Abstract :

In order to study the effects of drought stress and biofertilizers (Humic acid, compost and manure) on quantity and quality characteristics of basil (Ocium basilicum) a field experimental was conducted in split plot design with three replications in 2012 at University of Zabol research farm. Drought stress treatments included: [S.sub.1]: control (100% FC), [S.sub.2]: moderate stress (80% FC) and [S.sub.3]: sever e stress (60% FC) as the main plot and application of biofertilizer: [N.sub.1]: 4 0 ton compost [ha.sup.-1], [N.sub.2]: 40 ton manure [ha.sup.-1], [N.sub.3]: 6 liter of humic acid per hectar as sub plot. Results indicated that the drought stress had significant impact on dry weight of basil and decreased it compared with the control. The greatest yield (886.5 kg/ha) and other morphologic characteristics (leaf number, plant height, stem diameter, number of lateral branch) were obtained in no stress along with application of 4 0 ton compost [ha.sup.-1]. Essential oil content increased with increasing drought stress severity. This study suggests due to increasing essential oil content at the 80% FC, the cultivation of basil at the 80% FC together with application of compost at Zabol condition is suitable. Key words: Drought stress, humic acid, compost, manure, sweet basilicum
