PENGARUH INOKULASI FUNGI MIKORIZA ABUSKULAR DAN BIOKTIVATOR (MENGANDUNG JAMUR Trichoderma spp. DAN EKSTRAK DAUN LEGUNDI) TERHADAP PENYAKIT LAYU FUSARIUM DAN HASIL BAWANG MERAH

Abstrak

The aim of this research is to know the effect of inokulation Arbuscular Mycorrhizal Fungi (AMF) and bioactivator containing T. harzianum isolate Sapro-07 and T. koningii isolate Endo-02 against Fusarium wilt disease incident and yield on Onion. This research was conducted from April 2017 until November 2017. The research was conducted in farmer's field which is endemic area of Fusarium wilt disease on Onion in Senteluk Village, Batu Layar Sub District, West Lombok Regency. The research method used is experimental method with Split Plot Design by two factors. The main plot is AMF inoculation consisting of 2 levels, ie: without AMF and with AMF. The subplot is a bioactivator application consisting of 5 levels, ie: without bioactivator, bioactivator fluid containing Trichoderma spp. Fungus, bioactivator tablet containing Trichoderma spp., Bioactivator liquid legundi leaf extract containing Trichoderma spp fungus, bioactivator legundi leaf extract containing Trichoderma spp. fungus. The observed variables were Fusarium wilt disease and yield. Observational data were analyzed using Analysisof  Variance with 5% real level and tested further by using Honestly Significance Different test at 5% error level. The results showed that AMF inoculation can suppress the incident of Fusarium wilt disease on Onion. Similarly, bioactivator application of legundi leaf extracts of fluids and tablets containing Trichoderma spp fungus. can suppress the incident  of Fusarium wilt disease and yield on Onion
