It is difficult to forecast the serious consequences of damage to soil health on plants, animals and human beings. Agricultural soils across the globe are affected by erosion, degradation, nutrient depletion, pollution, organic matter decline and faulty management practices. This has resulted into 'Plant nutrient disorders' due primarily to imbalances, interactions, deficiencies or toxicities of one or more plant nutrients. Quality of irrigation water and environmental stress has a profound influence on this process. The present book provides an insight into the reasons for occurrence of such nutrient disorders, methodologies to monitor soil, plant, water and environment and ways to diagnose the problem through analytical and instrumental techniques. Widespread occurrence of secondary and micronutrient deficiencies in soils have resulted into low uptake of these nutrient ions by plants with adverse impact on human and animal health. Continuous cropping without due care of efficient soil and water use, have resulted in poor crop performances with low yields in many areas. This book attempts to provide answers to some pertinent questions on the subject i.e. I. Why plant nutrient disorders occur? II. Whether these are site or crop specific? III. How best one can diagnose the problem, by adopting sound analytical techniques? IV. What are the major concerns? V. How best one can manage such disorders to sustain soil health for crop production? Implementing scientific soil management programme requires good team work among scientists, extension workers & field staff with governmental support and farmer's participation. It is hoped that this book written in a simple language will be very useful for the students and teachers of Agriculture, Horticulture, Forestry, Fisheries & allied disciplines.

Plants constitute an excellent ecosystem for microorganisms. The environmental conditions differ considerably between the highly variable aerial plant part and the more stable root system. Microbes interact with plant tissues and cells with different degrees of dependence. The most interesting from the microbial ecology point of view, however, are specific interactions developed by plant-beneficial (either non symbiotic or symbiotic) and pathogenic microorganisms. Beneficial interactions are caused by symbiotic and non-symbiotic bacteria and a highly specialized type of fungi, the mycorrhizae. The pathogenic and detrimental interactions of microbes involve viroids, viruses, bacteria and fungi, and lead to infectious diseases affecting only the plant kingdom. Microflora composition of any agro-ecosystem is governed by the equilibrium created by the associations and interactions of all flora and fauna found in the community. In soil, microorganisms live in close proximity and interact among themselves as well as with existing plant communities in different ways, which could be beneficial (mutualism, commensalism, proto-cooperation) or neutral (epiphytic). These microbial interactions govern the functioning and stability of agro-ecosystem, playing significant role in the production and productivity crops. Hence, this book on Plant-Microbe Interactions is aimed at bringing out the recent developments in this field including the molecular mechanisms and proteomics involved in the establishment of Plant-Microbe Interactions. The book reviews the enormous diversity of plant associated microbes, and their molecular mechanisms, small molecules and proteomics involved in the establishment of their mutual interactions. Utilization of these rhizosperic, phyllospheric and endophytic microbes as nutrient providers, in combating phytopathogens and ameliorating the stressed and polluted soils is also explained. Importantly, the book also throws light on the unanswered questions and future direction of research in the field. It illustrates how the basic knowledge can be amalgamated with advanced technology to design the future bio-formulations. This book will be useful in providing latest information in this topic to Scientists, Researchers, Ph.D and PG students working in the field of Plant Sciences.

The Farm Labor Problem: A Global Perspective explores the unique character of agricultural labor markets and the implications for food production, farm worker welfare and advocacy, and immigration policy. Agricultural labor markets differ from other labor markets in fundamental ways related to seasonality and uncertainty, and they evolve differently than other labor markets as economies develop. We weave economic analysis with the history of agricultural labor markets using data and real-world events. The farm labor history of California and the United States is particularly rich, so it plays a central role in the book, but the book has a global perspective ensuring its relevance to Europe and high-income Asian countries. The chapters in this book provide readers with the basics for understanding how farm labor markets work (labor in agricultural household models, farm labor supply and demand, spatial market equilibria); farm labor and immigration policy; farm labor organizing; farm employment and rural poverty; unionization and the United Farm Workers movement; the Fair Food Program as a new approach to collective bargaining; the declining immigrant farm labor supply; and what economic development in relatively low-income countries portends for the future of agriculture in the United States and other high-income countries. The book concludes with a chapter called "Robots in the Fields," which extrapolates current trends to a perhaps not-so-distant future. The Farm Labor Problem serves as both a guide to policy makers, farmworker advocates and international development organizations and as a textbook for students of agricultural economics and economics.

The basic aim of this manual is to provide useful resource materials for training young students and faculties working in the area of plant systematics. The manual provides updated information on basic as well as applied aspects of plant systematics on various groups of plants like Algae, Lichens, Bryophytes, Pteridophytes, Gymnosperms and Angiosperms. 1 to 3 describe the various approaches and methods to study microbial and fungal diversity, which is basically a very useful precursor to the students and young researchers. 4 and 5 provide deals with the multi-dimensional approaches in Lichen systematics. The book progresses upwards through the plethora of information on the diversity and systematics of Algae, Bryophytes, Pteridophytes and Gymnosperms ( 6-10). 11 to 15 contain on the plant methodological details identification, approaches and methods of Flora, revision, monograph and development of herbarium. This information is very important for the students and young faculties who intend to pursue their researches in plant taxonomy. 14 and 15 particularly provide all the relevant information on the International Code of Plant nomenclature including cultivated plants. These s per se are very significant for the amateur as well as serious readers of plant taxonomy. Plant taxonomy and biosystematics is a dynamic subject, as it derives information from various other disciplines like palynology, seed morphology, pharmacognosy, molecular biology, etc. We have, therefore, broaden the scope of this book by including the s on palynology, seed morphology, molecular systematics, biostatistics, ecological and remote sensing methods for diversity analyses, and pharmacognostical tools for identification of herbal drugs ( 16-22). The knowledge and information on these applied aspects of biology in relation to taxonomy will certainly infuse the interest in readers, who are pursuing plant taxonomy as their scientific pursuits. 23 and 24 describe the various methods of characterization and evaluation of ornamental and medicinal plants. The last (25) of the book provides the information about CSIR-NBRI Botanic Garden and its various repositories, which could be of great interest to the readers from the perspectives of plant conservation.
