The vital response of the corn Zea mays L. to Foliar Application with Arginine and licorice extract

Abstract

The field experiment was conducted in Anbar Governorate during the 2019 spring season to study the effect of three levels of arginine acid 0, 50 and 100 mg sprayed on the leaves and sprayed with licorice extract at concentrations 0, 1000, 2000 mg L. The experiment was carried out according to the split-plot system using the RCBD design with three replicates. The significance of the differences between the averages of the studied traits was tested according to anLSD test at a probability level of 0.5. The study showed the superiority of plants sprayed with Arginine at the higherrate for all the studied traits (plant height, Percentage of seeds protein (%), Weight of 300 seeds (Gm.) andThe Leaf Chlorophyll content (mg^-1)), as for the effect of spraying treatments with licorice extract, all sprayed plants outperformed withthe higherrate for all studied traits compared to the control treatments. Interaction treatments between arginine acid and licorice extract showed the higherrate for all studied traits compared to the control treatments.
