Repeated measurements (RM) are common in forage experiments. The data used in this study were accumulated ammonia losses by volatilization (N)and dry matter production (DM) of cynodon dactylon cv. Coastcross pasture from an experiment in blocs with five levels of urea: 0,25, 50, 100 and 200 kg of N ha , applied in five periods (Cuttings). For N, RM were the averages of cuttings and nine days of observation. The F test for the hypothesis of no affect for period and level x period interaction (DM) and for days interaction was not affected by univariate and multivariate tests. However, greenhouse-geisser epsilon estimate was biased downwards. Polynomial contrast in univariate ANOVA and logistic function agreed explaining acumulated N. For DM, uneaqual population variances on different was rejected and the assumption that pairs of observations on the same subject are equally correladet was rejected. |
