A field experiment was conducted during Rabi seasons of 2012 and 2013 at fixed organic experimental plot of ICAR-India Institute of Horticultural Research farm, Hesaraghatta, Bengaluru to study the effect of different levels of farm yard manure (FYM) in organic as compared to chemical and conventional practices on growth, yield and quality of onion. The trial included five levels of farm yard manure and two inorganic nutrient supply treatments consisting of only chemical treatment (NPK fertilizers + chemical plant protection) and conventional practice (Recommended dose of FYM + NPK fertilizers + chemical plant protection).Conventional treatment recorded highest plant height (50.1 cm) as well as bulb yield (34.8 t/ha),while onion crop which had received organic manure equivalent to 100 per cent recommended dose of nitrogen (RDN) recorded highest number of leaves (10.5) per plant. This bulb yield was on par with the yields obtained in organic treatments receiving FYM equivalent to 50 to 100 per cent RDN. The lower bulb yields were with organic treatment receiving manures equivalent to 25 per cent RDN and treatment receiving only NPK fertilizers. There were no marked differences among the treatments for the quality parameters such as bulb dry matter and shelf life.
