Arbusculer mycorrizal fungal investigation in the weeds of wheat field of Tehsil Tangi, District Charsadda, Khyber Pakhtunkhwa.
An investigation has been make about the Arbuscular Mycorrhizal Fungi (AMF) spore density in weeds plants with soil selected from the Tehsil Tangi. The spore density was observed in all weeds plants in the host growth stage. The maximum Arbuscular Mycorrhizal Fungi (AMF) spore density wasfound in Chenopodium album (93.00±74.02) and Scandix iberica (89.00±92.08) at vegetative stage. The Glomus species are dominant in the rhizosporic soil of weeds plants followed in Aculospora, and Sclerocystis. The lowest Glomus spore density are present in Fumariapureflora (10.67±15.89).The spore density of AMF had a strong positive correlation with soil PH and carbon is negative correlation with P content of the soil. Thehighest Vesicles are investigated in.Euphorbia heliscopia(14.33±9.5) and lowest in Circium arevesis (3.33±1.53) .Arbuscules was higher in Euphorbia heliscopia (18.67±18.72) and lowest in Circium arvensis (2.00±1.73). Highest External hyphae was found in Silene conidia (4.00±1.73) and lowest in Anagallus arrensis. Internal hyphae were in Rananculas maricates (6.33±5.13) and lowest in Melolotus indica(0.67±0.58). While totally absent in Brassica nigra (Brassicaece).
