Abstract:

The present investigation was carried out during 2016-17 and 2017-18 at Bidhan Chandra Krishi Viswavidyalaya to study the effect of different plant growth regulators (PGRs) on growth, yield and quality of strawberry (Fragaria × ananassa Duch.) cv. Winter Dawn, grown under shade net. The experiment was laid out in RBD, replicated 3 times with nine treatments, viz., GA3 (20 and 40 ppm), NAA (20 and 40 ppm), Cycocel (500 and 750 ppm), BA (25 and 50 ppm) and Control (water spray), applied as foliar spray at 15 and 30 DAP. Significant differences were observed with respect to growth, yield and quality of strawberry. The results revealed that, application of GA3 @ 40 ppm significantly improved vegetative growth, flowering, fruiting parameters over control, while Cycocel @ 750 ppm resulted in earlier flower initiation (29.36 vs. 43.13 days) and improved fruit weight (24.05 vs. 17.78 g). However, GA3 @ 40 ppm resulted in significantly highest productivity (2.68 t/ha) and fruit quality in terms of TSS (6.48 0Brix), TSS:acid ratio (10.29), ascorbic acid (57.35 mg/100 g pulp) and anthocyanin content (65.68 mg/100 g pulp). The estimated benefit: cost ratio (B:C) was highest (2.92:1) for GA3 @ 40 ppm, followed by GA3 @ 20 ppm (2.63:1). From this study, foliar spray of GA3 @ 40 ppm at 15 and 30 days after planting was recommended as cost-effective treatment for improvement of plant growth, productivity and fruit quality of strawberry grown in the Gangetic alluvial region of West Bengal.
