Effects of Soil Nutrients, Cultivation Duration, and Planting Methods on Polysaccharides, Saponins, and Flavonoids in Asparagus cochinchinensis (Lour.) Merr.
Year: 2025
Type: article
Abstract: This study investigated how cultivation conditions affect bioactive compound synthesis in Asparagus cochinchinensis through a 3-year field experiment at two sites. Results showed that soil nutrient management significantly influenced metabolite accumulation, with mixed fertilizer treatment increasing polysaccharide content by 31.5% (reaching 5.84% dry weight) compared with controls. Different planting methods demonstrated varying impacts on plant establishment and compound synthesis, with raised bed systems achieving 92.8% establishment success and reducing pathogen populations by 34.2% compared with flat ground cultivation. Temporal analysis revealed that bioactive compound concentrations exhibited distinct seasonal patterns, with polysaccharides showing maximum accumulation in late autumn (5.84% ± 0.23%) and minimum levels during early summer (2.68% ± 0.12%). Principal component analysis indicated that environmental factors explained 68.4% of growth parameter variation and 57.2% of bioactive compound concentration variation. Strong correlations were observed between soil moisture content and root development (r = 0.815), whereas organic matter content showed significant positive correlations with both plant survival (r = 0.843) and metabolite synthesis. The study establishes optimal cultivation protocols combining nutrient management, planting method selection, and harvest timing to maximize both biomass and bioactive compound production.
