Model difference



> Hi there,
> 
In the combined analysis of variance > for my unbalanced multi-year multi-location variety trials data,>  I used>  the following models:

(1)		> Yield !WT=wt ~ mu c(trial) check check.trial !r genotype genotype.year genotype.location 
> genotype.year.location !f mv
(2) 		Yield !WT=wt ~ mu c(trial) check check.trial date input  !r genotype genotype.year genotype.location 
> genotype.year.location !f mv
> 
where "date" refers to the planting date of the trials and "input" is the nitrogen level of the trial.

I don't know why I had the same results from the two models. Has the factor "trial" covered all the variation caused by "date" and "input"?
