This is a complete guide to get familiar with the techniques to draw reliable conclusions from on-farm trials. Emphasis is on the experimental aspects of on-farm research, which should help on-farm researchers to arrive at solid conclusions, taking into account, rather than eliminating, variation among farmers

This text provides statistical and biometrical procedures for designing, conducting, analyzing and interpreting field experiments. It addresses the most important research topics in agriculture, including agronomy, breeding and pasture trials; farming systems research; and intercropping research.

"This book brings to life one of the most creative (and necessary) human endeavors and makes understandable the incredible complexity of California agriculture, one of the world's most daring experiments in feeding itself. A valuable resource that should be read by everyone—not just those of us who farm, but all of us who depend on farms."—Michael Ableman, farmer, photographer, and author of From the Good Earth, On Good Land, and Fields of Plenty. "No understanding of this state is possible without an understanding of its agriculture; that's how important this subject is."—Gerald Haslam, author of Workin' Man Blues: Country Music in California "A fascinating, intriguing, and sometimes even humorous exploration of California's agriculture, from broccoli to marijuana and beyond. At long last, a book everyday people can read to understand the state's biggest industry."—Louis Warren, University of California, Davis
