A field experiment was conducted in Instruction-cum-Research Farm of Assam Agricultural University, Jorhat district, Assam, India during 2014-15 and 2015-16 to identify a suitable combination of ginger and cowpea intercropping and weed management practice to effectively manage the weeds in ginger. A total of 16 numbers of treatment combinations were considered, comprising 4 legume inter-cropping systems and 4 weed management practices. Intercropping of legume crop Cowpea either in between rows of Ginger and incorporated at 40 days after sowing (DAS) or in between alternate rows of Ginger and incorporated at 40 days after sowing (DAS) and pre-emergence application of Metribuzin 500 g ai ha-1 + hand weeding (HW) at 70, 100 and 140 days after planting (DAP) recorded better results in terms of ginger growth and rhizome yield.
