As an alternative, have you considered separating the groups by white 
space. For example:

\starttext

\bTABLE[frame=off, loffset=0.5em]
   \bTH
     \bTD Parcel \eTD
     \bTD Area   \eTD
   \eTH
   \bTR
     \bTD[nr=3, align={lohi}]
       Parcel 1
     \eTD
     \bTD 1 acre trees \eTD
   \eTR
   \bTR
     \bTD 2 acre vines \eTD
   \eTR
   \bTR
     \bTD 3 acre open \eTD
   \eTR
   \bTR[topdistance=\lineheight]
   \bTR
     \bTD[nr=3, align={lohi}]
       Parcel 2
     \eTD
     \bTD 5 acre trees \eTD
   \eTR
   \bTR
     \bTD 6 acre vines \eTD
   \eTR
   \bTR
     \bTD 4 acre open \eTD
   \eTR
\eTABLE

\stoptext
