Abstract
Tuberose, a valuable ornamental crop, requires optimized nutrient management to maximize its potential. With increasing concerns about chemical fertilizer usage, integrated nutrient management (INM) offers a sustainable alternative. This study investigated the effects of INM on Tuberose (Polianthes tuberosa L.) cv. Rajat Rekha, exploring combinations of organic and inorganic fertilizers to promote growth and productivity.
The results showed that integrated nutrient management significantly enhanced growth parameters. Specifically, the treatment combining 75% Recommended Dose of Fertilizer (RDF) with 2 kg Farm Yard Manure (FYM)/m2, 300g Vermicompost (VC)/m2, Phosphate Solubilizing Bacteria (PSB), and Azospirillum (T15) yielded superior results. This treatment reduced days to sprouting (12.10 and 14.18), and improved plant height (40.8 and 41.7 cm), leaf length (48.0 and 48.6 cm), leaf width (1.78 and 1.80 cm), and leaf number (60.8 and 61.4).
These findings suggest that integrated nutrient management can enhance Tuberose productivity while minimizing chemical fertilizer reliance. The identified optimal treatment combination offers a viable strategy for sustainable Tuberose cultivation, contributing to environmentally friendly agricultural practices. Future research can focus on scaling up these results and exploring potential applications in other ornamental crops.
