An experiment was conducted in the Horticultural Farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from October 2010 to March 2011 to find out the effect of GA3 and seedling age on the growth and yield of tomato. The experiment was laid out in randomized complete block design (RCBD) with three replications. The experiment consisted of four concentration of GA3 such as control G0 = no GA3, G1= 75 ppm GA3, G2 = 100 ppm GA3 and G3 =125 ppm GA3; three different seedling ages such as S1= 20 days, S2 = 25 days and S3 = 30 days old seedling. All parameter varied significantly at different concentration of GA3 in different DAT. The combined effect of G3S3 (125 ppm GA3 with 30 days old seedling) gave the maximum yield (90.28 t ha-1), on the other hand combined effect of G0S1 (no GA3 with 20 days old seedling) gave the minimum yield (59.83 t ha-1). The maximum yield (2.79 kg) plant-1 was recorded from treatment combination of G3S3 and the minimum yield (1.20 kg) was recorded from treatment combination G0S1. The maximum yield (32.47 kg) plot-1 was recorded from treatment combination G3S3 and the minimum yield (21.52 kg) plot-1 was recorded from treatment combination G0S1. The maximum yield (90.28 t ha-1) was recorded from treatment combination of G3S3 and the minimum yield (59.83 t ha-1) was recorded from treatment combination of G0S1. Therefore, 125 ppm GA3 with 30 days old seedling was found suitable combination for tomato production.
