Can you use banana peels as free fertilizer?

A few days ago I received an email, asking me the following question:
“It recently occured to me that the high potassium and phosphorus content of bananas/peels would make them an ideal candidate as an organic fertiliser of peppers, tomatos, tomatillo, cougette, achocha etc. My question is do you have any experience or insight reguarding this? if so any advice on how best to employ the nanas.”
Now I have heard about using banana peels to fertilize roses, but it’s not something I have tried myself – ours just go on the compost. And although it’s a well-repeated idea on the internet, I have yet to find any scientific evidence that suggests it would work or well-respected gardeners who suggest it.
And there are different opinions on the best way to use banana peel as fertilizer. Green (Living) Review suggests baking them first; My Little Garden in Japan turns them into a plant smoothie with eggshells, and Real Simple simply buries them under the rose bush.
What do you think? Do you use your banana skins as fertilizers, and if so, how? Have you read something more erudite on the subject that would shed some light? Are you now wishing you’d brought along a banana for lunch?
While I was going bananas this morning, I came across a lovely blog post on Benvironment about the perils of leaving ‘biodegradable’ banana waste behind when you’re having some time off. But you don’t do that, do you?
