Field trial with Pot Marigold (Calendula officinalis L.) was conducted in 2008 at experimental field of Institute of Field and Vegetable Crops at Rimski Šančevi (cp 45 deg 20 N, e 19 deg 51 A,), Novi Sad, Serbia. The experimental design was a split-plot arrangement, where the main plots were cultivars and the sub-plot stand densities. There were 4 cultivars: Bački Petrovac-BP, Orange King-OK, Plamen-P and Plamen Plus-PP and 4 densities: 20, 30, 40 and 50 plants per square meter. Dry matter content of receptacle, petiole and whole flower was significantly the highest in BP and the lowest in PP. Fresh/dry ratio was in opposite position for receptacle 5.4 and 6.0, for petiole 6.4 and 7.2 and for flower 5.7 and 6.6 respectively. Plant density does not influence dry matter and fresh/dry ratio. Fresh and dry flower yield was the highest in all cultivars at density of 40 plants per square meter. There is no difference between cultivars in fresh; while in dry flower yield of BP cultivar was the highest (1,299 kg per ha) and P cultivarthe lowest (1,082 kg per ha). Fresh and dry ratio of petal/flower was the highest in PP (50 and 45%) and the lowest in P (37 and 33%). Those ratios regularly increase with increasing of stand density.
