Abstract
Cumin is one the most important medicinal plant in Iran. A field experiment was conducted in order to evaluate the effect of compost (30t/ha), Vermicompost (10t/ha), cow manure (30t/ha) and sheep manure (20t/ha) and control (no fertilizer) on yield and yield components of Cumin. The experiment was performed in the research farm of Faculty of Agriculture, Ferdowsi University of Mashhad during the growing season of 2007. A randomized complete block design with 5 treatments and 3 replications was used. Results showed that treatments had a significant effect on grain yield and biological yield, number of umbers per plant, number of seed per umber, number of seed per plant and plant height. The treatments had no significant effect on HI (Harvest index) and 1000 seed weight. The highest and the lowest seed yield, biological yield and plant height were obtained in Vermicompost and control, respectively. The present study showed that organic fertilizers and animal manures can enhanced the yield and its components in Cumin.

Abstract
Biofertilizers are one of the main sources to supply nutrient elements for plants in sustainable agriculture. In order to evaluate the effects of biofertilizers and chemical fertilizers on Cumin (Cuminum cyminum) as a medicinal plant a field experiment was conducted in the Research Farm of Faculty of Agriculture, Ferdowsi University of Mashhad in a randomized complete block design with three replications in year 2008.The treatments were nitrogen fixation bacteria (Azotobacter and Azospirillium) and phosphate solublizing bacteria (Pseudomonas flurescence) in pure and combination treatments and chemical fertilizers treatment compared with control treatment. The result indicated that performed treatments could significantly enhance the yield and yield components. Biofertilizers increased the biological yield, seed yield, plant height, number of umbers per plant, number of seed per umber, number of seed per plant and the thousand seed weight. Combination use of Azotobacter and Azospirillium with pseudomonas had better effect on most of the studied characteristics compared with other treatments. In general, biofertilizers could be a good substitution for chemical fertilizers in cumin production.
