Optimum Plot Size and Number of Replications for Estimating Forage Yield and Moisture Percentage1

Uniformity trials were conducted with pure stands of three forage species and one mixture of two species. Plot variance decreased with increasing plot size in every case. The relationship was very close and almost completely linear when plot variance and plot size were converted to logarithms. Thus plot size can be used to estimate plot or error variance. In general, increasing replication number reduced error more rapidly than increasing plot size. Using green weight only to estimate dry weight left 10% of the variation in dry weight in error.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
