One of the most important pre sowing seed improvement techniques for managing biotic and abiotic challenges is seed bio-priming, which ensures uniform stand establishment under adverse conditions. "Bio-priming" seed treatment combines biological (inoculating seeds with protective organisms) and physiological (hydrating seeds) components of disease management. Recently, it has been employed as an alternate technique for eradicating numerous soil- and seed-borne diseases. In the current study, an On-Farm Trial with three biopriming treatments viz,.(i) 10% Tirchoderma viridae, (ii) 10% Pseudomonas flurescence, and (iii) in combination of 5% Tirchoderma viridae and 5% Pseudomonas flurescence for 6 hours was conducted in farmers' fields during Rabi, 2020. Untreated seeds served as the control. The findings showed that 10% Tirchoderma viridae outperformed other biopriming seed treatment in terms of yield (165.1 q/ha), net return (Rs. 93, 340/ha), and benefit-cost ratio (2.36), than the untreated control. The 10% Pseudomonas flurescence primed seeds, which was the next-best treatment, had high yields, net returns, and BCR values of 162.3 q/ha, Rs. 90,340/ha, and 2.28 respectively. So, it was concluded that biopriming of seeds with 10% Tirchoderma viridae for six hours increased the production of bhendi. Hence, through dissemination of extension activities like training and method demonstration revealed that the understanding of farmers about bioprming rose from 12.5 to 87.5 percent
