| Abstract | ||||
| AN EXPERIMENT was conducted to study the effect of some foliar spray treatments on yellow rust and leaf rust severities, productivity, and grain quality of wheat cultivar “Gemmiza-7”. The treatments: hydrogen peroxide (H2O2) 30% (1mM), nano CaCO3 0.5% (5.0g/L), combination of H2O2 30% (1.0mM), and nano CaCO3 0.5% (5.0g/L), KCl (5.0g/L) and fungicide Tilt 25% EC (Propiconazole) at 25mL/100 liter- were applied with the control treatment (spraying with water). Results indicated that, all treatments had a significant effect on all the studied parameters, hence reduced rust disease infection and increased 1000 kernel weight, grain, straw, and biological yield of wheat, mineral uptake by wheat plants and total protein in grains compared with the untreated control. Spraying with the fungicide recorded the most effective treatment in reducing the yellow and leaf rusts severity in both seasons, followed by spraying with H2O2 30% which gave a disease control of (55.00 and 54.54%) for yellow rust and (74.08 and 70.57%) for leaf rust in the 1st and 2nd seasons, respectively. Spraying plants with H2O2 30% + nano CaCO3 0.5% after 70 and 100 days from sowing recorded the tallest plants and maximum values of shoot dry weight/plant, root dry weight/plant and flag leaf area. Significant increase in the concentrations of chlorophyll a, b and total chlorophyll in leaf tissues was observed. Increase in mineral contents and uptake by wheat plants without significant differences with nano CaCO3 at 0.5% and KCl at 0.5% was also recorded. | ||||
