Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 a great pressure on the non renewable fossil fuel resources, which cannot last indefinitely. Besides, indiscriminate use ofpesticides for pests (weeds, insects, nematodes, pathogens) control has resulted in serious ecological and environmental problems viz. , (A) Increasing incidence of resistance in pest organisms to important pesticides. (B) Shift in pests population, particulary in weeds and insects. In weeds, species that are more closely related to the crops they infest have developed. In insects, scenario is most grim, the predators have been killed and minor insect pests have become major pests and require very heavy doses ofhighly toxic insecticides for their control. (C) Greater environmental pollution and health hazards (a) particularly from contamination of surface and underground drinking water resources and (b) from their inhalation during handling and application. (D) Toxic residues of pesticides pollute the environment and may prove hazardous to even our future generations. (E) Some agricultural commodities may contain minute quantities ofpesticides residues, with long tenn adverse effects on human and livestock health. Therefore, serious ecological questions about the reliance on pesticides for pests control has been raised. The use of fertilizers, besides causing environmental problems has also impoverished the soil health and decreased the beneficial soil fauna. For example, in some major crop rotations viz.

Download or read book Allelopathy in Agroecosystems written by Ravinder Kumar Kohli and published by CRC Press. This book was released on 2001-08-17 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Allelopathy in Crop Production written by S.S. Narwal and published by Scientific Publishers. This book was released on 2012-11-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Managing Agricultural Residues written by Paul W. Unger and published by CRC Press. This book was released on 1994-03-16 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many agriculturalists, conservationists, and environmentalists are stressing the importance of sustaining soil productivity so that future generations will have adequate productive land on which to produce food. One significant factor affecting soil productivity is the retention of crop residues on the surface of the soil to help control soil erosion. This book provides a review of the vast amount of literature on the subject, condensing the findings in a comprehensive, easy-to-understand manner. It focuses on topics such as erosion control, crop production in systems involving surface residues, residue use for fuel and animal feed, plant pathogens, insects, soil properties, and the economics of conservation tillage.
