Abstract: Medicinal and aromatic plants are major crops of domestic and industrial interest but a limiting factor in medicinal and aromatic crop production is weed interference. Weed infestation is one of the major constraints in kalmegh cultivation. Field experiments were conducted at Medicinal Plants Research and Development Centre (MRDC), G.B. Pant University of Agriculture and Technology, Pantnagar in 2015, to study the Effect of different weed control technique on weed persistence and yield attributing characters of kalmegh (Andrographis paniculata Nees). The treatments were Pre (Pendimethalin) and PoE (Quizalofop ethyl) herbicide, mechanical weeding, straw mulch, hand weeding along with Weedy check and weed free. All type of weeds (grassy, broad leaved and sedges) presented in experiment field. Weeds were effectively controlled by hand weeding than any other methods of weed control. Maximum dry matter accumulation per plant and other growth factors were observed in weed free treatment.
