- Abstract
Field experiments were conducted during summer and kharif, 2017 to evolve a suitable weed management programme for irrigated hybrid maize. The experiments were laid out in randomised block design, replicated thrice with ten treatments viz., unweeded control, twice hand weeding on 20 and 40 DAS, pre-emergence application of atrazine 1.0 kg/ha, metribuzin 1.0 kg/ha, post emergence application tembotrione 100 g/ha, topramezone 75 g/ha and combinations of pre and post emergence herbicide application. From the results, it is concluded that pre-emergence application of atrazine 1.0 kg/ha on 3 DAS followed by post-emergence application of tembotrione 100 g/ha on 21 DAS was recorded the least weed count, weed biomass, nutrient removal by weeds and the highest weed control index, growth parameters, yield parameters and yield and proved to be an efficient and economically feasible technology to manage the weeds and to realize better returns from the irrigated hybrid maize.
