The third edition of this book exposes the reader to a wide array of engineering principles and their application to agriculture. It presents an array of more or less independent topics to facilitate daily assessments or quizzes, and aims to enhance the students' problem solving ability. Each chapter contains objectives, worked examples and sample problems are included at the end of each chapter. This book was first published in the late 60's by AVI. It remains relevant for post secondary classes in Agricultural Engineering Technology and Agricultural Mechanics, and secondary agriculture teachers.
This book is for use in introductory courses in colleges of agriculture and in other applications requiring a problematic approach to agriculture. It is intended as a replacement for an Introduction to Agricultural Engineering by Roth, Crow, and Mahoney. Parts of the previous book have been revised and included, but some sections have been removed and new ones has been expanded to include a chapter added. Problem solving on techniques, and suggestions are incorporated throughout the example problems. The topics and treatment were selected for three reasons: (1) to acquaint students with a wide range of applications of engineering principles to agriculture, (2) to present a selection of independent but related, topics, and (3) to develop and enhance the problem solving ability of the students. Each chapter contains educational objectives, introductory material, example problems (where appropriate), and sample problems, with answers, that can be used for self-assessment. Most chapters are self-contained and can be used independently of the others. Those that are sequential are organiZed in a logical order to ensure that the knowledge and skills needed are presented in a previous chapter. As principal author I wish to express my gratitude to Dr. Lawrence O. Roth for his contributions of subject matter and gUidance. I also wish to thank Professor Earl E. Baugher for his expertise as technical editor, and my wife Marsha for her help and patience. HARRY FIELD v 1 Problem Solving OBJECTIVES 1. Be able to define problem solving.
Agricultural engineering principles and practices is an exposition on a previous work titled; fundamental principles of agricultural engineering practice published by same author in 2007 which only explored aspects of principles of agricultural engineering with less emphasis on production practices engaged in at every level of agricultural operations. Thus the book gave a narrowed outlook of agricultural engineering fundamentals, which is not adequate for providing relevant information in practice with agricultural engineering background undertaking at all levels of engineering training in the university, polytechnic and colleges. Hence, the book has been enlarged in scopes and packaged in 2 volume titles (11 chapters in Volume I and 9 chapters in Volume II). Volume (I) has three parts that addresses fundamental aspects of agricultural engineering: Part 1 has six chapters comprising of agricultural engineering development, issues on agricultural mechanization, management of engineering utilities, economics of machine use, farm power and agricultural machinery and development. Part 2, in 3 chapters, addresses all aspects of site surveying, land clearing undertakings and landform development, various agricultural practices, and tillage operations. Part 3 has 2 chapters on crop planting operations and establishment practices. Various planting patterns and characteristics, equipment types and planter component descriptions are features x-rayed in this section. Chapters 10 and 11 dwells much on post planting operations involving crop thinning, fertilizer application, pest and weed control programme, and new development in chemical and fertilizer application as well as integrated pest control management. The scope of agricultural practice is inexhaustible and that informs a continual development and expansion of knowledge as advancements takes place.
Agricultural and Horticultural Engineering: Principles, Models, Systems, and Techniques focuses on the developments in agriculture and horticulture, including the role of engineers in employing measures in the management of plants, animals, and machinery. The book first offers information on the process of surveying, including tape, compass, and aerial surveying, leveling, barometric leveling with the aneroid, plane tabling, and electronic distance measurement and electronic total. The text then takes a look at models of the environment, material properties, and the relationship between stress and strain. The publication examines workshop methods and hydraulics. Topics include soldering, electric arc welding, low temperature brazing, welding using oxygen-acetylene apparatus, hydrodynamics, and water supply requirements. The text also reviews electricity and electronics and power and thermal systems, as well as alternating voltage supplies, electrical motors, electrical safety, power and energy consumption, and the fundamental principles of electronics. The manuscript is a dependable reference for engineers and readers interested in agricultural and horticultural engineering.
Agricultural Systems, Second Edition, is a comprehensive text for developing sustainable farming systems. It presents a synthetic overview of the emerging area of agroecology applications to transforming farming systems and supporting rural innovation, with particular emphasis on how research can be harnessed for sustainable agriculture. The inclusion of research theory and examples using the principles of cropping system design allows students to gain a unique understanding of the technical, biological, ecological, economic and sociological aspects of farming systems science for rural livelihoods. This book explores topics such as: re-inventing farming systems; principles and practice of agroecology; agricultural change and low-input technology; ecologically-based nutrient management; participatory breeding for developing improved and relevant crops; participatory livestock research for development; gender and agrarian inequality at the local scale; the nature of agricultural innovation; and outreach to support rural innovation. The extensive coverage of subjects is complemented with integrated references and a companion website, making this book essential reading for courses in international agricultural systems and management, sustainable agricultural management, and cropping systems. This book will be a valuable resource for students of agricultural science, environmental engineering, and rural planning; researchers and scientists in agricultural development agencies; and practitioners of agricultural development in government extension programs, development agencies, and NGOs. - Provides students with an enhanced understanding of how research can be harnessed for sustainable agriculture - Incorporates social, biological, chemical, and geographical aspects important to agroecology - Addresses social and development issues related to farming systems
In the branch of Agricultural Engineering, especially in Farm Machinery and Power sector, there is a need for a book exclusively dealing with various concepts and their applications in transparent and clear manner. So, an effort has been made to prepare this book entitled "Concepts of Farm Machinery and Power" to meet the demand of students, teachers, RS. The book will be useful immensely to the students preparing for GATE examination in AG papers and also for JRF, ARS, IFS examinations. The chapters of the book deals with conceptual analysis of farm machineries, which are confusing and difficult to understand. It is expected that the theoretical as well as numerical analysis of this book will sharpenthe ingenious power of the readers and help them to solve problemsquickly. Moreover, many problems are solved in different ways, which will help the readers in understanding and applying the concepts properly. I am extremely grateful to my teachers Dr. Subrata Karmakar, Associate Professor, Dept. of Farm Machinery and Power, Bidhan Chandra Krishi Viswavidyalaya; Prof. Partha Sarathi Chattopadhaya, Professor, Dept. of Farm Machinery and Power, Bidhan Chandra Krishi Viswavidyalaya; Er. Ravi Reddy, Senior Technician, CFMTTI, Budni, M.P., and my B. Tech friends for their encouragement and kind cooperation. Sagacious suggestions and discrete criticism are welcome to improve the book further, so that it becomes more relevant and more beneficial to the readers in real terms. Finally, I envisage this attempt as an important step in removing hurdles in the path of popularization of Agricultural Engineering. I hope that it will fire imaginations and ability of many Agricultural Engineers in the profession to produce such innovative works in future. “Agricultural Engineering— galvanizing agriculture”.
