Abstract:

The effects of organic and chemical fertilizer on essential oil yield and yield components of fennel (Foeniculum vulgare) in drought conditions at greenhouse pot experiment in 2013 were examined as a factorial design with three replications. Treatments wer three levels of stress (irrigation after 50%, 70% and 100% water consumption as main plot and addition of chemical fertilizer (20 g), manure (10 g), compost (10 g) and control (no fertilizer) as sub plot. Results showed that increasing of stress increased essential oil content, however, the effect of drought stress on grain yield and essential oil yield was decreasing. In addition the results showed that effect of chemical fertilizers treatment on grain yield and essential oil was significant at1% level. Comparison showed that the compost used is optimal conditions; irrigation highest oil yield as much as 192 g per pot to produce this result is due to higher yield rate of 7.2.
