Parmar. Author index. Subject index. "Neem is a versatile tree of Indian origin. Since ancient times, its various plant parts have been used to control domestic insects, stored grain pests, crop pests and human and livestock medicine. Recently, these properties have been attributed to hundreds of chemicals present in this golden tree. Being a storehouse of chemicals, with multiple uses and adaptability to diverse habitats and climatic conditions, the developed countries have been shown keen interest in this tree. Besides, the present day pesticides and nitrogen fertilizers pose several problems viz., environmental pollution and related health hazards in human and livestock, development of resistance in organisms to pesticides and death of beneficial insects. While neem chemicals have shown potential as pesticides and as nitrification inhibitors and do not pose these problems; moreover, neemcake is used as manure. Therefore, keeping in view the importance of this tree, a session of Neem in Current Context was held at the International Symposium on Allelopathy in Sustainable Agriculture, Forestry and Environment, New Delhi during September 6-8, 1994. There were 20 presentations on neem, during this conference. Keeping in view the keen interest of participants, it was decided to bring out a separate book based on updated world literature which would include the presentations made at the symposium as well as a few others, from well known neem researchers. "In the last eight years, many books have been published on neem, but this book is unique in following ways : (a) it deals with improving production technology of this wonder tree, (b) it provides current status of neem research in production of agricultural and horticultural crops and (c) the book outlines recommendations on the use of neem and its products in crop production and plant protections. "This book will be most useful to neem scientists working in agriculture and forestry and to environmental conscious farmers of developed countries and to the educated farmers of Third World countries intending to practise sustainable agriculture."

It was translated from Czech language because the English is read in most countries of the world hence the Allelopathy scientists would be able to know the phenomenon of coactions and competition in plants. The Allelopathic interactions in coactions and competition in higher plants greatly influences the productivity of field crops fruits trees and forest trees in natural and managed ecosystems. In tropic and subtropical countries many crops are grown in crop mixtures owing to their several advantages. Likewise in natural forests many tree spp. grow together besides many herbs and shrubs grow underneath their canopy. Now due to increased human population the farmers to meet the diverse requirements of their families grows several crops with trees called Agroforestry. However little information is available about the Allelopathic interactions in coactions and competition in the above agro ecosystems. Worldwide it is the only book available on these important aspects. This book will provide inspiration and in depth knowledge of the coactions and competition in higher plants. This book will be very useful for the researchers teachers and students of Biosciences (Plant ecology Plant physiology Biochemistry Microbiology) and Agricultural Sciences (Agronomy Forestry etc.). 220 pp.

Hardcover. Zustand: New. Contents: Preface. 1. Introduction. 2. Allelochemicals. 3. Interactions between plant communities. 4. Exploitation of allelopathy for crop production. 5. Removal of phytotoxins from agricultural lands. 6. Future prospects. 7. Glossary of crops and weeds. Appendix. References. "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 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 agrohorticultural systems of developed countries. Therefore, it may be one of the strategies to increase agricultural production in sustainable agriculture of 21 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. This book will be of great use to students, academicians, scientists and intelligent farmers throughout the world. It may also serve as a text book to the agricultural students." (jacket).

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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.
