Response of sprouting broccoli to foliar application of boron and molybdenum under terai region of West Bengal

The present experiment was conducted to standardize the foliar application of boron (0, 0.3% at 45 days after transplanting (DAT) and 0.3% at 30+45 DAT as borax) and molybdenum (0, 0.05% at 45 DAT and 0.05% at 30+45 DAT as ammonium molybdate) for expecting high yield with better quality of sprouting broccoli. Plant height, number of leaves per plant, different yield contributing characters, total yield per plant and quality increased with the increase in boron levels. Single application of ammonium molybdate @ 0.05% at 45 DAT gave maximum total yield per plant, ascorbic acid and chlorophyll content of head. Combined application of borax @ 0.3% at 30+45 DAT and ammonium molybdate @ 0.05% at 45 DAT (B₂M₁) were found better in terms of total yield per plant along with ascorbic acid and chlorophyll content of head than their individual application over the control.
