Abstract: A field experiment entitled Effect of different levels of nutrients on vegetative growth of pineapple cv. Kew was conducted at College of Horticulture, Sirsi, UHS, Bagalkot, Karnataka during 2017-2019. The experiment was carried out in split plot design with three replications. The main treatments comprising T1: Control, T2: Azotobacter, T3: PSB, T4: VAM and Sub treatments - S1: 80% RDN + 20% RDN through Vermicompost, S2:80% RDN + 20% RDN through FYM, S3:100% RDN + ZnSO4 (10 kg/ha) + Boron (5 kg/ha), S4: RDN (350:130:440 NPK kg/ha) control, S5: S1 + ZnSO4 (10kg/ha) + Boron (5 kg/ha), S6: S2 + ZnSO4 (10kg/ha) + Boron (5 kg/ha). The result revealed that all the growth parameters are significantly affected by different levels of organic, inorganic nutrients and biofertilizer treatment combination. With respect to different plant growth parameters like number of leaves (41.40), D leaf length (64.00 cm), D leaf breadth (3.64 cm), leaf length (64.00 cm), leaf breadth (3.67 cm) and leaf area (8853.11 cm2) were found effective with treatment combination T2S5 [Azotobacter (5 kg/ha) + 80% RDN+20% RDN through vermicompost +ZnSO4 (10 kg/ha) + Boron (5 kg/ha)]. Whereas, T3S5 [PSB (5 kg/ha) + 80% RDN + 20% RDN through vermicompost + ZnSO4 (10 kg/ha) + boron (5 kg/ha)] recorded higher plant height (80.53 cm).
