Abstract An experiment was carried out for three years to produce onion organically using farm yard manure, vermicompost, neem cake and sheep manure in comparison with chemical fertilizer at RDF. Plant height, bulb weight and yield per ha were significantly influenced by different treatments. RDF produced tallest plants, while neem cake produced shortest plants. Diameter of bulb was maximum with vermicompost, while it was least with sheep manure. Vermicompost application resulted in highest bulb weight and bulb yield. The yield was least with sheep manure. RDF was at third in position in yield. However, the cost: benefit ratio was highest with RDF and least with sheep manure indicating organic farming in onion was not cheaper than farming with RDF.
