The experiment was carried out in shade house (G1) and open field condition (G2) with 45x15 cm (S1) and 60x15 cm (S2) spacings and five foliar sprays consists NAA @ 25 ppm, 50ppm and IAA @ 25ppm, 50ppm with control in both season of 2015-16. In shade house, plant height was significantly higher in kharif (40.19 cm) and rabi (38.05 cm) at harvesting. Similarly, more number of days to pod maturity (92.39 and 92.83 days), number of pods per plant (17.07 and 18.09), pod yield per hectare (28.61 and 28.02 q), seed yield per hectare (22.72 and 23.16 q), hundred seed weight (37.79 and 38.06 g), seed germination (92.22 and 94.33 %), seedling vigour index (3137 and 3218) in kharif and rabi season respectively. The spacing 60x 15 cm recorded significantly higher number of pods per plant (16.80 and 18.54), seed weight per pod (16.80), pod yield per plant (45.47 and 48.74 g), hundred seed weight (36.17 and 36.52 g), seed germination (90.07 and 91.40 %) and seedling vigour index (2972 and 3128) and spacing 45 x 15 cm recorded significantly higher pod yield per hectare (24.64 and 24.56 q ) and seed yield per hectare (19.19 and 20.27 q) in kharif and rabi season respectively. Among the growth regulators spray, NAA at 50ppm recorded significantly higher number of pods per plant (17.77 and 18.91), pod yield per hectare (24.81 and 25.63 q), seed weight per pod (1.84 and 1.85 g), seed yield per hectare (19.52 and 21.11 q) and hundred seed weight (36.72 and 37.33 g) in kharif and rabi season respectively.EnglishThesis
