The present study was undertaken to evaluate the efficacy of the bio-stimulant Phylgreen 200 (P-6084), developed by Tradecorp Rovensa India Pvt. Ltd., on the performance of summer greengram (Vigna radiata L.) under irrigated conditions. Conducted at the Agricultural Research Station, Amadalavalasa, during the summer of 2022, the experiment employed a randomized block design (RBD) with nine treatments and three replications. Treatments included different foliar doses (2.0, 2.5, 3.0, and 6.0 ml/l) of Phylgreen 200, applied at the first flowering and pod setting stages under both normal and drought-stressed conditions, with appropriate controls. The study recorded key biometric observations including plant height, number of flowers and pods per plant, 100-seed weight, and grain yield. Results revealed that all Phylgreen 200 treatments significantly outperformed controls with respect to growth and yield parameters. The application of Phylgreen 200 at 2.5 ml/l (T₂) and Drought Stress Phylgreen 200 at 2.5 ml/l (T₆) produced the highest grain yields (648.1 and 624.2 kg/ha, respectively) and return on investment (179.7% and 128.7%, respectively). Importantly, no phytotoxic symptoms were observed at any dosage, including the highest tested concentration of 6.0 ml/l. The results suggest that Phylgreen 200 enhances crop performance and economic returns in greengram cultivation, especially under drought stress. Further research is warranted to understand the physiological mechanisms underpinning the observed benefits.
