It was listed on the National Register of Historic Places in 1994.[1] At the time of its nomination it contained three resources, which included two contributing sites, and one contributing structure.[2] It includes four strands of top-worked apple trees that were planted 1933 to 1934, and a windbreak of Ash and Mulberry trees that were planted in 1936. They both count as the sites, and the structure is a network of traffic corridors that were established 1933 to 1934. Its historic significance comes from the symbiotic relationship between science and practice in Iowa agriculture.[2] They used planting techniques that were advocated by researchers at Iowa State College, now Iowa State University, and carried out by progressive fruit growers like Hugh and Roscoe Byale. In this instance they employed Hibernal root stock and top-work grafting. The Armistice Day Blizzard in 1940 wiped out most of Iowa's apple orchards, but it validated the techniques employed here.[2] References1. ^1 {{NRISref|2009a}} {{National Register of Historic Places}}{{NRHP in Jasper County, Iowa}}{{Iowa-NRHP-stub}}2. ^1 2 {{cite web|url={{NRHP url|id=94001255}}|title=Byal Orchard Historic District|publisher=National Park Service|accessdate=2016-04-12|author=William C.
