Abstract

An experiment to study the efficacy of weedicides in Kodo millet was conducted at Zonal Agricultural Research Station, University of Agricultural Sciences, GKVK, Bengaluru during Kharif 2018 and 2019 on weed density and yield parameters. The extent of yield reduction owing to weed is 33-50% in nutri cereals depending on the intensity and persistence of weed density. To find out the effective pre and post emergent weedicides for Kodo millet, a promising nutri cereal crop, the experiment was conducted and was laid in RCBD comprising 12 treatments. Among the herbicide treatments, the grain yield at the treatments of bensulfuron methyl 0.6 G + pretilachlor 6.0 G @ 165 g a. i. ha-1 followed by bispyribac sodium 10 SC @ 10 g a. i. ha-1 (1958 kg ha-1) and bensulfuron methyl 0.6 G + pretilachlor 6.0 G @ 165 g a. i. ha-1 followed by ethoxysulfuron 15 WG @ 12 g a. i. ha-1 (1940 kg ha-1) were found significantly higher to other treatments and were at par with treatment weed free check

Conclusion

Kodo millet is relatively a long duration crop as compared to other nutria cereals and hence provides greater scope for weed control during early growth stages of the crop. As vegetative growth of crop is more, pre as well as post emergent herbicides also plays a foremost role in effective control of the weeds. The present study concluded that the application of bensulfuron methyl 0.6 % G + pretilachlor 6.0 % G 165 g a. i. ha-1 as pre-emergent herbicide fb post emergent application of bispyribac sodium 10 % SC 10 g a. i. ha-1 is more beneficial owing to broad spectrum control of weeds more efficiently and thereby enhanced the yield of kodo millet.
