Abstract

An experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2013 to March 2014 to study the effect of potassium and GA3 on the growth and yield of tomato. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and consisted of two factors. Factor A is consisting K0 = Control (No fertilizer), K1 = 120 kg, K2 = 150 kg and K3 = 180 kg K2O/ha respectively and Factor B is consisting G0 = Control (No GA3), G1 = 40 ppm and G2 = 60 ppm GA3 respectively. In case of potassium, K1 produced the highest yield (59.45t/ha) and K0 produced the lowest yield (51.33 t/ha). In case of GA3, G1 produced the highest yield (58.66 t/ha) and G0 produced the lowest yield (46.55 t/ha). Combined effect of K1G1 produced the highest yield (70.77 t/ha) and K0G0 produced the lowest yield (43.89 t/ha). The highest (4.75) benefit cost ratio was recorded from the combination of K1G1. Therefore, 120 kg K20/ha with 40 ppm GA3 was found suitable for growth and yield of tomato.
