Abstract: The present experiment was laid out in randomized complete block design with four replications with aims to determine Effect of organic farming on yield, yield parameters and storage quality of onion (Allium cepa L.) in Rabi season during 2016-17 at experimental farm of TCA; Dholi with five treatments (var. Agrifound Light Red) planted in December. Observations were recorded on all the five plants maintained carefully in each plot for six quantitative characters viz., TBY=Total bulb yield (q/ha), DB=Double bulbs (%), BB=Bolter bulbs (%), MBY=Marketable bulb yield (q/ha), cost benefit ratio (B:C ratio), total storage losses % (TSL) and dry matter yield (kg/ha) were recorded. Among the treatments, maximum total bulb yield (258.38 q/ha) by T₅-INM (recommended package of practices-Inorganic + organic source) followed by T₁-Vermicompost @ 15 t/ha and T₃-Farm Yard Manure @ 30 t/ha with (237.38 q/ha) and (222.65 q/ha) respectively, were recorded. In case of marketable bulb yield, T₅-INM (recommended package of practices-Inorganic + organic source) followed by T₁-Vermicompost @ 15 t/ha given maximum marketable bulb yield (250.02 q/ha) and (230.01 q/ha) respectively. Maximum cost benefit ratio was found by T₅-INM (recommended package of practices-Inorganic + organic source) followed by T₁-Vermicompost @ 15 t/ha with (2.61: 1) and (2.34: 1) respectively. Minimum total storage losses was recorded by T₁-Vermicompost @ 15 t/ha with (71.25 %) which was best from rest treatments during investigation. Maximum dry matter yield by T_2-Poultry manure @ 15 t/ha was significantly superior one.
