Influence of organic manures and fertilizers on growth, yield and quality in kalmegh (Andrographis paniculata Wall. Ex. Nees.)

Abstract

A field experiment entitled “Integrated nutrient management in kalmegh (Andrographis paniculata Nees.)” was conducted in late kharif season, 2018-19 at Main Horticultural Research and Extension Centre (MHREC), University of Horticultural Sciences, Udyanagiri, Bagalkot, to evaluate the performance of different doses of organic manures and chemical fertilizers under the prevailing conditions of Bagalkot, with 24 treatments and three replications. Among different combinations application of 25 tonnes of FYM + 1.0 tonne of vermicompost + 75:75:50 kg NPK per hectare had beneficial effect on growth, yield and quality parameters. Significantly highest plant height (65.67 cm), number of leaves (105.38), number of branches (47.97) per plant and higher fresh herbage yield (21.47 t/ha) and dry herbage yield (7.64 t/ha) were noticed. There was no significant variation in andrographolide content in plants.
