Abstract: The Citrus Research Center and Agricultural Experiment Station (CRC-AES) records collection contains administrative records, correspondence, faculty papers, publications, scrapbooks, clippings, photographs, reports, project files, and other material relating to CRC-AES. Formerly known as the Citrus Experiment Station (CES), the bulk of materials precede the establishment of UC Riverside's College of Letters and Sciences in 1954. The majority of topics document the history, events, faculty, staff, facilities, research, and experiments of CES. Materials related to CES research and experiments pertain to the physiology and morphology of citrus, fig, date palm, avocado, and other subtropical crops, soil management, smog studies, pest control, and diseases. A majority of citrus related publications and faculty papers were originally part of the former University of California Graduate School of Tropical Agriculture and Citrus Experiment Station Library. Project files pertain to research and experiments conducted by CES staff, faculty, and associated members. In addition, other subjects include the history of the citrus and avocado industry in Southern California, the introduction of the first Washington navel orange tree, and global production and marketing of citrus and subtropical agriculture.
Languages: The collection is in English.

Processing History

Processed by History Associates Incorporated, 2013.
Processing of the University of California, Riverside, Citrus Research Center and Agricultural Experiment Station records was generously funded by the Andrew W. Mellon Foundation, and administered by the Council on Library and Information Resources (CLIR). The University of California, Riverside was awarded a Cataloging Hidden Special Collections and Archives grant from 2010-2013, "Uncovering California's Environmental Collections," in collaboration with eight additional special collections and archival repositories throughout the state and the California Digital Library (CDL). Grant objectives included processing of over 33 hidden collections related to the state's environment and environmental history. The collections document an array of important sub-topics such as irrigation, mining, forestry, agriculture, industry, land use, activism, and research. Together they form a multifaceted picture of the natural world and the way it was probed, altered, exploited and protected in California over the twentieth century. Finding aids are made available through the Online Archive of California (OAC).

Administrative History

The Citrus Research Center and Agricultural Experiment Station (CRC-AES) was established by the Regents of the University of California on February 14, 1907. In the late 1800s, the citrus industry was quickly expanding in Southern California causing the need for a research facility closer than the State Agricultural Experiment Station located in Berkeley. In 1899, John Henry Reed, a citrus grower and member of the Riverside Horticultural Club, developed a proposal for the construction of an experiment station in Riverside for the purpose of improving the growth and production of citrus crops. Over the next five years, Reed and his fellow club members created petitions, acquired endorsements, and lobbied the California legislature to have a station developed. In May 1906, a group of commissioners created to represent the UC Regents approved a plan that would allow for the establishment of an organization with two separate branches: a laboratory in Whittier and an experiment station in Riverside.
Initially known as the Rubidoux Laboratory, the Citrus Experiment Station (CES) was constructed on approximately 23 acres of land on the eastern side of Mount Rubidoux in Riverside. Leased to the University of California from the Huntington Park Association, the site was comprised of a few small buildings, two cottages, and a stable. To celebrate the opening of the Citrus Experiment Station on January 27, 1907, Riverside staged the largest Farmers' Institute ever held in California at that time. During its earliest days at the Rubidoux laboratory, CES had only two technically trained staff and few staff assistants, with research limited to topics in soil management, irrigation, and fertilization for the improvement of citrus quality and production.
In 1912, the retirement of Dean Wickson of the College of Agriculture and director of the State Agriculture Experiment Station in Berkeley prompted a decision by the UC president and regents to consider a reorganization of the university’s agricultural research and activities. In 1913, Herbert John Webber was appointed dean of the newly formed Graduate School of Tropical Agriculture in Southern California as well as the new director of CES. In January of that year, a freeze in Southern California caused a record loss in citrus crops, prompting the California Fruit Growers Exchange to lobby for an increase in citrus funding. The result allowed for a new and larger citrus experiment station to be built. In 1914, Webber worked closely with the Riverside Chamber of Commerce and city officials to convince the UC Regents to keep the station in Riverside instead of moving it to the San Fernando Valley. On December 22, 1914, the regents voted 14 to 4 in favor of keeping the station in Riverside. The dedication ceremony for the new Graduate School of Tropical Agriculture and citrus station took place on March 27, 1918 at the new 475 acre site located at the foothills of the Box Springs Mountains, five miles east of the original Rubidoux site.
During his tenure, Webber recruited eleven scientists and organized six divisions within CES: agricultural chemistry, plant physiology, plant pathology, entomology, plant breeding, and orchard management. In June 1917, Webber directed the installation of experimental plots on the new site for the purpose of studying orange cultivation and fertilization. This was the start of the citrus variety collection (CVC), one of the greatest citrus tree varieties collections worldwide. Some of the most important achievements within CES during Webber’s directorship were in biological control, plant diseases, soils and plant nutrition, and studies regarding mottle-leaf disease, the mealybug, and subtropical agriculture with a focus on avocados.
After Webber’s retirement in 1929, Leon D. Batchelor became the second director of CES. During his term, he focused on fertilizer experiments and research on tristeza disease. Through the development of a new rootstock that was tristeza resistant, the threat of extinction of California citrus trees was prevented. In 1932, the University of California at Los Angeles (UCLA) established a College of Agriculture and the Division of Subtropical Horticulture was transferred from Berkeley to Los Angeles. Over the course of the next few years, divisions were transferred from Berkeley, Davis, and Riverside to Los Angeles. This resulted in the Graduate School of Tropical Agriculture being discontinued in Riverside in 1939. In 1946, Webber and Batchelor co-edited The Citrus Industry, a two volume work regarding citrus growth, production, and distribution.
In 1951, Batchelor retired from his post as director and Homer D. Chapman took over until the end of that year. In January 1952, entomologist and CES staff member Alfred M. Boyce became the new CES director. During Boyce’s term, CES expanded its research to include the nation’s first department of Nematology, and dedicated time to research in air pollution and insect resistance to pesticides. In 1954, the Riverside campus established a College of Letters and Science and became a general University of California campus in 1959. In 1960, a College of Agriculture was created at Riverside and Boyce was appointed the first dean. Through this partnership, CES researchers and scientists acquired joint research and teaching appointments. In 1961, CES officially changed its name to the Citrus Research Center and Agricultural Experiment Station (CRC-AES) to reflect new growth and developmental changes within the research conducted at the station. Since the 1960s, the CRC-AES has continued research in areas such as biological control and pest management, and has added new areas in molecular biology, genetics, and agriculture in arid and semiarid regions. In 2007, the CRC-AES celebrated its 100th anniversary. Today, the CRC-AES is administered by Agricultural Operations, a department within the College of Natural and Agricultural Sciences at UC Riverside. Through Agricultural Operations, CRC-AES continues to grow and manage crops for the future research of citrus and subtropical agriculture.
