EFFECT OF GROUND FERTILIZATION WITH HUMIC ACID AND SPRAYING WITH SEAWEED EXTRACT AND BAKING YEAST AND THEIR EFFECT ON THE BUKTHORN TAFAHE SEEDLING

Abstract

Experiment was conducted in the wooden canopy of the Department of Horticulture - College of Agriculture - Anbar University during the beginning of 2023 on three-year-old Sidr seedlings to determine the effect of humic acid H0, H1 at two concentrations of 0.10 g l-1 and spraying with algae extract A0, A1, A2 at three concentrations of 0. 1, 1.5 g L-1 and baking yeast Y0, Y1, Y2 at three concentrations 0, 10, 20 g L-1 and their interactions. The results showed the superiority of the H1 treatment by recording the highest rate of increase in seedling height (cm), number of leaves (seedling leaf-1), leaf area (cm2), percentage of nitrogen and total protein in leaves (%) and chlorophyll content of leaves (mg 100 g weight Soft) compared to the comparison treatment that gave the lowest values. Regarding foliar feeding with seaweed extract, treatment A2 was significantly superior to the other by giving the highest rates and percentages, while comparison A0 gave the lowest rates and percentages. As for spraying with yeast, treatment Y2 excelled by giving the highest values for the studied traits, while the comparison treatment Y0 recorded the lowest values. As for the bilateral interaction between the study factors, the H1A2, H1Y2, and A2Y2 outperformed the other treatments for most of the studied traits, except for the leaves area treatment, A1Y2, which significantly outperformed all other treatments.
