Abstract: An investigation on " Effect of Weed Management Practices on Growth and Yield of Blackgram.” under adoptic and climatic condition of northern part of Madhya Pradesh was carried out during Kharif season of 2015 atthe Research Farm of the Department of Agronomy, College of Agriculture, Gwalior (M. P.). The experiment was laid a out in randomized block design (R.B.D.) replicated three timed with 12 treatments. Cyperusrotundus, Echinochloa crus-galli, Dectylecteniumagypticum & Acrachaneracemosa as narrow-leaf and Digeraarvensis, Commelinabenghalensis & Phylenthusniruri as broad-leaf were the weed species dominant and contributing about 96.29 per cent of the total weed flora.Weed control efficiency, weed index yield and harvest index were the higher under two hand weeding treatment at 20 & 40 DAS followed by PoE application of Imazethapyr + Imazamox (pre-mix) @ 80 g a.i./ha, PE application of Pendimethalin + Imazethapyr (pre-mix) @ 1000 g a.i./ha. However,The maximum net return and B: C ratio were under PE application of Pendimethalin+Imazethapyr (pre-mix) @ 1000 g a.i./ha (Rs. 34810/ha) over rest of the treatments followed by by PoE application of Imazethapyr+Imazamox (pre-mix) @ 80 g a.i./ha.
