Excerpt from Experiments in Field Plot Technic for the Preliminary Determination of Comparative Yields in the Small Grains
During recent years the investigation of the reliability of field experiments has become an important phase of agronomic research. Field experiments as ordinarily conducted have been shown to be affected by many gross errors. In the light of these investigations it has become apparent that the results of many of the older experiments are inconclusive or even misleading. Various expedients have been suggested for counteracting experimental error. Some of these have been quite successful, while others have probably done more harm than good.

Paperback. Condition: New. Print on Demand. This book explores the field plot technique used in preliminary assessments of crop varieties. Namely barley, oats, and wheat when grown in small plots. The research presented here is the result of experiments conducted from 1919 to 1921. Using the data from these experiments, the author makes a case for plot size, replication, and adjustment to border row error as factors affecting accuracy. The experiments show that the size and replication of plots and whether yields were adjusted by means of check plots significantly affected variability. This book provides vital information for improving the accuracy of preliminary variety tests for small grains and identifies several errors that can markedly affect the outcome of such tests. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
