and/or implement innovative concepts typically are regarded as leaders in their respective fields. Each positive incremental step helps bring recognition and the impetus to push a scientific discipline forward with timely approaches to address relevant opportunities.

Reproductive biology is the basis of species improvement and a thorough understanding of this is needed for plant improvement, whether by conventional or biotechnological methods. This book presents an up to date and comprehensive description of reproduction in lower plants, gymnosperms and higher plants. It covers general plant biology, pollination, pollen-pistil interaction, post-fertilization changes, and seed dormancy.

An increased understanding of the developmental physiology, biochemistry, and molecular biology during early growth, maturation, ripening, and postharvest conditions has improved technologies to maintain the shelf life and quality of fruits, vegetables, and flowers. "Postharvest Biology and Technology of Fruits, Vegetables, and Flowers" provides a comprehensive introduction to this subject, offering a firm grounding in the basic science and branching out into the technology and practical applications. An authoritative resource on the science and technology of the postharvest sector, this book surveys the body of knowledge with an emphasis on the recent advances in the field.

"...a well-curated collection of chapters that provides a broad state-of-the-art survey of how roots contribute to plant crop performance and edaphic stress tolerance...Given the urgency to deploy sustainable and resilient agricultural technologies, this excellent collection demonstrates how novel approaches and collaborative trans-disciplinarity can prepare the field of root biology for transformative, real-world impacts." (Annals of Botany) Recent decades have seen a dramatic increase in research on plant roots. A deeper understanding of the complex ways roots interact with soils is making it possible to 'design' roots to optimise nutrient/water uptake in low-input environments, as well as deliver other benefits such as improved soil health and reduced nutrient leaching. Continued research is needed in this important area so that it can contribute to more sustainable, 'climate-smart' crop production. Understanding and improving crop root function features authoritative reviews of current research in all aspects of root science, including root growth regulators, root anatomy, nutrient acquisition and root system architecture. This collection discusses the responses of plant roots to abiotic and biotic stresses and how understanding nutrient uptake can be exploited to optimise root function. The book concludes with a dedicated section on methods used to improve crop root function and crop nutrient use efficiency, such as the use of plant growth-promoting rhizobacteria (PGPR). With its eminent editor and international array of expert authors, Understanding and improving crop root function will be a standard reference for university researchers in crop physiology and nutrition, government and other agencies supporting agriculture, companies supplying crop nutrition products and services, as well as farmers.

In a world of high finance, unprecedented technological change, and cyber billionaires, it is easy to forget that a major source of global wealth is, literally, right under our noses. Coffee is one of the most valuable Southern exports, generating billions of dollars in corporate profits each year, even while the majority of the world's 25 million coffee families live in relative poverty. But who is responsible for such vast inequality? Many analysts point to the coffee market itself, its price volatility and corporate oligarchy, and seek to "correct" it through fair trade, organic and sustainable coffee, corporate social responsibility, and a number of market-driven projects. The result has been widespread acceptance that the "market" is both the cause of underdevelopment and its potential solution. Against this consensus, Gavin Fridell provocatively argues that state action, both good and bad, has been and continues to be central to the everyday operations of the coffee industry, even in today's world of "free trade." Combining rich history with an incisive analysis of key factors shaping the coffee business, Fridell challenges the notion that injustice in the industry can be solved "one sip at a time" - as ethical trade promoters put it. Instead, he points to the centrality of coffee statecraft both for preserving the status quo and for initiating meaningful changes to the coffee industry in the future.

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 book synthesizes knowledge on the arthropod taxon Oribatida, a suborder of Acari (the mites and ticks), that are a key group in soil ecology and biodiversity studies for Canada and Alaska but also worldwide. This book is unparalleled in the comprehensive nature of the information provided on this key biotic group. It is presented by two leading global experts for this group. There is no competing text in English. Reviewers were unanimous in their view that there is an "unquestionable" need for this book. The book provides highly reliable set of data, well prepared from a content and methodological point of view, bringing much interesting information on the subject and a valuable contribution to the knowledge of ecology of the group of invertebrates.

