Abstract : Until now, corn is still the second strategic commodity after rice because corn is a cereal commodity with high economic value. This experiment was conducted in Moncok, Ampenan District, Mataram City, at the Microbiology Laboratory and Soil Physics and Chemistry Laboratory, Faculty of Agriculture, Mataram University. The experimental design used was a Randomized Block Design (RBD) with three replications and five bio-ameliorant treatments, namely: P0: Control (without bio-ameliorant), P1: bio-ameliorant dose 5 tons/ha , P2: bio-ameliorant dose 10 tons/ha, P3 : bio- ameliorant dose 15 tons/ha , P4: bio-ameliorant dose 20 tons/ha. The observation data were analyzed using analysis variance followed by the honest significant difference test at a 5% significance level. Research results show the 20 t/ha bio-ameliorant treatment gave the best results compared to other bio-ameliorant treatments. Treatment with a bio-ameliorant dose of 20 t/ha gave the highest NP nutrient concentrations, and yield compared to other bio-ameliorant treatment. Treatment with a bio-ameliorant dose of 20 t/ha provided the best mycorrhizal development compared to other bio-ameliorant treatments.

Keywords : Concentration nutrients, mycorrhiza, soil fertility.
