However, I can just print the three grouped plots onto one page as I'm putting them into a pdf-file, which gives me a huge amount of pages... Is it possible to put them all, or at least more than one on the same page, for instance put three groups beside each other like columns?

I'm not entirely sure what you want, but what about some variant of

xyplot(Pro ~ Glc + Raf + Suc | Categories_BBCH_ID,
data=fieldTrial0809, outer = TRUE,
       pch="°", layout=c(3, 3), aspect=1, as.table = TRUE)
