An experiment was conducted at Vegetable Research farm, Bihar Agricultural University, Sabour, Bhagalpur, Bihar during2018 to explore the possibility of growing Kharif onion inBihar region for higher yield and economic return. A short day variety (Agrifound Dark Red) of Kharif onion was transplanted in three dates (21st July, 6th August and 22nd August) with seven PGRs concentrations (control (water spray), Ethephon 2000ppm,2500 and 3000ppm) and Cycocel (1500ppm2000and 2500ppm) in split- plot design with three replications. Observations were recorded on plant height and number of leaves per plant at 60 and 90 DAT, polar and equatorial diameter, average and marketable bulb yield. Economics of the various treatments was also calculated to study the most profitable treatment combinations. The experimental results revealed that the transplanting on22 August produced maximum plant height(63.01cm)and number of leaves (10.13) at 90 DAT, polar diameter(4.72cm), equatorial diameter(5.47cm), average bulb yield(86.49g) and marketable yield(321.63q/ha).Among PGRs, Cycocel 1500ppm resulted into higher equatorial diameter(5.37cm), average bulb weight (81.94g) and yield (281.34q/ha). So far as the economics is concerned the transplanting kharif onion on 22 August and spray of cycocel 1500ppm was found to be most economically viable as it produced the highest bulb yield and incurred maximum B: C ratio (2.69).
