For evaluation of different sowing times and plant densities effects on marigold, a factorial experiment with randomized complete block design and three replications was carried out at the Research Farm of the Faculty of Agriculture, University of Tabriz, Iran. Three sowing times (May 10, May 26 and June 10) and four plant densities (30, 40, 50 and 60 plants/m2) were studied. The analysis of variances showed that sowing time and plant density have significant effects on leaf number, plant height, plant dry weight and flower dry weight. However, the interaction of sowing time and plant density has not any significant effect on evaluated traits. The results showed that 60 and 30 plant/m2 density produced the highest and lowest flower dry yield, respectively. In conclusion, this study showed that sowing at May 26 and 60 plant/m2 is suitable for producing the highest flower yield of marigold at Tabriz climate conditions.
