Experiment was conducted during two successive seasons 2012-2013 to study the effect of growing media on growth and oil production in greenhouse or in open field. Available soil (loam soil) from El-Bosaily Research Station was blended with (20, 40, 60 and 80% blends in volume of peatmoss) beside a 100% loamy soil. Other 6 growing media were prepared consist of 10, 20 or 30% of compost or vermicompost with loamy soil. Basil dry weight, plant height, chlorophyll and essential oil percentage and yield were measured. Compost application in the growing media enhanced plant height, dry herb and oil contents. Compost uses in growing media enhanced plant growth performance as compared with peat-moss or mixed media with vermicompost. Plants grown in compost showed 2-3 times greater shoot number than the other treatments. Different peat-moss media mixture and control showed notable reduction in chlorophyll content as compared with mixed media containing compost or vermicompost. The number of lateral stems increased (up to 2-4 times) in basil when compost added into substrate mixtures as compared to lowest value in both seasons and cuts.
