Hi Tahir, As far far as I know most kriging modules in GRASS were discontinued. But v.krige is being developed in GRASS7 and it will do just what you are after. see here: http://grasswiki.osgeo.org/wiki/V.krige_GSoC_2009
But if you are willing to invest more time you can run R Within GRASS and it will give you access to a whole array of geostatistical options through packages like gstat, geoR ...etc. Google R+GRASS and you will find a lot of information on how to do it. You can start here: http://grasswiki.osgeo.org/wiki/R_statistics Hope it helps. Cheers.
