A field experiment was conducted during the Rabi season to find out the effect of organic manures, biofertilizers and micronutrients on growth, yield and quality of onion cv. NHRDF Red - 2. There were 13 treatments viz., T0 (Recommended dose of fertilizers), T1 Poultry manure, T2 vermicompost, T3 Azotobacter, T4 VAM, T5 Azotobacter+RDF (50%)+zinc, T6 Azotobacter+RDF(75%)+zinc, T7 VAM+RDF(50%)+boron, T8 VAM+RDF (75%)+boron, T9 RDF (25%)+VAM+poultry manure (50%)+Azotobacter+boron, T10 (RDF (25%)+VAM+vermicompost (50%)+Azotobacter+boron, T11 RDF (25%)+VAM+poultry manure (50%) Azotobacter+zinc, T12 RDF (25%)+VAM+vermicompost 50% Azotobacter+zinc and the experiment was laid out under RBD with three replications. The study clearly revealed that there were significant effects of various treatments on the growth, yield and quality attributes of onion. The number of leaves per plant (12.15), plant height (73.02cm), neck thickness (22.00mm), bulb length (6.46 cm), bulb diameter (7.20cm), yield (398.36 kg/ha-1) were recorded maximum in treatment T12 whereas T.S.S (14 °B), vitamin C (12.11mg/100g), total sugars (10.52%), reducing sugar (6.23%) and non-reducing sugar (4.28%) were found maximum in T10 treatment as compared to other treatment. However, T12 was good for higher yield improvement and T10 was the best for quality improvement among the all treatments under study, the application of T12 (RDF (25%)+VAM+Vermicompost 50% Azotobacter+Zinc) may be suggested for successful cultivation of onion in Lucknow.
