Estimate of Optimum Plot Size for Cotton Yield Trials1
- R. O. Kuehl and
- D. L. Kittock2
We used data from 55 variety trials, four cultural experiments, and a uniformity trial of cotton, Gossypium hirsutum L. (Upland) and G. barbadense L. (Pima), to estimate soil heterogeneity and optimum plot size. Estimates of soil heterogeneity varied primarily with trial location. Optimum plot size was estimated from variety yield trials to be 53 m of total row length, and from a single uniformity trial to be 9 m. Shape of plot has little effect on plot variability.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
