Abstract: An experiment entitled “Effect of priming on seed characters, disease incidence & yield in French bean (Phaseolus vulgaris L.)” was conducted during Rabi 2018-19 in the Vegetable Research field, Department of Vegetable Science, College of Agriculture, Odisha University of Agriculture and Technology, 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 (Pseudomonas fluorescens 10%), T₇ (Trichoderma viride 10%), T₈ (GA₃ 50 ppm+ T. viride 10%), T₉ (Sodium Molybdate 500 ppm +Pseudomonas fluorescens 10%), T₁₀ (Control). The seeds of French bean variety Harsha were taken and different priming treatments were done in the laboratory followed by growing the crop in the field as per recommended package of practices. Priming with (GA₃ 50 ppm + T. viride10%) was found the best in reducing leaf anthracnose and root rot by 62.9% and 75.9% respectively. The vitavax 2g/kg was the next best priming treatment which reduces anthracnose and root rot by 53.2% and 63.8% respectively. The seed quality parameters as studied in laboratory revealed the highest germination of 84.2%, seedling length of 43.00 cm, vigour Index –Ι of 3620.6 and vigour Index –ΙΙ of 72.41 in KCl @ 2%. From the present experiment it can be concluded that if KCl @ 2% is used for priming of French bean seeds it produces better yield attributing character & also recorded the better yield of 13.28 t/ha followed by 12.19t/ha with (GA₃ 50 ppm+ T. viride 10%) and the lowest pod yield of 8.10 t/ha was obtained in unprimed control.
