Abstract:

An experiment was conducted to evaluate the efficacy of micronutrients on performance of Onion cv. Sukhsagar at Nadia, West Bengal during 2017-2018.The experiment was laid out in RBD having four replication with six treatments each having FYM @ 20 t ha-1, viz. T1 (RDF + soil application of Zinc Sulphate @ 10.0 kg ha-1), T2 (RDF+ foliar application of Zinc Sulphate @ 0.5% at 30 & 45 days after planting (DAP), T3 (RDF+ soil application of Borax @ 10.0 kg ha-1), T4 (RDF+ foliar application of Borax @ 0.25% at 30 & 45 DAP), T5 (RDF+ Foliar application of Micronutrient Mixture i.e. iron-2.5%, boron-0.5%,zinc -3%, copper -1%and manganese-1% @ 0.5% at 30 & 45 DAP) and T6 (control). Highest plant height (63.72 cm), number of leaves/plant (12.71), polar diameter (58.62 mm), equatorial diameter (46.88 mm), average weight (61.72 g) of bulb, yield ha-1 (266.80 q) and highest % (29.82) of A grade bulbs, were recorded with Tâ‚… followed by T4.Hence, it is concluded foliar application of micronutrient mixture @ 0.25% followed by borax @ 0.5% at 30 and 45 DAP is better in respect of bulb growth and yield.
