Klingen, Ivan Nikolaevich
Born 1851; died 1922. Russian agronomist, specialist in subtropical crops.
Klingen graduated from Moscow University and the St. Petersburg Academy of Farming and Forestry (today the K. A. Timiriazev Moscow Academy of Agriculture). In 1892 he became an inspector of Caucasian appanages. He concluded from a survey of the regions under his jurisdiction that tea could be grown in Transcaucasia. In 1895–96 he took part in an expedition to Egypt, India, Ceylon, China, and Japan to study subtropical plants (tea, citrus, bamboo) for possible introduction to Russia. Klingen is also known for his works on grass cultivation and for making clear the importance of clover pollination by bees as a means of increasing clover-seed yield.
