In order to study the effects of drought stress and three types of fertilizers on quantitative and qualitative characteristics on Basil (Ocimum basilicum L.) a greenhouse experiment in a factorial under randomize complete block design with three replications was conducted in 2011 at University of Zabol. Treatments included: Irrigation at three levels 100% (control), 80% FC and 60% FC and fertilizer treatments included non-fertilizer, chemical fertilizer, manure and compost (25 tons per hectare). In this study, drought stress led to increased essential oil percentage, whereas the greatest essential oil percentage obtained when 60% FC was applied. Increasing drought stress decreased the amount of dry yield, dry weight per plant, plant height, subshrub and internode number. Among fertilizers, chemical fertilizer had the highest effect on essential oil content. Results showed that Basil maximum essential oil content could be achieved applying 60% FC levels. Moreover, using manure fertilizer under high level of drought stress was more effective.

In order to study the effects of drought stress and three types of fertilizers on quantitative and qualitative characteristics on Basil (Ocimum basilicum L.) a greenhouse experiment in a factorial under randomize complete block design with three replications was conducted in 2011 at University of Zabol. Treatments included: Irrigation at three levels 100% (control), 80% FC and 60% FC and fertilizer treatments included non-fertilizer, chemical fertilizer, manure and compost (25 tons per hectare). In this study, drought stress led to increased essential oil percentage, whereas the greatest essential oil percentage obtained when 60% FC was applied. Increasing drought stress decreased the amount of dry yield, dry weight per plant, plant height, subshrub and internode number. Among fertilizers, chemical fertilizer had the highest effect on essential oil content. Results showed that Basil maximum essential oil content could be achieved applying 60% FC levels. Moreover, using manure fertilizer under high level of drought stress was more effective.
