Welcome to the website for Rob-Mar, Inc., a family-owned farm in southeast Iowa, straddling Keokuk and Mahaska counties. The name Rob-Mar is a conjunction of the names of the farm founders, Robert and Marlene Hammes. Unfortunately, Robert passed on in July of 2017. However, Marlene remains active along with her son Russell in the day-to-day operations of the farm. The major activities of the farm include growing corn and soybeans. While we no longer raise hogs or cattle, we do have some livestock -- peacocks and elk. The nearest "big city" is Oskaloosa.
