EFFECT OF PLANT SPACING AND MICRONUTRIENTS ON GROWTH AND YIELD OF CAULIFLOWER

Abstract

The experiment was conducted in the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka from November 2015 to February 2016. The experiment consisted of two factors, such as Factor A: Plant spacing (3 levels) as- S 1 : 50 cm × 50 cm, S 2 : 50 cm × 40 cm, S 3 : 50 cm × 30 cm and Factor B: Levels of micronutrients (4 levels) as- T 0 ii : B 0 Mo 0 (control), T 1 : B 1.0 kg/ha, T 2 : B 2.0 Mo 1.0 kg/ha, T 3 : B 3.0 Mo 1.5 kg/ha. The two factorial experiment was laid out in Randomized Complete Block Design with three replications. Plant spacing and micronutrients influenced significantly at all the studied parameters. In case of plant spacing, the highest curd yield (39.89 t/ha) was found from S 2 and the lowest curd yield (35.00 t/ha) was found from S 1 Mo 0.5 . For micronutrients, T 2 treatment produced the highest curd yield (46.85 t/ha) and the lowest (24.41 t/ha) was from control. For combined effect, the highest curd yield (51.56 t/ha) was obtained from S 2 T 2 and the lowest curd yield (20.33 t/ha) from S 1 The highest benefit cost ratio (2.59) was noted from S 2 T 2 treatment and the lowest 1.02 from S 1 T 0 . So 50 cm × 40 cm spacing and B 2.0 Mo 1.0 kg/ha was best for growth and yield of cauliflower.
