Abstract: In the South-Central Timor, mandarin orange were first planted in the Tohu village, Mollo district and were commonly called as "Lemon China" (Chinese Lemon) by local people. The So E mandarin are commonly propagated in two ways, both vegetative and generative. The oranges are planted at the beginning of rainy season, or in the dry season if water is available. The number of SoE mandarin population in 2001 was 854.786. In 2002, the populations decreased up to 725. 435. Therefore, the production of the oranges was also affected. The production in 2001 was 10,418 quintals, while in the 2002 the production fell up to 9,698 quintals. The decrease occurred as a result of bad agronomical practice done by orange farmers, plant pests and diseases, and environmental condition. The SoE mandarin has a specific character that cannot be found in any other orange varieties in Indonesia. The purposes of this research were to identify the agronomical practice done by the local orange farmers and environmental condition found in the region. Results of this research will provide more information on the obstacles faced in growing the SoE tangerine oranges. The soil types of the three areas observed in the research are alftsols and ultisols soil, where the level of macro elements is low. The rainfall averages in Boentuka, Nusa, and Ajaobaki can be categorized to type D rainfall level (Schmidt and Ferguson, 1951). The plant pests attacking the SoE mandarin are primarily the black aphids (Toxoptera citricidus), leaf miner (Phyllocnistis citrella), and citrus psyllid (Diaphorina citri). The diseases found were diplodia gummosis (Botryodiplodia theobromae), brown rot gummosis (Phytophtora nicotianae var. parasitica), powdery mildew (Oidium tingitaninum), and Citrus Vein Phloem Degeneration (CVPD). To develop agribusiness oriented orange farming, attention should be given to the agronomical aspect, especially the maintenance of the trees. A regional governmental program is needed to help farmers understand about good maintenance of the trees and product marketing.
