As your example is not self-contained (it should be), I cannot show it with
your data.
My preferred way is to reorder outside, because it enforces consistency when
I do several plots.

library(lattice)
barchart(yield ~ variety | site, data = barley,
         groups = year, layout = c(1,6),
         ylab = "Barley Yield (bushels/acre)",
         scales = list(x = list(abbreviate = TRUE,
                       minlength = 5)))
                       
levels(barley$site) = c( "Waseca","Grand Rapids","Duluth","University
Farm","Morris" ,
  "Crookston"  )
  
barchart(yield ~ variety | site, data = barley,
         groups = year, layout = c(1,6),
         ylab = "Barley Yield (bushels/acre)",
         scales = list(x = list(abbreviate = TRUE,
                       minlength = 5)))
