Wall. ex Nees.” were conducted in the experimental farm as well as laboratory of Department of Forest Products, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2021-2022. Morphological studies conducted in the experimental field and laboratory revealed that Andrographis paniculata was found to be an annual, branched and erect herb. The stem was found to be branched, quadrangular with longitudinal furrows. Leaves were opposite, decussate, lanceolate, glabrous with acute tip and entire margin. The plant had adventitious roots with length ranged for 14-20 cm. Inflorescence was axillary panicle and flowers were found to be small, white in color with purple or violet markings. The fruit was capsule, linear and oblong in shape and acute at both ends and the seeds were small, round or ovoid. Among various organic manures and fertilizers combinations treatment T2 (NPK @ 60:45:30 kg/ha) excelled over other treatments for all the growth and yield parameters i.e. plant height (46.98 cm), plant spread (30.07 cm2), number of branches per plant (19.89), number of leaves per plant (92.39), fresh stem weight per plant (20.30 g), dry stem weight per plant (12.90 g), fresh leaf weight per plant (13.87 g), dry leaf weight per plant (7.47 g), fresh above ground biomass per plant (35.29 g), dry above ground biomass per plant (20.70 g), estimated fresh above ground biomass (26.12 q/ha) and estimated dry above ground biomass (15.32 q/ha) which was followed by T7 (Vermicompost @ 3.3 t/ha + PK @ 45:30 kg/ha) and minimum values were recorded in control i.e. (T1). However, in case of interaction effect between organic manures, fertilizers and harvesting stages maximum values for estimated fresh above ground biomass (30.82 q/ha) and estimated dry above ground biomass (18.95 q/ha) were recorded in treatment combination T2H2 (NPK @ 60:45:30 kg/ha at Flowering stage). Economic analysis revealed that NPK (60:45:30 kg/ha) had the highest benefit cost ratio of 2.06 which was followed by Jeevamrit + PK (45:30 kg/ha) i.e. 1.59 and minimum was recorded in controlEnglishThesis
