Book Description
The updated edition of the classic, fundamental book on weed science Weed Science provides a detailed examination of the principles of integrated weed management with important details on how chemical herbicides work and should be used. This revised Fourth Edition addresses recent developments affecting weed science. These include the increased use of conservation-tillage systems, environmental concerns about the runoff of agrochemicals, soil conservation, crop biotechnology, resistance of weeds and crops to herbicides, weed control in nonagricultural settings and concerns regarding invasive plants, wetland restoration, and the need for a vastly improved understanding of weed ecology. Current management practices are covered along with guidance for selecting herbicides and using them effectively. To serve as a more efficient reference, herbicides are cross-listed by chemical and brand name and grouped by mechanism of action and physiological effect rather than chemical structure. In addition, an introduction to organic chemistry has been added to familiarize readers with organic herbicides. Also included are guidelines on weed-control practices for specific crops or situations, such as small grains, row crops, horticultural crops, lawns and turf, range land, brush, and aquatic plant life. Generously supplemented with 300 drawings, photographs, and tables, Weed Science is an essential book for students taking an introductory course in weed science, as well as a reference for agricultural advisors, county agents, extension specialists, and professionals throughout the agrochemical industry.

Book Description
This manual is primarily for agriculture students and follows the curriculum suggested by the 5th Deans' Committee and approved by the ICAR. The manual will provide the students with the practical information they need to know about weed management. The chapters of this manual have been chosen and put together in a way that will improve students practical learning about weed management, with the help of images, tables, and figures. The manual is primarily intended for agriculture students and this manual will cater the need of the student about practical knowledge on weed management. Agriculture students at both the undergraduate and postgraduate levels have felt for a long time that they need more detailed information on practical application of weed management. The information on the subject is presented in a way and order that makes it easier for students, researchers, and policymakers to understand and follow their approaches and the problems with weed management practices.

Book Description
It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed science's development. - The first analytical history of weed science to be written - Compares the development of weed science, entomology and plant pathology - Identifies the primary founders of weed science and describes their role

Book Description
Agronomy deals with the science and technology of producing and using plants for food, fuel, fiber, and land reclamation. The importance of agronomy provides farmers with agricultural information about how to grow and care for plants and soils in certain environments. Factors such as climate, roots, moisture, weeds, pests, fungi, and erosion can pose significant challenges when farmers attempt to produce a plentiful harvest. In order to discover ways of integrating crops into the environment in ways that will allow them to prosper, agronomists study these agricultural hurdles. Throughout history, scientific and technological advances have greatly impacted the agriculture industry. Early farmers improved their crop production by inventing the first hoes. Today, farmers improve crop production through the use of global positioning systems (GPS). How did these changes happen? How did people learn about new ideas? How have these ideas changed farming methods? In recent times, research and development in this area have made innovations in farming products and practices.Fundamentals Of Agronomy presents the comprehensive coverage in the pursuit of improving the yield of crops, protecting crops against diseases and pest, making livestock healthy all the time, designing the best method of crops storage and even helping in predicting the climate conducive for agricultural practice cannot be over emphasized. Crop protection is very vital in agriculture. Disease affects plants and leads to delay in metabolic activities, stunted growth, shedding of flowers and fruits and sometimes the actual death of the plant. Cultural and chemical controls are most of the time used. Culturally, crop rotation is adopted, burning remains after harvesting, regular weeding of the soil, proper spacing of crops using of high yielding and resistant varieties and practicing of irrigation during dry season are adopted.This book will be of interest to students, professional practitioners, educators, and advisers who work directly with farmers, companies, and others in the agriculture community to implement the latest methods and tools for growing crops profitably and sustainably.
