Abstract
This experiment was carried out at the field of botanical garden which belongs to Biology Department , College of Education (Ibn Al-Haitham), University of Baghdad during the growing season 2009-2010.The experiment was designed to study the effect sex concentrations of Gibberellic acid(GA3)( 0, 25,50,75,100and125mg.L-1 ) and three levels of NPK (17:17:17) fertilizer ( 0 , 200 and 400 Kg.ha-1) and their interaction on the some macronutrients ( N, P , K , Ca and Mg ) concentration in two varieties of chamomile plant ( Local variety , Matricaria chamomilla L. and German variety , Matricaria recutitia L.) . Randomized complete block design (RCBD) with split – plots arrangement was used with 3 replicate for each treatment. results showed a significant increase in the concentration of macronutrients with increased GA3 concentration and NPK levels and their interaction in comparision with the control plants . The highest rates of macronutrient concentrations were obtained by using GA3 at 75 mg.L-1 and NPK at 400 Kg.ha-1 . The German variety surpassed the Local variety .
