Towards the end of World War I, "extension agents" began to play a very important role in northeast Georgia. These people, as a group, supported the end of the one-crop "(cotton)" economy. Throughout the state they began to educate farmers in crop diversification so that if one crop failed income from other crops could support the family. In Gwinnett, Cherokee and Hall counties, farmers increased production of dairy products. The peach crop in Bartow County was expanded. In Habersham and Gilmer counties farmers increased production of apples and peaches.