The first systematic analysis of the early nineteenth-century allotment movement. The living standards of the rural poor suffered a severe decline in the first half of the nineteenth century as a result of high population growth, changing agricultural practices, enclosure and the decline of rural industries. Allotment provision was the most important counterweight to the pressures. This book offers the first systematic analysis of the early nineteenth-century allotment movement, providing new data on its chronology and on the number, geographical distribution, size, rents, cultivation yields and effect on living standards of allotments. It thus shows how the movement brought the culture of the rural labouring poor more closely into line with the mainstream values of respectable mid-Victorian England, and casts new light on central aspects of early and mid-nineteenth-century social and economic history, agriculture and rural society.

Grass is a very important world crop. In some countries, for example the UK, Australia and New Zealand, animal products from grassland make a greater contribution to the value of agricultural production than does any other crop. Yet research being undertaken to further. our understanding of the factors affecting the growth and productivity of grasslands has trailed in the shadow of the determined efforts made to improve our knowledge of cereals and, to a somewhat lesser extent, legumes. However, in spite of its low profile, grassland research has resulted in considerable advances in our knowledge in the last 20 years, and we feel that this book provides a timely opportunity to bring together some of this work in a review of what is primarily the ecophysiology of the temperate grass crop. Unlike other crops grown for their grain or vegatative parts, grass and grassland products are used almost entirely for the feeding of ruminant animals; the interaction of the sward and the animal thus adds an extra dimension to investigations of the productivity of grassland. No one author could adequately encompass the breadth of work covered in the book. Acknowledged experts have therefore been selected as contributors to provide an up-to-date review of their own specialized areas. Whilst multi author texts can cause problems of lack of uniformity of approach, each contributor has been made aware of the contents of the other chapters in an attempt both to provide continuity and to prevent glaring overlaps."

From prehistoric times man has had a pecial s relationship with seed plants - as a source of food, materials for tools, buildings, clothing and pharmaceuticals, and for ornamenting his surroundings for his own delight (probably in that chronological order which, incidentally, also gives some indication ofthe priorities oflife). Today man's most important staple foods are derived directly from seeds as they have been since neolithic times. (It is a sobering thought, as Harlan* has pointed out, that nothing significant has been added to his diet since then. ) From those times he must have learned to collect, conserve and cultivate seeds; and the accumulated experience has been handed down. This book then is part of an ancient tradition, for here we are still primarily concerned with these skills. Seeds are plant propagules comprised of embryos in which growth has been suspended, usually supplied with their own food reserves and protected by special covering layers. Typically they are relatively dry structures compared with other plant tissues and, in this condi tion) they are resistant to the ravages of time and their environment. But resistant is a relative tenn and seeds do deteriorate: the type, the extent and the rapidity of the deterioration, and the factors which control it are important to agronomists, horticulturalists, plant breeders, seedsmen, seed analysts, and those concerned with the conservation of genetic resources.

Crop water use can be increased by management of surface runoff, groundwater, irrigation, and soil water. Technological innovations to enhance availability of water for agricultural crops depend on soil and site-specific conditions. Devoted to the principles and practices of enhancing water use efficiency, Soil Water and Agronomic Productivity addresses current problems associated with water supplies required for agricultural purposes and food production.

Written for professionals and students in agricultural fields, the book focuses on innovative technologies for improving soil water availability, enhancing water use efficiency, and using productive irrigation systems. It also presents techniques to conserve water in the root zone as well as remote sensing techniques to assess soil water regime and predict drought on a regional scale.

Soil water management is crucial to reducing the vulnerability to agronomic drought. There are numerous examples of aquifers that have been severely depleted by misuse and mismanagement. Soil Water and Agronomic Productivity explains the factors and causes of the mismanagement of soil water and proposes options for sustainable and efficient use of scarce water resources. Meeting the global food demand will require careful worldwide management of soil and water resources, and this can only be done by sharing information and knowledge.

