Max payout levels

Can somebody tell me what the maximum payouts for the crops are? I've been upgrading payouts for awhile now and I'm just wondering how high the payouts get before you can't upgrade anymore.

Well, I guess nobody's played long enough answer my question. I am on day 149 and I think I've reached max payout for all crops now. The free upgrade screen just gives me the option to upgrade payout for bell peppers to $25 even though they already sell for $25. So the max payout is $25 for all crops except Gladiolus which is $16. Just in case anyone's curious.

Wow Cocoa I am impressed. Your on 149 days I am starting my 41's day and my highest payout is $15.00. I wonder how many days we get to work the farm. Have a great day Cocoa. Happy farming and welcome to the pond.
