The present study was documented to determine about growth regulators and nutrient response on the black gram growth and yield parameters. The treatments include Gibberellic acid, salicylic acid, manganese sulphate, zinc sulphate, magnesium sulphate and Calcium chloride. The results revealed that the seeds fortified with gibberellic acid recorded higher growth & quality parameters like germination percentage (96), speed of germination (29.65), seedling length (39.41), dry matter production (g) (0.48), vigour index I (3783.36), vigour index II (46.08), field emergence (94.00), days to 50% flowering (30.59) and yield parameters viz., no. of plants/plant (6.06), no. of nodules/plant (11.84), pod length (8.84), number of pods per plant (35.28), number of seeds per pod (7.28), Seed yield/pt (6.22), 100 seed weight (6.83) significantly higher when compared to control.
