Abstract:
Field experiment was conducted at Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirapalli during Kharif, 2018 to evaluate the weed management practices in transplanted finger millet under sodic soil. The weed management practices viz., pre emergence (PE) application of pendimethalin 30 EC at 750 g/ha, oxyfluorfen 23.5 EC at 50 g/ha, bensulfuron methyl 0.6 G at 60 g/ha + pretilachlor 6 G at 600 g/ha, early post emergence (EPOE) application of bispyribac sodium 10 SC at 25 g/ha, PE pendimethalin 30 EC at 750 g/ha fb EPOE bispyribac sodium 10 SC at 25 g/ha, PE oxyfluorfen 23.5 EC at 50 g/ha fb EPOE bispyribac sodium 10 SC at 25 g/ha, PE bensulfuron methyl 0.6 G at 60 g/ha + pretilachlor 6 G at 600 g/ha fb EPOE bispyribac sodium 10 SC at 25 g a.i/ha, PE oxyfluorfen 23.5 EC at 50 g/ha fb hand weeding on 30 DAT, Hand weeding on 15 and 30 DAT and unweeded control. The results revealed that the lowest total weed density, total weed dry weight and higher WCE were registered in PE application of bensulfuron methyl 0.6 G at 60 g/ha + pretilachlor 6 G at 600 g/ha fb EPOE application of bispyribac sodium 10 SC at 25 g/ha and it was followed by hand weeding on 15 and 30 DAT. The highest grain and straw yield were also registered in PE application of bensulfuron methyl 0.6 G at 60 g/ha + pretilachlor 6 G at 600 g/ha fb EPOE application of bispyribac sodium 10 SC at 25 g/ha and it was on par with hand weeding on 15 and 30 DAT.
