"The Strawberry Festival provides you with approximately 500 Food for every 10 minutes of game length, up to 30 minutes."
In-game description

Strawberry Festival is a Big Button technology in Age of Empires III: The WarChiefs that is unique to the Iroquois and can be researched at the Farm. Once researched, it ships 500 food for every 10 minutes the game has passed, up to 30 minutes (for a total of 1,500 food).

Note that if Strawberry Festival is researched before the game time reaches 10 minutes, no resources will be shipped, wasting the cost.
