Increasing of oil palm seedling vigor through seed enrichment with Trichoderma asperellum, Arbuscular

Abstract

Oil palm is a leading commodity of the plantation sector in Indonesia. Improving the quality of oil palm still be carried out to increase production. Seed technology can be used as an effort to improve the quality of oil palm seeds. The aim of this experiment was to determine the effect of seed enrichment with consortium of three microbes to increase vigor of oil palm seedling in pre nursery stage. The experiment design of this reseach was using completely randomize block design consisted of two factors. The first was seed coating consist of two factors, ie: coated seed and uncoated seed. Second was seed enrichment consist of eight factors, ie: control, enrichment with E. sacchari, abruscular mycorrhizal fungi (AMF), T. asperellum, E. sacchari+ AMF, E. sacchari+ T. asperellum, AMF + T. asperellum, E. sacchari+ AMF + T. asperellum. The result showed that enrichment with consortium of three microbes could increase vigor of oil palm seedling based on seedling germination, rate of germination, palm height, and numbers of survival seedling.
