Study of Different AM Fungi and Soil Moisture Levels on Component of Yield of Grass

In order to determination of different levels AM fungi and soil moisture on the quantitative and qualitative grass yield, an investigation with three levels of moisture and four level AM fungi in three replication using randomized completely block design was done. This research was achieved in payame noor University, Marivan, Iran. Results from the analysis of variance showed that highly significant difference existing among all traits measured. thus indicating that there is variability in traits studied. Results correlation analysis showed that was high significant and positive correlation with all studied traits. The highest positive correlation in moisture condition were observed between Dry weight of root and Turgid weight of air organ (r = 0.992**). Results correlation analysis in species AM fungi showed Fresh weight of air organ and Turgid weight of air organ (r = .987**), Packed root and Fresh weight of air organ and Turgid weight of air organ & Dry weight of root (r = .986**) Dry weight of root and Fresh weight of air organ (r = .975**).