In recent decades, livestock producers have moved away from open grazing for a number of reasons, none having to do with the health of consumers. Genetic Resources, Chromosome Engineering, and Crop Improvement: Forage Crops demonstrates how state-of-the-art technology can encourage the raising of livestock in open pastures where they can be fed grasses grown in nature rather than meals enriched with hormones and other by-products. The volume brings together the world's leading innovators in crop science who furnish information on the availability of germplasm resources that breeders can exploit for the improvement of major forage crop varieties including alfalfa, wheatgrass and wildrye grasses, Bahiagrass, birdsfoot trefoil, clover, Bermudagrass, and ryegrass. An introductory chapter outlines the cytogenetic architecture of forage crops, describes the principles and strategies of cytogenetic and breeding manipulations, and summarizes landmark research. Ensuing chapters provide a comprehensive account of each crop: its origin; wild relatives; exploitation of genetic resources in the primary, secondary, and tertiary, and, where feasible, quarternary gene pools through breeding and cytogenetic manipulation; and genetic enrichment using the tools of molecular genetics and biotechnology. . Certain to become the standard reference, this volume- Discusses taxonomy, genomic and chromosomal constitution, and the geographical distribution Stresses the role of germplasm exploration, maintenance, and assimilation for increasing yield Presents practical improvement methodologies including conventional, cytogenetic, mutation, molecular, cell and tissue cultures, and genetic transformation In addition to serving as fodder, forage crops provide ground cover, aid in abetting erosions, yield a number of pharmaceuti

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.

Seeds are nature's consummate survivors. The next time you admire a field of waving green grassland or a stunning grove of acacia, stop to consider how it got that way--often against incredible odds. Seeds can survive freezing temperatures and drought. They can pass through our digestive systems without damage and weather a trip across the ocean, hitching a ride on marine debris. They can even endure complete desiccation, a feat taken to extraordinary lengths by the date palm, a seed from which was recovered from the palace of Herod the Great was germinated after some two thousand years. The Book of Seeds takes readers through six hundred of the world's seed species, revealing their extraordinary beauty and rich diversity. Each page pairs a beautifully composed photo of a seed--life-size, and, in some cases, enlarged to display fine detail--with a short description, a map showing distribution, and information on conservation status. The whole spectrum of seeds is covered here. There are prolific species like corn and less widely distributed species, like the brilliant blue seeds of the traveler's palm or the bird of paradise flower, aptly named for its distinctive orange coiffure. There are tiny seeds and seeds weighing up to forty pounds. And while seeds in all their shapes, sizes, and colors grant us sustenance, there are even some we would be wise to treat with caution, such as the rosary pea, whose seeds are considered more toxic than ricin. The essential guide to these complex plant creations, The Book of Seeds offers readers a rare, up-close look that will inspire scientists and nature lovers alike.

The fourth section of the book discusses secondary macronutrients and micronutrients including: calcium, iron, zinc, boron, manganese and molybdenum as well as soil organic matter. 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.

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.

This collection summarises key advances in crop modelling, with a focus on developing the next generation of crop and whole-farm models to improve decision making and support for farmers.

Building on topics previously discussed in Part 1, Part 2 addresses the challenges of combining modular sub-systems into whole farm system, landscape and regional models. Chapters cover topics such as integration of rotations and livestock, as well as landscape models such as agroecological zone (AEZ) models. Chapters also review the performance of specific models such as APSIM and DSSAT and the challenges of developing decision support systems (DSS) linked with such models. The final part of the book reviews wider issues in improving model reliability such as data sharing and the supply of real-time data, as well as crop model inter-comparison. With its distinguished editor and range of experienced and expert chapter authors, this collection will be a standard reference for crop modellers and developers of decision support systems to improve the efficiency and sustainability of farming.
