Nutrient Uptake under Inter-Cropping Systems of Ginger and Cowpea and Weed Management Practices
Year: 2018
Type: article
Abstract: A field experiment was conducted in Assam Agricultural University, Jorhat district, Assam, India to understand the effectiveness of inter-cropping system and chemical weed management on nutrient uptake by ginger (Zingiber officinale Rosc.), inter-crop and weeds, during 2013-14 and 2014-15. There were 16 numbers of treatment combinations, comprising of 4 inter-cropping systems and 4 weed management practices. Intercropping of Cowpea in between rows of Ginger and incorporated at 40 days after sowing (DAS) and treatment with Metribuzin 500 g ai ha-1 + hand weeding (HW) at 70, 100 and 140 days after planting (DAP) recorded better results in terms of crop yield and nutrient uptake by ginger and cowpea. On the contrary, weedy check recorded the highest nutrition uptake by weeds at almost all the considered time intervals. At the time of ginger harvest, treatments Ginger + Cowpea (2:1) and Cowpea incorporated at 40 DAS and Hand weeding (HW) at 40, 70, 100 and 140 DAP recorded better results in terms of P2O5 and K2O availability in soil.
