Abstract
Linear covariance analysis of maize grain yield data using plot stand as the covariate is not satisfactory when the missing plants are eliminated before maturity. This is due to the resulting nonlinear relationship between yield and plot stand. In this paper, the use of exponential adjustment of plot yield for suboptimal stand is demonstrated. The analysis of variance (ANOV A) of adjusted data is compared with the analysis of covariance using the same data set.
