PEMANFAATAN KOMPOS TRICHO-AZOLLA SEBAGAI BIOPESTISIDA DAN BIOFERTILIZER PADA PEMBIBITAN KELAPA SAWIT

Abstract

Biopesticide and biofertilizer is an attractive alternative to the strong dependence of conventional agriculute on synthetic pesticides and inorganic fertilizer, which caused enviromental pollution and development of resistance strains. Azolla can fuctionable as a biofertilizer if combine with Trichoderma pseudokoningii as decomposer and biological control agent, which is expected later can act effectively to promote growth and sustainability of oil palm seedling againt Ganoderma boninese in Nursery.The aim this research to assess potential and synergy and benefits as biofertilizer if combined with Trichoderma pseudokoningii as decomposer, biopesticide, induce systemic resistance and Plant growth promoting agent. The result of this research showed that higher doses of Tricho-Azolla(50g/polybag) can suppressed the G. boninese until 86.92% so that can occur induce systemic resistance. Oil palm seedling are infested with Tricho-Azolla at dose 50 g/plybag to increase the growth oil palm in the nursery and which followed the increase of root crown.
