I don't think it's fixed. Just yesterday I had a harvest (in good conditions and with 99 quality dung fertilizer) and only yielded 1-3 crops max.
And my crops today have, vanished, literately, ever since the last 0.8.2.3 patch everyone's crops have been invisible and now today I log in and find my entire field is empty. Every single tile was planted on, now it's just dirt. They weren't even ready yet.
And no, I play on a private locked server so it wasn't a player trolling.
EDIT: found out the GM was playing with the GROW command and ended up rotting our crops. He replaced it though.
