Effect of pusa hydrogel and plant growth regulators on vegetative growth of strawberry (fragaria x ananassa dutch.) Cv. Chandler

Strawberry (Fragaria × ananassa Duch.) is a high-value fruit crop globally known for its rich nutritional profile and economic potential. However, its cultivation in India is challenged by shallow roots, low water retention soils, and environmental fluctuations. To ensure sustainable and profitable cultivation, innovations in water and nutrient management are critical. This study aimed to evaluate the individual and combined effects of Pusa hydrogel and plant growth regulators (Triacontanol and Cycocel) on the vegetative growth, flowering, fruiting, yield, and quality of strawberry cv. Chandler. It also assessed the economic viability of these treatments. The research was conducted over two growing seasons (2021–22 and 2022–23) at Shri Durga Ji Post Graduate College, Azamgarh, U.P., using a Randomized Block Design with 27 treatments replicated thrice. The treatments included various concentrations and combinations of Pusa hydrogel (25g, 50g), Triacontanol (100ppm, 150ppm), and Cycocel (500ppm, 1000ppm). Data were collected on plant height, number of leaves, plant spread, flowering time, fruit size and weight, yield per plant, and biochemical quality traits like TSS, sugars, and vitamin C content. Economic analysis was also performed. Treatment T20 [Triacontanol 170 ppm + Pusa hydrogel 60 g] showed the best performance in vegetative traits, including plant height (19.93 cm), highest number of leaves (15.43), plant spread (23.2cm), days taken to first flower (60.02 days) and number of flowers (25.43). The synergistic application of Pusa hydrogel and plant growth regulators significantly improved strawberry growth, yield, fruit quality, and economic returns. This approach offers a sustainable and resource-efficient strategy for strawberry cultivation, particularly in water-limited regions.
