Enhancing acclimatization of in vitro-propagated turmeric (Curcuma longa Linn.) in soilless systems
Abstract
Acclimatizing in vitro-propagated turmeric presents challenges and opportunities. This study evaluated the growth performance and survival of in vitro-propagated turmeric acclimatized in soilless systems using varying seaweed extract concentrations (0.5, 0.75, 1.0, and 1.5 mL) in a factorial completely randomized design (CRD). Aeroponic systems significantly enhanced growth parameters (plant height, stem diameter, leaf number, leaf area) compared to hydroponic systems, due to improved oxygen availability and nutrient uptake. 1.0 mL seaweed extract further optimized growth, showing the highest values for plant height, stem diameter, and leaf area. A significant interaction between acclimatization system and seaweed extract concentration was observed; aeroponics with 0.75 mL seaweed extract yielded the tallest plants and largest leaf area. Aeroponics also resulted in superior root development and significantly higher biomass accumulation than hydroponics. The highest biomass was achieved with 1.0 mL seaweed extract. A 100% survival rate across all treatments confirmed turmeric’s adaptability to soilless systems. These findings highlight the synergistic benefits of aeroponics and moderate seaweed extract supplementation for optimizing in vitro-propagated turmeric acclimatization and growth.
