Abstract:

Field experiment was conducted during rabi and summer, 2018-19 at wetland farm of S.V. Agricultural College, Tirupati, Andhra Pradesh. The experiment was laid out in a randomized block design with three replications. There were 10 treatments consisting of pre emergence application of atrazine @ 1.0 kg a.i ha-1 fb post emergence application of tembotrione @ 120 g, topramezone @ 30 g, halosulfuron methyl @ 67.5 g, 2, 4- D amine salt @ 580 g, tembotrione @ 60g + 2,4-D amine salt @ 290 g, topramezone @ 15g + 2,4-D amine salt @ 290 g, halosulfuron methyl @ 34 g a.i ha-1 + 2,4-D amine salt @ 290 g a.i ha-1, pre emergence application of atrazine @ 1.0 kg a.i ha-1 fb one HW at 30 DAS, hand weeding twice at 15 and 30 DAS and control. The higher kernel yield of maize was recorded with hand weeding twice at 15 and 30 DAS (T9), which was however comparable with application of atrazine @ 1.0 kg a.i ha-1 as pre emergence fb topramezone @ 30 g a.i ha-1 as post emergence (T3), atrazine @ 1.0 kg a.i ha-1 as pre emergence fb tembotrione @ 120 g a.i ha-1 as post emergence (T2), atrazine @ 1.0 kg a.i ha-1 as pre emergence fb one HW at 30 DAS (T1), without any significant disparity among them.
