A field experiment was conducted to study the effect of plant growth regulators on growth, flowering, yield and quality of French bean cv. Arka Komal at student’s farm, College of Agriculture, Rajendranagar, Telangana. Different concentrations of the plant growth regulators viz., GA, NAA and CCC were sprayed at 20 and 40 days after sowing. The results showed that foliar spray of GA3 @ 250 ppm increased number of branches, number of leaves, intermodal length and leaf area index resulting in increased number of pods per plant, pod length, weight of 10 pods which significantly increased the yield/plant and yield/ha.
