EFFECT OF FOLIAR APPLICATION WITH KT-30 AND ACTIVE DRY YEAST IN GROWTH AND CHEMICAL CONTENT OF NAGAMI KUMQUAT (FORTUNELLA MARGARITA SWINGLE) SAPLINGS

Abstract

Abstract: The experiment was carried out in the lath house of Horticulture and Landscape Gardening Department, College of Agriculture, University of Anbar, Iraq, during the 2020 growing season, on three-year-old nagami kumquat saplings to study the effect of foliar spraying with KT-30 at four concentrations (0 and 2, 4 and 8 mg.L-1), active dry yeast at three levels (0, 0.4 and 0.8%) and their interactions in some vegetative growth traits and chemical content. The results indicated that the two study factors showed a significant effect in all of the studied characteristics especially the foliar application treatment of KT- 30 at a concentration of 8 mg.L-1 and the spraying with dry yeast at a level of 0.8% where achieved a significant superiority in the number and length of secondary shoots increment, leaves number increment, leaves area, percentage of nitrogen, phosphorus, potassium in leaves and their total chlorophyll content compared to the control treatment which achieved the lowest values. Bilateral interference treatments had a significant effect on all of the studied traits especially K3XY2 treatment.
