Abstract :

In order to investigate the effects of vermicompost and urea chemical fertilizers on nitrogen, phosphorus and potassium uptake in marshmallow (Altheae officinalis L.) organs, a field experiment was conducted at Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, in years of 2012. Experiment was conducted using a completely randomized block design based on factorial arrangement with three replications. Experimental treatments were three levels of vermicompost (0, 5 and 10 t. ha-1) and five levels of urea fertilizer (0, 25, 50, 75 and 100% of 200 kg N ha-1). Irrespective of urea fertilizer, vermicompost application had an effective role on increasing nitrogen, phosphorus and potassium percentages in seed, leaf and root of marshmallow. By applying 10 t vermicompost ha-1, phosphorus percentage in seed of marshmallow was increased by 29.5 %, as compared to control treatment. Nitrogen, phosphorus and potassium contents in seed, leaf and root of marshmallow (g. m-2) were significantly increased by vermicompost application. From the results, urea fertilizer caused a significant increase on nitrogen, phosphorus and potassium percentages in seed, leaf and root of marshmallow. According to the results, there was a positive relationship between nitrogen uptake with phosphorus and potassium uptake.
