Abstract
A field experiment was conducted during rabi season 2013-14, at College of Agriculture, V. C. Farm, Mandya. The experiment was laid out in RCBD with ten treatments and three replication. The treatments consist of four different herbicides butachlor, oxyfluorfen, oxadiargyl, bispyribac sodium and one pre mix formulation of bensulfuron methyl and pretilachlor. Among different herbicides, pre mix formulation of bensulfuron methyl at 60 g + pretilachlor at 600 g a.i. ha-1 as pre emergence application, recorded lower sedges, grasses, broad leaved weeds, total weed density (4.0, 13.0, 3.7 and 20.7/0.25 m2, respectively), lower dry weight (0.40, 1.80, 0.43 and 2.63 g/0.25 m2, respectively), lower weed index and higher weed control efficiency (91.57 %). This treatment registered significantly higher grain (4289 kg ha-1) and straw yield (6454 kg ha-1) which may be attributed to significantly higher plant height (86.80 cm), number of tillers (6.16 hill-1), dry weight of plant (42.43 g hill-1) at harvest and number of leaves (35.61 hill-1), leaf area (1432 cm2 hill-1) at 60 DAT, and higher yield attributing characters like number of productive tillers (4.52 hill-1), ear head length (16.58 cm), ear
head weight (54.73 g hill-1), test weight (3.02 g) and nutrient uptake (79.30, 15.00 and 58.61 kg nitrogen, phosphorus and potassium ha-1, respectively). This treatment also resulted in higher net returns (` 55,252 ha-1) and B:C ratio (2.95) and found mostbeneficial and comparable with the treatments intercultivation at 20 DAT followed by hand weeding at 30 DAT and pre-emergence application of oxyfluorfen 23.5 EC at 80 g a.i. ha-1 in transplanted finger millet.
