Abstract: An experiment was conducted in Randomized Block Design at Horticulture farm, S.K.N. College of Agriculture, Jobner during rabi season of 2009-10 to study the effect of biofertilizers Azospirillum, Azotobacter and PSB and different fertility levels of NPK on growth, yield and quality of Knol-khol (Brassica caulorapa L.). The experiment consist of 16 treatment combinations viz., four levels of fertility (control, 50%, 75% and 100% recommended dose of NPK) and four different biofertilizer inoculations (control, Azotobactor, Azospirillum and PSB). Among different bio-fertilizers the inoculation of PSB leads to maximum plant height, number of leaves per plant, knob diameter, biological yield per plant, average weight of knob, volume of knob, yield of knob per hectare, NPK content in Knob, protein content, ascorbic acid and chlorophyll content over rest of Biofertilizers but at par with Azospirillum. The inoculation of Azotobacter also recorded better performance. These bacterial inoculants responded to with an increase in growth, yield and quality parameters as compared to control. So, better results were obtained by the application biofertilizer inoculants.
