In order to investigate the effect of nitrogen fertilizer and zinc sulfate sources on Calendulaofficinalis plant yield, a factorial experiment was conducted in a randomized complete block design with three replications at 2011. Experimental factors included nitrogen fertilizer sources (manure and urea fertilizer) with 4 levels, 0 tons of manure + 120 kg urea, 10 tons of manure + 90 kg urea, 20 tons of manure + 60 kg urea, 30 tons of manure + 30 kg urea and 40 tons of manure + 0 kg urea and zinc sulfate with 3 levels, no foliar application, 1 foliar application and 2 foliar application times were recommended. Results showed that different sources of urea fertilizer were applied on capitol diameter. Number of seeds per plant and flower harvest index had a significant effect, but no significant effect on grain harvest index. The plant represents a significant effect on harvest index and harvest index put Dada, but had no significant effect also results indicated that the interaction between different sources of nitrogen and sulfate on the number of seeds per plant were significant.
