The experiment was laid out according to Randomized Blocks Design with fourteen treatment replicated thrice. The result reveals that the maximum plant height (21.06 cm), plant spread (23.89 cm), number of leaves (18.69), leaf area (78.45 cm2), crown diameter (1.40 cm), internodal length (7.09 cm), number of flowers/plant (19.58), number of fruits/plant (17.71), number of fruits/truss (4.89), berry length (3.85 cm), berry breadth (2.84 cm), berry weight (14.74 g), marketable fruit (83.04%), number of harvest (5.73), yield/plant (260.93 g), TSS (9.16 oBrix), TSS/acid ratio (14.77), ascorbic acid (58.30 mg/100 gm), anthocyanin (63.72 mg/100 gm), leaf nitrogen content (3.20%), phosphorus content (1.20%) and potassium content (3.07%) were recorded in plants treated with treatment T9 (Vermicompost + Azotobacter + PSB). The minimum days taken in flowering (54.77 days) and minimum titratable acidity (0.62%) were also recorded in treatment T9 (Vermicompost + Azotobacter + PSB). Considering overall performances, the study revealed that the combined application of Vermicompost and biofertilizer could be a good source of plant nutrients for organic strawberry cultivation.EnglishThesis
