Studies on Character Association for Growth, Yield and Quality Components in Kalmegh (Andrographis paniculata Nees.)

An experiment was conducted on kalmegh to study the response of spacing and different fertilizer combinations in relation to growth, yield and quality of kalmegh. It was noticed that, spacing of 30cm×15cm with 50% RDN + 50% Vermicompost equivalent to recommended N resulted the significant increase in the herbage growth, yield and quality. The present investigation was found the correlation for various traits in kalmegh. Andrographolide content showed the positively high association with the plant height (0.86), number of secondary braches per plant (0.76), number of primary braches per plant (0.70) and fresh herbage yield per plant (0.68).
