Is the value static? if so, just define the variable in the crontab
file. And you can change to shell used by the crontab file - it it
makes things easier. I believe the default shell is /bin/sh - which
should source ~/.bashrc - when starting up any cronjobs.

For eg:

-------
ARG   = arg1 arg2 arg2
SHELL = /bin/tcsh
ENV_VARIABLE_USED_BY_MY_SCRIPT = val

1    0 * * * /home/foobar/script ${ARG}
