Agricultural Statistics: A Handbook for Developing Countries presents the development of agricultural statistics in various countries of Africa and Asia. This book provides a guideline to those in charge of agricultural statistics in developing countries to know their priorities and to have clear objectives. Organized into 14 chapters, this book begins with an overview of the importance of regular collection of agricultural statistics to the functioning of the community as well as for its agriculture and agricultural development. This text then examines the improvement of methods of collection of existing statistics for greater dependability. Other chapters consider the yield rates and areas of crop production. This book discusses as well the direct estimation of production, which consists of large estates with their processing plants meant for processing their products only. The final chapter deals with the various organizational set-ups for the compilation of agricultural statistics. This book is a valuable resource for agriculturists and statisticians.

An Introduction to Field Quantization is an introductory discussion of field quantization and problems closely related to it. Field quantization establishes a commutation relation of the field and finds an operator in such a manner that the Heisenberg equation of motion is satisfied. This book contains eight chapters and begins with a review of the quantization of the Schroedinger field and the close relation between quantized field theory and the many-body theory in quantum mechanics. These topics are followed by discussions of the quantization of the radiation field and the field of lattice vibrations in a solid. The succeeding chapter deals with the familiar linear equations in relativistic field theory and the deduction of certain spin independent theories, which these fields have in common. Other chapter explores the derivation technique of the conservation laws for fields with arbitrary spin directly from the field equations without explicit recourse to Noether's theorem using a configuration space version of the generalized Ward identity. The discussion then shifts to the relativistic quantization method applicable to any field with arbitrary spin; the transformation of various fields under the Lorentz transformation; and a general method for constructing wave functions explicitly, as well as the application of this method to several examples. The concluding chapter focuses on the quantization of interacting fields. This book will prove useful to physicists and researchers.

Insect Pathology is designed for a broad spectrum of readers. Is should be useful to students, lecturers, and researchers requiring information about the principles in insect pathology and the biology of pathogens. It should serve as a resource for specialists to learn about other insect pathogen systems, for generalists to become aware of advances in insect pathology, and for scientists and students, beginning or otherwise, interested in learning about insect pathology.. This book was originally intended to update the 1949 test by E. A. Steinhaus entitled Principles of Insect Pathology. The purpose for this book was twofold: To serve (1) as a text for an insect pathology and/or biological control class and (2) as a comprehensive reference source. Because this book summarizes much of the available information, its usefulness as a textbook for an insect pathology class is apparent. Although the literature citations are extensive, they are far from complete. The literature in insect pathology is voluminous and for the past decade has been expanding at an almost exponential rate. A complete review of the literature is beyond the scope of the book, and an omission of a reference does not preclude its importance. Our citations, however, should serve as a good starting point for those who wish to obtain further information. We have attempted to cover equally all subdisciplines, but shortcomings are unavoidable. For these, we take full responsibility.

The Role of Water in Agriculture focuses on the role of water in British agriculture. This book discusses the growing importance of hydrological science and agricultural hydrology. Organized into 14 chapters, this book begins with an overview of the problems of accurate rainfall measurement and its importance to agriculture. This text then presents a comprehensive study of the sources of error in agricultural water budgets. Other chapters consider the progress reports on two catchment studies and a report on the effect of agricultural treatments on water availability in the soil. This book discusses as well the sediment yields from forested and agricultural lands on an international basis. The final chapter deals with a summary of the discussions with conclusions and implications. This book is a valuable resource for hydrologists, geographers, meteorologists, agricultural scientists, applied biologists, plant physiologists, and pedologists. Engineers, administrators, and advisers will also find this book useful.
