In experiment which was established in four repetition, we researched the influence of various row spacing (40, 50, 60 and 70 cm - factor A) and two varieties (factor B) on the flowers production and petals yield of pot marigold, and also we determined percentage of petals in totally mass of flowers. Investigation was managed on experimental field in Research institute of field and vegetable crops, on Rimski Šančevi, Novi Sad, Serbia. In average, variety Bački Petrovac was realized higher flowers yield in relation to variety Plamen Plus, for 1061 kgha -1 . In average for both varieties, maximum mass of flowers (5379 kgha -1 ) was realized at 40 cm row spacing. Mass of petals at tested variety, in average for all four row spacing was not significantly different. Petals allotment in totally mass of flowers in average for all row spacing at variety Bački Petrovac was 33,58 %, and it was lower in relation to variety Plamen Plus, in average for 7,53 %.
