Abstract: A field experiment was conducted at Birsa Agricultural University, Ranchi, Jharkhand during rainy & winter seasons of 2015-16 and 2016-17. The experiment was laid out in randomized block design with 12 treatments i.e. haloxyfop 81 g/ha, haloxyfop 108 g/ha, haloxyfop 135 g/ha, haloxyfop 270 g/ha, fenoxaprop-p-ethyl 61.9 g/ha, quizalofop-ethyl 43.8 g/ha, imazethapyr 100 g/ha each applied at 20 DAS, pendimethalin 1000 g/ha, oxyfluorfen 100 g/ha each applied at 3 DAS, two mechanical, two hand weeding each performed at 25 and 45 DAS and weedy check, replicated thrice. Black gram var. Birsa Urd-1 was sown at 30 cm using 30 kg seed/ha fertilized with recommended level of nutrients N:P2O5:K2O:S i.e. 25:50:25:25 kg/ha. Two hand weeding at 25 and 45 DAS followed by two mechanical weeding at 25 and 45 DAS recorded higher plant population, nodule dry weight, seed yield and protein yield to the extent of 13.22, 10.00, 104.09 and 52.30 per cent, respectively as compare to weedy check i.e. 41.95 number/plant, 31.17 mg/plant, 621 kg/ha and 138.95 kg/ha, respectively. Among herbicides, application of haloxyfop 108 g/ha at 20 DAS recorded higher plant population, nodule dry weight, seed yield and protein yield.
