Effect of Maize (Zea mays L.) and Legume Intercropping Systems on Weed Dynamics

The field experiments were conducted during two consecutive seasons of kharif (June to October), 2016 and 2017 at the Experimental Research Farm, ICAR Complex for NEH Region, Nagaland Centre, Medziphema, Nagaland, India. treatments consisted four planting geometries i.e. maize+black gram (1:1), (2:2), maize+soybean (1:1) (2:2) three weed management practices weedy check, pre-emergence application pendimethalin @ 1.0 kg a.i. ha-1+one hand weeding (1HW) 30 DAS weedings (2HW) 20 40 DAS. experiment was laid out in Randomized Block Design with factors comprising twelve treatment combinations replicated times. results revealed that among geometry, recorded highest control efficiency (WCE) reduced population, fresh weight dry monocot dicot 60 gave maximum maize equivalent yield (4374.96 ha-1). Among management, 2HW lowest weight, as 4591.10 ha-1 which par ha-1+1HW 4461.80 ha-1. net return (` ha-1), per rupee invested B: C ratio from ` 36624.05 closely followed by Rs. 35428.81
