A two factorial experiment was conducted at dragon fruit orchard of Agricultural Research Station, Pahartali, Khulshi, Chattogram to find out the best lighting duration and bulb for off-season dragon fruit production. Two factors were bulb and lighting duration for this experiment. The performance 6 hours lighting duration was significantly superior than other treatments in case of bud/pillar (43.80), fruit/pillar (43.80), fruit length (9.31 cm), fruit breadth (8.5 cm), individual fruit weight (344.62 g), yield (16.58 t/ha). 100 W IB having light intensity 225.96 lux showed superior performance over other treatments in case of bud/ pillar (49.44), fruit/pillar (34.56), fruit length (9.54), fruit weight (336.99 g), TSS (9.28%), yield (18.13 t/ha). The treatment combination (100 W IB for 6 hrs lighting) produced the highest number of fruit/ pillar (36.33), bud/pillar (54.00), fruit length (9.66 cm), fruit breadth (8.99 cm), yield/ pillar (12.41 kg) and yield (19.85 t/ha).In control dragon fruit was unable to produce flowering due to short day length. So artificial lighting of 6 hrs with 100 W IB from 18 pm to 24 am was superior method for off-season dragon fruit production.</p> A.S. M. Harunor Rashid Md. Golam Azam S. M.
