This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
俼 combines the person radical 亻 with 育, but the exact historical development and original meaning are uncertain.
A person 亻 beside 育 (nurture/raise) might suggest someone who nurtures or sells, but the meaning is unclear.
For イク, imagine a person 亻 nurturing 育 a seedling: 育 (いく) cues the reading イク.
