Abstract
In order to Study effects of drought stress and potassium fertilizer on quantities and qualities of Ammi(Carum Copticum) a field experiment was conducted-using split plot design with three replication in research farm station, Zabol university, Zabol, Iran at cropping season 2011. Treatments included application of three irrigation regimes (4, 6 and 8 days intervals), as main plots and four level of potassium fertilizer (0, 75, 150 and 225 kg/h) as sub plots. The statistical analysis showed that drought stress had significant effect on quantity characteristics plant, such plant height, number of flower per plant, seed yield and biological yield, and decrees them. In this study, drought stress led to increased essential oil percentage, but the greatest essential oil percentage and oil yield obtained when irrigation regimes 6 days intervals. Using of potassium fertilizer increased quality characteristic plant and using 225 kg/h potassium fertilizer increase seed yield. The positive effect of potassium fertilizer on essential oil percentage and essential oil yield observed maximum to 225 kg/h.
