| Abstract: |
Asparagus racemosus (Shatavari), a vital medicinal plant in traditional Indian medicine, exhibits notable phytochemical properties that can be amplified through targeted nutrient management. Chicken poultry manure, a rich organic source of essential macro- and micronutrients, has the potential to enhance phytochemical synthesis in medicinal plants. This study evaluated the effect of chicken poultry manure on the phytochemical composition of Asparagus racemosus roots through solvent extraction and analytical techniques. A controlled field experiment was conducted over two growing seasons using five manure application rates (0, 5, 10, 15, and 20 t/ha). Phytochemicals were extracted using methanol, ethanol, chloroform, and aqueous solvents, and quantified via GC-MS and HPLC. Application of poultry manure significantly increased total phenolic content (220.8±0.74 mg GAE/g), flavonoid content (219.2±1.8 mg QE/g), and saponins at 10–15 t/ha. Key bioactive compounds such as shatavarin IV, quercetin, rutin, and immunoside showed higher concentrations. Essential element analysis revealed optimal NPK ratios (3.5:2.8:1.8%) and substantial micronutrient levels. The findings suggest that strategic application of chicken poultry manure at 10–15 t/ha effectively enhances phytochemical biosynthesis in Asparagus racemosus, promoting sustainable cultivation practices while maximizing medicinal value. |
