Abstract

An investigation on “integrated nutrient management in kalmegh (Andrographis paniculata Nees.)” was carried out at Kittur Rani Channamma College of Horticulture, Arabhavi (Karnataka) under Ghataprabha Left Bank Command area during the year 2015­16 at Department of Plantation, Spices, Medicinal and Aromatic Crops. The result revealed that maximum plant height (61.13 cm) and plant spread (44.89 and 43.66 cm East-West and North-South, respectively), higher fresh herb yield per hectare (10.39 t) and andrographolide yield (2.25 q) was recorded with the application of 100:75:50 kg NPK per ha + Azatobacter (1 q) enriched in FYM (5 t ha-1) + vermicompost 1 t per ha at harvest. There was no significant variation in andrographolide content in plants.
