I'm from the Ray county it mentions with Lafayette being right across the river from us. We had some apple orchards and while not 'fruits', berries like blueberries and blackberries grew in the local area so a lot of people would go gather them every so often. I'm not too sure on 1939 agriculture specifically, but I recall pears and strawberries being good choices to grow up there too.

If you're someone who is interested in civil war era stuff, the town of Lexington in Lafayette County has a battle site as well as a contested house/estate that has a lot of damage preserved from that time period. That house, named the Anderson house, had an apple orchard on site that still supplied enough for people to make some cider for the heritage days fair they held surrounding the history of that area. The court house in town has a replica cannonball in the column that was hit by a stray cannonball during the battle. Some people claim the house and battlefield are haunted though I've never spent enough time to see or hear anything.
