Abstract
Parsley has a very high nutritional value, containing A, B and C vitamins and mineral nutrients. In order to investigation of the effect of different nitrogen sources on parsley an experiment conducted in a factorial combination of three nitrogen forms (calcium nitrate, ammonium sulphate and urea) and four nitrogen levels (0, 100, 125, 150 kg ha-1) by using a factorial experiment based on randomized complete block design with three replications. The results showed that the effect of nitrogen sources was significant on all measured parameters. As the highest shoot fresh weight, root fresh weight, vitamin C and leaf Ca concentration obtained at 150 kg ha-1 of calcium nitrate and the highest shoot dry weight, plant height, leaf length and leaf iron concentration at 150 kg ha-1 of ammonium sulphate and the highest amount of chlorophyll a+b at 150 kg ha-1 of urea.
