An experiment entitled "Effect of seed priming on growth behaviour of French bean Phaseolus vulgaris L." was conducted during Rabi 2018-19 in the Vegetable Research field of Department of Vegetable Science, College of Agriculture, OUAT, Bhubaneswar. The trial was conducted in Randomized Block Design with three replications and ten treatments. The treatments were T1 (Hydro priming), T2 (GA3 50 ppm),T3 (KCl 2%),T4 (Sodium Molybdate 500 ppm),T5 (Vitavax 2g/kg), T6 (Pseudomona fluorescens 10%), T7 (Trichoderma viride 10%), T8 (GA3 50 ppm+ T .viride 10%), T9 (Sodium Molybdate 500 ppm +Pseudomonas fluorescens 10%), T10 (Control) Good quality seeds of French bean variety Harsha was taken and different priming treatments were done in the laboratory followed by growing the crop in the field as per recommended package of practices. However days to 1 st flowering & 50% flowering were found non-significant. Days to 50% flowering varied from 45.5 in T6 to 48.7 in T4. The average leaf area of the trifoliate compound leaves were taken which was highest in T3 (148.30) followed by T8 (140.40 cm 2 ) and was lowest (105.8 cm 2 ) in control. The highest stem girth (2.8 cm) was recorded in KCl (2%) primed seeds closely followed by GA3 (50PPM) + T. viride (10%) (2.7cm) and vitavax treatment @ 2g/kg (2.6 cm). The number of primary branches per plant was maximum in T3 (4.52) and minimum in T10 (2.87) and this character differed significantly among the treatments. The treatments T3 (4.52), T8 (4.32), T6 (4.14), T5 (4.01) produced more branches and they are at par.
