In any ecosystem, plant and microbe interaction is inevitable. They not only co-exist but also support each other's survival and also provide for sustenance in stressful environment. Agro-ecosystems of many regions around the globe are affected by multi-stress. Major limiting factors affecting the agricultural productivity worldwide are environmental stresses. Apart from decreasing yield they introduce devastating impact on plant growth as well. Plants battle with various kind of stresses with the help of symbiotic association with the microbes in the rhizosphere. Naturally existing plant-microbe interaction facilitates survival of plants under these stressful conditions. Rhizosphere consists of many groups of microbes, plant growth-promoting bacteria (PGPB) is one such group of microbes which assist plants in coping with multiple stresses and in plant growth as well. These microbes help in stress physiology of the plants and can be extremely useful in solving agricultural as well food security problems. The proposed book is split into two parts, with an aim to provide comprehensive description and highlight a holistic approach. It elucidates various mechanisms in rhizosphere of nutrient management, stress tolerance and enhanced crop productivity. The book discusses rhizospheric flora and its importance in enhancement of plant growth, nutrient content, yield of various crops and vegetables as well as soil fertility and health. Both volumes of the book addresses fundamentals, applications as well as research trends and new prospects of agricultural sustainability. Volume 2: Nutrient Management and Crop Improvement, contains chapters which cover a broad overview of plant growth promoting activities of microbes. This proposed book also highlights the contribution of nitrogen, phosphorus, potassium, iron and zinc-solubilizing microbes from rhizospheric soil to develop efficient indigenous microbial consortia to enhance the food and nutritional security. With the given content and layout the proposed book will be an all-inclusive collection of information, which will be useful for students, academicians, researchers working in the field of rhizospheric mechanisms, agricultural microbiology, soil microbiology, biotechnology, agronomy and sustainable agriculture and also for policy makers in the area of food security and sustainable agriculture. It will be of special interest to both academics and professionals working in the fields of microbiology, soil microbiology, biotechnology and agronomy, as well as the plant protection sciences. Timely, this edited and research book provides an essential and comprehensive source of material from basic to advance findings on microbes and their role in agricultural and soil sustainability.

Despite a gradual and sustained decline in the contribution of agriculture to the economies of the member countries of the Organization for Economic Cooperation and Development (OECD), the sector remains socially and politically important. Although agriculture accounts for less than 2% of the gross domestic product of the OECD countries, it occupies over 35% of their total land area. Predominantly rural regions, where agriculture remains particularly important, contain almost one quarter of the population of OECD countries. The past quarter century has witnessed signi?cant changes in agricultural po- cies in OECD countries. Although total support remains high, a shift has taken place from price-linked measures to direct income support, most notably in the European Union. Policies have been adapted to meet pressing social concerns, such as ens- ing food security and improving environmental quality. OECD countries face major economic issues due to the ageing of their populations and the need to adapt to gl- alization and increasing competition from emerging economies. Continued pressure to reform agricultural policies will be exerted by the need to economize on the use of scarce public resources. At the same time, agriculture faces new challenges g- erated by climate change, the "greening" of the economy, increasing scarcity of energy and water, and the demands placed on the food system by an expanding world population.

In an effort to implement conservation measures farmers have used a variety of production methods, including the use of reduced or zero tillage and cover crops. One benefit of these production methods has been early season weed control. The literature suggests that a variety of mechanisms may be involved, among them the allelopathic effects of phenolic acids. This retrospective analysis addresses the following: How likely are phenolic acid concentrations and environmental conditions in wheat no-till cropping systems for the inhibition of annual broadleaf weed emergence? and Do phenolic acids have a dominant role or are they just one component of a larger promoter/modifier/inhibitor complex? The book covers allelopathic plant-plant interactions, laboratory and field experiments, and future research. It uses a journal format, provides justifications for procedures used, if-then hypotheses, and cons and pros so that readers can reach their own conclusions.

This volume contains a solid body of the current state of knowledge on the various themes and activities in agroforestry worldwide. It is organized into three sections: the Introduction section consists of the summaries of six keynote speeches at the 2nd World Congress of Agroforestry held in Nairobi, Kenya, in 2009; that is followed by two sections of peer-reviewed thematic chapters grouped as "Global Perspectives" (seven chapters) and "Regional Perspectives" (eleven chapters), authored by professional leaders in their respective agroforestry-related fields worldwide. A total of 130 professionals from institutions in 33 countries in both developing and the industrialized temperate regions of the world contributed to the book as chapter authors and/or reviewers. Thus, the book presents a comprehensive and authoritative account of the global picture of agroforestry today.

Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock.

In this book, Henry Le Houerou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined."

From the first vague idea to use Konrad Hagedorn's 60th birthday as an inspi- tion for taking stock of his vibrant academic contributions, this joint book project has been a great pleasure for us in many ways. Pursuing Hagedorn's intellectual development, we have tried to reflect on the core questions of humanity according to Ernst Bloch "Who are we?," "Where do we come from?" and "Where are we heading?" In this way, and without knowing it, Konrad Hagedorn initiated a c- lective action process he would have very much enjoyed ... if he had been allowed to take part in it. But it was our aim and constant motivation to surprise him with this collection of essays in his honour. Konrad Hagedorn was reared as the youngest child of a peasant family on a small farm in the remote moorland of East Frisia, Germany. During his childhood in the poverty-ridden years after the Second World War, he faced a life where humans were heavily dependent on using nature around them for their livelihoods; meanwhile, he learned about the fragility of the environment. As a boy, he - tended a one-room schoolhouse, where his great intellectual talents were first r- ognised and used for co-teaching his schoolmates. These early teaching expe- ences might have laid the foundations for his later becoming a dedicated lecturer and mentor.

Plants possess a range of potential cellular mechanisms that may be involved in the detoxification of heavy metals and thus tolerance to metal stress. Metal toxicity causes multiple direct and indirect effects in plants that concern practically all physiological functions. The main purpose of this book is to present comprehensive and concise information on recent advances in the field of metal transport and how genetic diversity affects heavy metal transport in plants. Other key futures of the book are related to metal toxicity and detoxification mechanisms, biochemical tools for HM remediation processes, molecular mechanisms for HM detoxification, how metallomics and metalloproteomics are affected by heavy metal stress in plants, and the role of ROS metabolism in the alleviation of heavy metals. Some chapters also focus on recent developments in the field of phytoremediation. Overall the book presents in-depth information and the most essential advances in the field of heavy metal toxicity in plants in recent years.

A monumental 1176 page treatise on every aspect of Farm Crops and Farm Livestock in the Edwardian period, this most complete work of its kind, is a mine of information. The livestock section discusses numerous breeds of horses (including ponies and donkeys) cattle, sheep, goats and poultry; the history, characteristics, care, breeding, and showing of each individual breed, as well as a more general discussion of animal husbandry, live stock ailments and remedies, farm pests, and of course animal products-meat, dairy, wool, honey, etc.. Sheepdogs are not overlooked. The farm crop section covers all British grains, beans and peas, potatoes, hops, flax, turnips, forage crops (for cattle) in similar detail, as well as "subsidiary crops" (that is, vegetables I modern usage). As well as the material specifically on crops and livestock, there is considerable background information, including a summary of the seasons and seasonal tasks, a detailed analysis of the then recent experiments in manuring and composting at Rothamstead that continue to this day, and a discussion of the impact of non-farm animals (badgers, mice, owls ...) on the farm.In addition to sixty eight full page plates there are numerous illustrations in the text, and a complete index.

The book details the innovative TERM (The Enormous Regional Model) approach to regional and national economic modeling, and explains the conversion from a comparative-static to a dynamic model. It moves on to an adaptation of TERM to water policy, including the additional theoretical and database requirements of the dynamic TERM-H2O model. In particular, it examines the contrasting economic impacts of water buyback policy and recurring droughts in the Murray-Darling Basin. South-east Queensland, where climate uncertainty has been borne out by record-breaking drought and the worst floods in living memory, provides a chapter-length case study. The exploration of the policy background and implications of TERM's dynamic modeling will provide food for thought in policy making circles worldwide, where there is a pressing need for solutions to similarly intractable problems in water management.

The book examines the status of public service in developing countries, in the sectors of health, infrastructure, labour and marginalized populations, rural economy and public administration. The last decade has witnessed significant government focus on service delivery in developing nations like South Africa, Philippines, India and Malaysia. At the forefront of this movement has been the public sector reforms significantly driven by two broad factors: public sector inefficiencies and liberal economic ideology. This move towards efficient public service delivery in developing nations (versus developed nations) has required a significant shift in institutional thinking and institutional capacity for the governments. It is therefore no surprise that while economic liberalization has been relatively easy to implement, governance reforms towards public service delivery has been significantly more challenging. In this background, the chapters of the book, with sector themes, examine the three basic foundations of public policy-courses of action, regulatory measures and issues, and funding structures and priorities-in public service delivery. The book is a multi country, multi sector, perspective since it includes studies from Russian Federation, India, Ethiopia, Pakistan, Fiji, South Africa, Columbia, Philippines, Macedonia and India. This perspective lends itself to the investigation for a comprehensive overall development model.

