Radish, beet root and carrot three tuber vegetables and lettuce green leafy vegetable was grown in seedling trays under greenhouse condition to evaluate the effect of different bio fertilizers on germination percentage and seedling growth parameters. All the crops were grown in seedling trays containing coco pith and vermicompost at 2:1 ratio. Biofertilizers applied were broth cultures of phosphorus solubilizing bacteria (PSB), potassium mobilizing bacteria (KMB) and potassium solubilizing bacterial isolates (KSB), isolated from different potassium containing minerals. Among the three biofertilizers, T9 and T3 recorded significant results and the other treatments are on par with each other. Highest germination percentage and seedling vigour was recorded in T9 and T3 respectively in radish. In case of carrot, maximum fresh weight and seedling vigour was observed in T9 and number of leaves observed highest in T3 and T6. Germination percentage was also recorded highest in T6. Beet root growth was also highly influenced by the application of biofertilizers and (KMB) T9 recorded significantly highest growth. Root length, shoot length, number of leaves and seedling vigour was recorded highest in T9, whereas, fresh weight and dry weight was observed highest in T7. In lettuce all the treatments showed different results. T3 recorded maximum seedling vigour highest shoot length and fresh weight was observed in T6 and maximum number of leaves was recorded in T8. In all the crops, control showed least growth and germination percentage.
