The field trail was undertaken on the crop broccoli in the Rabi season of 2022-23 at Agriculture Research Farm, School of Agricultural Sciences and Technology RIMT University, Mandi Gobindgarh, Punjab to find out the “Effect of different transplanting dates on performance of different varieties on growth of broccoli”. The soil of the experimental plot had a slightly alkaline texture, a naturally occurring pH of 7.5, level of organic carbon (0.62%) and available amounts of N (430.32 kg/ha), P (17.54 kg/ha) and K (251.65 kg/ha). The experiment was designed in Factorial randomized block design (FRBD), replicated with three times and included nine treatments i.e. D1V1 (5th November + Rani Hybrid), D2V1 (15th November + Rani Hybrid), D3V1 (25th November + Rani Hybrid), D1V2 (5th November + Palam Samridhi), D2V2 (15th November + Palam Samridhi), D3V2 (25th November + Palam Samridhi), D1V3 (5th November + Bobby Hybrid), D2V3 (15th November + Bobby Hybrid) and D3V3 (25th November + Bobby Hybrid). The results indicated that significantly higher growth parameters viz., number of leaves per plant, plant height, leaf length, width and plant spread was observed  on the 15th November transplanting as compared to 5th November  and 25th November transplanting dates. In conclusion establishment of variety Palam Samridhi showed an excellent result on the 15th November transplanting date as compared to other transplanting dates.
