Abstract: An experiment was conducted to investigate the effective use of plant growth promoting rhizobacteria (Bacillus licheniformis CKA 1, Bacillus subtilis CB 8 A, Bacillus sp. RG1, Bacillus sp. S₁ and Bacillus sp S₂) on growth, yield and fruit quality of strawberry cv. Chandler at Model Farm of Directorate of Research, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, India during 2012-2013. It was observed that the root+ foliar application of plant growth promoting rhizobacteria gave the best results with respect to growth, yield and fruit quality as compared to other application methods. The maximum plant height and spread were recorded in T₃ whereas the maximum leaf area, chlorophyll content, rate of photosynthesis, stomatal conductance and transpiration rate were observed in T₁₅. The number of crowns were maximum in T₉ followed by T₁₅, while the number of runners were significantly more in T₁₂ showing significant improvement over control. The highest number of fruits and yield per plant were highest in T₁₅, respectively. The maximum fruit weight and length were recorded from T₁₅ while fruit diameter was maximum T₃. The maximum fruit TSS in T₁₃, TSS: acid ratio in T₄, acidity in control over other treatments. Total sugars in T₁₀, Reducing Sugars were highest in T₇ the as compared to other treatments. The ascorbic acid content was highest in T₁₆ while anthocyanin content was maximum in T₁ as compared to other treatments.
