Abstract: The results of the experiment was revealed that the ridge method of planting resulted in significantly highest protein content (6.34%) over furrow and flat method of planting and maximum TSS (12.52%) was also recorded with ridge method which was at par with rest of both sowing methods. Significantly more bolting percentage was recorded with flat method while minimum with ridge method. The alowest bolting percentage (4.71%) over those inoculated with Azospirillum. Application of poultry manure @ 4.2 t/ha resulted in significantly highest bulb yield (142.26 q/ha) and lowest bolting (4.51%) as compared to rest of the treatments of organics. The bulb yield per hectare of kharif onion differed significantly among both bio-fertilizer treatments. The maximum bulb yield of 136.36 q/ha was recorded with PSB inoculated seedlings while seedlings inoculated with Azospirillum gave minimum bulb yield (133.33 q/ha). Interaction of planting methods and organics exerted significant effect on bulb yield. The bulb yield (160.55 q/ha) was obtained from the treatment combination P3S6 (seedlings transplanted on ridges with 4.2 t PM/ha) followed P3S4 and P3S2. The interactions were found not significant response with these parameters. Seedlings inoculated with PSB transplanted on ridges with 25.0 t FYM/ha and PSB 5 kg/ha (P₃S₂B₁) accrued the highest net monetary return amounting Rs. 97060/ha followed by P₃S₂B₂ (Rs. 93790/ha) and P₃S₁B₁ (Rs. 91260/ha) while the highest B: C ratio of 2.65 was obtained with the treatment combination ridge planting with 12.5 t FYM/ha and PSB 5 kg/ha closely followed by P₃S₁B₂ (2.58), P₃S₂B₁ (2.57) and P₃S₂B₂ (2.52).
