Effect Of Vesicular-Arbuscular Mycorrhizae Inoculation And Liquid Organic Fertilizer Application To The Phosphorus Concentration On Soybean (Glycine Max L.) In Soils Post-Coal Mining

Abstract

This study aims to determine effect of Vesicular-ArbuscularMycorrhizaeand Liquid Organic Fertilizerapplication to the phosphorus concentrationon soybeans grown in acid soils of post-coal mining. The research use completed randomized factorial design,consisted of two treatment: (1) Vesicular-Arbuscular MycorrhizaeInoculation, M0= 0 gr, M1= 10 gr,M2=20 gr, M3= 30 gr, and M4= 40 gr per plant. (2) Liquid organic fertilizer application ,P0=0 mL, P1= 10 mL and P2= 20 mLper plant .The results showed that the inoculation of Vesicular-Arbuscular Mycorrhizae as much as 40 grams and 20 mL of Liquid Organic Fertilizer gave the best result to the increased concentrations of phosphorus in plant tissue but did not show any increased in the phosphorus concentrations of soil.
