Abstract

In order to investigate the effects of biofertilizer on essential oil harvest index and productivity effort of black cumin (Nigella sativa L), an experiment was conducted during the growing season of 2010 at Iran. The experimental design was factorial on the basis of randomized complete block design with three replications. Certain factors including four levels of animal manure (0, 10, 20 and 30 ton/ha, respectively) and two levels of azotobacter (non-application and application) were studied. The final statistical analysis indicated that in the 10 ton/ha animal manure and azotobacter application, essential oil, harvest index and productivity effort were significantly higher.

Key words: Biofertilizer, essential oil, Nigella sativa, harvest index.
