It's the hidden portion of endeavors which are usually responsible for their growth, and this life principle holds true in one's backyard as well. The 70 contributors to this definitive text on roots uncover the complex system which nourishes those beautiful summer roses. The structure, development, growth, metabolism, waterways, bacteria, and pests (even the root hairs) are examined with thorough and scientific expertise. The second edition has been substantially revised and expanded with the addition of 30 contributors, new chapters on root study methodology and the biosynthetic and medicinal uses of roots, and revised research, particularly in the area of molecular genetics.

Quite simply, this is required reading for anyone involved in managing agricultural research. With a wealth of practical solutions and advice, it offers a how-to guide for managers as well as highlighting the differences in the way that different nations approach this key area of research – one of the most widespread forms of inquiry in the world. The lessons that can be learned from this brilliant study apply in equal measure to developed and developing nations.

Here in one easy-to-understand volume are the statistical procedures and techniques the agricultural researcher needs to know in order to design, implement, analyze, and interpret the results of most experiments with crops. Designed specifically for the non-statistician, this valuable guide focuses on the practical problems of the field researcher. Throughout, it emphasizes the use of statistics as a tool of research—one that will help pinpoint research problems and select remedial measures. Whenever possible, mathematical formulations and statistical jargon are avoided. Originally published by the International Rice Research Institute, this widely respected guide has been totally updated and much expanded in this Second Edition. It now features new chapters on the analysis of multi-observation data and experiments conducted over time and space. Also included is a chapter on experiments in farmers' fields, a subject of major concern in developing countries where agricultural research is commonly conducted outside experiment stations. Statistical Procedures for Agricultural Research, Second Edition will prove equally useful to students and professional researchers in all agricultural and biological disciplines. A wealth of examples of actual experiments help readers to choose the statistical method best suited for their needs, and enable even the most complicated procedures to be easily understood and directly applied.
