In: Mansoura University Journal of Agricultural Sciences 2009.v.34(4)Part BSummary: A pot experiment was carried out in the season of 2006 under the green house of EI-Mansoura Laboratory for Plant Nutrition. Soil, Water and Environment Institute to study the effect of different N forms (ammonium nitrate, ammonium sulphate and urea) and doses (30. 45 & 60 kg N/fed) as well as the effect of foliar application of Fe. Mo & Mn on growth and mineral composition of radish and parsley plants. The results revealed that using ammonium nitrate as a source of N fertilizer recorded the highest value of plant height followed by ammonium SUlphate and urea. The height of radish and parsley plants was significantly increased as the level of nitrogen fertilizer increased. The fresh and dry weights were significantly increased up to 60 kg N level. Foliar application of Fe. Mn and Mo as solely or in mixture significantly increased the values of fresh and dry weights compared to the contro·1. Increasing the level of N fertilizer from 0 to 60 kg N/fed high significantly increased the concentration of Nand K, while P concentration was insignificantly affected. Concentration of N or K was significantly increased due to micronutrients application, while P was insignificantly affected. Micronutrients (Fe, Mo and Mn) were gradually and significantly increased as the level of N fertilizer was increased up to 45 kg level of N fertilization.
