Abstract: A field experiment was conducted at Horticulture farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during kharif, 2013 with sixteen treatment combinations including four levels of organic manures (Control; FYM @ 10 t ha-1; FYM @ 5 t ha-1 + vermicompost @ 2.5 t ha-1; FYM @ 5 t ha-1 + vermicompost @ 2.5 t ha-1+ bio-fertilizers) and four levels of inorganic fertilizers (Control, 100% R D of NPK, NPK + S, NPK + S + Zn) in Randomized Block Design with three replications. The results indicated that combined application of FYM @ 5 t ha-1 + vermicompost @ 2.5 t ha-1 + Bio-fertilizers, among the different treatments of organic manures proved significantly superior over rest of the treatments in respect to yield attributes viz., neck thickness(1.069cm), diameter of bulb (4.22cm), average weight (98.80g), bulb yield(15.81kg plot-1), total bulb yield (219.56 q ha-1) ; net return (Rs. 2,01,705/- ha-1) and B:C ratio (3.26:1). Similarly yield attributes viz., neck thickness(1.056cm), diameter of bulb(4.29cm), average weight(96.14g), bulb yield (15.38 kg plot-1), total bulb yield (213.64 q ha-1); net return (Rs 195489 ha-1), B: C ratio (3.21: 1) in onion bulb were significantly high in treatment of NPK,S & Zn @ 100:50:100:20 & 10 kg ha-1.
