The readability formula developed in the present study has direct application in the field of education, mass communication, journalism and agricultural extension. The developed formula can be used by the communicators, writers and authors to know the grade level of the writing. Hence, it would be possible to modify the level of difficulty to suit to the required literacy level of the readers. The formula will be particularly helpful for prior testing of material before publishing it for the benefit of readers in general and farmers in particular. By using the present readability formula, it is also possible to analyze the already published extension literature and other publications to determine their suitability to the intended readers. This work will provide the required feedback for communicators and writers to appropriately modify the written material for the benefit of readers.
