An experimental was carried out at Regional Horticultural Research and Extension Centre (RHREC), University of Horticultural sciences campus, GKVK, post Bangaluru-560065, during the year 2019 – 20). The nursery was established in potting mixture; sand, soil and farm yard manure in the ratio of 2:1:1 (Sand: Soil: FYM;) taken in polythene bags of size 12 cm x 24 cm. Applied with bio-fertilizers such as Azospirillum spp., Phosphorus solubilizing bacteria (PSB), Pseudomonas flourescens and Vesicular Arbuscular Mycorrhiza (VAM)@ 6 g per plant soil based bio-fertilizers. Organic amendments such as Panchagavya, Jeevamrutha, Beejamrutha and bio-digested liquid were tested at 5 and 10 per cent (applied through foliar application at 30 days interval). A total of nine treatments were tested in four replications. The results at the end of 120 days showed that the combination of four bio-fertilizers; Azospirillum, Phosphorus solubilizing bacteria, Pseudomonas flourescensand VAM had highest Nitrogen per plant (0.636 g) (T5). However T3treatment had maximum Phosphorus (0.055 g/plant) and Potassium (0.150 g/plant) with inoculation of Azospirillum + PSB+VAM. The maximum bacterial population (4.40 CFU X 104g-1soil) was found in the treatment Azospirillum spp. + PSB +PF + VAM (T5), followed by T3 (3.75 CFU X 104g-1soil). The highest fungal population (2.60 CFU X 104g-1soil) was noticed in the treatment Azospirillum spp. + PSB) + VAM (T2), followed by T5 (2.55 CFU X 104g-1soil), the minimum NPK and microbial population was recorded in control treatment at the end of 120 days in nursery.
