Abstract


This research topic is the effectiveness of Aspergillus niger and Penicillium sp. in increasing
phosphate and growth of corn on Andisol. The objective is to compare the effect of Aspergillus
niger application with Penicillium sp. in increasing phosphate and corn growth on Andisol.
Andisols material was taken from Kuta Rakyat Village, Namanteran Subdistrict, Karo District. This
research was conducted at green house, Soil Biology Laboratory, and Soil Fertility and Chemistry
Laboratory. The design used was non factorial blocky randomized which consists of seven
treatments and four replications, they are M0 (kontrol), MA1 (Aspergillus niger 8 mL), MA2
(Aspergillus niger 17 mL), MA3 (Aspergillus niger 25 mL), MP4 (Penicillium sp. 10 mL), MP5
(Penicillium sp. 18 mL), MP6 (Penicillium sp. 30 mL). Parameters measured in this experiment are
soil pH, soil available-P, plant P absorption, shoot dry weights, and root dry weights.
The results of this research showed that the application of Aspergillus niger and Penicillium sp. non
significantly affected available P, P-uptake, soil pH, and shoot dry weights, but significantly
affected root dry weights and diameter of stem.
Keywords : aspergillus niger, penicillium sp., Andisols
