Hi,

I want to analyze the design.

My data is like

Treatment has 8 categories, Blocks has 4 categories and two Replications.

Pl let me know my code is correct or not.

proc glm data=temp;
class Rep treat block;
model resp = treat block Rep ;
run;
quit;

Many Thnaks,

Seems to me that replicates are nested within treatment and block. If that's not correct, then please correct me.

If that is the case, then you want to change the model statement to indicate that fact.

model resp=treat block treat*block;

You most likely also want to test treatment against the treat*block term, not against the residual error (replicate error) which is the default. The treat*block term is the experimental error.

test h=treat e=treat*block;

Or you could do the whole thing in PROC MIXED.
