The experiment was carried in Polly house at Agriculture Farm, School of Agricultural Sciences & Technology, RIMT University, Mandi Gobindgarh, Punjab, India to study the influence of GA3 and NAA on flowering, fruiting and yield attributes of capsicum cv. Indra under protected structures during 2020-21. Three levels each of GA3 (25, 50 and 75 ppm) and NAA (50, 100 and 150 ppm) along with a control (distilled water) were applied as foliar application after transplanting. Experiment was laid out in a randomized block design with three replications and all the required parameters were recorded and analysed statistically. Results revealed that application of GA3 @ 75 ppm resulted with minimum days to flowering (34.33), fruiting (44.33) and longer duration of fruiting (48.27 days) whereas, more number of flowers/cluster (4.73), number of fruits/plant (15.23), fruit setting (65.60%), average fruit weight (45.60 g), fruit yield/plant (0.69 kg), fruit yield/plot (6.95 kg) and fruit yield/ha (43.42 t) while, less days to fruit maturity (60.00) was reported under the application of NAA @ 100 ppm.
