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.
