KEPADATAN POPULASI CENDAWAN PELARUT FOSFAT YANG DIBERI PERLAKUAN TRICALCIUM PHOSPHATE PADA AKAR JAGUNG (ZEA MAYS L.)

ABSTRACT: This research was aimed to observe population density of phosphate solubilizer fungi that treatment  by tricalcium phosphate (TCP) on root of corn (Zea Mays L.). This research used Randomized Completely Block Design (RCBD) with two factor, the first factor was inoculation phosphate solubilizer fungi with 3 levels: without phosphate solubilizer fungi (C0), phosphate solubilizer fungi 1 (C1), phosphate solubilizer fungi (C2) and the second factor was dosage of Tricalcium Phosphate (TCP) with 3 levels: 0 mg per plant (P0), 30 mg per plant (P1), 60 mg per plant (P2). Every treatment has been repeated for 3 times. Thus, there were 27 treatment units with Duncan Multiple Range Test 5%. The observation was consisted of several parameters, that were  population density of fungi in root of corn, population density of fungi on rizhosfer root of corn and popultion density on plant medium. The result of this research showed that phosphate solubilizer fungi 1 given the significantly different population density of fungi in root of corn and popultion density on plant medium; phosphate solubilizer fungi 2 given the significantly different in population density of  fungi on rizhosfer root of corn. While dosage of TCP 30 mg per plant given the best in population density of fungi in root of corn, and popultion density on plant medium. There was an interaction between phosphate solubilizer fungi  1 and dosage of TCP  30 mg in population density of fungi in root of corn, population density of fungi on rizhosfer root of corn and population density on plant medium.
