Effect of weed management practices on transplanted finger millet (Eleusine coracana L.) in Bihar

Abstract

A field experiment was conducted at Research Farmland, Bihar Agricultural University, Sabour, Bhagalpur, Bihar during kharif season of 2019 to evaluate weed management practices in transplanted finger millet. The experiment was laid out in randomized block design with three replication and consisting eleven treatment viz., T1 (Weedy check), T2 (Hoeing at 20 and 40 DAT), T3 (Pendimethalin @ 750 g ai ha-1 as pre-emergence), T4 (2, 4- D @ 750 g ai ha-1 as post-emergence), T5 (Bispyribac sodium @ 20 g ai ha-1 as post-emergence), T6 (Pendimethalin @ 750 g ai ha-1 as pre-emergence fb 2, 4-D @ 750 g ai ha-1 as post-emergence), T7 (Pendimethalin @750 g ai ha-1 as pre-emergence fb Bispyribac sodium @ 20 g ai ha-1 as post-emergence), T8 (Pretilachlor @1000 g ai ha-1 as pre-emergence), T9 (Pretilachlor @1000 g ai ha-1 as pre-emergence fb 2, 4- D @ 750 g ai ha-1 as post- emergence), T10 (Pretilachlor @1000 g ai ha-1 as pre- emergence fb Bispyribac sodium @ 20 g ai ha-1 as post- emergence) and T11 (weed free). The results revealed that sequential application of Pretilachlor @1000 g / Pendimethalin @750 g ai ha-1 as pre-em fb Bispyribac sodium @ 20 g ai ha-1 as post-emergence for higher yield, net return and B:C ratio of transplanted finger millet in Bihar.
