Abstract

To assess the impact of potassium and different forms of nitrogen on antioxidant enzyme activity and physiological changes in wheat affected by Fusarium head blight (FHB), we conducted a factorial experiment using a completely randomized design with three replications. The treatments comprised two disease levels (Control and infected), three potassium levels (80, 100, and 120 kg.ha-1), and three nitrogen application styles (ammonium sulfate, calcium nitrate, and a compound treatment consisting of 75% calcium nitrate + 25% ammonium sulfate). The results revealed an increase in the levels of superoxide dismutase (SOD), and putrescine under FHB, particularly with the application of potassium and nitrate. However, protein yield decreased under FHB disease, especially with the use of ammonium; in contrast, potassium and nitrate application led to an increase in protein yield. The methionine content decreased under disease conditions. The Fusarium head blight of wheat enhanced antioxidant enzyme activity. The application of potassium and nitrate exhibited a more significant impact on mitigating the adverse effects of the disease compared to potassium alone. This effect could be attributed to their ability to reduce osmolyte levels and modulate the activity of antioxidant enzymes.
