Enhancement in yield and nutritive qualities of strawberry fruits by the application of organic manures and biofertilizers

•Use of biofertilizers along with organic manures was found promising to increase plant growth, yield and fruit quality of strawberry.•The biofertilizers gave superior results with combined application of FYM (50 %) and Vermicompost (50 %).•The PCA analysis revealed that ‘Days to flowering’ was independent and did not affect yield parameters.•Similarly, total acid content in fruits did not show any effect on other quality parameters of fruits including antioxidant capacity.
