The experiment was conducted in the Central Farm, Sher-e-Bangla Agricultural University, Dhaka from November 2015 to February 2016 with the aim of investigating the growth and yield attributes of cauliflower as influenced by different micronutrients and plant spacing. The experiment consisted of two factors, such as Factor A: Plant spacing (3 levels) as- S1: 50 cm × 50 cm, S2: 50 cm × 40 cm, S3: 50 cm × 30 cm and Factor B: Levels of micronutrients (4 levels) as- T0: B0Mo0 (control), T1: B1.0Mo0.5 kg/ha, T2: B2.0Mo1.0kg/ha, T3: B3.0Mo1.5 kg/ha. The experiment was laid out in Randomized Complete Block Design with three replications. All the studied parameters were significantly influenced by micronutrients and plant spacing. In case of plant spacing, the highest curd yield (39.89 t/ha) was found from S2 and the lowest curd yield (35.00 t/ha) was found from S1. For micronutrients, T2 treatment produced the highest curd yield (46.85 t/ha) and the lowest (24.41 t/ha) was from control. In case of combined effect, the highest curd yield (51.56 t/ha) was obtained from S2T2 and the lowest curd yield (20.33 t/ha) from S1T0. Therefore, it can be suggested that the highest curd yield and good shape cauliflower curd can be obtained in plant spacing 50 cm × 40 cm with the combined application of B 2.0 kg/ha and Mo 1.0 kg/ha.
