How land preparation is done for growing Holy Basil?

The main planting field should be prepared with drainage channels between rows. The soil should be given couple of ploughings and harrowings till it attains the fine tilth stage.  Level the field and mix well decomposed farm yard manure of 15 to 20 tons/ha (basal dose) like cow dung at the time of last plough. Once the fine seedbeds are prepared in the field, land will be ready for Tulsi transplantation.
