An experiment was accomplished at Sher-e-Bangla Agricultural University during the period of July 2018 to January 2019 to adopt flower forcing technology for off season mango production. The study comprised four treatments (i) Control: No chemical application, (ii) 1g PBZ L-1 (Paclobutrazol) water, (iii) 0.5g PBZ L-1 water and (iv) 0.25g PBZ L-1 water following completely randomized design with six replications. Data on flowering and fruit related parameter were taken and significant variation was observed with different treatments. Among them, maximum inflorescence number plant-1 (8.7), fruit number inflorescence-1 (4.5), fruit number plant-1 (30.8), harvested fruits plant-1 (8.3), fruit length (11.7cm), single fruit weight (273.8 g) and yield plant-1 (2.3 kg) was found in T2 treatment whereas, maximum days required to first flowering (100.0 days), minimum inflorescence number plant-1 (3.2), fruit number inflorescence-1 (3.0), fruit number plant-1 (12.3) recorded in T3 treatment and no flowering was observed in control. So, it could be concluded that, significant treatment effects were observed on different parameters where T2 treatment (0.5g PBZ L-1 water) gave best results. Therefore, it can also be articulated that a new flower forcing technology is developed which will be potential for off season mango production.
