SEEMA KUMARI and KULDEEP MEHTA. 2018. Effective use of GA3 and plant growth promoting rhizobacteria on growth, fruiting and physico-chemical characteristics of strawberry cv. chandler. Green Farming Vol. 9 (3) : 481-485 ; May-June, 2018

ABSTRACT
A field trail was conducted to evaluate the effect of GA3 (25, 50 & 75 ppm) and plant growth promoting rhizobacteria (Bacillus licheniformis CKA 1, Bacillus subtilis CB 8A, Bacillus sp. RG1, Bacillus sp. S1 and Bacillus sp. S2) on growth, fruiting and physico-chemical characteristics of strawberry cultivar 'Chandler' during 2013-14. Study has shown that the plant growth promoting rhizobacteria (PGPR) alongwith GA3 @ 75 ppm found to be best treatments in terms of increased growth, fruiting and physico-chemical characteristics. The maximum plant height (31.00 cm), leaf area (137.95 cm2), number of crowns per plant (5.17) and plant biomass on dry weight basis (13.37 g/ plant) were recorded in T15, while the maximum plant spread (47.17 cm) in T12, the number of runners per plant (33.71) in T18 and plant biomass on fresh weight basis (44.02 g/ plant) in T6. Furthermore, the duration of flowering (111 days), number of fruits (24/ plant) and yield (586.57 g/ plant) were maximum in T12 while harvesting duration (43.89 days) was maximum in T3 as compared to other treatments. The maximum fruit weight and length were recorded in T15 (24.74g and 50.38 mm respectively) while, fruit diameter (33.37 mm), ascorbic acid content (73.65 mg/ 100g) and total sugars (7.43%) were found maximum under T6 and anthocyanin content (42.40 mg/100 ml) in T8. TSS were highest in T10 (10.07 0Brix) and acidity in T15 (2.18 %) whereas, the TSS: acid ratio was recorded highest in T16 (8.51).
