Other claims from this paper (3)
- Recommendation The optimum mower-strip sample size for pasture herbage yield should be determined each season.
- Association Confidence intervals for herbage yield tended to decrease as sample size increased.
- Recommendation Harvesting more than 7 mower-strips offers little practical advantage for pasture yield estimates.
