Abstract:
A field study was conducted for two seasons in 2014-15 and 2015-16 in the ICR Farm of Assam Agricultural University, Jorhat-13, Assam, India with the objective to understand the effect of legume intercropping system in combination with different weed management practices on ginger rhizome and oil yield in acidic soil condition. There were total 16 numbers of treatment combinations, which comprised of four legume intercropping systems and four weed management practices. Amongst the legume intercropping system, Cowpea sown in between the rows of Ginger and incorporated into the soil at 40 days after sowing (DAS), recorded superior results in terms of stem girth of ginger plant, tillers per clump, leaves per tillers and rhizome parameters. Whereas, chemical weed management with Metribuzin 500 g ai ha^-1 plus hand weeding at 70, 100 and 140 days after planting (DAP) recorded better yield attributing parameters, contributing towards highest ginger rhizome and oil yield.
