The investigation was carried out at Regional Horticultural Research Station, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, Gujarat during rabi, 2015 in naturally ventilated polyhouse (NVPH). The whole experiment was arranged over ten treatments comprising of three levels each of three PGRs (NAA at 20, 40 and 60 ppm; GA3 at 25, 50 and 75 ppm and 2,4-D at 2.5, 5 and 7.5 ppm) and laid out in a Randomized Block Design with three replications. The results revealed that among different levels of treatment, 75 ppm GA3 exhibited maximum plant height of 85.00, 154.67, 214.67 and 239.53 cm at 60, 90, 120 days after planting and at final picking, respectively. Plants sprayed with 20 ppm NAA was found to be superior to all other treatments for majority of the reproductive parameters like fruit set (77.62 %), days to first picking (71.67), number of fruits per plant (26.00) and number of pickings (33.33). Nevertheless, duration of crop was enhanced to maximum number of days (206.67) in plants sprayed with 75 ppm GA3. The superiority of NAA at the rate of 20 ppm was also reflected by bell pepper plants in terms of maximum fruit breadth (7.95 cm), average fruit weight (185.00 g), fruit yield per plant (3.00 kg) and marketable yield per m2 (10.75 kg) except fruit length which was observed to be maximum in plants sprayed with 75 ppm GA3. Subsequently, economic analysis of investigation revealed T2 (20 ppm NAA) as highly remunerative treatment exhibiting BCR of 1.22 with net realization of ` 188849.00.
