Book Description
Discover environmentally safe ways to control weeds and pests! Until now farmers have had to choose between using expensive herbicides and fertilizers, which pollute the water table, or watching crop yields drop. All too often, crop yields dropped anyway, despite intensive farming. Allelopathy in Agroecosystems offers fresh hope. It provides an in-depth understanding of allelopathy-the mysterious, complex biochemical interactions among plants and microbes. This little-understood phenomenon plays a large role in agriculture, for good or ill. It can lead to changes in nutrient dynamics, vegetation structure, and species diversity. This comprehensive treatise is the first compendium devoted to explaining and exploring these chemical interactions in agricultural crop systems. Allelopathy in Agroecosystems explains how these interactions can make soil “sick,” especially in intensively cropped areas. This leads to less growth and lower yield. On the other hand, it has great potential as an environmentally safe method of weed and pest management. The fascinating original research presented here will help you understand the complexities of this invisible yet potent force in agriculture. Allelopathy in Agroecosystems examines this interaction as it affects the most important concerns of farmers and agronomists, including: beneficial interactions between crops weed control using crop residues crop rotation natural herbicides genetic engineering soil rhizosphere bacteria improving pastures forest/crop interactions sustainable management of agroecosystems new directions for research International in scope, Allelopathy in Agroecosystems offers an abundance of scientific data on this revolutionary new concept. It offers incalculable potential for rescuing farmed-out land, increasing crop yields, and cutting back on expensive soil additives. Every agronomist, environmental scientist, policymaker, agricultural librarian, and advocate of sustainable farming needs this book.

Book Description
Allelopathy is an ecological phenomenon by which plants release organic chemicals (allelochemicals) into the environment influencing the growth and survival of other organisms. In this book, leading scientists in the field synthesize latest developments in allelopathy research with a special emphasis on its application in sustainable agriculture. The following topics are highlighted: Ecological implications, such as the role of allelopathy during the invasion of alien plant species; regional experiences with the application of allelopathy in agricultural systems and pest management; the use of microscopy for modeling allelopathy; allelopathy and abiotic stress tolerance; host allelopathy and arbuscular mycorrhizal fungi; allelopathic interaction with plant nutrition; and the molecular mechanisms of allelopathy. This book is an invaluable source of information for scientists, teachers and advanced students in the fields of plant physiology, agriculture, ecology, environmental sciences, and molecular biology.

Book Description
Science is essentially a descriptive and experimental device. It observes nature, constructs hypotheses, plans experiments and proposes theories. The theory is never contemplated as the 'final truth', but remains ever subject to modifications, changes and rejections. The science of allelopathy in a similar way has emerged, and exists on a similar footing; our endeavour should be to keep it fresh and innovative with addition of newer in formation and concepts with the rejection of older ideas and antiquated techniques. During the past few decades encouraging results have been obtained in various aspects of allelopathic researches. However, in addition to continuing efforts in all these directions, constant attempts are to be made to describe the mechanics of allelopathic activity in molecular terms and to discover ways and means to exploit it for the welfare of mankind. We feel that multidisciplinary efforts are the only tool to achieve this goal. It is the hope of the editors that this book will serve as a document which identifies an integrated approach, through which research both to understand and exploit allelopathy can be conducted. The present volume arose out of an attempt to bring together eminent scientists in allelopathy to describe their work, of a highly diverse nature, under one title.

Book Description
Allelopathic studies may be defined in various aspects; weed against weed/crop and vice versa. This book focuses on the ways to utilize the allelopathic potential of weeds or crops for controlling weeds in the agroecosystems. Vigorous use of herbicides is poisoning our environment at an alarming rate; allelopathy can be employed as a useful alternative to control weeds naturally under field conditions. The book contains chapters on the history of allelopathy; allelopathic potential of several important crops (rice, wheat, sorghum, maize, mustard, sunflower) and weeds (members of Solanaceae, Convolvulaceae, Asteraceae, Verbenaceae). Moreover, it highlights how the allelopathic potential of these weeds and crops can be employed effectively to suppress weeds under field conditions. The book also discusses topics on the role of allelochemicals in agroecosystems; impact on local flora; biotic stress induced by allelochemicals; mechanism of action of allelochemicals and future prospective of allelopathy. Prepared with basic concepts and importance of allelopathy, this book is intended for the agricultural community, botanists, students and researchers.

Book Description
The rapidly growing human population has increased the dependence on fossil fuel-based agrochemicals, such as fertilizers and pesticides, to produce the required agricultural and forestry products. This has exerted great pressure on non-renewable fossil fuel resources, which cannot last indefinitely. Not only do agrochemicals pollute the environment, but pests also become resistant to pesticides. Thus, present agricultural practices exploit natural resources, and damage fauna and flora and agroecosystems. One safe alternative to overcome these problems is the use of allelopathy to sustain development in agriculture and forestry and maintain a clean environment for future generations. This book is the Proceedings of the III International Congress on Allelopathy in Ecological Agriculture and Forestry, held on August 18-21, 1998, at the University of Agricultural Sciences, Dharwad, Karnataka, India, and provides an updated status of current allelopathy research in various leading countries, with the overall aim of developing new technologies for ecological agriculture and forestry in the 21st century. To date, no book on ecological agriculture has discussed these aspects, hence it is the first time that such information is available. The chapter contributors are leading specialists in their fields, and all chapters have been peer-reviewed by international referees. This book will be indispensable for agricultural scientists (agronomists, entomologists, nematologists, plant pathologists, horticulturists, plant breeders, agroforesters, foresters, soil scientists), bioscientists (biochemists, organic chemists, plant ecologists, microbiologists and limnologists), environmentalists, graduate students and farmers, as well as for organizations engaged in sustainable agriculture and organic agriculture.

Book Description
Allelopathy offers great potential: (a) to increase agriculture production (food grains, vegetables, fruits, forestry), (b) to decrease harmful effects of modern agricultural practices (multiple cropping, leaching losses from N – fertilizers, indiscriminate use of pesticides viz. weedicides, fungicides, insecticides and nematicides and development of pesticides tolerant /resistant biotypes in pests) on soil health/productivity and on environment and (c) to maintain soil productivity and pollution free environment for our future generations. It is hoped that in the near future the allelopathy may be used in crop production, crop protection, agroforestry and agro-horticultural systems of developed countries. Therefore, it may be one of the strategies to increase agricultural production in Sustainable Agriculture of 21st century. This book is based on the research findings and addresses to various intricate problems of crop production, to which there was no definite answer in the past but now have been attributed to allelopathy.

Book Description
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.
