Uji Adaptasi dan Karakteristik Iklim Mikro Beberapa Varietas Padi Gogo (Oryza sativa L.) Adaptation Test and Characteristic Micro Climate in Some of Upland Rice Varieties (Oryza sativa L.) Ahmad Ema Farma1, Taufan Hidayat1, and Erida Nurahmi1, 1)Agrotechnology Department, Agriculture Faculty, Syiah Kuala University, Banda Aceh 23111 Indonesia. ABSTRACT The purpose of this research is to examine adaptation and micro climate in various of upland rice varieties which being cultivated in lowland. Execution of the research in Turam Village, Darul Kamal District, Aceh Besar, Regency of Aceh Besar, Nanggroe Aceh Darussalam, since September 2012 until February 2013. The seed that being used in this research consists of 5 upland rice’s seed varieties, obtained from Pemuliaan Tanaman Agriculture Faculty University of Syiah Kuala Laboratory. The five varieties are Towuti, Situ Bagendit, Limboto, Situ Patenggang, and Inpago 6. The research type is Group Random Design non factorial with 5 varieties conducts, and 3 examinations, so that present 15 experiment units. The experiments execution involve first the plant growth consists of length of plant, amount of productive tillers; second, the potential of production result per hectare; and third, micro climate involves percentage of solar radiation interception, air temperature, air dampness, and soil temperature. Upland rice varieties in lowland influence length of plant at 6 and 8 weeks after planting and flowering time, and only significantly differ in amount of productive tillers and rice production per hectare (ton ha-1), whereas micro climate consists of percentage of solar radiation interception, air temperature, air dampness, and soil temperature do not significantly different in each varieties.
