Abstract
The field investigation with different combinations of organic manures and inorganic fertilizers were undertaken to know information on “Integrated nutrient management in kalmegh (Andrographis paniculata Wall. Ex. Nees.)” at Main Horticultural Research and Extension Centre (MHREC), UHS, Udyanagiri, Bagalkote, during 2018-19. The experiment was conducted on CIM-Megha variety and it was laid out in factorial randomized block design with 24 treatments involving different combination of organic manures and inorganic fertilizers with three replications. The three main factors considered having different levels in which 3 levels of FYM (M0, M1 and M2, respectively), 2 levels of Vermicompost (V0 and V1) and 4 levels of nitrogen, phosphorous and potassium (F0, F1, F2 and F3, respectively), Among the different treatment combinations, application of 25 t FYM, 1 t vermicompost along with 75: 75: 50 kg NPK per ha (M2V1F3) recorded significantly maximum plant height (65.67 cm), number of leaves per plant (105.38), number of branches per plant (47.97), LAI (2.53), CGR (0.18 g m-2 day-1), RGR (13.07 mg day-1), NAR (0.74 mg day-1 m-2), lower available N and K (41.63 and 23.63 kg ha-1), N and P uptake (126.65 and 26.53 kg ha-1), total dry matter production (12.92 g plant-1), fresh herbage yield (21.47 t ha-1), dry herbage yield (7.64 t ha-1) and the highest benefit cost ratio (3.29) were recorded.
Significantly maximum andrographolide content (4.41%) was recorded with the application of 25 t FYM along with 1 t vermicompost (M2V1F0). Hence, it can be concluded, that Andrographis paniculata Wall. Ex. Nees. variety CIM-Megha has shown better performance under dry land situation with application of 25 t FYM, 1 t vermicompost along with 75: 75: 50 kg NPK per ha (M2V1F3) in terms of growth, yield, economics and soil health. Whereas, application of 25 t FYM along with 1 t vermicompost (M2V1F0) performed better in terms of quality (andrographolide content %).
