Uji Adaptasi Beberapa Varietas Padi Gogo (Oryza Sativa L.) Lokal dan Kondisi Tegangan Air Tanah yang Berbeda pada Bahan Tanah Ultisol

Abstract

The research was conducted in the greenhouse of the Faculty of agriculture, University of Riau, Pekanbaru Campus Binawidya Km 12.5 from January until July 2016. Trial using completely randomized design (CRD) factorial. The first factor soil water tension consists of 3 levels (pF 1,0-1,97, pF 2,29-2,54 and pF 2,70 - 3) and the second factor upland rice varieties consists of 3 varieties  (Santan, Kalpatali and Si Kuning). Treatment was repeated 3 times. Data results were analyzed statistically operates with anova and Duncan test continued level of 5%. The observed parameters is plant high, the maximum number of tillers, the number of productive tillers, dry weight of plants, harvesting, percentage of grain pithy, weight of dry milled grain and weight of 100 grains. Results indicate the interaction of soil water tension and local upland rice varieties significantly effect to plant hight, no except the maximum number of tillers, the number of productive tillers, dry weight of plants, harvesting, percentage of grain pithy, weight of dry milled grain and weight of 100 grains. Combination soil water tension pF 1 - 1,97 and santan variety is the best combination, because weight of dry milled grain yield tended more.
