A doctoral thesis at the College of Agriculture at Al-Qadisiyah University discussed the effect of adding nano-magnetic iron suspension, carbon nanotubes, and bio-stimulants on the growth and yield of Agaricus bisporus fungus.


The doctoral thesis entitled “The Effect of Adding Magnetic Iron Oxide Suspension, Carbon Nanotubes, and Biostimulants on the Growth and Yield of Agaricus bisporus” was discussed at the College of Agriculture at Al-Qadisiyah University. The thesis was presented by Mustafa Abdul-Sada Hassan, under the supervision of Professor Dr. Hayawi Waheed Attia Al-Jawdhari and Professor Dr. Raqiba Ali Jijan. The study aimed to determine the effect of adding magnetic iron oxide suspension (N-FeO), carbon nanotubes (CNTs), liquid EM biofertilizer, and Atonik growth stimulant as single additives and in binary, triple, and quadruple combinations on some growth parameters and the quality of A. bisporus mushroom yield. The most important recommendations, based on the results obtained from this study, are to support the growing medium and mycelium by spraying liquid EM biostimulant (100 ml L-1) and Atonik growth stimulant (0.5 ml L-1). This resulted in the highest quantitative and quality indicators of A. bisporus mushroom yield.
