A field experiment was conducted to study the effect of soil drenching and foliar application of different biostimulants on physiological and quality parameters of curry leaf (Murraya Koenigii Spreng.) at Karamadai, Coimbatore during 2019 to 2021. This study was laid out in factorial randomized block design with control, factor 1 as soil drenching (D1- humic acid @ 5 ml/plant and D2- jeevamrutham @ 50 ml/plant), factor 2 as foliar spray of different biostimulants (S1- Effective microorganism culture @ 2 %, S2- Egg amino acid @ 1%, S3-Panchagavya @ 3%, S4- Sea weed extract @ 2% and S5- Pink Pigmented Facultative Methylotrops (PPFM) @ 1 % and control as farmer practices. The experimental results revealed that significantly higher leaf area (9.88 cm2), leaf area index (15.36), chlorophyll a (0.89 mg/g), chlorophyll b (0.66 mg/) and total chlorophyll (1.80 mg/g), relative water content (74.41%) and fresh herbage yield (840.18g) in the treatment D1S3 (Humic acid + Panchagavya @3 %). Quality parameters like essential oil (0.19%) and oleoresin (2.86%) were significantly higher in the treatment D1S4 (Humic acid + sea weed extract).
