How is NB being used here - "This way there is no whole NB to getting rice from the plant"

I got this reply in a discussion about cooking rice and why packet rice is better.
NB is Nota Bene from Italian and is "Note Well" in English, but how is "Note Well" being used here.
Can someone tell me the Modern English equivalent of this?
Is it "This way there is no need to note well how to get rice from the plant", which do not seem so convincing to me!
