A greenhouse experiment was carried out to study the efficiency of Arbuscular Mycorrhizal fungi indigenous to Arunachal Pradesh in uptaking plant nutrients for the Piper mullesua plantlets at different levels of phosphatic fertilizer (Single Super Phosphate). In plants, P availability is considered the second most important limiting factor for growth after nitrogen. While P is generally abundant in soil, it is mostly present in insoluble and poorly mobile forms and therefore partly unavailable to plants. Mycorrhiza develop a dense hyphal network that extends far into the soil while still remaining connected to the root. This extraradical mycelium provides the plant with water and nutrients especially phosphorous that would otherwise remain inaccessible to roots. | Efficiency of mycorrhizal fungi with different levels of phosphatic fertilizer on growth of Piper mullesua plantlets
