    Abstract

    Betta Dwi Isti Ferela. H 0203003. Efficiency of P Uptake in Andisols of Tawangmangu by Vermicompost Addition and Potato (Solanum tuberosum L.) as a Plant Indicator. Mostly potatoes (Solanum tuberosum L.) are planted on Andisols that have problem in phosphate fixation. The aim of this research were to know the efficiency of P fertilizing in Andisols that were added Vermicompost and SP36 and to know potatoes yield in Andisols of Tawangamangu. This research was conducted at Tawangmangu, Karanganyar on October until December 2007. The method used was split plot design, as a main plot was Vermicompost, i.e. no Vermicompost and 10 ton.ha-1 Vermicompost. Sub plot consist of four levels of P fertilizer (SP36), i.e. 100, 250, 400, 550 kg.ha-1 and control. The observation variables are available P, P absorption, efficiency of P absorption, height of plant, weight and diameter percentage of potato tuber. F test, Kruskal-Wallis test, and DMRT 5% test is used to analysis data. The result of this research shows that there is interaction betwen Vermicompost and 400 kg.ha-1 dozez SP36 to highest available P in the soil is 2.157 ppm P2O5, but there is no interaction on yield. The addition of 10 ton.ha-1 Vermicompost can increase weight of potato tuber (30.83 %), height of plant (13.36 %), and decrease percentage of potato tuber amount diameter in < 9 cm (48.05 %). Addition of 250 kg.ha-1 SP36 can increase percentage of potato tuber amount diameter in 12-15 cm (57.46%). The highest result of potato is reached on tuber diameter > 15 cm (37.16%) with 10 tons.ha-1 Vermicompost additions. Keywords: Vermicompost, P fertilizer, potato, Andisols
