Growth and yield performance of strawberry (Fragaria ananassa) under various doses of vermicompost and NPK fertilizers grown at rooftop of Charfasson area in the southern parts of Bangladesh

A pot experiment was carried out on the rooftop of a building at Charfasson town Bhola to evaluate growth and yield performance strawberry (Fragaria ananassa) as influenced by different doses vermicompost inorganic fertilizers in winter season 2020-2021. Each filled with ten kg soil arranged completely randomized design having seven treatments three replications. Treatments were T1: Control (-VC), T2: 5 t VC/ha, T3: 10 T4: 15 T5: 20 T6: 25 T7: 50% RDF NPK (40 - 15-25 kg/ha). Different agronomic parameters measured intervals 30, 60, 90, 120 days after sowing seeds. All showed better responses than control treatment. Among them, T5 treatment tends show significantly (p<0.05) higher plant height (18.5 cm), number leaf (54/plant), root length (15.50 first flowering (at 61 days), fruit (5.75 diameter (13.75 fruits (15/plant), average weight (14.50 g), fresh (13.59 t/ha), (10.41 g/plant), reproductive structure (3.12 dry g/plant) benefit-cost ratio (9.37). T6 area (49.00 cm2), petiole (4,61 (2.20 (5.87 (1.42 biomass (12.48 g/plant). T2, T3 T4 T7 The overall findings revealed that application (20 t/ha) might be suitable method gardening achieve its southern parts Bangladesh.
