A pot experiment was conducted in the polyhouse of forestry to show the effect of compost and Pseudomonas fluorescens alone and in combination on growth of Lycopersicon esculentum. The growth parameters selected for study were Plant height, Root length, Number of leaves per plant, Number of fruits per plant and Weight of fruit. The results obtained during the course of investigation were further analyzed statistically. Effect of different treatment of compost and PGPR on growth of Lycopersicon esculentum showed maximum growth in terms of plant height, root length, number of leaves and number of fruits on using T5 (combination of NPK, Compost and PGPR), as compared to other treatments .Finally it was revealed that dose of soil (1.5 kg) +NPK Recommended dose +Compost (1 kg) +PGPR treated soil was able to promote plant growth. Pseudomonas fluorescens (MCCB.0217) was shown to be a plant growth promoting agent for Lycopersicon esculentum. Hence, major research focus should be on the production of efficient and sustainable bio-fertilizers for crop plants, wherein inorganic fertilizer application can be reduced significantly to avoid further pollution problems.
