Biological weed control. 16. Glossary of terms in weed science. References. Appendix. The present text book has been specially written keeping in view the biology, ecology and control besides economic importance of weeds present in hill eco-systems. An understanding of the biology and identification of different weed flora helps in better control with less expenses. The various chapters of this have been scrutinized by different scientists of Tamil Nadu agricultural University and ICAR institutes. There are chapters dealing with ecology biology of weeds and their control which provide classification propagation dispersal and useful information on crop weed competition and methods of control. There are chapters on weed management in plantation crops, vegetables, cropped and non-cropped areas, obnoxious weeds and parasitic weeds. (jacket).

The book entitled Weed Management is an attempt of its first kind to highlight the importance of biology ecology and control of prevalent weed flora in temperate tropical and sub tropical situations in India. Herbicides were developed and availability of selective herbicides brought revolution for timely effective and economic control of weeds in crop fields. This book assesses the earlier attempts made in the country and else where. There are chapters dealing with ecology biology and control of weeds utility and harmfulness of weeds information on temperate tropical and sub tropical weeds parasitic and problem weeds and their control fate of herbicides in soil and plants application methodology and use of adjuvents etc. The present publication was planned to make aware of scientific progress and newly emerging concepts like integrated weed management herbicide residues and environment to scientists involved in teaching research and extension. 560 pp.

Glossary. References. Crop science theory and practice is a Working text book. It is the result of continued efforts to provide students with textual material that emphasizes fundamental concepts underlying crop science and production. In addition to updating and revision of chapters also represents efforts to integrate basic concepts of sustainable agriculture and environmental awareness throughout the text. It is designed to embrace concerns and questions related to agriculture, horticulture, environment and plant protection of our natural resources rather than ignore them. The text purposefully emphasizes basic concepts illustrated with suitable crop examples. The text allows the teacher to enhance the students understanding and application regions using lecture discussion or other instructional formats.
