Year: 2019
Type: article
Abstract: The study was conducted in order to identify the weed species in onion fields in Chhattisgarh plain. An experiment was conducted during rabi season (October-March) of 2008-2009 to find out the effect of weed management practices on growth and yield of onion, weed dynamics and economics. Onion variety “Nasik Red” was grown as a test crop and transplanted on 20th November 2008 with spacing 15x10 cm. A total of seven weed species belonging to seven family were identified in onion field that were surveyed. The maximum weed density (20.62%) was recorded with Parthenium hysterophorus followed by Cyperus rotundus (19.35%) and Cynodon dactylon (19.00%). The treatment Oxyflourfen @ 0.20 kg ha-1 pre-transplanting+ Hand Weeding at 20 DAT resulted in greater plant height, weed control and yield under Chhattisgarh plains situation.
