The goal of this research was to determine how different dosage use of nitrogen (N) affects the overall number, mass and diameter of Marigold flowers. According to the primary hypothesis, increased amounts of mineral fertilizers have negative effects on Marigold flower production. Monofactorial experiment was executed using the random block system with four repetitions, at the 2m2 experimental parcel site. In this experiment we used the NPK fertilizer with formulation (7:20:30) and nitrogen fertilizer KAN. Based on the sample of 10 flowers we applied and tested the both types of fertilizers and analyzed the : whole-plant mass, height of plant, number of flowers per plant and diameter of inflorescence. Cilj ovih istraživanja bio je da se utvrdi efekat djelovanja različitih doza azota na broj, masu i prečnik cvjetova nevena. Osnovna hipoteza od koje se polazi jeste da povećana količina mineralnih đubriva utiče negativno na produkciju cvjetova nevena. Monofaktorijalni ogled postavljen je po slučajnom blok sistemu u 4 ponavljanja sa veličinom obračunske parcele od 2m2. U ogledu smo koristili NPK đubrivo formulacije (7:20:30) i azotno đubrivo KAN. Na uzorku od 10 biljaka svake varijante đubriva analizirali smo : masu cijele biljke , visinu biljke , broj cvjetova po biljci i prečnik cvasti.
