Introduction

The reports contained in this booklet are the results of the research plot work conducted at Farm Focus and participating Van Wert County farms.  Most of the research conducted by Van Wert County Extension is systematically designed to give a reasonable assurance that the results of an experiment will provide answers to questions under investigation.  To achieve this goal we utilize three key statistical concepts: randomization, blocking, and replication.

Using three blocks (or replications) is the absolute minimum for conducting reliable statistical analysis.  All research trials in this report used at least three replications of the treatment compared, with each treatment being randomly assigned in each block/replicate.  The reports “Marketing Wetlands for Profit” and “Herbicide Demonstrations” are not replicated trials, so the results are not statistically analyzed as to whether the differences between the treatments are significant.  Below are some definitions of common statistical references used throughout the book:

F - The F statistic is used to help identify if the differences between treatment means are due to background noise or the actual treatment.  If there are no differences between treatments, the F statistic will be less than or near 1.

LSD (P=0.05) - Least Significant Difference (LSD) tests for significance between individual treatments.  Two treatments are considered statistically different if they differ by more than the LSD.  For example, if a given hybrid yields different from another hybrid by as much or more than the LSD value, then we are 95% confident that the yield difference is real.

CV (Coefficient of Variation) - The CV is a measure of relative variation.  When comparing two trials, the trial with the lower CV has relatively less variation.

Statistically significant difference - A difference that is beyond what might be expected by chance alone. 

Means significantly different at P = 0.05 - This phrase indicates that 5 times out of 100 the so-called significant difference will not be due to the treatment, but rather, the difference will be due to sampling error.

The information in this booklet is the result of the efforts and contributions of a lot of people and corporations, and it is our desire to recognize and “THANK” them for their support.

v      Cooperating Seed and Chemical Companies for donating seeds, herbicides, insecticides, fungicides, and fertilizers used in the plots.

v      Marsh Foundation and Vantage Career Center for their support of farm ground.  Special thanks to Randy Patterson and Larry Shields from the Marsh Foundation for their help in planting and harvesting season.

v      Farm Focus Research Committee for their help in deciding and planning the research to be done.

v      OSU Extension Support Staff- Marilyn Reed and Deb Knapke, and Green Thumb enrollee Janet Schmidt for their help in preparing the booklet.

We believe this booklet provides a valuable, unbiased source of information for farmers to use as a decision making tool in their operation.  We also want to thank you, the farmer, for your continued support and interest in this prog
