Allelopathy is a new field of science, as the term Allelopathycoined by Prof. Hans Molisch, a German Plant Physiologist in 1937. However, no standard methods are being used by various workers due to lack of compendium on the Techniques, hence, the results obtained are not easily comparable with each others. Till now lot of allelopathy resech has been done in various fields of Agricultural and Plant Sciences. However, there is no compilation of various Research Methods used. Every scientist is conducting research in his own way. It is causing lot of problems to researchers working in underdeveloped/Third World Countries in small towns without Library facilities. Therefore, to make available the standard methods for conducting allelopathy research independently, this multi-volume book has been planned. Since allelopathy is multi-disciplinary area of research, hence, volumes have been planned for each discipline. Prof. S.S. Narwal has planned this multi-volume Book Research Methods in Plant Sciences : Allelopathy. Three volumes (Volume 1. Soil Analysis, Volume 2. Plant Protection and Volume 3. Plant Pathogens) of this Book were released during the IV. International Allelopathy Conference, August 23-25, 2004 at Haryana Agricultural University, Hisar-125004, India. Volumes 4. Plant Analysis and Volume 5. Plant Physiology will be released in November, 2006. Three volumes (Volume 6. Cell Diagnostics, Volume 7. Chemistry Methods and Volume 8. Weed Studies) are under preparation. This book consists of 12 Chapters, describing the methods to analyse various nutrients in plants. The Book is devided into two Sections : General and Determination of Plant nutrients. The Section I. General, provides very elementary and basic information about the various equipments and apparatus used to determine plant nutrients and preparation of Reagents etc. Further, methods of collecting plant samples and their digestion have been described. In Section II. Determination of Plant Nutrients, 8 Chapters describes methods of determining various plant nutrients (Carbon, Nitrogen, Phospherus, Potassium, Sodium, Calcium, Magnesium, Sulphur, Micronutrients and Toxic metals).

Plant Pathogens) of this Book have been released during the IV. International Allelopathy Conference, 2004 at Hisar(India). Five volumes (Volume 4. Plant Analysis, Volume 5. Physiological Processes, Volume 6. Biochemical Processes, Volume 7. Forestry/Agroforestry Research and Volume 8. Isolation, Identification and Characterization of allelochemicals are under preparation. Volume 1. Soil Analysis is consists of 20 Chapters, describing the methods to analyse various types of soil properties. The Book is devided into three Sections: General, Physio-chemical properties and Soil microbiology. It provides complete information for Soil Analysis in simple and lucid language. The Figures/ illustrations have been given at appropriate places in text. It will prove very useful to undergraduate and post graduate students and teaching Faculty for Class Room and Laboratory experiments as well as for research.

It provides complete information about the various techniques used for Allelopathy Research in the field of Entomology, Nematology and Weeds. It is written in a simple and lucid language. It will be very useful to undergraduate and Post graduate students and Faculty for used in Class room and Laboratory experiments and research. We are thankful to Prof. G. S. Dhaliwal, Department of Entomology, Punjab Agricultural University, Ludhiana and Prof. V. Mojumder, Division of Nematology, Indian Agricultural Research Institute, New Delhi for Peer Review of Entomology and Nematology Manuscripts.
