Abstract
The lowland rice yield data obtained from the College cooperative performance tests from 1960 to 1966 were used in the study of the effect on plot variability of three methods of plot yield estimation, namely estimates based on actual yield, average stand and perfect stand. The magnitude of the error variance computed from plot data estimated by each of these methods was used as a measure of the degree of reliability of the estimate.
The error variances obtained from randomized complete block and split-plot analyses revealed no essential difference among the methods of plot-yield estimation. The lowest error variance was obtained from a randomized complete block analysis of data estimated from actual stand and from a split-plot analysis of data calculated from average stand. In general, however, the yield estimates based on average stand could be expected to give the lowest error variance.
