The field experiments were carried out during 2016-17 at Department of Seed Science and Technology, UAS Dharwad. There are 18 treatment combinations involving two seasons viz., kharif season 2016 and rabi season 2016-17 and plant growth regulators as other factor viz., G1: Control, G2 : GA3 @ 50 ppm, G3 : NAA @ 40 ppm, G4 : Cycocel @ 100 ppm, G5 : Mepiquat chloride @ 50 ppm, G6 : Nitrobenzene @ 200 ppm, G7: TIBA @ 50 ppm, G8 : Brassinosteroids @ 200 ppm, G9 : GA3 @ 5 ppm + IAA @ 5 ppm. The results shows that more number of branches (9.83) per plant at harvest , higher relative chlorophyll content (SPAD value) (49.76), days to flower initiation (41.59) and also for less days to 50 % flowering (45.97) days and early (51.91) days to pod initiation and (90.50) days to pod maturity compared to kharif season (S1) except plant height. Among the plant growth regulator foliar spray, higher plant height and number of branches (114.80 cm and 10.87, respectively) at harvest, higher relative chlorophyll content (SPAD value) (51.08) ,early flower initiation , pod maturity was recorded in NAA @ 40 ppm and least was seen in control plots (G1) followed by in nitrobenzene @ 200 ppm. The interaction effect was found to be non significant However, foliar spraying of NAA @ 40 ppm recorded higher growth and yield attributing parameters as compared to control.
Key words: Dolichos bean, Rabi season, NAA, nitrobenzene, SPAD value and Seed yield.
