The experiment on integrated nutrient management in strawberry was conducted with treatments comprising combinations of inorganic fertilizers, organic manure along with biofertilizers for growth, yield and soil nutrient status under open field conditions in Bundelkhand region. Among different treatment combinations, 50% RDF +50% Vermicompost + Azotobacter + PSB recorded maximum plant height (17.37 cm), plant spread (33.12 cm), leaves per plant (46.47), leaf area (45.85 cm2), total leaf chlorophyll content (2.72 mg/g), harvesting duration (68.67 days), fruit length (4.14 cm), fruit width (3.70 cm), fruit weight (16.03 g), number of fruits per plant (25.93), yield per plant (414.76 g) and yield per hectare (25.52 t). The TSS (8.83 oB), ascorbic acid (83 mg/100 g), TSS: Acid ratio (17.97), reducing (4.47%), non-reducing (1.90%) total sugars (6.38%), minimum titratable acidity (0.50%) and physiological loss in weight (14.58% on 5th day) was also obtained with 50% RDF +50% Vermicompost + Azotobacter + PSB. Whereas, minimum number of days taken for first flowering (42.67) and first harvesting (70) was recorded on the application of 75% RDF +25% Vermicompost + Azotobacter + PSB. However, significant increase in soil organic carbon (0.55%), available nitrogen (179.59 kg/ha), available phosphorus (14.62 kg/ha) and available potassium (324.35 kg/ha) were obtained with the application of 50% RDF +50% Vermicompost + Azotobacter + PSB and same treatment resulted in maximum (2.91) benefit: cost ratio. The principal component analysis showed that the PC1 accounts for 78.3% and PC2 accounts for 6.9% of total variance.
