Seeds of JS 335 variety were primed with different fungicides and bio-agents and were subjected for seed germination and field performance in order to know the influence of fungicides and biocontrol agents on germination, seedling growth, disease incidence and yield parameters. Under laboratory condition, combi-fungicides carboxin 37.5 + thiram 37.5 WS @ 0.2% recorded significantly higher seed germination and root length. Whereas, Trichoderma harzianum @ 0.6% recorded maximum shoot length and significantly higher seedling length. Seed priming with tebuconazole 5 EC @ 0.2%, captan 70 + hexaconazole 5 WP @ 0.2%, and carbendazim 25 + mancozeb 50 WS @ 0.2% recorded significantly higher seedling dry weight as compared to control. The field experiment indicated that the Bacillus subtilis @ 0.6% recorded significantly higher seed yield followed captan 70 + hexaconazole 5 WP @ 0.2% and carbendazim 25 + mancozeb 50 WS @ 0.2%. The increase in seed yield was attributed to increased number of pods per plant, pod weight, seed weight in primed treatments as compared to control. The incidence of purple seed stain (PSS) disease was less in these treatments as compared to control.
