A total of ten treatments were evaluated in a randomized block design (RBD) with three replications on sandy loam soils of Tirupati, Andhra Pradesh. The treatments comprised of pre-emergence herbicides (alachlor 1000 g ha-1 and atrazine 1000 g ha-1) followed by post-emergence herbicides (Halosulfuron-methyl 67.5 g ha-1, Tembotrione 100 g ha-1 and 2,4-D sodium salt). Among the different pre-and post-emergence herbicides applied, pre-emergence application of alachlor 1000 g ha-1 fb post-emergence application of halosulfuron-methyl 67.5 g ha-1 + tembotrione 100 g ha-1 imposed to maize resulted in higher number of yield attributes which ultimately results in higher grain yield. Unweeded check recorded the lowest values, which was due to severe weed competition. The yield reduction due to unweeded check accounts to 53.91 and 53.44 per cent.
