The Effect of Inoculation Mycorrhiza and Organic Fertilizer and Dab Fertilizer in the Availability NPK for Local Wheat (Triticum aestivum L. )

A field experiment was carried out in one of the fields of Al-Qadisiyah Governorate, Al-Shafi`iyah district, for the season 2021/2022 using soil (Sandy loam) to study the effect of inoculation mycorrhizal, organic fertilizer and dab fertilizer on Availability NPK of local wheat plants (RCBD) design. The experiment included three factors of inoculation mycorrhizal (G0, G1) and organic fertilizer (0-1-2) tons. ha, and mineral fertilizer (0-50%-100%) and the lsd test was calculation the least significant difference at the 0.05 level, where it showed that there is a significant effect and the superiority of the treatment inoculated with Mycorrhizal fungus on the comparison treatment in nitrogen, phosphorous, potassium, and the average reached (2.229%),( 0.298%), (1.475%), as well as the treatment of organic fertilizer (P2) over the control treatment (P0) in nitrogen (2.313%) and the superiority of treatment (P1) in phosphorous (0.321%), and the treatment (P2) in potassium (1.493%). The treatment of mineral fertilizer at the level of 50% was superior in nitrogen, which amounted to (2.116%), and in phosphorous, the treatment exceeded 100% (D2), where it reached an average of (0.310%), and in potassium, the treatment exceeded 100% (D2) (1.478%), while in The case of binary interference between G.
