Allocating too many extents in table

All,
I am using the below oracle version.

SQL> select * from v$version;

BANNER

Oracle9i Enterprise Edition Release 9.2.0.6.0 - 64bit Production
PL/SQL Release 9.2.0.6.0 - Production

TNS for IBM/AIX RISC System/6000: Version 9.2.0.6.0 - Production
NLSRTL Version 9.2.0.6.0 - Production

SQL>

One of my table, it is growing 5000 extents every day. I mean, oracle allocating too many extents every day. I wanted, not to allocate serveral extents. How can i avoid this? Can i change the next_exent or PCT_INCREASE. The tablespace is LMT. This table is partition table.

1 select INITIAL_EXTENT,NEXT_EXTENT,PCT_INCREASE from dba_segments where owner='QUOTE'
2* and segment_name ='INVENTORY'
SQL> /

INITIAL_EXTENT NEXT_EXTENT PCT_INCREASE
-------------- ----------- ------------
65536

Please advise....

Thanks
