AbstractStudies were conducted to determine the effect of vermicompost on growth, physiological disorders, fruit yield and quality of ‘Chandler’ strawberry. For this, 4 levels of vermicompost (2.5, 5.0, 7.5 and 10.0 t ha−1) were supplemented with inorganic fertilizers to balance fertilizer requirement of strawberry under semi-arid region of northern India. The vermicompost was incorporated into top 10 cm layer of soil, which was supplemented on the basis of chemical analysis, with amount of inorganic N, P, K fertilizer calculated to equalize the recommended dose of nutrients. Vermicompost application increased plant spread (10.7%), leaf area (23.1%) and dry matter (20.7%), and increased total fruit yield (32.7%). Substitution of vermicompost drastically reduced the incidence of physiological disorders like albinism (16.1–4.5%); fruit malformation (11.5–4.0%) and occurrence of grey mould (10.4–2.1%) in strawberry indicating that vermicompost had significant role in reducing nutrient-related disorders and disease like Botrytis rot, and thereby increasing the marketable fruit yield up to 58.6% with better quality parameters. Fruit harvested from plant receiving vermicompost were firmer, have higher TSS, ascorbic acid content and lower acidity, and have attractive colour. All these parameters appeared to be dose dependent and best results were achieved @ 7.5 t ha−1, however, beyond this dose of vermicompost, there was not significant influence on these parameters.
