Abstract:
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. In the present study, Piper mullesua seedlings were infected with ten different strains of AM fungi and one without inoculation of AM fungi under three levels of phosphatic fertilizer (superphosphate). Shoot length, plant biomass, phosphatase enzyme activity, concentration of P and N of AM infected plants were found higher than those of non-mycorrhizal controls, which confirms the contribution of AM fungi. In our experiment it has been found that mycorrhizal fungal isolates G. etinucatum (0.887gm ±0.033), G. claroidium (0.861gm ±0.023) and G. aggregatum (0.859gm ±0.016) performed significantly (p>0.001, F=14.14) higher in improving plant biomass of Piper mullesua seedlings at lower dose of super phosphate which confirms higher efficiency of mycorrhizal fungi with reduced dose of phosphatic fertilizer.
