Key words: Multiplier onion, Zinc and boron application, Growth.


The experiment was carried out in order to study the effect of zinc and boron application on seeding transplanting multiplier onion CO(On)5 at different levels of both foliar and basal application. The treatment consist of soil application of zinc sulphate (5 kg ha-1 and 10 kg ha-1), Borax (5 kg ha-1 and 10 kg ha-1), foliar application of zinc sulphate (0.5% foliar) and Borax (0.25% foliar), zinc sulphate (5 kg soil + 0.5% foliar), zinc sulphate (10 kg ha-1 soil + 0.5% foliar), borax (5 kg ha-1 soil + 0.25% foliar), borax (10 ha-1 kg soil + 0.25% foliar) and control without micronutrient, replicated thrice in a randomized block design. OLYMPUS DIGITAL CAMERAResults were found to be significant in most of the yield contributing parameters of multiplier onion. The plant height (50.30 cm), number of leaves per plant (51.3), leaf girth (8.1 mm), fresh leaf weight (22.7 g), fresh bulb weight (85.4 g), total dry matter production (5.31 t ha-1), bulb yield per plot (10.1 kg) and bulb yield per hectare (16.9 t ha-1), Ascorbic Acid (16.70 mg 100g-1) were highest in zinc sulphate 0.5% foliar spray; while 10 kg ha-1 borax soil application showed highest polar (26.0 mm) and equatorial diameter (27.2 mm) and borax (5 kg ha-1 soil + 0.25% foliar), highest number of bulblets per clump (8.8) in borax (10 kg ha-1 soil). The highest TSS content (21.30 °Brix) was observed in soil application of zinc sulphate (10 kg ha-1) application.
