In this paper, the effects of usage of different fertilization amounts on fresh iris rhizome yield were presented. As the other factor of this experiment, the two ways of growing: dry cultivation and drip irrigation were investigated. Researches were conducted on marsh dark soil on the experimental field of Institute for Medicinal Plant Research Dr Josif Pancic in Pancevo (Serbia). Experiment was set up by method of completely random block system in four repetitions and the size of basic parcel was 10 square meter. In this trial there was 3 variants of fertilizations (200 kg/ha NPK 15:15:15, 400 kg/ha and 600 kg/ha) comparing to control parcel which had not been fertilized. The highest fresh iris rhizome yield was obtained with variant of 600 kg/ha and the lowest was on the control parcels. All variants of fertilization which were watered by drip irrigation had considerable higher yields then variants with dry cultivation.
