Hey, not sure what your situation is like but i know one of my friends who now runs a fish farm used Heritage Bank, you can check out how they've helped bigger guys here, but i think they help people like my friend who are just starting out, http://www.pulse.ng/business/heritage-bank-diversification-is-the-key-to-recent-run-of-success-id6883725.html

Hey guys, I don't know much about BOA but I've been doing my own research and came across this article: http://www.pulse.ng/business/heritage-bank-diversification-is-the-key-to-recent-run-of-success-id6883725.html

Seems like Heritage Bank has a big push on to support SMEs/entrepreneurs in agriculture. A friend said they've changed under the new CEO/MD dude Ifie Sekibo. Here's something on him, seems pretty switched on: https://dailytimes.ng/business/heritage-bank-supports-triton-group-reforestation-project-oyo/

Anyway, hope this helps. Maybe these guys are better than BOI even though they're not purely an agriculture bank, just a business bank i guess.

Cheers, Remy
