Sweet basil (Ocimum basilicum L.) is an annual plant belonging to the plant family Lamiaceae. There are many varieties of basil, with leaves of colour from green to purple and with small white or pink flower. In field experiment conducted in the year 2020 - 2021 at Medicinal and Aromatic Plants Research Station, Rajendranagar, Hyderabad. Data were recorded on growth parameters like plant height, number of branches per plant, leaf area, yield parameter on fresh yield per hectare, seed yield per hectare and quality parameters like essential oil ratio and essential oil yield. Among the treatment combination 40 cm X 20 cm and supplied with 150:75:75 NPK kg per ha (S₁F₄) was found to record the highest plant height, fresh yield per hectare and seed yield per hectare. The widest spacing of 60 cm x 40 cm and supplied with 150:75:75 NPK Kg per ha (S₃F₄) recorded the maximum number of branches per plant and leaf area. Quality parameters like essential oil ratio and essential oil yield shows non-significant effect with NPK applications and plant spacing.
