Abstract
A field experiment was carried out for one of the fields in Al-Qadisiyah Governorate / Al-Shafi’iyah district, where the soil texture of the field was (Sandy loam) in order to study (the effect of fungal inoculation, cow manure and dab manure on the growth of wheat plants and the readiness of iron and zinc in the soil), which was planted in the winter season 2021/2022 and the experiment contained three factors, the fungal inoculation (G. mosseae) was at two levels (and no Addition G0, AdditionG1), cow manure at three levels (0-1-2) tons, ha, and dab manure three levels (0-50-100%). All results had significant differences, as when inoculating with (G. mosseae) the treatment (G1) was superior in plant height, chlorophyll, iron and zinc, which averaged (89.446) cm, (44,905) SPAD, (9.739) mg Fekg−1 Soil, (0.340) mg Zn kg −1 soil, while when fertilizing with cow waste, where treatment (P1) was superior in plant height, chlorophyll and iron, while zinc was superior to treatment (P2), (92.083) cm, (46.226) SPAD and (10).850 mg Fe kg −1 soil, (0.347) mg Zn kg −1 soil, while the mineral fertilizer, where treatment (D2) was superior in plant height, chlorophyll and zinc except for iron, where treatment (D1) was superior to (88.640) cm, (45.292) SPAD and (0.339)) mg Zn kg −1 soil, (9.871) mg Fe kg −1 soil, while the bilateral interaction between (G. mosseae) and mineral fertilizer, where the treatment (G1D2) excelled in all characteristics, which averaged (91,444) cm, (46,509) SPAD and (10.416) mg Fe kg −1 soil, (0.344) mg Zn kg 1 soil, while the interaction between cow manure and mineral manure, where the treatment (P1D) was superior in plant height, chlorophyll and iron except zinc, (94.137) cm, (48.418) SPAD and (11.552)) mg Fe kg −1 soil, (0.349) mg Zn kg −1 soil,871) mg Fe kg −1 soil, while the bilateral interaction between (G. mosseae) and mineral fertilizer, where the treatment (G1D2) excelled in all characteristics, which averaged (91,444) cm, (46.509) SPAD and (10,416) mg Fe kg −1 soil, (0.344) mg Zn kg −1 soil, while the interaction between cow manure and mineral manure, where the treatment (P1D) was superior in plant height, chlorophyll and iron except zinc, (94.137) cm, (48.418) SPAD and (11.552) mg Fe kg −1 soil, (0.349)) mg Zn kg −1 soil,871) mg Fe kg −1 soil, while the bilateral interaction between (G. mosseae) and mineral fertilizer, where the treatment (G1D2) excelled in all characteristics, which averaged (91,444) cm, (46.509) SPAD and (10,416) mg Fe kg −1 soil, (0.344) mg Zn kg −1 soil, while the interaction between cow manure and mineral manure, where the treatment (P1D) was superior in plant height, chlorophyll and iron except zinc, (94.137) cm, (48.418) SPAD and (11.552) mg Fe kg −1 soil, (0.349)) mg Zn kg −1 soil. As for the triple intervention, where the treatment outperformed (G1P1D2) in plant height, chlorophyll and iron except zinc, where the treatment (G1P2D2), (94.633) cm, (51.547) SPAD, (12.543) mg Fe kg −1 soil and (0.352) mg Zn kg −1 soil were superior.
