A field trial was conducted to monitor the impact of five isolates of Bacillus sp. viz. Bacillus licheniformis CKA1, Bacillus subtilis CB 8 A, Bacillus sp. RG1, Bacillus sp. S1 and Bacillus sp. S2 @ 109 CFU in combination with GA3 (25, 50 and 75 ppm) on plant growth, physiological parameters, yield and leaf nutrient status of strawberry cv. Chandler during the years 2013-14. The study showed significant effects of the treatments where the maximum plant height, leaf area, number of crowns per plant were recorded from T15, while the maximum plant spread in T12 and the number of runners per plant in T18. The number of fruits and yield were highest in T12 and lowest in control (T19). The physiological parameters viz. chlorophyll content in T9, rate of photosynthesis in T15 while stomatal conductance and transpiration rate in T18 were recorded maximum. Treatments also had significant effects on leaf nutrient contents in which maximum leaf nitrogen and manganese were recorded in T9, whereas phosphorus, calcium, magnesium, zinc in T18.The potassium was highest in T6 and iron, copper in T12. Study revealed that the PGPR can be used for sustainable fruit production.
