FAQ

How can I get a print copy of the annual eFields Research Report?

  • There are several ways you can obtain a hard copy of the eFields Research Report:

    • Contact your county Extension Educator to see if they have available copies.

    • Email digitalag@osu.edu with your name and address to request a hard copy.

    • Plan to attend one of our regional research meetings (details coming soon)!

Why are randomization and replication important?

  • Replication allows us to estimate the error associated with carrying out the experiment itself. A minimum of 3 replications are needed for a field study, with more than 3 recommended to ensure that treatments are thoroughly evaluated. Without replication, it would be impossible to determine what factor or definite cause contributed to any treatment differences.

  • Randomization is just as important as replication to help account for any variations. Even if you replicated treatments, the conclusions you reach may not be correct if a treatment was always applied to the same part of the field. Randomization prevents data from being biased based on its location in a field. 

  • Tools such as Ohio State PLOTS, which utilize a Randomized Complete Block Design (RCBD) analysis, are a great way to ensure that you replicate and randomize your treatments appropriately. See the Study Tips & Tricks page to get the download links for iOS and Android devices.
