Please, see output of lme and lsmeans. There is also extra output of lsmeans which is what I want.

Thanks for the answer! I changed some part of data and combined treat and year. I called it "Mix". Because when I run the model with year and as interaction term It gave this "Error in MEEM(object, conLin, control$niterEM) : Singularity in backsolve at level 0, block 1" I decided run model diffrently but instead of interpreting output of new model, I ran this lsmeansand I got the output which is below. The problem is I want to see p-value, but model did not give that. My question is How to get P value to output of the lsmeans?
