COMPARATIVE STUDY OF LOCAL ARBUSCULAR MYCORRHIZAL FUNGAL SPORECONTAINING SOIL ON THE YIELD OF MANGO GINGER

Abstract

Most of the terrestrial plant species are being infected by a large number of mycorrhizal fungi either ecto-mycorrhizae or endo-mycorrhizae. Different types of endo-mycorrhizae are present within the roots of herbaceous plants and arbuscular mycorrhizae (AM) are predominant within them. AM fungi play a vital role in symbiosis either in field condition or in experimental condition. In nature, rhizosphere soil of forest, degraded land, agricultural land and fallow land contain a good and diverse number of AM fungal spores throughout the year, though winter shows highest number of spore density. Application of chemical fertilizers and pesticides decrease the number of AM fungi in the soil hence deteriorates the quality of the soil as well as soil health. It is evident that soil inhabiting AM fungi enhance the growth and yield of plants and helps to combat with different pathogen infection and stresses. The rhizosphere soil with natural vegetation is a good repository of AM spores though agricultural land with huge application of chemical fertilizers and pesticides shows less number of AM sores. In this communication different forest soils, anthill soil, agricultural land soils and degraded land soil inhabiting AM spores were inoculated on Mango Ginger rhizome and the yield have been presented. Result showed anthill is a good repository of vivid AM spores in compare to other sites.
