Abstract: Present study was carried out during 2019-20, at College of Agriculture, Vellayani, Thiruvananthapuram, Kerala with an objective to standardise an economic weed management strategy for Bajra Napier Hybrid. The experiment was laid out in randomized block design (RBD) with 9 treatments in three replications. The variety used for the study was Suguna, released from Kerala Agricultural University. Analysis of data showed that weed management practices had significant effect on yield and nutrient uptake of BN hybrid. The treatment oxadiargyl 90 g ha^-1 on 3-5 DAP fb hand weeding on 25 - 30 DAP recorded the highest green fodder yield and dry fodder yield. An increase of about 47.14 % in green fodder yield was recorded in oxadiargyl 90 g ha^-1 on 3-5 DAP fb hand weeding on 25 - 30 DAP over weedy check. Significantly higher nitrogen, phosphorus and potassium uptake were observed with the application of oxadiargyl 90 g ha^-1 on 3-5 DAP fb hand weeding on 25 - 30 DAP.
