Study area of Naldurg is located at 17.82EN 76.3EE in Osmanabad district of Marathwada region in Maharashtra state. This area lacks natural resources and is prone to drought, rocky and dry with low and uncertain rainfall, therefore the
objectives of this study was to ascertain the status of AM fungi in weeds growing on barren and degraded land and their use in agriculture during both rabi and kharif season. Degraded land fields weedy plant species of roots were collected in rabi and kharif season during 2015-2016.Three each plant species were selected for assessment of AMF root colonization, spore density and spore diversity was calculated from every sample collected of weedy plants species. Altogether 21 species belonging to 11 families and 21 genera in rabi season and 20 weedy plant species belonging to 9 families and 20 genera in kharif season were collected from degraded field and examined diversity and Arbuscular Mycorrhizal Fungi (AMF) status. Percent AMF root colonization ranged from
40.62-84.37%. The highest colonization was recorded in Phyllanthus niruri (84.37%) and least in Cocculus hirsutus (40.62%) in rabi season. In case of kharif, percent root colonization ranged from 43.75-81%.The highest colonization was recorded in Dichanthium caricosum (81%) and least in Adenostemum alavenia (40.62%). Vesicular, arbuscular and hyphal types of root colonization was recorded in both
season. Seven of the 11 common plant species showed higher root colonization in rabi season as compared to kharif. AM fungal spore density varied in all weedy plant species and ranged from112-1168 spores/100 g soil in rabi while237-702/100g soil kharif season. A total
of three AM genera viz., Acaulospora, Glomus and Scutellospora were recorded in both the season. In seasonal variation, AM spore density was greater in the rabi season than kharif. A positive correlation was found between AM root plants. There were significant differences between the organic and conventional systems in the density and biomass of both non-competitive weeds and competitive weeds. |
