Abstract:
<em>Stevia rebaudiana</em> Bertoni is a shrub which is known for non-caloric natural sweetener called stevioside, which is the main component for its sweetness. The present experiment was conducted to analyze effect of concentrations of plant growth hormone (GA<sub>3</sub>) and nitrogen on growth, physiological parameters and yield in <em>Stevia rebaudiana</em>. The result revealed that at harvest (90 DAT), maximum internodal length and plant spread was recorded at G<sub>3 </sub>(500 ppm). The maximum leaf area and leaf area index was recorded at G<sub>2 </sub>(300 ppm). Whereas, the highest dry leaf yield per hectare (1.83 t) was recorded at G<sub>1 </sub>(Manual deflowering). At harvest, the maximum internodal length, leaf area, leaf area index and dry leaf yield per hectare (1.80 t) was recorded at 120 Kg N per hectare (N<sub>2</sub>).
