A study was conducted at the Bangladesh Agricultural Research Institute, Joydebpur during September, 1986 to October, 1988 to investigate into the effect of time of planting on growth and yield of Amritsagar and Sabri varieties of banana. There were three dates of planting viz. 18 September, 1986 and 18th of February and May, 1987. Sabri plants were taller (251.3 cm) than Amritsagar (202.0). May planting had the tallest plants (252.4 cm) followed by September (232.5) and February (196.4) plantings. September planting produced more number of suckers (18.2) compared to February and May plantings (11.5). Number of green leaves were more at bunch shooting (12.4) but lesser at harvest (3.7) in case of May planting. Sabri had longer petiole (54.6 cm) than Amritsagar (34.0). Longest petiole (46.7 cm) was obtained in May planting which was followed by September (46.0) and February (40.2) plantings. Sabri had larger lamina (187.5 cm) than Amritsagar (169.8). May planting had larger lamina (193.3 cm) followed by September (186.0) and February (156.7) plantings. Interaction effect was also found significant in respect of plant height, top girth, number of suckers, number of green leaves both at bunch shooting and harvest and leaf size. September (360.5 days) and May (358.1) plantings took longer duration for bunch shooting than February planting (263.1). However, Sabri took longer duration (119.9 days) from bunch shooting to maturity than Amritsagar (90.9). February planting took longest duration(120.3 days) from bunch shooting to maturity followed by September (104.8) and May (91.1) plantings. Sabri took longer duration (453.8 days) to harvest than Amritsagar (411.4). September (465.2 days) and May (449.2) plantings had similar crop duration while February planting took least crop duration (383.4)

Both Amritsagar (7.72 kg plant-1) and Sabri (8.37) produced similar yield. However, May planting had maximum yield (11.10 kg plant-1) followed by September (7.73) and February (5.32) plantings. Number of hands and fingers produced by Amritsagar and Sabri were 5.2 and 6.7 and 82.9 respectively. On the other hand, May plantings produced largest number of hands (7.1) and fingers (92.9) followed by September (6.0 and 74.2) and February (4.8 and 50.5) plantings.

May plantings was found best for both the varieties while February planting took least crop duration.
