A green house experiment was carried out at Department of Agricultural Microbiology, GKVK, Bengaluru by use of IAA (MZL -8 and TCL -1) and GA3 (CAL – 1 and ACL- 3) producing yeast isolates on growth of tomato crop by spraying method with 8 treatments and 3 replication. The highest plant height, number of leaves per plant, number of branches per plant, root length, fresh shoot biomass, dry shoot biomass, fresh root biomass, dry root biomass, IAA and GA3 content, 44.73 cm, 80, 11.40, 14.70 cm, 24.00 g/plant, 11.75 g/plant, 7.98 g/plant, 3.91 g/plant, 1.205 μg/g of leaf and 0.550 μg/g of leaf, respectively by the yeast isolate TCL -1.The least plant height, number of leaves per plant, number of branches per plant, root length, fresh shoot biomass, dry shoot biomass, fresh root biomass, dry root biomass, IAA and GA3 content, 22.20 cm, 55.70, 8.00,9.00 cm, 11.00 g/plant, 6.23 g/plant, 3.67 g/plant, 2.07 g/plant, 0.384 μg/g of leaf and 0.200 μg/g of leaf, respectively was recorded by control (T1) treatment at 50 DAT.
