The study was conducted in the horticulture of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from March to June 20013 to find out the effect of sowing time on the growth and yield of Gimakalmi. The experiment consisted of three levels of sowing time, such as S1: Sowing on 16 March, S2¬: Sowing on 30 March and S3: Sowing on 15 April. The longest (24.67 cm) plant was recorded from S2, while S1 gave the shortest (18.57 cm) plant at 75 DAS during 4th harvest. The maximum (51.46) number of leaves per plant was recorded from S2, while S1 gave the minimum (49.35) number of leaves per plant at 75 DAS during 4th harvest. The highest (76.00 g) fresh weight of leaves per plant was recorded from S3, while S1 gave the lowest (71.86 g) fresh weight of leaves per plant at 75 DAS during 4th harvest. The highest (10.13%) dry matter content of leaves was recorded from S3, while S1 gave the lowest (9.36%) dry matter content of leaves at 75 DAS at 4th harvest. The highest (16.45 t/ha) yield was recorded from S3, while S1 gave the lowest (13.53 t/ha) yield at 75 DAS during 4th harvest.
