| dc.description.abstract | An experiment entitled “Evaluation of pre and post-emergence herbicides for weed management in irrigated maize (Zea mays L.)” was conducted during kharif, 2012 at Main Research Station, Hebbal, Bangalore. Fourteen treatments [topramezone 33.6 SC (16.8, 21.0 and 25.2 g a. i. ha-1) + atrazine 50 WP (250 g a. i. ha-1) with and without MSO adjuvant (2 ml lit-1), topramezone (25.2 g ha-1), tembotrione 42 SC (105 g a. i. ha-1) + isoxadifen-ethyl 21 SC (52 g a. i. ha-1) at 15 DAS, atrazine (1000 g ha-1) at 3 DAS, oxyflurofen 23.5 EC (200 g a. i. ha-1) and pendimethalin 30 EC (750 g a. i. ha-1) at 3 DAS followed by 2, 4-D Na 80 WP (500 g a. i. ha-1) at 30 DAS, two intercultivations, hand weedings (20 and 40 DAS) and weedy check] were replicated thrice in RCBD. Major weeds observed were Cyperus rotundus, Cynodon dactylon, Ageratum conyzoides and Cleome monophylla. Oxyflurofen- 200 g ha-1 + 2, 4-D Na-500 g ha-1 recorded significantly higher kernel yield, net returns and B:C ratio (6107 kg ha-1, Rs. 61,013 ha-1 and 3.35) followed by two hand weedings (6081 kg ha-1, Rs. 57,790 ha-1 and 3.00) and topramezone - 25.2 g ha-1 + atrazine – 250 g ha-1 (5864 kg ha-1, Rs. 58,887 ha-1 and 3.38) compared to atrazine -1000 g ha-1 (4638 kg ha-1, Rs. 41,981 ha-1 and 2.71) and weedy check (2157 kg ha-1, Rs. 8,238 ha-1 and 1.35) without any phytotoxicity on maize. | en_US |
