摘要: Spacing and irrigation levels influenced dry weight of leaves fresh stems significantly. Plant spacing 15 x cm produced higher herbage yields 707.8, 742.3 690.6 g.m−2 in well-watered control, mild severe water stress treatments, respectively. Low were recorded under 30 × 45 Among the andrographolide content was highest severely stressed plants. Increasing plant positively plants with wider (30 cm). In stems, 1.75% 15cm lowest 45cm no control. Similar trend noticed various treatments. Andrographolide yield from maximum control followed by conditions closer spacing. Lowest condition. Dry matter lower even spacing, but loss partly compensated its content. A. paniculata, increased accumulation compared to well watered may be attributed response signalling.
