ABSTRACT
Phenological responses were studied on five mango cultivers viz. BARI Mango-1, BARI Mango-3, BARI Mango-4, Langra and Fazli mango variety at Fruit Research Farm of Horticulture Research Center (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur, Bangladesh during August 2013 to July 2015. The result revealed that plants of BARI Mango-4 were prompt in primary vegetative flushing while BARI Mango-3 was found late. Number of new buds per shoot was varied significant and it was the height in BARI Mango-3 (2.00) followed by BARI Mango-1 (1.50) and Langra (1.15), while the BARI Mango-4 produced the lowest buds/shoot (0.95). The Langra required maximum days for the completion of primary vegetative flushing (120 days) and BARI Mango-3 required minimum (59 days). Number of new leaves per shoot was also varied significantly and among the varieties it ranged from 10.75 to 7.6. Among the mango varieties BARI Mango-1 took the shortage period (223 days) from vegetative flushing to inflorescence opening, while Langra required longer period (253 days). Days to fruit set to inflorescence opening was found wider in BARI Mango-4 (27 days)and that of shorter in Langra (16 days). Maximum days to harvest from fruit set were observed in BARI Mango-4 (150 days).
