English. Experiment with pot marigold (Calendula officinalis) used as a stubble crop was performed on organic field at the Bački Petrovac (Serbia) location. Twelve harvests were accomplished during a period of 60 flowering days. The measurements included plant height, weight of inflorescences per individual harvest and total weight and inflorescence diameter. Coefficients of variation and correlation were calculated for the above traits. Differences in variation coefficients between the analysed traits, relying upon harvest date, were recorded. According to the obtained results, harvest date had a higher impact on total carotenoid content and inflorescences yield than on plant height and inflorescence diameter. Highly significant positive correlation was found between the mass and number of inflorescences. stubble

Tokom 60 dana cvetanja ostvareno je 12 berbi. Merena je visina biljaka, masa cvasti iz svake berbe, ukupna masa cvasti, kao i prečnik cvasti. Izračunati su koeficijenti varijacije i korelacije. U zavisnosti od vremena berbe zabeležene su razlike u koeficijentima varijacije za ispitivane osobine. Prema dobijenim rezultatima uticaj vremena berbe bio je izraženiji na sadržaj ukupnih karotenoida i prinos cvasti nego na visinu biljke i prečnik cvasti. Masa i broj cvasti bili su u visoko značajnoj pozitivnoj korelaciji.
