Abstract: A field experiment was conducted during rabi 2017-18 at Central Research Station, OUAT Bhubaneswar to assess the efficacy of conventional and herbicidal approach on weed flora in groundnut. The experiment was laid in a randomized block design with fourteen treatments replicated thrice. Uncontrolled weed growth throughout the crop season resulted in yield loss of about 54.4% in rabi groundnut. Digitaria ciliaris, Digitaria sanguinalis Eleusine indica, Dactyloctenium aegyptium, Panicum maximum among grasses, Borreria hispida, Cleome rutidosperma, Croton sparsiflorus, Tephrosia purpurea, Phyllanthus niruri, Celosia argentea among broadleaved weeds and Cyperus rotundus, the only sedge were the predominant weeds found in the experimental plot. Amongst the herbicidal treatments, pre-emergence application of oxyfluorfen @ 0.05kg/ha (PE) +1 Handweeding at 20 DAS significantly reduced the weed density (27.90 number/m2), weed dry weight (50.50 g/m2) and showed the highest weed control efficiency.(84.6%).
