Abstract: A study was conducted at Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal during rabi season (November- April) of 2010 and 2011. The main aim of the experiment was to enhance the production of onion through assessing the effect of different levels of boron and zinc. The experiment consisting of 4 levels of boron (0, 0.1, 0.2 and 0.5 %) and 4 levels of zinc (0, 0.1, 0.2 and 0.5 %) were applied as foliar spraying. Application of 0.5% boron significantly increased the growth (plant height, 63.93cm and number of leaf per plant, 7.25), yield (30.74 t ha-1) and quality (Total soluble solids, 13.45ºB and pyruvic acid 5.94 µmol.g-1) of onion. Among various levels of zinc 0.5% exhibited the best growth (plant height, 67.25 cm and number of leaf per plant, 7.75), yield (33.34 t ha-1) and quality (Total soluble solids, 14.57ºB and pyruvic acid, 5.86 µmolg-1) attributes of onion.
