Abstract:
This study was conducted at A field experiment was carried out in the research farm of RAK College of Agriculture, Sehore (Madhya Pradesh) during <em>Kharif</em> (2015-16). A field experiment consisting of Plant Growth Hormones Cycocel (100, 150 and 200 ppm), GA3 (100, 150 and 200 ppm) and NAA (100 and 150 ppm) and water spray as control to study the impact of plant growth Hormones on plant height, No. of branches, Fresh weight of leaf/plant, Dry weight of leaf/plant. Chlorophyll content, Photosynthesis rate, and leaf andrographolide content of Kalmegh (<em>Andrographis peniculata</em> Burn F. Ex). Significantly higher Photosynthesis rate was observed by treatment GA<sub>3</sub> 100 ppm (23.15) at 70 days of crop as compare to treatment GA<sub>3</sub> 150 ppm (22.43) respectively and Cycocel 100 ppm (57.72) at 70 days maximum Chlorophyll content recorded. The applied with NAA at 100 ppm (3.05% w/w) and GA<sub>3</sub> 150 ppm (2.93% w/w) was very effective and recorded maximum percentage of leaf andrographolide respectively. The foliar application of NAA 100 ppm at 90 days dry weight of leaf per plant maximum recorded (2.73 g/plant).