This book uses an economic framework to examine the consequences of U.S. farm and food policies for obesity, its social costs, and the implications for government policy. Drawing on evidence from economics, public health, nutrition, and medicine, the authors evaluate past and potential future roles of policies such as farm subsidies, public agricultural R&D, food assistance programs, taxes on particular foods (such as sodas) or nutrients (such as fat), food labeling laws, and advertising controls. The findings are mostly negative-it is generally not economic to use farm and food policies as obesity policy-but some food policies that combine incentives and information have potential to make a worthwhile impact. This book is accessible to advanced undergraduate and graduate students across the sciences and social sciences, as well as to decision-makers in the public, private, and not-for-profit sectors.

Software Engineering Techniques Applied to Agricultural Systems presents cutting-edge software engineering techniques for designing and implementing better agricultural software systems based on the object-oriented paradigm and the Unified Modeling Language (UML). The focus is on the presentation of rigorous step-by-step approaches for modeling flexible agricultural and environmental systems, starting with a conceptual diagram representing elements of the system and their relationships. Furthermore, diagrams such as sequential and collaboration diagrams are used to explain the dynamic and static aspects of the software system. This second edition includes: a new chapter on Object Constraint Language (OCL), a new section dedicated to the Model-VIEW-Controller (MVC) design pattern, new chapters presenting details of two MDA-based tools - the Virtual Enterprise and Olivia Nova and a new chapter with exercises on conceptual modeling. It may be highly useful to undergraduate and graduate students as the first edition has proven to be a useful supplementary textbook for courses in mathematical programming in agriculture, ecology, information technology, agricultural operations research methods, agronomy and soil science and applied mathematical modeling. The book has broad appeal for anyone involved in software development projects in agriculture and to researchers in general who are interested in modeling complex systems. From the reviews of the first edition: "The book will be useful for those interested in gaining a quick understanding of current software development techniques and how they are applied in practice... this is a good introductory text on the application of OOAD, UML and design patters to the creation of agricultural systems. It is technically sound and well written." -Computing Reviews, September 2006

Drawing on concrete real-world examples, the book provides readers with an essential overview of adaptation, from research to system development to practices, taking agriculture in Asia as the example. As such, it offers a valuable asset for all researchers and policymakers whose work involves adaptation planning, climate negotiations, and/or agricultural developments.

The TransForum Model: Transforming Agro-innovation Toward Sustainable Development presents new insights on how to use innovation for the complex challenge of sustainable development. Innovation has been at the heart of the positive agricultural developments in both production and productivity growth during the last decades. Due to the negative impact of these developments on the physical and social environment, a transformational change of the agricultural sector is needed to shift toward a more sustainable development. Changing the agro innovation system is necessary to bring this about. In this book, six years of experimenting with sustainable development in agriculture is translated into a set of principles and guidelines. Together these constitute The TransForum Model to deal with innovation and sustainable development. This book shows how different scientific disciplines contribute to this new mode of agro innovation.

The interactions between the plant, soil and microbes are complex in nature. Events may be antagonistic, mutualistic or synergistic, depending upon the types of microorganisms and their association with the plant and soil in question. Multi-trophic tactics can therefore be employed to nourish plants in various habitats and growth conditions. Understanding the mechanisms of these interactions is thus highly desired in order to utilize the knowledge in an ecofriendly and sustainable way. This holistic approach to crop improvement may not only resolve the upcoming food security issues, but also make the environment greener by reducing the chemical inputs. Plant, soil and microbe, Volume 1: Implications in Crop Science, along with the forthcoming Volume 2: Mechanisms and Molecular Interactions, provide detailed accounts of the exquisite and delicate balance between the three critical components of agronomy. Specifically, these two titles focus on the basis of nutrient exchange between the microorganisms and the host plants, the mechanism of disease protection and the recent molecular details emerged from studying this multi-tropic interaction. Together they aim to provide a solid foundation for the students, teachers, and researchers interested in soil microbiology, plant pathology, ecology and agronomy.

