Calendula officinalis L., herbaceous and permanent plant, belongs to Asteraceae family. Aerial stem is raised, branched and covered with node naps. Its flower is yellowish. To investigate the effect of sowing date, plant density and interaction effect of them on pot marigold yield, a split- plot experiment was conducted on the basis of completely randomized blocks design with 4 replicates in Research Greenhouses of Eghtesad Keshavarzi Novin Borujerd ,an economic agricultural company, in 89-90.sowing date includes? In main plot and density includes 4 levels (15, 25, 35, 45 plant.m-2) in sub-plot. Results showed that sowing date and plant density had significant (P< 5%) effect on pot marigold yield. The most and the least seed yield was related to sowing dates of February 10th and May 25th in 38.24 and 29.35 g.m-2, respectively. Among different densities, the most thousand seed weight was in density of45 plant.m-2. Results of statistical analysis showed that interaction effect of different sowing dates and plant density had non-significant effect on mentioned parameters. According to these results, density of 4 plants. m-2 and sowing date of February 10th is recommended in Borujerd climate.
