Abstract

The present investigation entitled “Impact of biostimulants on oil yield and composition of sacred basil (Ocimum sanctum L.)” was carried out during 2021-22 & 2022-23 at College of Horticulture, Sri Konda Laxman Telangana State Horticultural University, Rajendranagar, Hyderabad. The experiment was laid out in a Factorial Randomized Block Design (FRBD) with 14 treatments, replicated thrice. The treatments include two varieties (V1 and V2) and seven biostimulants (B1, B2, B3,B4, B5, B6 and B7). The results conferred that among the treatments, maximum oil yield per plant (g/plant) (1.59, 1.65 and 1.62), Oil yield per plot (g/plot) (59.78, 62.05 and 60.91), Oil yield per hectare (Kg/ha) (99.63, 103.42 and 101.52), Quality parameters viz., Eugenol content (38.65, 40.82 and 39.74), Methyl eugenol (24.17, 25.13 and 24.65), Caryophyllene (11.63, 12.10 and 11.87) and Chlorophyll content (46.64, 50.80 and 48.72) were recorded in T6 - CIM- Ayu and Seaweed extract @ 10% (V1B6). Whereas the maximum content of Limonene (1.77, 1.82 and 1.79), Linalool (1.49, 1.54 and 1.51), Methyl chavicol (1.40, 1.45 and 1.42) and Beta elemene (14.19, 14.65 and 14.42) were recorded in T13 - CIM- Angana and Seaweed extract @ 10% (V2B6) during the years 2021, 2022 and pooled respectively

Keywords

Biostimulants, eugenol, seaweed extract, caryophyllene

Conclusion

The studies on different biostimulants and varieties revealed that the oil yield and composition of sacred basil were influenced by biostimulants. The present study indicated that crop grown with T6 - CIM- Ayu and Seaweed extract @ 10% (V1B6) recorded significantly highest yield parameters like Oil yield per plant (g/plant), Oil yield per plot (g/plot) and Oil yield per hectare (Kg/ha), Quality parameters viz., maximum content of Eugenol, Methyl eugenol, Caryophyllene and Chlorophyll content (SPAD meter reading) during the years 2021, 2022 and pooled respectively. Whereas the maximum content of Limonene, Linalool, Methyl chavicol and β – elemene were recorded in T13 - CIM- Angana and Seaweed extract @ 10% (V2B6) during the years 2021, 2022 and pooled respectively
