Optimization of Kalmegh (Andrographis paniculata Nees.) Cultivation through Plant Spacing and Nutrient Management

Kalmegh is being used form the immortal time for treating the cold, fever, snake bite, diabetics, liver diseases etc. An field experiment was conducted during kharif season of 2019-2020 at Horticulture Farm, Main Agricultural Research Station, College of Agriculture, University of Agricultural Sciences, Raichur, Karnataka, India, to study the response of plant geometry and integrated nutrient management on growth and yield of kalmegh. The experiment was laid out in a spilt plot design with 15 treatments and 3 replications. The results revealed that spacing of 30cm x 45 cm with imposition of 50% RDN + 50% vermicompost equivalent to recommended N found to be significantly higher number of primary branches and leaves per plant, leaf area and dry matter accumulation over the other treatments. The fresh and dry herbage yield per hectare were resulted in the significantly higher in the spacing of 30cm x 15 cm with the application of 50% RDN + 50% vermicompost equivalent to recommended N.
