| Description |
During 2008 and 2009, field experiments were conducted at the research farm of CSIRInstitute
of Himalayan Bioresource Technology, Palampur, India to assess the effect of shade
levels (no shade, 25% shade, 50% shade, 75% shade) and plant geometry levels {30 × 15 cm
(north-south, N-S), 45 × 10 cm (N-S), 30 × 15 cm (east-west, E-W) and 45 × 10 cm (E-W)}.
Plants development was fastest in controls and slowest in stevia plants growing at minimum light
(75% shade). These plants showed delayed bud formation and flowering. Significantly higher
dry leaf yield was recorded when the crop was grown under 25% shading as compared to 50 and
75 % shade. Total steviol glycosides content decreased with increasing shade levels. All shade
levels resulted in the same leaf to stem ratio, which was significantly higher than obtained under
ambient light. Plant geometry significantly affected number of leaves and leaf dry weight plant–1.
During both the years, dry leaf weight was highest in wider row spacing (45 × 10 cm) as

compared to narrow row spacing (30 × 15 cm). Stevia spaced at 30 × 15 cm in E-W direction
recorded significantly highest total steviol glycosides at 2 months after transplanting (MAT).
