Pemberian Beberapa Sumber Fosfor Dan Bahan Pemicu Penyerapan Fosfat Pada Tanah Ultisol Untuk Pertumbuhan Dan Hasil Padi Gogo (Oryza Sativa L.)
This study aimed to determine the effect of the allotment some source of phosphorus and phosphate absorption triggers on upland rice plants as well as to get the best treatment to increasing the growth and yield of upland rice on Ultisol soil. The research was conducted in experimental station in agriculture faculty, Riau University from May 2016 until September 2016. The experiment uses the method completely randomized design (CRD) factorial consist two factor. The first factor is Sources of phosphorus with three levels, namely: without fertilizer P, rock phosphate and TSP and the second factor is phosphate absorption triggers with three levels, namely: arbuscular mycorrhizal fungi, bacterial solvent phosphate and vermicompost. Data analyzed by analysis of variance (ANOVA) and further tested using by Duncan`s New Multiple Range Test (DNMRT) at the level of 5%. The parameters measured were the number of maximum tillering, the growth rate of plants, plant dry weight, number of productive tillers, panicle length, number of grains per panicle, percentage of pithy grain, by weight of dry milled grain, weighing 100 grains, the levels of P and the percentage of infected root mycorrhizal. The treatment of natural phosphate rock + vermicompost provide the highest yield in the maximum number of tillers, plant dry weight, number of productive tillers, number of grains per panicle, dry milled grain weight and weight of 100 grains.
