Online Published on 22 June, 2023. Abstract Kalmegh is well recognized for its medicinal and pharmacological uses. It is used in differentsystems of medicine and exhibits anti-malarial, anti-diabetic, anti-pyretic, hepatoprotective,anti-inflammatory and anticancerous properties etc.. The major limiting factor in cultivation ofkalmeagh is the high infestation of weed which ultimately affects the yield of produce. Presentinvestigation was conducted to check the effect of different colour mulches (white, black and silver) on growth and yield of kalmegh (Andrographis paniculata Nees). The results revealed that there are significant differences in plant height (cm), number of leaves per plant, number of branches per plant, leaf area per plant and dry matter content per plant (g) using black colouredmulch as compared to control. Thus, application of black colour mulch can be a good floormanagement option for controlling weed infestation and for obtaining high yield in kalmegh.
