Andrographis paniculata, commonly known as Kalmegh, is used both in Ayurvedic and Unani system of medicines because of its immunological, antibacterial and hepatoprotective properties. It is an annual herb has high value compound used in the treatment of the various diseases. A field experiment was conducted at the research farm of RAK College of Agriculture, Sehore (Madhya Pradesh) during Kharif 2015 & 2016. Investigations undertaken aiming to increase the growth and yield parameters of Kalmegh. Using different 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 effect of plant growth Hormones on Growth viz plant height (cm), leaf area (cm2), chlorophyll content, photosynthesis rate (μmol CO2 mˉ ² s-¬¹) at 90 DAS and yield viz test weight (g), seed yield (kg ha-1), herbage yield(q ha-1) and leaf alkaloid content (%) of kalmegh at harvesting. Foliar spray of GA3 @ 150 ppm, GA3 @ 100 ppm, cycocel@100ppm and GA3 100ppm significantly maximum the plant height (47.33), leaf area (420.82), chlorophyll content (57.78) photosynthesis rate (24.78) during 2015-16 and spray with GA3 @ 100 ppm, applies the maximum plant height (46.20) and leaf area (426.41) was significantly differed from other treatments during 2016-17. Significantly higher seed yield (521.03, 531.17), herbage yield (185.50 193.23) and leaf andrographolide alkaloid content (2.89, 3.02) was observed by treatment GA3 @ 100 ppm during both the year respectively.
