Which option correctly describes the basis of the One-Third Rule according to the material?

Which option correctly describes the basis of the One-Third Rule according to the material?

• A. It was based on published studies in common turf species
• B. It was based on research of a specific species not listed here
• C. None of these answers
• D. It was derived from general mowing guidelines

Answer: (C)

The One-Third Rule is a practical mowing guideline focused on protecting the turf plant’s ability to recover. By removing only about one-third of the leaf blade at each mowing, you preserve enough leaf area for photosynthesis to continue and for the plant to build stored carbohydrates and roots, helping it recover quickly after mowing. The material isn’t describing the basis as coming from a specific published study in a turf species, nor from research on a particular species, nor simply as a general mowing guideline. Instead, it presents this rule as a conservative, experience-based guideline rooted in how turfgrass physiology responds to defoliation. That combination of physiology and practical experience isn’t captured by the other stated options, so the correct choice is none of the listed descriptions.
