Psychological Effects of Arbuscular Mychorrhiza Fungi Reducing Chemical Fertilizer on The Growth of Oil Palm Seedling

Abstract

Arbuscular mycorrhizal fungi (AMF) are fungi that form a symbiotic relationship with plant roots, supplying nutrients such as phosphorus. AMF can absorb, accumulate, and transport large amounts of phosphate in their hyphae before releasing it to plant cells in root tissues. The purpose of this research is to assess the feasibility of using AMF to reduce fertiliser levels in oil palm seedlings. Plant growth, foliar and rachis status, gas exchange, soil physiochemical, and spore count are among the parameters measured and analysed. Treatments were arranged in a randomized completed block design (RCBD) with 10 replications in four blocks. The finding showed that reducing Tekam Organic Fertilizer (TOF) and Nitrogen Phosphorus Potassium fertiliser rates by 15% with AMF could have an effect on plant growth differences (height, number of leaves, girth size, chlorophyll and leaf area)Total biomass, leaf weight ratio (LWR), and root-shoot ratio all have had significant relationships with growth performance. Furthermore, a significant correlation was found between net photosynthesis and stomatal conductance For plant growth data (palm height, number of leaves, and leaves area (LA) and root biomass of oil palm seedlings, the use of AMF has the potential to reduce the use of Tekam Organic Fertilizer (TOF) and Nitrogen Phosphate Potassium (NPK) fertilisers by 15%. The soil analysis results confirmed that the application increases plant growth, which increases availability.
