Abstract
Field experiment was conducted in a farmer's field at Kovakkulam village in Karur (Dt) to evolve the study on weed management in drip irrigated sunflower during February-May (2019). The experiment was laid out RBD with replicated thrice with eight treatments like Unweeded control, combination of hand weeding mulching with organic residues like paddy straw, sugarcane trash and pre-emergence herbicides like pendimethalin 30% EC and alachlor 50% EC. Among these combination of weed control treatments, pre-emergence application of pendimethalin 30% EC @ 2.5 l ha‑1 on 3 DAS + Mulching with sugarcane trash 10 DAS was recording higher values of growth and yield components such as plant height, LAI, DMP, head diameter, number of seed capitulum-1, oil content, seed yield (1932 kg ha‑1) etc. Unweeded control recorded the highest weed counts and weed biomass resulting in very low seed yield (610 kg ha‑1).
