thank you very much indeed for your answer SteveDenham. yes the treatments was applied to the same plots in both year , so I think, it can addressed as a repeated measures design. I heard about proc anova and proc glm which they do not work correctly in split plot design, but in some references and Class notes anova and proc glm was used for analysis split plot design for one year expriment. the question is that: does that not work correctly for one year analysis? or it doses not work correctly for 2 years combine just? thank you again
