The present investigation was carried out during 2010-2012 to find out the effect of integration of bio-fertilizers with organic manures and inorganic fertilizers on growth, yield and quality of strawberry (Fragaria × ananassa Duch.) cv. Festival. The growth, yield and quality of strawberry fruits were significantly influenced by integration of bio-fertilizers, organic manure and inorganic fertilizers. The maximum growth in terms of plant height, spread and number of crowns/plant were observed in the treatment consisting of 75 % RDF + vermicompost + Azospirillum +PSB + 50 ppm GA3+ 50 ppm BA. This treatment also exhibit superiority in yield attributing characters like number of runners/plant, berry set percentage, berry weight, number of berries/plant and yield/ha. The quality parameters of the fruit like TSS, titrable acidity, ascorbic acid, total sugars and reducing sugars were also influenced by combined use of organic, inorganic and biological sources of nutrients. Significant to highly significant positive correlation was observed among different growth and yield attributing characters with yield.
