Abstract:

A field experiment was conducted during Kharif 2019 at MRS, Hebbal under AICRP on weed management, Bengaluru to evaluate different pre-emergence herbicides in kodo millet. The experiment consists of twelve treatments laid out in randomised complete block design. The experiment consisted of five pre-emergence herbicides (oxadiargyl, bensulfuron methyl + pretilachlor, butachlor, pendimethalin and atrazine) each at two different doses which were compared with weed free control and unweeded check. Among different pre-emergence herbicides, application of bensulfuron methyl 0.6 G + pretilachlor6.0 Gat 0.330 kg a.i. ha-1 at 3 days after sowing recorded lower total weed density and weed dry dry weight at 30, 60 and 90 DAS (5.72m-2, 1.41g m-2; 6.96 m-2, 2.06g m-2; 6.56m-2, 1.94 g m-2respectively). The same treatment also recorded higher weed control efficiency (59.21 %) without any phytotoxic effect on kodo millet. Good control of weeds at critical stage in this treatment produced higher grain (2225kg ha-1) and straw yield (4258 kg ha-1) which gave higher net returns (49363 Rs. ha-1) and B:C ratio (2.74), which was on par with bensulfuron methyl 0.6 G + pretilachlor6 Gat 0.165 kg a.i.ha-1. These pre-emergence herbicides have reduced the cost of cultivation producing higher profit under the present situation of labour scarce and high labour cost for weeding.