This book performs a SWOT (strengths, weaknesses, opportunities and threats) analysis to examine the current food crisis and how it relates to the use of crops for energy. It analyses how energy crops may help solve humankind's environmental changes and summarises the economic and practical changes of cultivating and utilising energy crops. Two of humanity's greatest challenges are the need for more food production as well as growing demands for energy. Biofuel cultivation has been identified as a solution to growing energy use, and biomass power plants offer a rare renewable energy source that requires only basic technology. In this context, a dilemma arises concerning whether energy crops should be used for energy or to help remedy the food crisis. SWOT analysis allows us to organise and weigh different pros and cons against each other in terms of economics, job creation, environmental impacts, the climate change agenda, and European Union (EU) directives that promote biofuels over fossil fuels. By pursuing this approach, the book helps researchers and decision-makers cut through the many competing arguments in connection with this complex subject.

Plant growth is of great economical and intellectual interest. Plants are the basis of our living environment, the production of our food and a myriad of plant-based natural products. Plant bio-mass is also becoming an important renewable energy resource.

Agricultural plant cultivation and breeding programs have altered plant productivity and yield parameters extensively, yet the principles and underlying mechanisms are not well understood. At the cellular level, growth is the result of only two processes, cell division and cell expansion, but these two processes are controlled by intertwined signaling cascades and regulatory mechanisms forming complex regulatory networks. Ultimately this network is what plant scientists are trying to unravel.

The sequencing of model and agronomically important plant genomes allows complete insight into the molecular components involved in each process. Methods to quantify the molecular changes, image growth processes and reconstruct growth regulatory networks are rapidly developing. This knowledge should help to elucidate key regulators and to design methods to engineer plant architecture and growth parameters for future human needs. This volume gives a comprehensive overview of what is known about plant growth regulation and growth restraints due to environmental conditions and should allow readers at all levels an entry into this exiting field of research.

This book examines how crop diversification strategies can help to ensure sustainable agricultural development across different land-size categories, with a focus on Malda District in West Bengal, India. Using Malda as the study area, a region with nearly 4 million people, the book assesses the extent, pattern, factors and future of crop diversification and its contribution to the development of agriculture in Malda and in India as a whole. The work presents data from 1995-2015 concerning changing cropping patterns at various land-size distributions, and analyzes the information over the twenty year period to understand the link between crop diversification and agricultural development, in order to combat major agricultural issues and make suitable policy recommendations at micro (rural) and macro (urban) levels of agricultural planning. The study is a unique contribution to the field of agricultural geography, and will be of use to students and researchers, as well as government organizations, city/community planners and agriculture managers.

The Handbook identifies all aspects of Regulatory Plant Biosecurity and discusses them from the standpoint of preventing the international movement of plant pests, diseases and weeds that negatively impact production agriculture, natural plant-resources and agricultural commerce.

Soils into which crop plants root and from which they obtain essential minerals and water contain huge arrays of microbes. Many have highly beneficial effects on crop growth and productivity, others are pathogens causing diseases and losses to yield and quality, a few microbes offer protection from these pathogenic forms and others have little or no effect. These intimate and often complex inter-relationships are being explored with increasing success providing exciting opportunities for increasing crop yields and quality in sustainable harmony with the populations of beneficial soil microbes and to the detriment of pathogens. This book explores current knowledge for each of these aspects of soil microbiology and indicates where future progress is most likely to aid in increasing crop productivity by means which are environmentally benign and beneficial.

This book discusses the role of salt in current agricultural approaches, including the low salt tolerance of agricultural crops and trees, impact of saline soils, and salt-resistant plants. Halophytes are extremely salt tolerant plants, which are able to grow and survive under salt at concentrations as high as 5 g/l by maintaining negative water potential. The salt-tolerant microbes inhabiting the rhizospheres of halophytes may contribute to their salt tolerance, and the rhizospheres of halophytic plants provide an ideal opportunity for isolating various groups of salt-tolerant microbes that could enhance the growth of different crops under salinity stress. The book offers an overview of salt-tolerant microbes' ability to increase plant tolerance to salt to facilitate plant growth, the potential of the halophytes' rhizospheres as a reservoir of beneficial salt-tolerant microbes, their future application as bio-inoculants in agriculture and a valuable resource for an alternative way of improving crop tolerance to salinity and promoting saline soil-based agriculture. This special collection of reviews highlights some of the recent advances in applied aspects of plant (halophytes)-microbe interactions and their contribution towards eco-friendly approaches saline soil-based agriculture.
