Abstract
Yield table of Turkey oak by the Forest Research Institute’s long duration research network was publicised in 1974 by Gábor Hajdú, and later in 1983 by Ferenc Kovács. Since then, a great amount of data was accumulated from the University of Sopron – Forest Research Institute’s (UOS – FRI) long duration forest yield and silvicultural research network by continuous recordings. From that database new yield functions and yield tables were made in favour of more accurate estimation of Turkey oak yield. 958 digitalised records from 343 parcels were processed, from that great differences were noticed compared to the previous tables. Besides making the traditional yield table, the methods of calculations were given in detail, from which a forest stand’s individual growth trends can be calculated. The tables were made assuming a 100% Turkey oak mixture ratio, closure and density.
