Pengaruh Amelioran Dan Tegangan Air Terhadap Pertumbuhan Dan Produksi Tanaman Padi Gogo (Oryza Sativa L.) Varietas Inpago 8 Di Bahan Tanah Ultisol
The experiment aims to study the effect of ameliorant and water tension on the growth and yield of upland rice variety Inpago 8 on Ultisol soil and to get the best treatment of ameliorant and water tension in increasing crop productivity of upland rice. This research was carried out in application the Departement of Agrotechnology, University of Riau, from March to July 2016. Factor of agris’s site research with two factors, the first factor the soil water tension with 3 levels ie pF 1,0-1,97, pF 2,29-2,54 and pF 2,70-3,0. The second factor were ameliorant application using 8 levels i.e. control, liming 15,4 g/polybag, rock phosphate 7,7 g/polybag, green manure krinyuh 7,7 g/polybag, liming 15,4 + rock phosphate 7,7 g/polybag, liming 15,4 + green manure krinyuh 7,7 g/polybag, rock phosphate 7,7 + green manure krinyuh 7,7 g/polybag and liming 15,4 + rock phosphate 7,7 + green manure krinyuh 7,7 g/polybag. Parameter observed were: the plant height, the maximum numbers of tillers, number of productivity, day to maturing, root volume, the percetage of pithy grains per clump, dried grain weight, weight of 1000 grains and plant dry weight. The result showed that ameliorant application significantly effected on the maximum numbers of tillers and number of productivity of tillers. Application of ameliorant rock phosphate 7,7 + green manure krinyuh 7,7 g/polybag on pF 1,0-1,97 gave best result on height, number of tillers, number of productive tillers and dry biomass at Inpago 8.
