Abstract
The present investigations focus the AMF (arbuscular mycorrhizal fungi) flora in maize and wheat fields in different study areas of Khyber Pukhtunkhwa (KP), Pakistan and describe their interdependency with various physico-chemical features of soil due to AMF has potentiality as a fertilizer. In this study, the soil samples were amassed along-with roots for determining the AMF spores and their densities per 100g of soil. The roots were stained and estimation of Root Endomycorrhizal Colonization (REC) index was withal determined. Eleven AMF species in the wheat fields and seven in maize lands were revealed, among them the ascendant genus was Glomus (10 species) followed by Sclerocystis and Acaulospora. The density of the accumulated AMF spores from the different regions ranges from 80-194/10g of soil. Coefficient of correlation (r) was estimated statistically to ascertain the relationship between AMF spore densities and the chemical characteristics of soils. This investigation concludes that the accessibility of AMF increases the productiveness of wheat and maize yields and these spores are consummately or pessimistically correlated with chemical characteristics of the soil in the investigated zones.
