Effect of Different concentrations (NPK) on Growth and Flowering of (Helichrysumbracteatum)

ABSTRACT:StudyDifferent Levels Nitrogen and Phosphorus on Growth and Flowering of (Helichrysumbracteatum) flower an experiment was conducted in completely randomized design in eight replication and fourtreatmentatAgriculturalTechnical Institute of Bakrajo-Sulaymaniah Polytechnic University-Kurdistan-Iraq, during growing season of 2011-2012, to study the influence of different concentrations (0.0,0.5,0.7,1 gm/plant) of soil fertilizer nitrogen, potassium and phosphorus contains (5%N, 30%P2O5, 0%k2O) on the growth and flowering of (Helichrysumbracteatum) The soil fertilizer was applied 3 times during the growing period. Analyses of variance (Table 1) showed that the effect of NPK was significant on number of branch and number of leaves, number of flowers, flowers diameter, number of flowers buds remain of Helichrysumbracteatum. Correlation analysis showed number of leaves had the highest positive and significant correlation with plant height (0.604) followed by number of flowers and flowers diameter (0.562).
