Abstract:
The current research entitled “Effect of different weed management practices on productivity and economic of Niger (Guizotia abyssinica)” during kharif season of 2020, it was carried out at the Instructional cum Research Farm, DKS College of Agriculture and Research Station, Bhatapara with the objective of studying the effect of different weed management practices on Niger yield. The soil in the experimental field had a medium texture and levels of N, P₂O₅ and K₂O that were low, medium and high respectively. The climate is sub-humid to semi-arid in the region Niger was sown on 20^thAugust, 2020 in randomized block design with 3 replication and 8 treatments i.e. Pendimethalin @ 0.75 kg a.i. ha^-1 as pre emergence (T1), Pendimethalin @ 0.75 kg a.i. ha^-1 as pre emergence + One hand weeding at 40 DAS (T2), Quizalofop ethyl @ 37.5 g a.i. ha^-1 as early post emergence (15-20 DAS) (T3), Quizalofop ethyl @ 37.5 g a.i. ha^-1 as early post emergence (15-20 DAS) + wheel hoe at 40 DAS. (T4), Fenoxaprop-p- ethyl 9.3% EC @ 37.5 g a.i. ha^-1 as early post emergence (15-20) DAS (T5), Fenoxaprop-p-ethyl 9.3% EC @ 37.5 g a.i. ha^-1 as early post emergence (15-20 DAS) + Wheel hoe at 40 DAS. (T6), Weed free (T7) and Weed free (T8). Niger variety BN-1 was sown at 30 × 10 cm spacing using seed 10 kg ha^-1 with recommended level of nutrients 20:20:10 kg ha^-1 N: P₂O₅: K₂O. On the 20th November, 2020 the crop was harvested.
