Batchelor taught horticulture at
Cornell University from 1907 to 1910 and resigned to teach at
Utah Agricultural College. While teaching at Utah, Batchelor published studies about
thinning apple orchards. In 1915, he joined the
University of California Citrus Experiment Station as an Associate Professor of Plant Breeding. Batchelor was promoted to Professor of Orchard Management in 1919 and to director of the Citrus Experimentation Station in 1929 to replace retiring director
Herbert John Webber. Batchelor became a preeminent authority within California on the study of
walnuts. He was named by the state director of agriculture in 1940 as the seventh member of the California Walnut Control Board. Batchelor remained director of the Citrus Experimentation Station until July 1, 1951, when he returned to research. Batchelor was selected as the
University of California, Riverside's Faculty Research Lecturer for 1954. Batchelor Hall on UC Riverside's campus is named after Batchelor, the longest-serving director of the Citrus Experimentation Station. ==Selected published works==
