which variogram's sill , nugget and range

hello

when I create a directional variogram,  it  usually gives  different 
shaped variograms according to its direction.
(like this cvgm <- variogram(z ~1, data=el4 ,boundaries = seq(0,2000, by 
= 50), alpha=c(0,45,90,135,180,225,270))  )

In these cases,  which  variogram's  sill , nugget  and  range are 
picked up for krig estimation ?

regards
